Hi, I'm running an energy simulation on a three floors office building. This building have also an entrance hall. The HVAC system for the office part is a VRV Fan Coil System with external air con

Seems that some of my questions are not easy to answer. Here is another question for the same lab project. Fan system Power limitations are calculated according to Table 6.5.3.1.1A of ASHRAE 90.1-

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

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).

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

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
