We are integrating an extensive green roof in the project (7 cm of substrate) with sedum vegetation. Is there a way we can take credit for the insulation value of the roof in the energy...

I just read (in a really scarey article by an attorney who'd describing the legal implications of buildings whose certifications are challenged and revoked) that we must now provide one-year...

If there are 5 building structures in the project, shall I perform separated energy simulation models for 5 individual structures, or 1 model as a whole?

Hi!

The design flow in baseline is determined with a temperature difference of 11 C (G 3.1.2.8). This design flow and the fan power (G 3.1.2.9) will give you the specific fan power (kW/m3/...

If 100% of your building energy usage is offset by a large photovoltaic array which is outside of your LEED project boundary, does this qualify for all 19 points under EAc1?

I am filling the LEED online template for EA p2, and I face a problem. Now I can get the building unmet load hours from eQUEST BEPS report, but I don't know how to split the heating unmet load...

I can’t find anywhere how detailed the thermal brides should be calculated in the model. In the simulation program I use you can use some default values or calculate the separately in every...

Hi!
When you determine your building envelope for a baseline, a major renovation in an existing building, it's clear that "the baseline building design shall reflect existing conditions...
