Revision history [back]

Hi all,

I am using ResStock v2.2.4 and OpenStudio v2.9.0.

I am trying to simulate a residential community in northern Georgia. Specifically, I noticed that regardless of the year of the simulation, or the HVAC system in place (propane furnace, ASHP, MSHP ect), for the same 6 building id #'s, I would always get huge unmet cooling hours for only 6 specific buildings out of the 100 simulated.

Notice how the unmet hours are similar in magnitude as well. This leads me to believe that is an issue specific to these 6 particular buildings.

I know that there was a similar issue caused by unheated vs basements as separate thermal zones that was documented by a colleague of mine through this post: https://unmethours.com/question/44990/high-unmet-cooling-hours-for-finished-basements-served-by-central-cooling-systems/

However, this problem is different in that it only affects 6% of the buildings, while the above problem in the url was affecting all buildings.

Any guidance or advice would be appreciated.
