==== Information from Jon Hand in regard to IPV: =====
A summary of the steps below:
IPV lets user choose some parameters of interest (temperature, MRT, RH, energy
etc) and the IPV output lists these. There are two types of scaling, both scale up energy. Zone scaling can be done if user models say one zone and wants to include x such zones in the final result. Time scaling can also be performed by selecting a period in each season (usually 3 or 5 weeks in as many seasons) and simulating. Results from these simulations are scaled up for the whole season based on degree days.
ESP-r interface commands in the order I entered them:
1. To get into the ipv menu:
model context > integrated performance views > give an ipv file name > leads to "options for assessments" menu I chose "5 seasons typical week"
2. To scan climate and automatically select typical weeks:
re-scan climate > scan climate list
3. To set up degree day ratios to fill in multipliers for scaling:
re-scan climate > for day ratios > heating temperature (choose default) > cooling temperature (choose default) > search for typical week > weighting factors (choose default) > look at next season (4 times)
4. To set up output for I2PV:
report format (until you get java)
5. To choose performance metrics:
Performance metrics (choose some)
6. To set up zones for energy output:
Demand sets (this means energy demand) > zones (pick some zones)
You can also add a second demand set which is another grouping of zones if you want to list out zones in more than one group
7. Time step data (optional):
Turn on "time step aggregate" if you want column data for all days and time steps. With this turned off there is no listing for time step data. Jon suggested you try running simulations with and without this toggle to see the difference.
8. To simulate and extract reports
simulation > integrated performance view > run simulations > silent (then after simulations finish) > extract reports > silent > all
This should generate the I2PV input file as well as coordinating the generation of the results files which can be used for other purposes.

Betreff: [esp-r] Res: AW: Scaling up my Model
Hello Achim,
I have clicked that option (even before posing the question on the mailing list) and what I get is a pop-up window that says:
"Normally an integrated simulation is invoked by which
the heat, fluid, electrical power and light flows within
combined building/plant models may be evaluated."
and then disappears. Then I click "integrated simulation" and I get the regular menus and simulation options. When I execute the simulation I don't see anything that indicates that the pre-defined weeks were used. When I graph the ambient climate temperature shows a typical ambient temperature profile with no repeating weekly temperature profile as I would have expected. Where did I go off track?
Regards,
Ian

Hi Ian
look for the "model context - integrated performance view" (ipv) menu. This allows for automatic calculation of the defined weeks, input of scaling factors etc. It produces a concise summary of the results.

Hello ESP-r Community,
Hence the last note I have looked into the scaling feature of ESP-r. I have successfully followed the steps outlined in chapter 6 of the ESP-r Cookbook (version Nov 2008). I have created a weather file for my city (Nantes) and selected the typical weeks for the winter1, spring, sum! mer, fall and winter2.. I have updated the "climatelist" etc... but then the chapter in ESP-r Cookbook Chapter 6 just stops and does not describe how execute simulation using the 5 ideal weeks / scaling option. Is this an automatic scaling option or do I have to run the simulation 5 times with each respective "ideal week" and then self-scale the results? Any ideas?
Cheers,
Ian

Hello ESP-r,
I am looking for all the information possible related to scaling up a model. The
cookbook states that scaling up skills and working practices to cope with the
level of complexity found in realistic projects has traditionally been
accomplished via mentors or workshops. Since those two options are not really
available to me does someone have a document that covers these details?
The cookbook briefly mentions some techniques (e.g. chapter 6 talks about for
example, how to achieve annual heating and cooling for a whole
building without
simulating every day etc.... i.e. it reports initial scaling factors that can be
used to convert from short period
assessments to seasonal performance data.).
Regards,
Ian
