Today I passed my LEED exam and, in a small way, I have Revit to thank. While practicing using the LEED Letter template I was amazed at how often I was able to pull up a needed site or roof area. Or if I needed totals for building materials, occupancy, plumbing fixtures, it was all at my fingertips. With a little practice with formulas in schedules, Revit Arch is a great LEED Tool.
And looking to the future, I can see Especs, Revit MEP with IES as having awesome potential. A dedicated project website like Buzzsaw would also help with the LEED process.(you might even apply for an ID point with all of the UPS and FedEX deliveries you would save!)
