Hi! I am conducting a LEED v2009 EAp2/c1 energy model for a nonresidential building that is more than 5 floors.

When claiming DHW savings due to low flow fixtures, i use the calculator in Table 1.4 to come up with my peak baseline and proposed DHW flows, which it says should use data from WEp1.

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.
