[Equest-users] FW: Solar panels

[Alan Crittendon]

Page 274 of BD+C 2009 Reference Guide directly answers the question:  2.1
model the systems directly in the proposed design energy model.

 

Now all I have to do is figure out how to do it!!!

My LEED-NC v2.2 Reference Guide p188 says "On-Site Renewable Energy and
Site-Recovered Energy costs are not included in the Proposed Building
Performance (this is a LEED for New Construction exception to ASHRAE
Standard 90.1 G2.4); therefore, these systems receive full credit using the
PRM".examples include PV.

 

p264 of the BD+C 2009 Reference Guide has a similar note about using
harvested free energy for EAC1 performance.

 

As far as CIRs I'm not sure, but LEED has always been pretty clear that you
count on-site renewable energy production for both EAC1 and EAC2.

I sent this yesterday but have a couple more things to add:

 

1)  how does LEED deal with solar power and does Section G2.4 ASHRAE
90.1-2007 just mean that you can't take credit for the utility buying back
the extra energy or cant model at all?  

2)  Has there been any CIRs that discuss solar PV from LEED?

Does ASHRAE 90.1 allow the use of solar panels when calculating the proposed
bldg?  if so how do you model them?
