I am trying to model a surface that is in contact with water. As far as I know, the main heat transfer mechanism in this case is convection (forced or natural depending on the state of the water) and the heat exchange between water and the surface depends on the area of the surface, the temperature difference and the convection coefficient (I know that the calculation of the coefficient is tricky and depends on many variables). My question is, is there an in-built facility that allows the user to change the convection coefficient for an external surface? From what I have seen so far, the user can alter the internal convection coefficient of a surface from "Zone composition -> Convection coefficients". I know that superimposing a new convection coefficient won't solve my problem, however I believe it is a good place to start.

One user noticed that a custom script controlling the res module needed to be revised. If you are using scripts that access items in long lists then you may wish to confirm whether your script needs to be revised. Background: We noticed there was a lot of wrist movement involved in navigating, long lists in the interface (like a constructions database with 100 items). After testing we adjusted the logic in the library subroutine that listens for user requests to move forward and backwards in long lists to reduce the number of user actions needed (less movement of the wrist). In the old code, if you were on the first page of a long list and you requested a page action it would ask you if you wanted to go to the next page. Ditto if you were on the last page of the list, it expected further information. If you were in the middle page of the list you could jump to the prior page or the next page. If you wanted to get to the end of the list you requires several clicks to get there. Now - if you are on the first page and select the page option it will take you to the next page with out asking you for confirmation. If you are on the last page a page request will take you to the prior page with no confirmation required. If you are on any page of the list then you have the options 'first page' 'previous page' 'next page' 'last page'.

As far as I know I have to add component 76 to my plant to be able to use the BCD files. Then, I have to define appropriate control type to read them in. As I can see in exemplar: /tester/test_suite/plt_boundary_conditions/ I have to define control law 12 and the ipsn(?,1) = -1. But that control law has been removed from esp-r and a new sensor is added as ipsn (?,1) = -5. This sensor is intended for reading bcd file. As it is mentioned in esrocom/econtrol.F this sensor is not activated yet. However, I can see the code to read the bcd file with ipsn(?,1) = -5 is defined there but not sure if it is connected to the plant calculation. I have two questions: 1) if instead of control law 12 I have to use ipsn(?,1) =-5 which means define the sensor to read the bcd file what should be the control type and control law. And is sensor = -5 is activated or not? 2) if that sensor is not activated and there is no control law 12 how can I define bcd file for my plant? I really appreciate any help.

GSLedit or WIS is a question of whether you plan to use standard TMCs (then "Window" or "WIS") or CFCs (then GSLedit). The opening schedule you will have to decide for yourself. There is no "given" such schedule. No, the uncertainty item in ESP-r focuses on uncertainties in entry data, however not on schedules / control schemes (as far as I am aware).

My main concern is the behaviour of the glazing while is closed, (mainly the expected overheating of the sunspace), so that?s why I need precise measurements of the glazing/shading system. As you say i'll have to choose ( I need some more exploration). As for the schedule I was thinking to apply the uncertainty, because the manual operation of windows is not clock sharp! I?ll have too use a sensitivity analysis... But I`think I?ll use the uncertainty item apllied to the entry data, mainly the dimensions of the model.

This can be connected to a zonal afn, though Also, a (serious) drawback with obstruction blocks in a CFD-zone is that they do not interact with the air flow thermally, only as flow blockages.

I suggest that you contact the following email address for some clarifications on this facility. Essentially, if the product type is a good match to the underlying representation then you can get good agreement with observations. You can solve the electrical performance as well as the thermal performance of cells taking into account the transient environment around the cells. There is also documentation in the source code. And being an area of interest to a small number of users the facilities do have somewhat of a learning curve. Somewhere I have a document that describes part of the process. Alaa might be able to provide his thesis as well. For other bits of ESP-r learning - look on the ESRU download page for the ESP-r Cookbook it provides lots of info. There are also some video tutorials that I can send links to.

I could imagine that your name is too long (I don't really remember if all the radiance code uses the "default" file name length). That could be your problem (your name length including extension is 32 characters). Further ideas: The .opt-file should be generated automatically. Check the /rad/ directory for any empty or differently named .opt. Try generating the missing .opt manually (use any example file present in the exemplars).

This is probably not related to file name length. Radiance has its origins in Unix environments, so it did not inherit those DOS conventions. However, there is a DEFINE in the sources limiting the length of strings in general. It should be 128 characters in current releases. So you should be far from reaching that limit.

Grobe Sent: 16 February 2012 14:48 To: esp-r at lists.strath.ac.uk Subject: [esp-r] Re: dailight factors+cfd Hi! This is probably not related to file name length. Radiance has its origins in Unix environments, so it did not inherit those DOS conventions. However, there is a DEFINE in the sources limiting the length of strings in general. It should be 128 characters in current releases. So you should be far from reaching that limit. Are you sure that the RAYPATH environment variable is set correctly on your system, and that it includes "." (the current directory)? Cheers, Lars. > maybe check the possible length of file names.

It is computationally efficient (so you can do assessments looking at literally every minute of the year) you can control flow paths (e.g. adjust windows & turn on extract fans). There are also several example models, a chapter in the Cookbook that discusses it and a couple of video tutorials that show the process of planning and creating a flow network. You can learn a lot via flow networks. Later if you want additional resolution then you might explore CFD.

Date: Fri, 24 Feb 2012 09:37:29 +0100 Subject: [esp-r] Re: esp-r - BCVTB Message-ID: We indeed introduced some modifications in the code to establish the connection between ESP-r and BCVTB. A working version of our implementation with all functionality has been committed to our SVN developer's branch: 'ESP-r_BCVTB'. This branch also contains two example models. One example demonstrates a heating controller in Matlab. The other example demonstrates shading control in BCVTB/Ptolemy II, with a possibility for extension to e.g. Radiance. Recently, we also started working on an initial version of a manual/tutorial (note: it is mainly written for 'BCVTB audience'). Here is a link: http://dl.dropbox.com/u/9527295/ESPr_BCVTB_manual_v1.pdf It is our intention to include a tutorial, together with the examples in one of the next releases of BCVTB. Before that, we may need to improve robustness of the implementation. That's why we are looking for your feedback. For more background information, I am also including a link to the slides of our presentation during the ESP-r community meeting at IBPSA bs2011: http://dl.dropbox.com/u/9527295/ESPr_BCVTB_111114.pdf Some remarks: The coupling was only tested on 64-bit unix systems. 32-bit unix may require a different shared library. Please contact us if you need help. Running the examples requires at least basic knowledge of both ESP-r and BCVTB. Setting up new applications requires that you are (or become) familiar with ESP-r's source code.

Or, if they are installed, they have a different name. To check this, a first step would be to issue the command "which g++" on the command line. Also, maybe look in the "bin" directory (wherever "which gcc" or "which gfortran" tells you the binaries reside) and see if you have a similarly named binary, e.g. "g++-4.3" or the like. If yes, you could symlink (see "man ln") the binary to g++. Good luck.

I notice that when I change the reference height of this node, its pressure changes as well. I read in the literature (Clarke,2001 and Hensen Phd Thesis,1991) that the boundary wind induced node pressure is a function of the pressure coefficient set, density, the wind direction and reference wind speed. The reference wind speed is calculated as a function of the free stream wind speed (the one read from the climate file), the height difference and the local terrain roughness. However as I have seen in the flow network menu, the reference wind speed is calculated only if the user assigns a wind profile (power law, logarithmic, LBL). My question is: -If the wind reduction factor is set to '1' should the reference height of the boundary wind induced node affect its pressure?

I exported one of the exambles in ESP-r to see the idea of making the drawing in autocad and I did the same thing using the same idea. I draw the building in auto-cad ( two thermal zones - two layers) and I save it as dxf file to import it to ESP-r but there are some problems with the process I think. I wrote the complete path to the file and still the program did not recognized the location and the file . I asked one of our friends from here and he explained to me some procedures but still I have the same problems. I tried to look in cookbook ad he advised me but still there is no direct steps to do with explanations . What should I do ? In the same way , I opened a new file and in latitude and longitude I put a figures for Saudi arabia which are 20 - 48 , but the note which came that i have to change the longitude to be less than 16 !! Is it depend in the hour deferences ? I need a supervisor to my project from here , I need explanations with photos .. Who will be able to contact with me? I'll be very glad for that.

It would be helpful to say what version of ESP-r you are using and what computer operating system you are using. Some answers below (look for ::) ________________________________________ I draw the building in auto-cad ( two thermal zones - two layers) and I save it as dxf file to import it to ESP-r but there are some problems with the process I think. I wrote the complete path to the file and still the program did not recognized the location and the file . I asked one of our friends from here and he explained to me some procedures but still I have the same problems. I tried to look in cookbook ad he advised me but still there is no direct steps to do with explanations . What should I do ? :: you need to give the full explicit path to the DXF file. It is also a good idea to set the feedback level in the project manager to verbose so that if there are issues when the DXF file is scanned you have a better idea of what the issue is. Many drawing files cannot be read because they are largely composed of block entities rather than 3D polylines. The conversion process from DXF was worked on late in 2011 so make sure you are using a newer version of ESP-r. :: the alternative approach that many people use is to export the CAD as a bitmap image and use the click-on-bitmap approach which is discussed in the ESP-r Cookbook. In the same way , I opened a new file and in latitude and longitude I put a figures for Saudi arabia which are 20 - 48 , but the note which came that i have to change the longitude to be less than 16 !! Is it depend in the hour deferences ? :: longitude in ESP-r is expressed as the degrees from the local time zone. I need a supervisor to my project from here , I need explanations with photos .. Who will be able to contact with me? I'll be very glad for that. :: The ESP-r Cookbook is a good source of information. There are also some short video tutorials that deal with some training issues - links can be sent if you are interested. :: If you intend to do serious research using ESP-r and your PhD is dependent on a good knowledge of ESP-r then would it be possible for you to visit ESRU in Glasgow to make a plan for your work?

If the new technology is to be modeled as a plant component, you will need to add such a component - possibly based on existing components as starting point. This can be quite straightforward, but can also be very complicated. This would definitely entail coding in Fortran. If the new technology can be modeled from available primitive parts, no Fortran coding will be necessary. It may be possible that additional information can allow for a more detailed estimate.

Some background that you might consider... For more than a decade ESRU has welcomed researchers who wish to extend the facilities of ESP-r. Typically we do this by either joint research projects or via researchers visiting ESRU and discussing their work and staff giving a bit of ad-hoc support. Some people even end up doing PhDs here. There is a developers guide which provides some advise on coding standards and there is a development community who often help each other and there is a strong element of testing and code documentation which ensures that new facilities/code does not break existing code and/or models. And, given that ESP-r includes around 2 million lines of code learning to work with it requires considerable commitment. And there is an expectation of a certain level of computer language skills involved. If you are serious then it might be useful to get you and your management/supervisor discussing with others in the development community. And you project might require that you join the development community with your own source code branch. A first step is to clearly describe your goals. It might be that there is already a way to accomplish your goals with little or no coding interventions. ESP-r is a simulation environment in which there are many possible approaches to building and system assessment tasks. Also, your email has a name but no contact information or affiliations. Tell us more about your work and your group/company!

It could save you a lot of time and frustration. What is subversion - its source code control and it is at the core of the continuing evolution of ESP-r. ESP-r is getting close to 8000 revisions. It is the glue that binds the development community together as well as allowing those who are not hard-core geeks keep up to date with ESP-r. Those in the development community might have noticed that I have made rather a lot of commits to the ESP-r repository and have the habit of backing this up with pre-commit syntax checking (forcheck) and lots of runs of the tester.pl scripts. I also compile for multiple compilers and multiple machine types (Linux workstation and compute servers, OSX, Cygwin and Native Windows). I am one of the more paranoid folk in the community. In order to keep somewhat sane I have arrived at some habits which help me balance the paranoid with the pragmatic. Sometimes I have helped others commit their code - and as Joe Clarke has noted this does not scale well. I notice great stuff happening in folks branches that never get into the development_branch. Sometimes I want to get that great stuff so one of my habits is to quickly checkout that other 'branch', compile it and see if that stuff is something that will help me get my work done. Svn allows me to do that checkout with a single command. This workshop is a chance to experience and embed some of these habits. Subversion is like a Japanese tea ceremony - it is a ritual and a habit. Learning it from a book results in a differently tasting cup of tea than if you work with a mentor and get the feel for doing it yourself. I believe that svn saves me LOTS OF TIME and reduces risk. This workshop might just change your level of productivity so that you have more time to do other stuff! Here is the summary from the announcement on the eSim conference web page. I look forward to working with you at the workshop! Regards, Jon Hand ESP-r Source Code Management workshop (afternoon) Software developers working with ESP-r use the source code management tool subversion to update ESP-r, manage their own evolution of code and models as well as communicating their contributions to the development community. Subversion is like a Japanese tea ceremony in its learning curve. For some people it is utterly mind-boggling. Subversion can be a tool that saves you time and protects your work. If you are baffled by the rituals this interactive half-day workshop is your chance to embed new skills and habits. The workshop is hosted by Dr. Jon Hand of the University of Strathclyde in Glasgow who has made thousands of commits and dealt with hundreds of conflicts as an ESP-r developer. If you are in the development community and have been lurking on the sidelines or in a research group and want to increase your productivity or even working with other simulation software and want to introduce subversion into your working practices this workshop has your name on it! During the workshop we will clarify the jargon and review the steps needed for a range of software management tasks. We will also put subversion in the context of tasks used to ensure that the evolution of the software is robust. The schedule is as follows: 13:00-13:45 Introduction SVN and the developer community 13:45-14:15 SVN clients and sandboxes 14:15-14:45 Introduce common tasks (check, merge, commit resolve) 14:45-15:00 Break 15:00-15:30 Experiment with common tasks 15:30-16:00 Review of working practices (good habits and time savers) 16:00-16:30 Testing changes and compile cycle 16:30-17:00 Incorporating revisions into the standard ESP-r distribtuion From jon at esru.strath.ac.uk Mon Apr 23 18:17:37 2012 From: jon at esru.strath.ac.uk (Jon Hand) Date: Mon, 23 Apr 2012 18:17:37 +0100 Subject: [esp-r] There are still places for the air flow network workshop at eSim 2012 Message-ID: <2C3CF455489D6B4F95AFAB84847FA41301BD2E01B7F3@E2K7-MS2.ds.strath.ac.uk> This message is to the simulation community.... In case you did not notice that there is an air flow network design workshop in Halafax next week there is still time to sign up. As with many things in ESP-r working with a mentor in the planning and implementation phases can be an efficient way of embedding new skills. If you really think about it, air movement is an important influence in the majority of simulation projects so use this opportunity to embed well designed flow networks and controls into your models. Go on to the eSim 2012 site and look in the workshops for more information. I look forward to seeing you at eSim! Regards, Jon Hand, ESRU Glasgow Scotland. Below is the announcement on the eSim site..... ESP-r Air Flow Network workshop (morning) Air moves around in buildings - sometimes because we force it and sometimes because we want to encourage natural ventilation. Air is continually moving because of temperature differences and pressure differences and the imperfect nature of architectural and environmental systems details. Although CFD has taken much of the spotlight in recent years, the ability to assess patterns of bulk air movement over tens of thousands of time-steps with very little computational overhead has a place in many research and design projects. As we attempt to design buildings which restrict heat flows through facades even small movements of air begin to play an important role in building performance. Air movement is also tightly coupled to other thermal solution domains and ESP-r has offered very efficient facilities to solve air flow networks simultaneously with the zone and environmental system, transient CFD and electrical power solvers for a number of years. Typical uses are to assess variations in infiltration due to weather variations, assessing mixing between perimeter and core zones, evaluating window opening strategies, CO2 levels and to risk over time. Designing flow networks is an art as well as a science. This half-day workshop will provide an overview of ESP-r flow network facilities, component types as well as models which demonstrate its use in natural and hybrid ventilation studies and research projects. We will plan and implement a network, impose control on it and look at the resulting flow patterns over time. The schedule is as follows: 08:00-08:45 Introduction and tour of models 08:45-09:15 Planning flow networks 09:15-09:45 Exercise to implement a flow network 09:45-10:00 Break 10:00-10:30 Overview of flow components 10:30-11:00 Exercise flow components 11:00-11:30 Exercise flow patterns 11:30-12:00 Closing and detailed questions From Lukas.Swan at dal.ca Tue Apr 24 17:15:18 2012 From: Lukas.Swan at dal.ca (Lukas Swan (Dal)) Date: Tue, 24 Apr 2012 13:15:18 -0300 Subject: [esp-r] FINAL WEEK: 2012 eSim Building Simulation Conference - Register Now!

I know of several people who are using 11.04, but mostly they upgraded from an earlier version. It might be possible that they are using 32bit. 11.04 did alter a number of the underlying libraries and fonts so I have advised many people to revert to 10.10. To be clear - if you compile 64 bit X11 on Ubuntu does the problem also happen? The code that finds and writes the date is not dependant on the graphic library. There are a number of other files in ESP-r models that include date fields. Are they also missing or corrupted? Also, make sure your 'locale' is set so that a period is used as a decimal place rather than a comma. -Jon Hand ________________________________________ From: esp-r-bounces at lists.strath.ac.uk [esp-r-bounces at lists.strath.ac.uk] On Behalf Of ?? ??

Message-ID: <2C3CF455489D6B4F95AFAB84847FA41301BD2E01B817@E2K7-MS2.ds.strath.ac.uk> Hello to the community. This is a - if you must work on Windows with ESP-r you might want to read this message.... - With the great James Weir file a project to update how Windows computers could be configured to compile ESP-r was delayed. As it has been necessary to setup a development environment on several W7 boxes the project has been updated. - The good news is that setting up Msys and MinGW is much simpler than it was in the past and there are new tools available to add required packages needed for ESP-r. The Window GUI based tortoiseSVN now offers a command line subversion so that is brillient as well. - While setting up a W7 box the individual steps were documented and included in the manual/OS/Native_windows folder as a .txt file and a .rtf file. The document has been formatted in sections and the hints have been updated. Several out of date files have been removed. Yes you still need to be a bit of a geek to do ESP-r development work native on a Windows machine. It is in many ways a less satisfying environment than Linux and OSX or Cygwin. If you need it you need it. If you want a copy of the documentation just email me. -Jon Hand From jon at esru.strath.ac.uk Tue May 1 05:11:01 2012 From: jon at esru.strath.ac.uk (Jon Hand) Date: Tue, 1 May 2012 05:11:01 +0100 Subject: [esp-r] looking for some images / models which do something really interesting with ESP-r plant Message-ID: <2C3CF455489D6B4F95AFAB84847FA41301BD2FC5CD41@E2K7-MS2.ds.strath.ac.uk> I am putting together a demo session for ESP-r for the eSim conference in Halifax and I have quite a few topics covered but the images I have for plant are just not exciting, they don't tell much of a story and the networks involved are either simple or ancient.

The Welsh School of Architecture is seeking to appoint a Research Associate to work with the Principal Investigator on a research project funded by EPSRC to develop better outputs from building thermal simulation tools to improve decision making in the design of low energy buildings. ? This research proposes to focus on the gap that exists between the output information from building thermal simulation tools and what is actually needed for building designers to undertake informed design decisions when designing energy-efficient low carbon buildings. It aims to generate procedures to produce post-processed information and data representation systems that are meaningful to building designers ? consonant with their modus operandi and way of thinking. These procedures include parameters, indices, diagrammatic and multimodal ways of representing results as well as possibilities of undertaking design changes. They will be illustrated by a series of tested and validated examples developed through interdisciplinary collaboration with the UK Energy Research Systems Unit (ESRU) and the US National Renewable Energy Laboratory (NREL). ? Applicants should have a good degree in a relevant discipline along with previous experience in conducting and organising research projects in a relevant field. They should have very good knowledge of building thermal physics, evidence of architectural practice skills and excellent knowledge of building design. Good research and analytical skills are essential as are excellent presentation skills. ? This post is fixed-term for 12 months. ? This is a full time position of 35 hours per week. ?

How did you try set it up? Via ProjektManager? Then it may fail because there does not seem to be a default entry in the mscomp.db1. No idea, if there should be / was at some point. So for this path, you have three options, I would think: Try to set up an appropriate input file manually according to examples for other special materials (the basic structure is the same for these, I think) and using the source code as guide line for what is necessary. Or, you could hope somebody on the list has a valid input file and shares. Or, you could hope somebody on the list has an entry for the mscomp.db1 and shares and that the set-up works via ProjectManager after extending the data base.

In-Reply-To: References: Message-ID: <2C3CF455489D6B4F95AFAB84847FA41301BD2FC5CD89@E2K7-MS2.ds.strath.ac.uk> Below you will find a step by step guide for performing a weather file conversion from the EnergyPlus EPW file format to an ESP-r weather file if you are working with the Native Windows version of ESP-r. A similar (but less verbose) description is included in the ESP-r Cookbook (available on the ESRU ESP-r web download site). The instructions work with the most recent version of ESP-r (I can send a link to an installer for this if requested). Regards, Jon Hand Steps needed to convert weather data sets from the EnergyPlus weather site into ESP-r climate files if you are using the Native Windows version of ESP-r. The EnergyPlus weather site includes a .zip file for each weather location. In the zip file are files with endings such as .audit .ddy .epw .info .stat. What we are interested in is the file with the .epw extension. Extract the file with the .epw extension to a known location such as C:/TEMP or C:/Esru/esp-r/climate. Users of ESP-r on other computer types have command line options for converting weather files but for the Native Windows version you should just start the ESP-r weather module clm (it is located in the C:/Esru/esp-r/bin or C:/Esru/esp-r/bin_graphic folder). When the clm module starts it presents a list of the weather locations it already knows about. At the bottom of the list is an option '* new climate db' choose this and use the file browser to change the folder (see below) and then type in the name of the new ESP-r weather file to be created e.g. USA-Cali-Alfonso. Your choice of folder for the new weather file might be C:/Esru/esp-r/climate (where all the other ESP-r climate files are located) or you might want to choose the dbs folder of an ESP-r model that will be referencing the weather file. The clm module will present a menu titled Weather Analysis and the option (k) provides acess to a facility to import weather data from a text file (the .epw file). Choose option k and then confirm that it is an EPW weather file that you wish to import. User the file browser to locate the .epw file that you downloaded and saved. After a few seconds the Weather Analysis menu will re-display. There will likely be an EOF sensed warning in the lower dialog. This is expected as the end-of-file .epw file was reached. Now check that the climate data has been correctly scanned. Use the option 'd graphic analysis' option and look at the whole year. One at a time plot the climate data to check that the values are ok. If the data looks good then you have a correct ESP-r weather file. This file is actually in a binary format that the simulator module of ESP-r can read but which may not be readable on other computers. Before leaving the clm module you should create an ASCII version of the ESP-r weather file. Choose option 'j export to text file' and confirm that it is to be an ASCII esp-r file. It will suggest a file name (ending with .a) in the same folder as the binary ESP-r file. The ASCII version can be sent to other people and converted for use on other computer operating systems. ________________________________________ From: esp-r-bounces at lists.strath.ac.uk [esp-r-bounces at lists.strath.ac.uk] On Behalf Of alvastel alvastel [alvastel at gmail.com] Sent: 14 May 2012 23:12 To: esp-r at lists.strath.ac.uk Subject: [esp-r] How work with .WEA files in ESP-r?

If a simulation has just been run and there is more memory available than the size of the results file then the scanning task will use the data in the memory buffer rather than going to disk. I have worked with results files ~2GB with a machine with 3GB of memory and the pre-scan might take 5 minutes but if it the results file was from an earlier session the time grew. I have code that detects likely long pre-scans and skips the pre-scan but that has yet to get into the development_branch. For now the easiest fix is to ensure that you have a significant block of free memory when you start simulation / results recovery tasks. -Jon Hand ________________________________________ From: esp-r-bounces at lists.strath.ac.uk [esp-r-bounces at lists.strath.ac.uk] On Behalf Of Achim Geissler [achim.geissler at intergga.ch] Sent: 23 May 2012 20:54 To: Justin DeBlois Cc: esp-r at lists.strath.ac.uk Subject: [esp-r] Re: Results Module, pre-scanning results databases Dear Justin sadly, this is normal behavior for res.

The WARNING message is about a blank file name for the file that holds the zone simulation results. If the model is plant only this is not an issue, if the model includes zones and plant then this file name should be provided. The 'problem with configuration line 0' I would like to see the model configuration (.cfg) file. We would need to look at your model to determine if there was an error in the description of the model. One thing to check - ESP-r requires that the localle of the computer be set to a location that treats the decimal place in a number as a dot rather than a comma. For example a UK or USA localle will work while a French or Japan localle typically does not work and will quickly corrupt models. There might be a problem with some of the plant exemplar models - tell us the specific name of the exemplar model that you tried to work. -Jon Hand ________________________________________ From: esp-r-bounces at lists.strath.ac.uk [esp-r-bounces at lists.strath.ac.uk] On Behalf Of wakana-m at ec.hokudai.ac.jp [wakana-m at ec.hokudai.ac.jp] Sent: 19 June 2012 04:46 To: esp-r at lists.strath.ac.uk Subject: [esp-r] Plant Exemplar Dear all, Hello.

Also, you will probably want to have more than one zone in the width (ideally in the depth, as well, to allow for different directions of flow along the inner and outer skin of the facade cavity. If the corners of the building are also open, as it seems to be, it may be interesting to really have a set of zones enveloping a central "building". The standard maximum number of zone is 82, so this may be a limit. For the stack, you could split the height of the building into maybe 4 to 10 segments, for the width per fa?ade 2 segments. This would give you 32 to 80 zones (so 10 in the stack would already be close to the limit) without a split in the depth. With a split in the depth, a stack of 4 would lead to a total of 64 zones. The actual building could be "a few zones", however, then be aware that the detail of results is also very limited and you will need to add appropriate thermal mass and internal loads. If you expect cross-flow and "around the corner flow" in the fa?ade cavity to be negligible, of course looking at one fa?ade elevation only would greatly reduce the number of zones or allow for higher detailing of zones. You could turn the model via script for calculations in all directions. The "best" approach will strongly depend on the most important issues to be studied.

From intuition it could be argued that a double fa?ade cavity will get warmer than the outside - or at best the same as ambient - therefore adding to the building loads. Perhaps this is more a winter driven strategy? Again with good glazing you probably get rid of most heating loads in such climate. Then again you never know, that's why we go to the trouble of modelling these things. I would be interested in the key headlines of the outcome if possible?

Can you describe the design idea which supports a double skin on the North face of the building? Is it the same kind of facade as on the South face? Consider that the timings of the solar exposure on each of the facades is radically different. A North double skin might have much different economics to the other facades, it might have rather different characteristics and the building might work better without the North skin. It requires only a few changes in the source code to move from 82 zones to something like 99 zones (lets avoid going to 3 digits in the zone numbering because some of the reporting and file I/O might assume only 2 digits. A cautious approach would be to model a portion of the building and the facade so that you can learn quickly about how zone descriptions and flow networks are designed and can test and learn prior to scaling up the model. To get a 4-6 level model working kills fewer brain cells than attempting a seriously complex model. -Jon Hand ________________________________________ From: esp-r-bounces at lists.strath.ac.uk [mailto:esp-r-bounces at lists.strath.ac.uk] On Behalf Of Geissler Achim Sent: 21 June 2012 10:58 To: esp-r at lists.strath.ac.uk Subject: [esp-r] Re: Suggestions for Double Facade Modeling Dear ?mer basically, you will want to model the facade cavity as a set of stacked zones.

The actual building could be "a few zones", however, then be aware that the detail of results is also very limited and you will need to add appropriate thermal mass and internal loads. If you expect cross-flow and "around the corner flow" in the fa?ade cavity to be negligible, of course looking at one fa?ade elevation only would greatly reduce the number of zones or allow for higher detailing of zones. You could turn the model via script for calculations in all directions. The "best" approach will strongly depend on the most important issues to be studied.

Juni 2012 22:05 An: esp-r at lists.strath.ac.uk Betreff: [esp-r] Suggestions for Double Facade Modeling Dear esp-r Users, We would like to simulate a 43 storey high office building (located in a Mediterrenean climate) with double facade for energy calculation purposes. The double facade is a single cavity on all four sides of the building and from first floor to the top floor. The depth of the cavity ranges between 3 - 5 meters. The design intent is to ventilate it via thermal buoyancy and also operable windows on the exterior skin (automatic control). No natural ventilation of the office interiors or night time cooling is foreseen at the moment. We would like to analyse the best ways of design and operation and see how much we can decrease the HVAC cooling / heating running costs. We intend to use esp-r and DOE/eQuest for this. I would appreciate any suggestions on how to approach this task. Thank you, ?mer Moltay, LEED AP BD+C, ASHRAE BEMP, CPMP, BREEAM Assessor Mimta EkoYapi Hekimsuyu Cad. 559. Sk.

The obstructions do not have a temperature, so, calculation of long wave radiation exchange with an external surface is not possible. The material one can attribute to the obstructions is used only for export to Radiance, as far as I am aware. External long wave radiation is split according to the settings in "sky, ground, surrounding". Sadly, I think, these settings can be set only once, i.e., they are valid for all (external) elevations of a model.

The approach is to model the panel as a (thin) zone bounded by the metal of the panel and with high internal heat transfer coefficients. You then inject or extract heat from the zone (run the simulation at a short timestep). This is a good representation of the radiant and convective transfer with the room. It does not give you information about the fluid temperature in a real system. An example for a radiant heating model is in the folder training/rad_room_heat. There is a notes_rad_rooms.txt that explains the approach. -Jon Hand ________________________________________ From: esp-r-bounces at lists.strath.ac.uk [esp-r-bounces at lists.strath.ac.uk] On Behalf Of wakana-m at ec.hokudai.ac.jp [wakana-m at ec.hokudai.ac.jp] Sent: 05 June 2012 10:18 To: esp-r at lists.strath.ac.uk Subject: [esp-r] ceiling radiation cooling system Dear all, Hello.

Normal users should not use the CEN 13791 because it forces the same direct solar radiation on both sides of a partition. This could only be true if you live in a universe with two suns. In our universe there is only one sun and thus direct solar radiation would find it difficult to strike both sides of a partition wall.

I ended up installing CAElinux as a dual boot option on my notebook, and using Salome-Meca, an open source product that has an FEA solver competitive with the higher end commercial programs along with a decent GUI base pre/post processor. I have used esp-r for performing simulations on my own home. I have not used it for commercial or research purposes. So I have some but not extensive knowledge of the program, but have followed the comments on this list. The comments from a few years ago regarding the long term development of esp-r leads to this posting. Salome is a geometry creator and incorporates meshing tools. It contains all the primitives of points, lines wires, faces, shells and solids. A building, or a room could be considered a shell. For the purposes of FEA or CFD computations, the program has a built in interface to meshers, and can also accept commercial meshers. It is interfaced with Code-Aster to perform the FEA calculations. Finally it will post-process the results. The interface is a modern look and feel graphical user interface. All the commands that are used to build a geometrical structure are saved as a python script. Salome can dump the python script, which can be edited and then loaded again, for recalculation. Code-Aster, the FEA portion of the program, is actually a number of Fortran or C coded modules that are strung together in a python script. This makes the program extremely modular, and one area can be changed without affecting any of the other modules. Python stores the information output from each module for the next module to use. I have not used Code-Saturne (CFD program), but from what I can determine it uses python scripting similar to Code-Aster to control it. Then there is another program called SYTHRES, about which I don't know much. The programs are all open source, and are also compatible with a number of other open source programs such as GMSH, for geometry and mesh creation and Paraview, a well developed US government open post-processor. The FEA and CFD portions are actively developed by EDF the research arm of the French nuclear industry. I believe Salome, the pre/post processor is also supported partially by the EDF team. There are both similarities and differences in the CFD/FEA world, compared to building envelope/plant simulation world. Both require geometry input and post processing. esp-r uses results from FEA analysis to give more accurate foundation heat loss results. esp-r has a simple CFD module. Based on the comments from a few years ago, where there seemed to be interest in modernizing the programming and development environment of esp-r, and then learning about the above open source programs, it seemed that there might be synergy. I expect it would require looking at the core computational engine of esp-r, breaking it out into individual blocks, and have each block called by a python script. The current esp-r user interface can be maintained and/or ways sought to make Salome or other open source software work well for the pre-processing (building geometrical layout) stage. In this environment there would be options to use highly developed CFD and FEA code, chained together with building simulation code, to perform analysis that includes airflow in rooms and 3D heat transfer between the building or plant elements and the ground. I thought I would throw the concept out to see if there is any interest in discussing a building simulation program that is run from within a python script, and the flexiblity that it would allow, in a manner that would leverage existing open source tools to provide options in the CFD/FEA domains.

I have a problem about the importing the .DXF to Esp-r. I have read all the mails related to this topic in our archive and the DXF I am using is exported from a current model from Esp-r. After I created a new model in project manager .under "import & export" , import CAD file, choose DXF (version 12). Esp-r asks "proceed with CAD package(no will just generate this file)", press "yes", while at the same time an indication is given" task terminated with an error condition",but you are still asked "import the CAD transfer file" ,press "yes". "File to import" ,just give the full path of the .DXF , for example"C:\Esru\Models\test\office.dxf". After that Esp-r asks me to specify the system configuration file,I choose " office.cfg". Esp-r tells me that "problem with configuration line:translation from Autocad", in the end it says "while reading the model configuration file a problem was detected . try again?" but if tried another time, "problem with configuration line:translation from Autocad" showed another time... Did I make some mistake? I am using Winows XP. the revision of Esp-r is the one available in the official website now. Thanks.

I cannot find any guidance for this problem anywhere (cookbook, tutorials, exemplar models, etc) so my last hope is you guys. First, the basics: OS: 64-bit CentOS 5.8 ESP-r: "Release branch" Release 11.11, revision 8518, compiled with GNU compilers (have tried with both X11 and GTK graphics libraries) Now, the problem: I am trying to use type 2 thermal conflation (i.e. get point air temps from CFD). I have worked out the input procedure without a problem, can run type 1 thermal conflation without a problem, and get results. The problem arrises when i try to get results from a type 2 thermally conflated analysis. To minimize confusion I'll go through it step by step: * I select "CFD" from the res module main menu, point it to the CFD library, and it reads it in without a problem. * I create a view; first I input a name and a direction, then it asks "Which X layer". At this point, if i put in any integer above 1 (say 5 as an example), it says: "The input value for ' Slice number' (5) should be less than 0! Please re-enter." * So i try an integer less than 0 (say -2) and it says: "The input value for ' Slice number' (-2) should be greater than 1! Please re-enter." * I have tried 1 and 0, and they just result in the same error messages respectively. Decimals just result in the text input box resetting. * The ONLY way past this step i have found is to press "use default", in which case it uses 1 but somehow accepts it. * After selecting a resolution the view is created, and appears in the interface. * When i now select "create image(s)", it does not work, no matter what image format i use. On-screen graphs ("screen2d" option) are blank, TEC and paraview files are blank, bitmaps are corrupted, and XPM just crashes the program and throws up a shell msg "Segmentation fault". Is there any other way that i can get local air temperature results from the CFD? I've tried timestep reports but with type 2 thermal conflation all the temperatures are NaN. This has been holding me up for weeks, if anyone can help in any way id be greatly appreciative.

The NAN is not related to the interface choices - that is in the solution but I could imagine that the reporting has no idea how to plot NANs. Compiling with the extra debug option might allow it to identify numerical glitches. There should be a simulation trace function in the simulator which, like other trace functions will write out intermediate calculation information as the simulation progresses. I have not used that but it might give some valuable clues. One alternative, if you have access to a 32 bit Linux is to try and run it on that to see if the reporting works better. Also - a number of changs were made a few weeks ago to the development_branch be sure to issue an svn update command to ensure that your source is up to date. -Jon Hand ________________________________________ From: esp-r-bounces at lists.strath.ac.uk [esp-r-bounces at lists.strath.ac.uk] On Behalf Of Andrew Cowie [cn06arc at leeds.ac.uk] Sent: 28 August 2012 18:36 To: esp-r at lists.strath.ac.uk Subject: [esp-r] CFD problem - cannot get results Hi all, I''ve recently delved into the convoluted realm of CFD within ESP-r, and am having terrible trouble coaxing results from it.

Newbies (and PhD students) on this list might consider - Learning often involves hitting your head against the wall. Hitting your head a 2nd time also happens and it is natures way of telling you that NOW would be a good time to talk to other people (even your supervisor). Hitting your head a 3rd time is << fill in your own *!%! >>. Someone else might recognize the issue and have already know a work-around. And you might not get an answer or it might take a while... And there is quite a bit of knowledge in the community....so give it a try. And to embed that knowledge - especially on topics such as CFD if this model proves to be working well and is understandable consider contributing it for inclusion as a well-documented exemplar. -Jon Hand ________________________________________ From: esp-r-bounces at lists.strath.ac.uk [esp-r-bounces at lists.strath.ac.uk] On Behalf Of Andrew Cowie [cn06arc at leeds.ac.uk] Sent: 30 August 2012 14:59 To: esp-r at lists.strath.ac.uk Subject: [esp-r] Re: CFD problem - cannot get results SOLVED Hi all, Problem solved.

It introduces a version number, date stamp, categories with documentation, documentation for individual constructions and a tag data format which should be easier to parse. The format allows the names of MLC to be phrases up to 32 characters with documentation up to ~248 character (the remainder of the line). It also allows for the optical properties name and pointers to 'reversed' MLC to be up to 32 characters. As with the materials categories, categories can have one to one-less-than-the-max-number-of-items. In a direct translation from current MLC files the names will and attributes will be 12 characters. New entries or conversions after editing would support longer names but would not be usable with older versions of ESP-r. Commas are used to separate tokens which are potentially phrases with spaces. If you look in the examples below I have been trying a comma-single-space separator which is a bit more human readable than a pure comma separated list of tokens. Otherwise spaces are used for separation. The newer format zone geometry file is able to handle phrases for constructions names and optical names and the zone constructions file should require little or no alteration to use construction names phrases. There might be further attributes which would be useful to include in the MLC file. One could be to add an *outer and an *inner line of attributes for each item which could hold the solar and visual and perhaps colour (rgb) attributes at the outer and inner face. These would be instantiated via a scan of the materials. Such entities would remove the need for scanning materials properties and RGB values would allow for exporting Radiance models which could be colour rather than just grey-scale. To support acoustic analysis one would need names for acoustic properties for the overall construction as well as each layer. These could be fitted into the scheme. Comments please....

Naming constraints is one of them so I really enjoy the idea of phrase naming. I have a few points to suggest about the rest of the format: [Disclaimer: I have not evaluated the consequences of my suggestions in terms of code change requirements, yet. They are just wishes from a user point of view.] - If wee choose comas as a field separator for names, what about sticking with it and use it for every fields? Using the quite common "leading and trailing blanks strip" would allow users to arrange the file as columns if they wish. Last but not least I guess it could make the parser simpler. - Now that wee have opening and closing tags for the class (*class, *endclass), wee do not need to put the number of items anymore. It is kind of a redundance with the item tags in between. - I like your idea of giving *outer and *inner attributes for passing to Radiance. What about giving a Radiance "modifier" instead of RGB values? It would allow any color/pattern/texture/... available for Radiance to be used by the MLC database. I have two questions, though: 1) What is the "1 # number of classifications" for? I guess the "*end" is related but I do not see the point. 2) Is there still a need for class indices? If names (phrase names?) are enough to sort items out and write the file, removing class indices would make it coherent with the new MLC way. I hope those comments will help. Best regards, Olivier Bounhoure PS : feedback about my English will be wellcome, too :) The modifications I suggest from Jon's file: --- *Constructions, 2 *date, Sat Jun 23 12:15:16 2012 # construction defined in ./multicon.dba # based on materials ./material.db3.a *doc, ESP-r MLC Constructions including required materials for UK code complience.

As always, basic info first: OS: 64-bit CentOS 5.8 ESP-r: "Release branch" Release 11.11, revision 8518, compiled with GNU compilers The problem: When running CFD sims (type 4 conflation, handshaking type does not appear to affect the problem), some of the time the CFD calcs will seemingly stop at some random point. All of the CFD results (from the monitoring file) from this point on are NaN. This causes the sim that it is currently on to prematurely "converge", and all further sims "converge" in 20 iterations (coincidentally, for those who remember my previous CFD problem, this is exactly what would happen when i ran type 2 thermal conflation, except it would do it all the way through every time). I have found a number of clues to the problem, but i can't seem to pin it down: * In the CFD monitoring file, the NaN's always start at the W value, i.e. the entry will always be: XXXX YYYY ZZZZ NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN where XXXX is the iteration where the error occured, YYYY and ZZZZ are correct as far as i can tell. * In the ACC actions file, in all sims after the error has occured (it will always occur in the actual simulation, not the preliminary CFD), when the ACC algorithms are invoked all FORorNAT numbers come out to be 0. However the handshaking calcs appear to be fine. * I have ran it in gdb with the debugging markers, and it did not come up with any errors, so no obvious numerical issues. * The errors will occur consistently in the same place for the same sim. Thats it, i havn't found any other patterns to the errors. As far as i can tell though it is a tad more likely to happen the warmer the climate in the sim. Also, it only seems to happen for models with windows. Any ideas? As i'm sure you can tell, im not the worlds best debugger so any input at all would probably be helpful.

I added *docclass tag for the line of documentation for construction classes and *docitem for the line of documentation for each construction. This is a bit more readable. The edited example file is shown below. The initial phase of freeing the code from the FIXED format for the construction attributes (name, optical properties, link to reversed construction) is essentially complete and the code now works by scanning the construction attributes into separate variables for each attribute and then the code uses these arrays rather than working with the DESC array (which required decoding at each instance as well as local variables). Having moved away from the fixed formating we are free now to look at the code blocks which have only been interested in the initial 12 characters (single word) construction attributes and generalize them to work with longer phrases. For now, the names of optical properties will remain at 12 characters and when that file format becomes the focus of attention we can loosen up that attribute constraint.

The problem as described in my previous post occurs because the variable RESORW in CALCW is becoming NaN. I've traced the NaN's back to BNDARTT in the file bndaryt.F; they first occur in the variable Uqstor(2,3,7). The root of this is because Tq is calculated as 0 in the loop (8722 i think) where Uq is calculated. The problem is the array Tf, but for some bizarre reason gdb doesn't recognize it as an array, it thinks it is a scalar of value 15.5. So this is my impass; i can't debug this in the code because it wont compile if i test Tf as a scalar, and i can't debug it in gdb becuase it won't recognize it as an array and hence i can't inspect the specific value Tf(2,3,7). I have tried compiling with extra debug options, and nothing is being flagged until the NaN's start cropping up, which obviously isn't helpful. Any ideas/comments/input-of-any-kind would be gratefully recieved, i have to present my work in a week and it's not gonna look good if i have to make "it doesnt work" last 20 mins.

Have you tried adding some write(*,*) lines e.g. for the Tf(x,y,z)? In addition to other variables that may be involved? This is tedious, but often helps get an idea what may be going wrong (and there should be no "scalar vs array" problem).

Looking at the code shows that in some places the variables are explicitly typed, in others not (same Commons). This may be a problem, but not really that likely. If you have crawled through the code so far, already, looking for possible places where a "divide by zero" could happen would be my next thought. I don't recall what the original difference between your working model and the not working one was. With your new insights, does this difference maybe point to a specific place in the code?

All i did was rename the "Tf" array "Tfb" and hey presto, problem solved. No Tq evaluated to 0, no NaNs, everything appears to be working fine. I've checked and there is no other Tfb anywhere in ESP-r, so should avoid further clashes. It's probably worth mentioning though that once i did this the behaviour of the CFD changed considerably; i can only conclude that this name clash was affecting the CFD whether or not it caused an error. After my presentation and once i've worked out how to use my developers account i'll upload my debugged version, but if someone else wants to take care of it sooner be my guest, it's not a difficult fix.

This should cause a compile time error. 2) I always found gdb a pain for printing values in an array. I suggest adding an if statement so that only the cell you are interested in prints out (unless you want to manage a massive text file) 3) I've had a look in the code and if I'm looking in the correct place I see the following. The wall and air temperature are the same => Tq=0, qflux=0 and then Uq=0. There is then an term calculated in an if statement that has Uq on the denominator - this will produce a NaN if Uq=0. (Andrew I'll send you a file with a potential fix).

I've traced the NaN's back to BNDARTT in the file bndaryt.F; they first occur in the variable Uqstor(2,3,7).

This is currently not covered in the ESP-r Cookbook. There is another tutorial which describes most of the process of setting up BIPV (I need to locate the file and can upload details when it is located). There are some exemplar models which include explicit electrical characteristics and an electrical network along with the usual ESP-r descriptions. A review of those exemplars would increase your knowledge of the topic. The electrical facilities use concepts and jargon familiar to electrical engineers and is aimed at performance issues at time-steps greater than 1 second. Wind turbines are usually represented outside of ESP-r.. You might what to have a look at MERIT or ENTRAK (both on the ESRU web site) for demand and supply matching. Perhaps others in the community will have additional suggestions about representing wind turbines.

As i understand it this is not "best practice" for ESP-r, but it works for me. Be careful though as some text editors will corrupt the ESP-r data files. I think there is some info on this somewhere in the cookbook or other documentation that is included with ESP-r, sorry i can't be more specific.

The parameters of the control are listed in the file cellular_vav.contents within that model's doc folder. If you want to see more of the logic associated with the solution of this control look in esrubld/bcfunc.F in the subroutine BCL22. According to the code the normal information written into the building results file does not include the flow rate used, however if you activate the 'trace' facility for controls in the simulator prior to running the assessment the underlying performance attributes will be dumped into a separate file named fort.33.

There are minor differences between the classic X11 interface which runs on all platforms except native Windows, and the alternative GTK-based interface. The interface has evolved more quickly than the Cookbook so the match is not exact. The Cookbook discusses methodology and strategies and model quality assurance. It does not cover numerical methods - for that you should look for Prof Joe Clarke's book. If you downloaded the native windows version from the download site be aware that there is a newer version which I can send a link for. The chapter on detailed systems does provide background on how to plan and describe HVAC systems within a model. The discussion could be improved. We are working to add better example models. Creating explicit systems requires attention to detail. The Cookbook does not describe how to incorporate PCM into a building envelope. I attach a link to a PDF from 2009 which describes the process.

If you have defined the fan as part of an air flow network then what you need to do is to create an entry in the model control file for the branch of the flow network associated with the fan component. Sense the temperature of the air flow node in the room you are interested in and actuate the fan or volume flow component. There are a number of control laws available for such components ON/OFF, PI, range-based controls. There are examples of imposing control on flow components within the training folder of ESP-r. The ESP-r Cookbook discusses the design and implementation and control of air flow networks. If you define the fan as part of a component based plant network then you would define a control law and sensor and actuator within that domain. And there is an abstract approach that you can use to impose changes in scheduled air infiltration as part of a zone operation file. It could be as simple as altering the default assumption about infiltration rates to a different value if the room temperature or the outside temperature was greater than a specific temperature.

One of the great things about ESP-r is that there is usually more than one approach that can be used depending on the kind of information you have and the performance data that you are curious about. I attach a link to a quick model I created which explores each of the common variants in one model (so you can compare them easily). Note that the model is work-in-progress. I used it to explore a heat exchanger plant component as well as a simple reduce-infiltraton method and an zone-based explicit representation of a heat exchanger. It was generated on a Linux computer and might need a few tweaks to work on other platforms. It was also created with a rather new version of ESP-r and might crash if used with ancient versions of ESP-r.

If you open the exported file in a text editor while the results analysis module is still running there is a chance that the operating system has not finished writing the contents of the file. What some people have done in the past is (in the results analysis application) to toggle the re-direct of output from the file back to the text feedback of the application and then ONE of the following: a) exit the results analysis module b) asked to export data to a new export file with a different name. One of these should force the data still in the buffer to be written to the export file and then close the export file so that it can be used by other applications. If you are working with the Native Windows version of ESP-r it might be that you are using an older version and you might also try to update ESP-r. I can send a link to a new installer if you wish.

So, the modeling could be along the simple lines of adding the water tank as a zone, filling it with water (instead of air) and somehow connect this to whatever "conditioning system" is planned on being used (I would expect the temperature of the water in the tank can be somehow influenced?). Although in terms of "heat storage" the "no insulation" concept is entirely unclear to me. What kind of climate zone are you considering?

Note, however, that the constructions database should use only materials defined in the materials database of the model. Otherwise it will not work. In regard to the PCM, as written yesterday (PM), the only "correlation" you have are the entries in the .spm or .spf or whatever file generated for special materials. Here, you will find the line which gives you zone, surface and layer (node) to which the PCM properties are alloted (see the example file I sent).

Sorry, I don't know. I haven't looked at the "other face" thing in a while. Isn't "other face" the one facing outside of the zone under consideration? The value will depend on what boundary condition you defined. If you defined "similar" for internal walls, then "other face" will have the same values as "inside face". > 2.I preset the absorbitivity 15% for the glazing in optical database, for each surface, should the "SW rad abs( other fc)"/global irradiance of this surface =15%?but it is only around 4%.The transmissivity is 10%.Why? Careful with "global irradiance". What are you using, here? You should look at the radiation hitting the surface, not global (possibly horizontal?) radiation. > 3.I tried to set the absorbability 99% for the grazing in optical database, for each surface, "SW rad abs( other fc)"/global irradiance of this surface=25%? Strange values for a glazing. Typical values would be (double glazing unit) trans=60 - 70%, abs=8-15% refl=1-abs-trans > 4. Where I can get the absorbed solar energy by floor? For any given surface, I find it easiest to add a small surface with an opaque material I called "sensor". This is totally black (absorption = 0.999). Thus, "solar absorbed" on this "sensor surface" is the amount that hits the surface (everything is absorbed). > > Regards, > > Hua > > > From: achim.geissler at intergga.ch > Date: Sat, 20 Oct 2012 19:38:49 +0200 > To: surano1505 at hotmail.com > CC: esp-r at lists.strath.ac.uk > Subject: [esp-r] Re: solar problem > > Dear Suo Hua > > see some comments / answers below, inline. > > Best > Achim > > On Oct 19, 2012, at 12:03 AM, HUA SUO wrote: > > Hello, ESP-r experts. > > I made a model that the all the fa?ade is totally single grazing( material newly created by me) and the floor is opaque.

How large is the space? Be aware, that "SW entering" and "SW (other fc)" will likely include diffuse radiation from all four wall surfaces, so tracking the exact numbers in such an example may be quite tedious. Your write you get the "global irradiance" by the "other face" value when you " set all each glazing surface to be opaque ". I suppose you mean when you set the absorption to 0.99? Do you set all four walls to the same at the same time? To check the above (additional radiation entering and of course being reflected out again through the "other three walls"), have you tried having only one transparent wall? Also, do get an idea of what is happening on the floor, maybe split this up into a set of surfaces, so you can see where the direct hits are and where only diffuse radiation is hitting the floor. I am not quite sure what your goal is, though. Best Achim Von: HUA SUO [mailto:surano1505 at hotmail.com] Gesendet: Sonntag, 21.

Could you also help me with the following questions? 1.why the output for each surface , "SW radiation(inside)" equals to "SW rad abs(other fc)", except that the information in the floor does not exit in "SW rad abs(other fc)" ? Sorry, I don't know. I haven't looked at the "other face" thing in a while. Isn't "other face" the one facing outside of the zone under consideration? The value will depend on what boundary condition you defined. If you defined "similar" for internal walls, then "other face" will have the same values as "inside face". The boundary conditoin is exterior for each surface, I do not have internal walls in the model. 2.I preset the absorbitivity 15% for the glazing in optical database, for each surface, should the "SW rad abs( other fc)"/global irradiance of this surface =15%?but it is only around 4%.The transmissivity is 10%.Why? Careful with "global irradiance". What are you using, here? You should look at the radiation hitting the surface, not global (possibly horizontal?) radiation. I got the "global irradiance" when I set all each glazing surface to be opaque, extracted from "SW rad incid(other fc)".It should be the correct one. 3.I tried to set the absorbability 99% for the grazing in optical database, for each surface, "SW rad abs( other fc)"/global irradiance of this surface=25%? Strange values for a glazing. Typical values would be (double glazing unit) trans=60 - 70%, abs=8-15% refl=1-abs-trans It is a test I did for understanding the output. When I set the absorbability 99%, I expected for each surface"SW rad abs( other fc)"/global irradiance of this surface=99%, but it turned out to be 25%...I also tried some other number , also disapponting result in the end. 4. Where I can get the absorbed solar energy by floor? For any given surface, I find it easiest to add a small surface with an opaque material I called "sensor". This is totally black (absorption = 0.999). Thus, "solar absorbed" on this "sensor surface" is the amount that hits the surface (everything is absorbed). In my case as the floor is in contact with the indoor air, is the output of "SW radiation(inside)" for floor the total solar hitting on the it ?But how can I get from the result analysis the amount of the solar energy absorbed?

I made a model that the all the fa?ade is totally single grazing( material newly created by me) and the floor is opaque. After several test , I have some questions and hope that I can get help from you. 1. I found that if I change the properties in the material database for the single grazing, namely " the solar direct tran" , "solar reflec out", "solar reflect in", nothing changes for the simulation result. Only if I change properties in the optical database ,namely"direct trn" "reflct" "abs" that can affect the simulation result. Am I right? Yes, the properties "trans" and "abs" ("refl") for transparent materials are taken from the optics database. The property "eps" (long wave emissivity), the geometry (i.e. the layer dimensions) and the thermal properties (thermal capacity and thermal conductivity) are taken from the materials database entry. 2. For the RES file, "solar entering the zone" is the summation of transmissivity (the parameter in optical database) multiplies the global irradiance for each glazing surface. What is "solar absorbed in zone" ? I checked that it is not the summation of absorptivity (the parameter in optical database) multiplies the global irraiance for each glazing. It also can be noticed that " solar absorbed in zone" is less than "solar entering the zone" in all the test I did. "solar absorbed" is that part of entering solar radiation that is not re-reflected directly back out of the zone. 3. When I try to get the solar energy that passes through the glazing and then absorbed by the floor , I extracted the information from " SW radiation(inside)" , it seems that this parameter is very large and obviously not equal to the absorptivity of the floor multiplies the global irradiance to the floor(how to get this parameter ?). And for the glazing "SW radiation(inside)" divided by the irradiance is not the absorptivity I gave .What is "SW radiation(inside)" means exactly? Are you writing out the values "per m2"? SW (short wave) radiation inside should be closely correlated to radiation hitting the given surface and transmission of the transparent material (not absorption).

Did you add a flow network? If yes, and if the ventilation is to be "natural", then you will likely want to control an opening? E.g. open or close a window? There are several possible approaches to this. If you really do want to have "hourly" changes (when using an air flow network, time steps of an hour may lead to problems), the best approach may be using a TDF file. The alternative is to set up a standard "air flow network control" via ProjectManager. This is a very similar procedure to setting up (thermal) zone control.

The ON/OFF control will test a condition and decide whether flow is applicable at that timestep. It then multiplies the nominal capacity of the component by the fraction-of-capacity applicable at that timestep to get the flow rate to use. Thus - a fraction capacity of zero should result in zero flow for ON as well as OFF state. I would expect you to use a fraction-of-capacity of 1.0 if you want the ON condition to result in the nominal flow rate. If the fraction-of-capacity was 0.5 then an ON state should result in half the nominal flow rate of the component. This is what is used with constant volume flow components. It should also apply to constant mass flow components. -Jon Hand ________________________________________ From: esp-r-bounces at lists.strath.ac.uk [esp-r-bounces at lists.strath.ac.uk] On Behalf Of wakana-m at ec.hokudai.ac.jp [wakana-m at ec.hokudai.ac.jp] Sent: 31 October 2012 05:17 To: esp-r at lists.strath.ac.uk Subject: [esp-r] Re: Control of air volume Dear Jon and everyone, Thank you for your prompt response.

I have calculated the natural room temperature using night ventilation. The size of a model is shown below. Height : 3m Width : 4m Depth : 5m The air change rate of this model is 0.5 ac/h. The south window area used for ventilation is 3.5 m2 and the north window area is 1 m 2. I attach the elevational view and sectional view of a model which were used for calculation. I calculated in the following procedures. (1) I considered a three kinds model. A) The model which has not set up night ventilation. B) The model which set up night ventilation. C) The model which not be used it , although night ventilation was set up. I set up in the following procedures about B) and C). (1) I chose network flow (menu) and defined Nodes, Components, and Connections. And Link nodes and zones was chosen. (2) I chose network flow from Controls. sensor details chose dry bulb temparature and flow actuator chose single flow connection. (3) I chose 1 day type by period data, and it defined B as follows. This my definition assumed that outdoor air temperature opened a window at 18 to 27 degrees at night. a 1 0.00 outside ambient > low /default/mid/hi 18.00 22.00 27.00 0.00 1.00 0.00 b 2 6.00 outside ambient > low /default/mid/hi 18.00 22.00 27.00 0.00 0.00 0.00 c 3 22.00 outside ambient > low /default/mid/hi 18.00 22.00 27.00 0.00 1.00 0.00 The definition of C) is shown below. a 1 0.00 outside ambient > low /default/mid/hi 18.00 22.00 27.00 0.00 0.00 0.00 b 2 6.00 outside ambient > low /default/mid/hi 18.00 22.00 27.00 0.00 0.00 0.00 c 3 22.00 outside ambient > low /default/mid/hi 18.00 22.00 27.00 0.00 0.00 0.00 (4) Annual natural room temperature was calculated. ( esp-r 11.11 GTK) The room temperature graph in January and August is attached. *The followings are my questions. (a) The room temperature should become equal in January because the window is not opened , but it differs. The room temperature of B) and C) is equal, it differs from A). (b) I think that the room temperature of B in August is right, there is an unusual value in the room temperature of C.

One, why are the temperatures of B and C in January the same and two, what happens in the "dips" in the August run. Based on your set points and looking at the temperatures in January more closely, it would seem quite possible that between 22:00 and 6:00 the ambient temperature never is above 18 ?C. If this is the case (check!), then B and C actually are the same if I understood your model correctly. For the second question, I would suggest using results with at least 10 ts/h (6 min intervals) and plot only the days where the strange behaviour happens. Then look at all the relevant temperatures very closely and see if there may be a logical explanation. What is the default setting? Is this maybe being used for the "strange" time intervals? Possibly compare the results with a very similar day without the strange dip.

Probably, I am considered to misunderstand the method of a definition. I will reread henceforth from the page 186 of "ESP-r_cookbook_dec_2010" again. Is fig.11.17 consulted in order that outside air temperature may define the mode which opens an opening at the time of 18 to 27 degrees? Moreover, I think that a question is asked.

As far as I am aware, the controller uses the three temperatures "low", "mid" and "high" given (18.0, 22.0 and 27.0 in your case) to set up four control intervals: Tamb < "low", "low" < Tamb < "mid", "mid" < Tamb < "high" and "high" < Tamb.

Probably, I am considered to misunderstand the method of a definition. I will reread henceforth from the page 186 of "ESP-r_cookbook_dec_2010" again. Is fig.11.17 consulted in order that outside air temperature may define the mode which opens an opening at the time of 18 to 27 degrees? Moreover, I think that a question is asked.

I have two different versions of esp-r on my computer. The first one is my branch (Sara_Nikoofard) which is based on older revision of development_branch and another one is development_branch at the latest revision. My OS is Ubuntu 10.10. I install esp-r with the following command: ./Install -d ~/esru --gcc4 --compiler_version -4.2 --xml --silent This work perfectly when I install my own branch but when I want to install development_branch, it can't enable xml and give me the following error. However, if I disable xml it works perfectly fine. Any suggestion what is the problem? (if the problem was a missing package then my branch shouldn't be installed which is not the case. I am guessing something else is wrong) I also used this command: "./Install -d ~/esru " to let the esp-r find the compiler versions itself but still no luck.

You can access the first of these via the "active materials" menu. I would suggest trying to start out with this one and set up a model. What do you mean by "movable insulation"? ESP-r offers control "replacement of multi-layer constructions". This may cover what you are seeking? Did you download the CookBook? This has many, many valuable hints on how to set up models and control.

Is the normal absorptivity used at all incident angle, or is there a default directional curve that is used to reduce the absorptivity at higher angles of incidence? Is there a way to input directional properties for solar absorptivity on an interior surface? ::Initial absorption is by angle-of-incidence (I think Paul Strachan would be a good person to answer this in detail). Surfaces are treated as diffuse. There are no mirrors in ESP-r. If you define surfaces floating in a room (e.g. back-to-back polygons) then they are included. ::If you have not done a shading/insolation analysis the direct sun entering the room is treated as a diffuse source, if you have done an insolation analysis then the direct sun entering is directed to specific surfaces. Also, how are solar radiation reflections treated? It is my understanding that only one reflection is considered. Is that correct? Is the reflection considered diffuse, or specular? Is there a way to change that default setting? :: direct radiation entering the room becomes diffuse when it hits the first surface and then the process iterates to distribute the solar to the other surfaces in the room by area and absorptivity.

Does your model have an explicit zone for the cooling panel and you are using an air flow network as "heat sink"? If yes, why not simply control the zone without air flow network? If you are referring to the cooling-panel-to-zone-air surface convection coefficient, then this approach is not realistic, for sure. Are you using a plant network? From the sound of it, I would guess "no". I will send you a simple model (by PM) featuring the "radiant_floor" component which I think Jon was referring to. This model features two simple office zones with cooled ceiling components of type "radiant_floor" in a plant network. I have not tested this with "very thin" constructions, so can say nothing about the numerical stability for such a use. But the model may give some suggestions on a possible approach.

In our experience, countless hours have been saved in automating building simulation tasks, allowing us to focus more on creating quality building models and accurate performance results. We believe that Python is positioned to make a big difference in the building simulation community. To get started, we have the following offer: Send us your scripting problems, and we will solve them for you! In this phase, we are interested most in small well defined tasks. Example problems would be; "In my research, I need to parametrize 100 EnergyPlus files with different U-Values" "We need to convert 1000 files from format *.yyy to format *.qqq" "Our company produces a report for each project, we use Excel to calculate the average Lux levels from radiance, it's easy but boring after 100 projects" Or anything else where you think - "I wish I had an intern do this for me..." (Maybe you are this intern...) Help us by defining your problem with steps taken and the desired result. Send them to: projects at pythonpoweredbuilding.com For all problems received, we will recommend ideas, methods, and modules. We will furthermore select 3 projects to solve and feature in our Workshop during the Building Simulation 2013 conference in France next August http://www.bs2013.fr/. We will also feature these problems on our website; http://www.pythonpoweredbuilding.com. Problems must therefore be free of any intellectual property and will be open to all. For more information and more about us, please visit http://www.pythonpoweredbuilding.com. If you are already a convert and want to get involved, contact us at info at pythonpoweredbuilding.com. Please excuse cross posting, we will direct further updates primarily to BLDG-SIM.

This is using a concrete slab though, and we haven't tried it with a very thin (low thermal capacity) construction. I have not look into the reasons why convergence issues are happening at small time steps, but I do not see the point of modelling at anything less than a few minutes interval for most cases anyways, so it has worked well for us.

Depends on the frequency of your simulation and what else is happening in the model. What would help would be to also list out (or see on a graph) the temperatures in the room(s) along with the heating. Does your model have an energy balance during the assessment period? How are you supplying the heating to the zones (radiant / convective / mixed) and what/where are you sensing? What is the simulation time step? One hour is a very sticky control - try a simulation at 10-15 minute timesteps. -Jon Hand ________________________________________ From: esp-r-bounces at lists.strath.ac.uk [esp-r-bounces at lists.strath.ac.uk] On Behalf Of Dimitrios Sfakianakis [dimitrios.sfakianakis at strath.ac.uk] Sent: 14 December 2012 11:47 To: 'esp-r at lists.strath.ac.uk' Subject: [esp-r] " building:all zones:supplied energy:heating (W)" dubious graph Dear list, I have set up a simple model with a basic controller that keeps the temperature of the zones between 18-22 degC. I want to calculate the required heat in order to maintain the temperature in the zones in this range, so after running a simulation I look at the " building:all zones:supplied energy:heating (W)". However I notice something weird with these values. I am always getting a sequence of large-small values. Am I doing something wrong? Is there something that I am missing?

You can convert this file into a binary climate file via == Question: How do I import an ascii text ESP-r climate file that someone sent me and make a binary ESP-r climate file? Answer: 1. Change to the folder where the ascii file is. 2. Decide on what the name of the binary file you want to create. For this example, assume the file name is bolzano (clm ?file bolzano). Make sure that no file by that name already exists in the folder. Start the climate module with the following command: clm -file bolzano 3. The editing box will show the name bolzano and you click ok. The text feedback will say opened new climate file. 4. choose ?import text file? 5. Select option "import data from ASCII file". The dialog will say "import data inclusive of 1 jan to 31 dec" and you click on 'yes'. 6. The edit box now asks for the ascii climate file and you type in the name of your ascii file and then click on ok. 7. The edit box will now say "update site info as well" and you click 'yes' or ?no? (files exportet from Meteornom require a ?no?). 8. The edit box will ask if the file has day demarcation lines and you say 'yes'. 9. The next thing you will see is the menu. To test the import of data, select graphical analysis and then select January. Then select db temperature and draw a graph to display the data. 10. Exit from the clm module. You will now have a binary climate file which you can associate with your model. == Best Achim On Dec 17, 2012, at 6:02 PM, Arianna Sdei wrote: > Hi Giorgios, > > thank you very much for that.

My understanding is that you want to make a lot of statistical changes in an existing ESP-r climate file. The climate module offers some choices but it cannot read our mind (yet) and it is often easy to just use a spreadsheet tool by exporting your data in it, apply easily the changes that you want in the data and then import the data back in ESP-r. I will normally use the import measured data option from my previous email. The only disadvantage that I see with this option is that you will need an extra addition to your csv file: the start-up days. For example if you want to import 8760 data for each hour of the year and you have 2 start-up days then your csv should have (8760 + 2*24) rows with data. The process is a bit cumbersome but it works fine. General steps: 1st, click create temporal entities file. 2nd, there will be a menu with options from 1 to 5. Go through all these options by actually clicking option 1 (defining a file). It will take you step by step to option 5. 3rd, add temporal entry 4th check Jon's email. If you want to import all 6 columns select the first option for climate data 5th click the entity that you added. You can the define data one by one or import from csv by clicking "! Set display period........." 6th click import column data 7th usually start from the 1st timestep, associate columns, etc. Try this out first with some exemplars for practicing 8th exit and save TDF file 9th click manage associations and then add association to link the data with your model. If you click "list associations" you should be able to see the association of your data with your model.

At the moment im using the thin-zone approach as detailed in exemplar rad_rooms_heat, however it has occurred to me that when a panel is inserted into a surface to link with the thin-zone, it replaces as opposed to augments the construction of the wall that it is on, as obviously it needs to be only a very thin conductive construction for the model to work. I have found that this actually has a noticable effect when the radiant panel is on the external face of the room. So my question is this: is there a more explicit way to model a radiator in ESP-r without building a plant network? (i don't really want to use a plant network as a. it seems rather like overkill to create a whole network simply for one element and b. it only introduces more assumptions and complexity into my model) Basically all that is required is a radiant panel (retaining the construction of the wall behind it) that is maintained at a constant supply temperature; i am not particularly fussed about control laws. If it is possible to also model heat transfer with the wall behind it this would be ideal, though i appreciate that this would necessitate changing the heat transfer in the fabric from 1-D to 3-D.

ESP-r is able to deal with linear thermal bridges (so-called psi values) as an approximation based on some steady state assumptions. The zone geometry interface (prj) can detect different join types for surfaces in a zone and allow you to associate a psi value per m of each of these types of lengths. Heat transfer via linear thermal bridges is reported in the zone energy balance. -Jon Hand ________________________________________ From: esp-r-bounces at lists.strath.ac.uk [esp-r-bounces at lists.strath.ac.uk] On Behalf Of Geissler Achim [achim.geissler at fhnw.ch] Sent: 19 December 2012 16:21 To: olivier bounhoure; esp-r at lists.strath.ac.uk Subject: [esp-r] Re: thermal bridges assessment Hi Olivier I'm afraid you are not the only one with problems with this feature.

One of the models included in the source (src/validation/DSM/stone_simi_1890) uses this kind of representation for a WCH system. It certainly provides the rough kind of control one gets with TRV (which are strongly influenced by the radiant environment in the room) and radiators in rooms (most conventional radiators mostly act as convectors). The thin zone approach could be done - the side next to the wall would be (from the outside to the inside) wall stuff, air gap, metal. The side facing the room would be just metal. Set high hc inside the thin zone. Be careful about the control. You are actuating in one zone but sensing conditions in another zone. The combination is a bit of a mind-twister. -Jon Hand ________________________________________ From: esp-r-bounces at lists.strath.ac.uk [esp-r-bounces at lists.strath.ac.uk] On Behalf Of Andrew Cowie [cn06arc at leeds.ac.uk] Sent: 19 December 2012 15:13 To: esp-r at lists.strath.ac.uk Subject: [esp-r] radiator modelling Hi all, I'm trying to model a bog standard radiator in a one-room model.

It is running a constrained version of Debian so what-the-heck.... I basically followed the standard recipe for setting up a Ubuntu computer (using apt-get) and was able to (slowly) compile in pure-text (and with a few tweaks to the Install script) in both the GTK and X11 interfaces. Smaller executables such as clm pop-up and do their stuff! Imagine, a bit bigger than a match-box.... The bigger beasties don't really start - probably because of memory requirements (some stuff to learn about memory managment). It might be possible to revise the header files in the install folder to constrain the executable size but for an afternoons work to get something working on a new chip architecture is rather nice.

Thus the 3rd item in the *bridge_start line is 2x.39. The first two numbers in the *bridge_start line are used in building code compliance to set a percentage of the overall heat transfer to assume for thermal bridges. For most folk just keep these two at zero (the interface offers a choice for this). The last value on the *bridge_start line is the UA for the zone. In the above example it is zero because the automatic facility in the interface was not used.

ESP-r is able to deal with linear thermal bridges (so-called psi values) as an approximation based on some steady state assumptions. The zone geometry interface (prj) can detect different join types for surfaces in a zone and allow you to associate a psi value per m of each of these types of lengths. Heat transfer via linear thermal bridges is reported in the zone energy balance. -Jon Hand ________________________________________ From: esp-r-bounces at lists.strath.ac.uk [esp-r-bounces at lists.strath.ac.uk] On Behalf Of Geissler Achim [achim.geissler at fhnw.ch] Sent: 19 December 2012 16:21 To: olivier bounhoure; esp-r at lists.strath.ac.uk Subject: [esp-r] Re: thermal bridges assessment Hi Olivier I'm afraid you are not the only one with problems with this feature.

Only one CFD zone is possible. Yes, you can add "blockages", e.g. "furniture" or "half height walls". However, these cannot be coupled to thermal properties (hot wall or such like) to my knowledge. They are flow barriers, only. You can couple the CFD zone with an air flow network. I do not quite understand your first question, but if it is an array of air outlets exhausting air into a larger void (atrium or some such space), then this should be possible via CFD in the large zone and afn for the air exhausts.
