Hi, I am working on a building which includes DOAS units with energy recovery cores on the proposed systems. The baseline systems do not require energy recovery per ASHRAE 90.1-2007.

HI We have a workshop building targeting for LEED NC.

Dear all, I had a reviewer comment for my basecase walls and floors assemblies that were modeled with U-value higher than the appendix G values by a mistake, however, after correcting

The EAp2 worksheet requires Title 24 sheets PERF-1, ECON-1, and UTIL-1 when the energy modeling program is EnergyPro.

Hello, I have a question on which HVAC system type to choose for the baseline case for a project consisting of 4 buildings.

I am not sure that I am interpreting section G3.1.3.14 in the correct way.

Hello, I am wondering if it is allowed to add additional exhaust fans into the proposed model to extract more hot air from the zone and save more energy on cooling. Is this possible?

Based on ASHRAE 90.1, the chilled water pumping power must be 22 W/gpm and does not mentioned the effect of pumping head.

We are working on a project which is mixed use facility (6 storey/G+5) . The first & 2nd floor is used for office & remaining for residential.

Markus, thanks a lot for your answer. Another issue appeared to this Heating only system - Baseline modeling of DHW (Domestic Hot Water). The Proposed model is having a gas fired boiler to provide
