I am wondering whether EAp2 requires a project to fulfill the Interior Lighting Power Allowances in Section 9.5 in ASHRAE 90.1-2007 if Option 1 - Energy Modeling is used? The prerequisite language

We, as a team are getting ready to submit our design final submission and prepared a report to respond to each individual comments made by GBCI.

I am modelling a large multi use building where the peak occupancy never rises above ~70%. Different areas of the building are used on different days but never all at once.

If a project is being demolished but the slab and some columns are being kept, would that be considered a major renovation since we are not given the option of redesigning the orientation of the bu

G3.1.1, Exception "d" requires laboratory spaces with a minimum of 5000 cfm of exhaust to use a baseline system type 5 or 7 that reduce the exhaust and makeup air volume to 50% of design values dur

I am working on a high-rise residential building with VRF. The building envelope is heavily glass, so the owner has decided to also install a hydronic heating system at the building perimeter.

The brewery I am modeling has large percentage of energy consumption associated with the process load.

My proposed design has multiple AHUs supplied from a dedicated outside air AHU (DOAS) . The DOAS will be over 20,000 cfm and will have energy recovery.

Hi there, Im modelling a corner building, which has two adjacent buildings so only the façades facing the street are in contact with the exterior environment.

Hi All, I am modelling a VRF system using ApacheHVAC in IES. But have no idea which prototype to choose.
