We are working on a LEED 2009 NC project and looking at the daylighting.

Hello! We are pursuing LEED NC 2009. Our project is a Data center office building which will be operated 24 hours, 365 days per year, with No transients, visitors or residents in the building.

The selling area of a retail commercial interior project will be a conditioned space located over a parking area whose height is half under sidewalk level and half above it.

I am an architect who has been building super sustainable houses since well before LEED existed.
