Above is a 6 minute video tutorial demonstrating how to setup the Energy Data properties for the REVIT MEP project. Once this is done you can use the awesome Heating and Cooling Load calculations API provided by IES to create the report.
From there we apply those loads to our mechanical system and start to layout the physical model.
We specify the 'Building type' and the 'Building Construction (assembly) types' to further enhance the accuracy of the energy analysis. See images below.
