2023-12-05 07:43:22 -0500 marked best answer ResStock Turn HVAC Off in Apply Upgrade Error

Hi,

I am using ResStock v2.2.4, OpenStudio v2.9.0, and EnergyPlus v9.2.

My housing_characteristics tsv files are edited to have the following distributions:100% Propane in Heating Fuel.tsv and 100% SEER 15 Central AC in HVAC System Cooling.tsv.

This means I am fixing the baseline HVAC equipment.

I am trying to use PAT to turn off HVAC equipment, keeping all the other building characteristics in the sample the same.

I have done this by specifying in the Apply Upgrade Measure Option 1 field;

HVAC System Heating Propane|None

and similarly in the Apply Upgrade Measure Option 2 field:

HVAC System Cooling|None

Both of these parameter|option pairs I sourced from options_lookup.tsv.

Apply Upgrade Measure

When I ran my simulation, all of my columns in results.csv in localResults were blank, and I could not find an enduse_timeseries.csv file in any of my data_point.zip folders.

Any idea why this is happening?

2022-09-21 11:26:17 -0500 marked best answer Setting annual ground temp in PAT project

Hi,

I am using OpenStudio v2.9.0, EnergyPlus v9.2, and ResStock v2.2.4.

I would like to override the default E+ ground temp of 18 deg C and set the ground temp equal to the indoor setpoint of 70 deg F.

Is there a OpenStudio or EnergyPlus measure I can add to my PAT workflow to do this? I am not able to edit the IDF file directly, since it is automatically generated through OS-PAT.
