<p class=MsoNormal>For the purpose of LEED credit EA c1 Optimize energy
performance, is it possible to account for on-site renewable energy using
option 1 (whole building energy simulation). It seems that you can
using 1 of two options: modeling directly onto building modeling software or
using exceptional calculation method, but I am not clear on the actual
procedure. Which one of the modeling software is capable of
modeling PV renewable energy systems?<o:p></o:p></p>
