I am not sure what any of the formulas involve in an LEED building, but it seems like a joke to me. I am an elecrician and am working on my first LEED building and I can see NO energy effeciancy steps taken anywhere. There are no timers or motion sensors to control lighting in the building at all, there are quite a few incandecent light bulbs, they use underground hot water to melt snow for a HUGE area outside (including the road). I have not seen this level of ineffeciancy in at least a decade.
