[Bldg-sim] Incorrect information in TMY file

I've gotten a few responses saying that the elevations are in meters.  The altitude correction factor that eQUEST uses is 1.06, which corresponds to an altitude of about 1,600 feet.  Any thoughts on how to a) notify eQUEST that the elevation is in meters, or b) modify the elevation in the bin file?
