"-That's the exact issue I found.  I included a note on both SSc8 and the lighting tab on EAp2 (?) indicating such.  In my opinion, ASHRAE 90.1-2007 should be followed in all cases, not Addendum 1 as listed in SSc8 (which is really 90.1-2010) as it was not applicable to the design of the project."

We haven't submitted it yet, so I can't attest to the leed regimes' willingness to except it.

Hi there,

 

I came across a strange thing on a LEEDv3 (v2009) project. One team was working on SSc8 and the other on EAc1. While the exterior lighting power density should be calculated in accordance with A90.1-2007, section 9, Table 1 in both cases, the SSc8 template (referring in the description field to A90.1-2007) was automatically looking up A90.1-2010 values (allowable LPD) while EAc1, table 1.4 was using A90.1-2007 values. I know that usually the LEED reviewer flags (cross-checks SSc8 vs EAc1 ext. lighting calcs) this if inconsistency is found. Has anyone experienced a mistake like this???...and how did you resolve it???

 

Thanks,

Norbert
