From jon at esru.strath.ac.uk Tue Jan 17 14:57:26 2017 From: jon at esru.strath.ac.uk (Jon Hand) Date: Tue, 17 Jan 2017 14:57:26 +0000 Subject: [esp-r] a download-from-github and install script for ESP-r - testers requested. Message-ID: Hello all, Getting a coherent source distribution of ESP-r to compile takes several steps. Aizaz Samual and I have written a bash script that automates the process that does all the git cloning and rsyncing of folders. Currently it takes the Master from github. I have tested it on a couple of Linux boxes and OSX as well as within a MSYS2 environment in Windows 10. It detects the OS and revises the feedback and options depending on which OS it finds is also checks for a number of common dependencies. More testing is needed. If you want to give it a try here are links to the script. Let me know your suggestions so I can improve it. The default is to put the compiled distribution in /opt/esru on Linux and OSX and C:/ESRU on Windows. I do not have the facilities to try it on Cygwin (any volunteers?) We would hope that it could go in the top level of the github repository. The Readme is shown below: Overview of download_and_install_ESP-r.bash The script download_and_install_ESP-r.bash automates the task of grabbing the various ESP-r repositories from github, assembling them into an ESP-rMaster folder and then, optinally, running the ESP-r Install script to build and placing the ESP-r distribution into a standard location for the operating system you are using. It tests for a number of dependencies e.g. compilers and a git client. It should work on most Linux distributions as well as OSX and the MSYS2 environment on Windows (but the git command line agent is not so rubust within MSYS2). It is suggested that you create a folder and place the script in it and this is where lots of temporary folders will be created as well as a persistent ESP-rMaster folder. You may need to make the script executable to use it and for Linux and OSX you will need to run it with sudo.

Message-ID: Greetings fellow modeling enthusiasts, I was wondering if there is anyone out there who has had experiences with zonal airflow modeling, using energy modeling tools besides ESP-r (e.g. E+, IES-VE etc.) How do they compare to ESP-r in terms of accuracy (e.g. is buoyancy modeled?), solution of the system (conservation of mass?), interaction with the thermal domain, reporting (can I pull the pressure at different nodes), parameter definition and ease of use?

The steps are basically the following: In cetc/h3kmodule.f90 add the parameter definitions ? just follow the general structure of variables given. You will need to give the type (somewhere close to the beginning of the file) !Used by casual.F Type(ReportVariable) :: rvXX, rvYY (whatever name you fancy, the ?rv? is ?report variable? ...) ... and also the definitions similar to rvInsolationTotal%VariableName = 'building/*/insolation/total' rvInsolationTotal%MetaType = 'units' rvInsolationTotal%VariableType = '(W)' rvInsolationTotal%Description = 'Solar gains admitted through glazing' Call AddVariable(rvInsolationTotal) somewhere later on in the file. The ?*? in above example allows for zone naming. Likely, you will want to have a second ?*? for the lighting zone in a given zone. Then, in casual.F (probably necessary, because the variables of interest are not available via a program-wide common, I think), you will need to call ?Addtoreport? like so: call AddToReport( & rvBldZnLightPow%Identifier, & Cas_Lights(iZone), & cZone_Chars) where of course the ?rvXX? is the name you chose in step 1. Cas_Lights is the value and cZone_Chars is the zone name. If you also have the lighting zone, simply add the appropriate variable after cZone_Chars. Probably it is best to place this close to where the ?final value? per time step is available. The procedure is actually quite straightforward and there are many examples in the code from which to learn. Recompile (depending on your development environment, make sure the relevant object files actually have been created newly - make does not always accept the .f90 and attached module as changed!), rerun and check out.dictionary ? the new variables should be available. Good luck!

The steps are basically the following: In cetc/h3kmodule.f90 add the parameter definitions ? just follow the general structure of variables given. You will need to give the type (somewhere close to the beginning of the file) !Used by casual.F Type(ReportVariable) :: rvXX, rvYY (whatever name you fancy, the ?rv? is ?report variable? ...) ... and also the definitions similar to rvInsolationTotal%VariableName = 'building/*/insolation/total' rvInsolationTotal%MetaType = 'units' rvInsolationTotal%VariableType = '(W)' rvInsolationTotal%Description = 'Solar gains admitted through glazing' Call AddVariable(rvInsolationTotal) somewhere later on in the file. The ?*? in above example allows for zone naming. Likely, you will want to have a second ?*? for the lighting zone in a given zone. Then, in casual.F (probably necessary, because the variables of interest are not available via a program-wide common, I think), you will need to call ?Addtoreport? like so: call AddToReport( & rvBldZnLightPow%Identifier, & Cas_Lights(iZone), & cZone_Chars) where of course the ?rvXX? is the name you chose in step 1. Cas_Lights is the value and cZone_Chars is the zone name. If you also have the lighting zone, simply add the appropriate variable after cZone_Chars. Probably it is best to place this close to where the ?final value? per time step is available. The procedure is actually quite straightforward and there are many examples in the code from which to learn. Recompile (depending on your development environment, make sure the relevant object files actually have been created newly - make does not always accept the .f90 and attached module as changed!), rerun and check out.dictionary ? the new variables should be available. Good luck!

The way I translate that is that if the setpoint is 500lux, the lights will switch off at 750lux.

It is a mix of analytical techniques (e.g. detection of rectangular enclosures) and the grinding of points on surfaces and then geometric checks to see what 'other-points-in-the-zone' can be seen from each grid point. It works for zone enclosures of arbitrary complexity (i.e. the polygons forming the room can be of arbitrary complexity) with or without internal mass surface pairs. I have tested it with rooms approaching 90 surfaces and with polygons up to 48 edges. In most situations we find the calculated view factors are quite accurate. And yes the method is rather fast on modern computers. Also the method allows for people to include MRT radiant sensors within zones and the viewfactors between such bodies and the room surfaces to be calculated. This allows position specific comfort to be assessed. The only tweaks needed might be in the case of frames with small dimensions where the density of the grid would need to be increased. The original work was done more than a decade ago but there should be a publication in the ESRU web pages which describes the numerical approach in detail. There are also comments within the code.

Message-ID: Dear practitioners in the field of Architecture, Engineering and Real Estate Development, We're conducting a survey about life cycle performance at early design stage. Your help would be very much appreciated. Would you please take a few minutes to answer this questionnaire? Also, could you please forward, post or publish this call to all your colleagues? Hereunder the introduction to the questionnaire: [cid:image001.png at 01D2F645.BC7DE7F0] Who may answer the questionnaire? Practitioners from architecture, engineering and real estate development sectors. Please note that this particular survey is not targeting researchers or educators. If you are not concerned by this survey, feel free to forward this email to your colleagues, they will be able to answer using the following link: https://fr.surveymonkey.com/r/LCA-survey What is this survey about? Climate change and energy consumption impacts require us to consider the full life cycle of a building but how can we effectively take it into account in a realistic design process? This survey is part of a PhD project conducted at EPFL and aims to help developing a user-centered method for life cycle assessment at early design stages. That is why we need your contribution! Why should you answer this questionnaire? By offering a few minutes of your time, you contribute to a research effort, which could have a very positive influence on the tools you use or could get access to, and will support the integration of more holistic sustainability approaches in practice. If you are willing to get access to the results of the survey, please leave us your email address at the end of the questionnaire and we will send you a complete analysis report with all results in a few month. Answering the questionnaire will take only 8 minutes of your time, it has a non-commercial purpose, and all collected data will be treated anonymously.
