Observing the CHANGELOG for ResStock (https://github.com/NREL/OpenStudio-Bu...), I noticed that some housing characteristics are based on RECS 2015 data whereas others are using RECS 2009 data (i.e. occupancy schedules vs. HVAC System Cooling).

Is there documentation that details the source for each of the probability distributions within housing characteristics? I guess more specifically, which RECS data was used for each housing characteristics TSV file (assuming RECS was the sole source)? I ask this question particularly for project_singlefamilydetached of ResStock 2.2.4.
