<div style="RIGHT: auto"><SPAN style="RIGHT: auto">Turning a file you used for load calculation and equipment sizing into an energy model is not a quick thing. Having the loads done is not half way. You now need to make schedules for lighting, equipment & people, get the 8760 weather file, find out energy cost in the area, input equipment information and a few more quick things as indicated in ASHRAE 90.1.</SPAN></div>
