Hello, My project team is looking into doing the energy modeling for a project in house, and I am wondering if anyone has a sense of how much experience is necessary to learn to use eQsuest softwa

In Bulgaria we have a project, which if using the Building Area Method of ASHRAE 90.1-2007 meets lighting requirements; however, using the Space by Space Method requires adjustments to be made to

The fan power calculated by the formula presented in APPENDIX G3.1.2.9 of ASHREA90.1-2007 is the sum of all the fan power including supply fan,returen fan,exaust/relief fan.

Minimum outdoor air shall be model identically in both the cases. I am confused which outdoor air should be taken from either from IEQ baseline or from actual.

We are looking at a high rise residential project, to be NCV2009. Our electrician is stating all hallways need occupancy sensors.

Hello, our project has 40 electrical table top water heaters. The electrical input is 2 kW and 5 liter storage. What is the right way for modeling the baseline builing water heating equipment?

ASHRAE 90.1 -2007 has following clause. 6.4.3.9 Ventilation Controls for High-Occupancy Areas.

I am modeling a shell office building project for LEED 2009 using ASHRAE 90.1-2007 as the basis for modeling.

our project has a district heating with a flat rate of 0.012$/kw and we calculated the virtual rate to be 0.08$/kw can we use the virtual rate or do we have to use the rate provided by the service
