The language of The Reference Guide and MPR's don't seem to quite come out and make this clear; so I figured I would just ask - - suppose a company owns a building, lives and works in that building, and subleases one floor of it......can they use LEED CI for the floors they occupy? Can they "ignore" energy and atmosphere pre-req's like HVAC system or building envelope minimum efficiency (ASHRAE 90.1)? Thank you.
