<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am modeling an existing building for Energy &
Atmosphere Credit 1: Optimize Energy Performance. In LEED and table G3.1 No. 5(a)
of ASHREA Standard 90.1-2004, it states that “the baseline building performance
shall be generated by simulating the building with its actual orientation and
again after rotating the entire building 90, 180, 270 degrees, then averaging
the results”. However table G3.1 No. 5(f) of ASHREA Standard 90.1-2004
states: “for existing building envelopes, the baseline building design shall
reflect existing conditions prior to any revisions that are part of the scope
of work being evaluated.” Would this mean that you do not need to simulate
the building for the four orientations? It just doesn’t seem to make
sense to simulate the building in such a manner if it is existing. I am new energy
modeling for LEED credit and sincerely appreciate any assistance.</span></font></p>
