This question is in regards in to LEED CI 2009 - Credits EAc1.1 & EAc1.2 for lighting power density and light controls.

Do tenants have to account for common areas and spaces for lighting power density and light controls credits? Such spaces include elevator lobbies and common lobbies. A specific example would be when there are two separate tenant spaces on the floor and the elevator lobby and general lobby are a shared space. Or does this come down to the lease agreement and the spaces it entails?

Thanks in advance for the help!
