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/...

Photovoltaics offset energy usage

NC-2009 EAc1: Optimize Energy Performance
posted by William Jencks on Aug 10, 2010, 7:06 pm

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?

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...
