[Equest-users] ASHRAE 90.1 building and efficiencies

[Tomlinson, Scott]

Hi all,

I'm somewhat new to eQuest and still trying to get my brain around it.  One big issue I am having is my code building is actually more energy efficient then my design building.  I did a test case where I quickly modeled a generic building and toggled the HVAC system types to see what effects the systems have on the building.  I modeled the code building as a Packages single zone with furnace (ASHRAE 90.1 system 3, PSZ-AC) and my design building as a Packaged VAV with HW reheat (ASHRAE 90.1 system 5, Packaged VAV w/reheat).  My code building is getter considerable better performance than the design building.  Am I modeling the code building incorrectly?  Any help would be appreciated.
