We are modeling and commissioning a dormitory building where 4 pipe vertical fan coils have been installed.

I want to clarify that ASHRAE 90.1 Appendix G 2007 (sec 5.4, 6.4, 7.4, 8.4, 9.4 and 10.4 ) is applicable to Option-1 Whole building energy simulation for both EA Prerequisite 2 and EA Credit 1.

I think I posted this question on the wrong page beforehand, so I'll post it again here. We are trying to account for a CHP plant near our project in our energy model.

The project consists of upgrading a liquid helium (LHe) to gaseous helium (GHe) conversion and compression system.

Hi, I have a question about baseline building HVAC minimum efficiency.

In the courtyard of the building that I’m modelling two charging columns for electric vehicles are going to be installed. Shall I consider them as process energy?

EA Credit 1 allows for different percentages of energy performance for "Existing Building Renovations" than for "New Buildings", but there does not appear to be any information in the reference gui

I'm performing an energy model that is a renovation of an existing structure. The existing structure has a sheet metal roof, two vertical sheet metal walls, and 4" concrete slab.

I have a doubt concerning the percentage of vertical fenestration I have to consider for Table G3.1 5.c. Let me give you an example.
