[Hap-users] HAP ENERGY MODELING FOR LEED - Model Supply Air Temperature Reset?

[David García]

Hi everyone,

I am developing an Energy Model for LEED Certification following ASHRAE Standard 90.1-2007 Appendix G. The building has 7 stories above grade, one story below grade and it is a mix used, office (5 stories) and retail (3 stories). Baseline Building HVAC System is 8 type. I m unsure how to model Supply Air Temperature Reset.

On the one hand, for the Design Supply rates I use 11ºC of temperature drop (24-11= 13ºC). On the other hand, I use Temp. Reset by Greatest Zone Demand adding 2.3ºC to Supply Temperature (13ºC). Can this work?
