Table G3.1 in Appendix G requires only conditioned space be simulated as being both heated and cooled in the proposed design.

Hello, When I generate the EAc1 Summary Report in HAP I have a negative percent savings in space cooling and heating in the performance rating table.

Hello Marcus. The fenestration supplier of a project gave us SHGC values from a simulation. We would like to know if it is acceptable for LEED simulation.

The efficiency of the boiler that I’m modeling has to respect Table 6.8.1F of ASHRAE 90.1:2007.

Hi All, Are baseline building rotations necessary for a new building that is connected to an existing building. Note that the new building is being modeled as a stand alone.

Hi Guys, I am a energy simulation engineer. Now I have a project which uses the district steam supplied by the local government as heat source.

I am modeling a LEED building that includes a snow melt system. The system is served by the building's hot water boiler.

We are performing a review of an energy model for a project that is a major remodel of an existing space with addition of new square footage.
