[BLDG-SIM] Exterior Ltg & LEED EA Credit 1

[Fred Porter]

I'm confused as to whether any exterior lighting power can differ
between the proposed & baseline models. Any one have any experience from
EA Cr1 submissions?

 

The Users Manual for App G states at the end of the "Baseline Lighting"
Section, "…. credit may be taken for improvements in exterior lighting
efficacy or wattage… the proposed building can take credit for a more
efficient system." So proposed parking lot lighting at 0.08 W/sf or
whatever would be compared to a baseline of parking lot lighting at 0.15
W/sf. I believe façade lighting must be the same in both, as these are
"non-tradable surfaces" in Chapter Six.

 

But an apparently poorly-considered Credit Ruling from 4/25/07 simply
states "No. Appendix G does not allow trade-offs for exterior lighting,"
directly contradicting the UM.

 

Perhaps a post like this should be on the USGBC "engineers"
"member-to-member" forum, but I don't see much traffic there.
