I am currently working on a fire station building in NC and I'm using HAP 4.8 to model this building vs. the baseline.

The building has two of its bounding walls shared with its neighbour buildings. First question is, is a shared bounding wall considered part of the envelope?

Hello, We have an existing central plant that will be serving new building. How do we model this? Existing central plant will service one existing building and new building.

If the local energy code is more stringent with respect to building U-factors does the baseline model need to meet the local energy code?

If air economizers are not required to be modeled in the baseline system due to climate zone (4a) can you model the proposed with economizers if in design and not model economizers in the baseline?

Our project is an office/retail building that is to utilize water source heat pumps for retail and water cooled self contained VAV units for the office floors.

Hi, I previously filed an innovation credit with my design preliminary submission and received an comment from GBCI therefore it is pending.

I have a question about thermal blocks in multy family residential buildings. I'm working with a building that has 4 floors and totly 7 appartments.

Hello everyone, I am working on a residential project. The proposed case HVAC system is Water loop heat pump with cooling tower and natural gas based condensing boilers.

It's clear from the credit language and LEED Online form that California Title 24-2005 Part 6 can be used in place of ASHRAE 90.1-2007 as a baseline when creating an energy model.
