Is exterior lighting included?

We have a restaurant project (LEED for Retail: CI) in which the tenant has a open space. There is a canopy outside used for retail purposes and obviously some exterior lighting. Should we include the exterior lighting in this credit? If yes, which method should we use? Thank you in advance.

I don't think you would inlcude exterior lighting. As a CI project I think the assumption is that the project only inlcudes interior space. Are you including this exterior space for other credits? If you are, then I suppose you could just treat it as an interior space. you woudl sue whatever method (space-by-space or building area) that you are using on the interior. Or use the exterior LPD limits in 90.1-2007 (table 9.4.5). But CI EA 1.1 makes no provison for this in the credit langauge or the submittal template.

You're right. We didn't add exterior lighting into credit calculations, but we showed that it is less than exterior LPD limits. Our credit has been accepted by the review team. I think this is the most convenient way since the project is subscribed as CI.
