I am working on a LEED project in Qatar and wanted to query USGBC on using aircooled chillers in the baseline building instead of water cooled chillers.

We are currently building a school and one of our subcontractors asked if ceiling tiles count towards Energy and Atmosphere Credit 1?

To simulate the exterior lighting in Baseline Building, i have to model it according table 9.4.5 of Standard 90.1? Or it is not possible to earn points for exterior lighting systems? Thanks in ad

We are working on an eQuest model of a very unusual building. It was constructed in 1911.

Planning to use Carrier variable speed heat pumps split systems on a project and I am looking for data files to assist in this. The manufacturer rep is not aware of anything that can help.

I am working on an energy model for a Factory that was registered under LEED v3. The factory has no HVAC system except for some ventilation fans.

I’m modelling a school in which a conference room is going to be placed. The baseline shall be System 5 - Packaged VAV with reheat.

What is the correct approach when simulating pumps and fan power in the proposed case?. size the electric motors with the bhp or the next commercial motor size.
