Quick post today. We had a question on the Autodesk Revit MEP forum this morning, that I thought I'd share with all of you. The user wanted to sum the individual Heating and Cooling Load values for the Volumes in his model, in order to get the Total Building Load. That's not the best way to calculate that value, so I went ahead and provided an explanation of how we do it in Revit MEP 2009.
Check it out.
