In the building for which I'm preparing energy simulation, there's an underground garage which is heated only by used recirculated air from offices above.

Dear Sir/Madam We are certifying a large retail mall which have a large carpark block ( five levels).

I have a C&S medical office building that is 88% tenant space (by area) and am trying to figure out how to correctly document the owner/tenant % of the building energy cost for the Core and She

How should one model existing glazing U-Values and Solar Heat Gain values when they are unknown (they were installed 24 years ago). I am referring to the Baseline Model ASHRAE Table G3.1 5f

My question is currently about the scope of certification, but has it main impact on the building's energy performance. We are currently working on a major renovation and extension of an office bu

Hi everybody! I´m looking at several glass options for a building project and I want to make sure I pick the most cost-effective and energy efficient options available to me.

For the baseline model can I please confirm the following; Design Cooling SAT: According to ASHRAE 90.1 G3.1.2.8 should the supply temperture be 11 deg C less than room temp.

If your climate zone does not require air econmizer for baseline systems (90.1 2007, climate zone 4a) are you allowed to model your proposed systems with economizer, per design and not have economi

Hello:) In which programs are you doing energy simulations? Did you have some problems with GBCI concerning the type of the programe that you chose? What with IDA ICE for example. Thanks:)
