In the plase of construction i have an HVAC equipment not certified by AHRI.

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?

We are working on an ASHRAE 90.1 model in Nevada and are adding the solar information manually to the LEED online forms, post energy modeling (so our solar energy is not appearing on the software g

Table 1.4.2A (Shading & Orientation) asks for the Above-Grade Wall & Vertical Glazing Area by Orientation.

I modeled a 10-story hotel building. Since the majority of space are hotel rooms, which are considered to be Residential spaces, the primary Baseline HVAC system type is System #1.

We are doing LEED certification for a building in a campus which already has exterior lighting installed.
