Is there a way to get timeseries temperature data for each individual layer of the envelope object like wall or roof. For example, if I have a BuildingSurface:Detailed object named South_wall which is assigned a Construction object Exterior_wall made up of different Material objects as mentioned below, then is it possible to get hourly temperature data for the inside and outside surfaces of each individual layers of the Construction object for each BuildingSurface:Detailed object

Construction,
Exterior Wall,
bevel_cedar_siding,
Bldg_paper_felt,
OSB_3/4in,
wall_consol_layer_empty_cavity,
Drywall_1/2in;

I know we can get the temperature data for the inside and outside surfaces of the BuildingSurface:Detailed object using the Surface Inside/Outside Face Temperature output variable. But this does not provide data for individual layers.

Thanks @Aaron. The Conduction Finite Difference algorithm solved my problem.

I already have some scripts written using Eppy and migrating to a different tool at this point wouldn't be a good idea.

I have a script which uses eppy to generate an Ideal Air Loads (IAL) model from a model with a complete HVAC system. I want to do further processing on this IDF and it is necessary that I have the same order of the objects as in the original IDF (which has a sorted order based on IDF Editor 1.31). Is there a way to retain the original object order in eppy. I am using the idf.saveas() function. Probably there's a different function?

Also, is there a way to retain comments made using '!' ? IDFEditor retains them but can eppy?

Thanks Santosh! I figured out a way to do both the things using a combination of Eppy and plain text manipulation. I mig

Hi Eric, thanks for the answer. I'd just like to add that DView does not read the timeseries data accurately from the .c

I am trying to convert the following IDF file (an ASHRAE 90.1 prototype) from version 8.0 to 9.0 using the IDF Version Updater which comes with EnergyPlus 9.0 installation.

But I am getting the following error - Error starting Transition-Vx-x-x Program: 2

Initially the conversion was failing at the first conversion (that is from V8.0 to V8.1). Then I downloaded these set of files and followed the instructions. Now it works fine until V8.4 but gives the same error after that.

I can see that the files that I downloaded from the above link only include transition files upto V8.4. The rest of the transition files on my computer (from V8.5 to V9.0) are from the EnergyPlus 9.0 installation. Can someone point me to the updated transition files or any other way to fix this problem?

Thanks, that worked.

I am modeling a lab building with a lot of equipment like steam sterilizers with direct steam consumption. I added steam equipment loads in the spaces and I am getting the MBtu's of steam consumed by the building in the OpenStudio output. However, I want the output in terms of natural gas used to produce that steam. Is there a way I can model a plant loop, add these steam equipment loads on the supply side and have a natural gas fired boiler producing steam on the demand side ? How can this be done in OpenStudio? Or is there any other way I can model steam consumption in spaces and natural gas consumption as the output?

Thanks for the answer @Julien. 19k karma points is amazing! After you short derivation, I read about the fraction lost/r

@Eric Ringold I upvoted the request. Thanks for adding it.
