CI-2009 EAc1.1:Optimize Energy Performance—Lighting Power

Building Area vs Space-by-Space method

We are working on a LEED-CI project in a large commercial office building, where the overall 'building area' method would clearly be office at 1 W/sf. The tenant space we're doing is very small relative to the overall building, and consists primarily of a cafe and seating area with a small conference room. Thus, the majority of our scope is dining, which would be 1.4 W/sf. Does anyone have a recommendation whether we may apply the building area method based on our individual tenant space, rather than based on the overall building itself? Thanks in advance.

Hi Brian, We have LEED-CI Café projects within office buildings. We use the space by space method and reflect the use in the tenant space, i.e., dining, reception, fitness, etc.

Thanks! We're leaning towards space-by-space because there shouldn't be any gray area there. We were just wondering if there would be an opportunity to use the building area method, classifying the tenant space as "dining" instead of "office", as this would result in more points in our case.

Hi Brian, I can see the appeal in the higher allowance and obviously the next point threshold. But given the small conference room, I would hesitate to do that. However, if you are a gambler and don't "need" the extra point, and the overwhelming majority of the tenant space is café, you could attempt it and see what the reviewer says. Worst case they'd just tell you to use the other method. Good luck.
