Using PAT Tool v.2.8.0 with ResStock's project_singlefamilydetached to run analyses.

Was wondering if there's a way to force PAT tool to create an end-use load profile where there are zero unmet hours? I'm currently using the ASHP, SEER 16, 9.0 HSPF upgrade option on a building stock that's fixed in a IECC Climate Zone 6 area. There are some buildings that will have up to 30% of the year having hours that do not meet the heating setpoint temperature. During some of these hours, the zone air temperature and the zone thermostat temperature will differ by up to 10° F.

My objective is to run PAT tool with any HVAC system and observe the end-use load profile on the basis that it can meet heating load 100% of the time out of the year.

Hello everyone,

I'm loading project_singlefamilydetached from ResStock into the Parametric Analysis Tool, and an issue I'm running into is that whenever I have an upgrade applied, my results.csv file does not produce ANY entries for the building_characteristics_report columns. Entries for simulation_output_report columns are produced fine, and I see my upgrade name filled out in the "simulation_output_report.upgrade_name" column, so I know my entry for Apply Upgrade is not being ignored.

However, when I choose to skip the Apply Upgrade measures, THEN my results.csv file produces entries for the building_characteristics_report columns. Is anyone else experiencing this issue? I really don't know what the problem is, since I have the "Building Characteristics Report" measure unchecked for both situations.
