I have a roughly 48,000 sf church with the following breakdown by area and hours of use: 1st Floor: 4,100 sf Multipurpose Space used 16 hours per week 8,200 sf Common Space used 72 hours per week

LEED Interpretations state that hard-wired lighting in residential units must be modeled identically in the baseline and proposed cases. Does this apply to college dormitories as well?

Hello, I am Sangmin of SGS Korea. I have a few question regarding Interactive 90.1-2007 Compliance Forms - building envelope compliance documentation (mandatory provisions checklist). 1.

I had a response from an energy model reviewer indicating my r-value calculations are not acceptable because we failed to derate the 3.5" R-11 batt insulation per Table A9.28B of ASHREA 90.1-2007.

Hi, How is possible to consider Exterior Lighting Energy Consumption on a Multiple Building Process where there is no specific boundary per each building?

Hello, Is there a guide or list somewhere as to what materials are acceptable to use for insulation? We want to know what options we can use. Thanks. John

Does anybody know what is the average of energy cost savings reported to LEED/USGBC? We are just wondering to compare all projects overall. Thanks

In the building that I’m modelling there are two floors. On the ground floor the conditioned area is 3393m^2 and on the first floor it is 2689m^2.

Dear All, I want to model daylighting sensors for an open plan office.

Do the refrigeration system such as walk-in coolers or refrigeration cases must be detailed modeled in the simulation program (E+)? or is it possible consider them as a process loads?
