Revision history [back]

I am working through a LEED v4 energy model and am trying to reconcile the unmet load hours that I am getting from the Range command in IES VE. Unfortunately I am finding that the setpoints it is referencing are the HVAC zone setpoints, not the room setpoints.

This presents an issue in some areas, for example, where I have an open office with a nearby storage room that is on the zone with it. The acceptable temperatures for the storage room are 60°F-80°F cooling. The open office setpoints are 70/75. Even though the storage room stays within its acceptable range, the fact that it is outside of the open office setpoints (since the open office is the master room and its setpoints drive the HVAC zone setpoints) produces UMLH.

Are there any insights on how I can work with IES VE to get it to ignore UMLH if they are within a room's acceptable range?

I've also looked at this previous post, for reference.
