Is there a standard way the USGBC wants the R-value of a wall assembly to be calculated taking into account the framing factor or thermal bridging that occurs with metal studs?

According to ASHRAE 90.1 (2007) Table G3.1 - 10 c, "where no heating systems exist, HVAC system shall be assumed to be electric".

We are struggling with some definitions from Table 9.4.5 of 90.1-2007.

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.

Condition: I have a completely unconditioned garage located in the cellar. There is no heating. No cooling.
