Hi! I'm trying to figure out what are the output variables that better describes HVAC electricity consumption system[Kw] for each hour. I'm using OpenStudio and my single zone model has a Packaged Rooftop Heat Pump HVAC system. It's correct to sum (Air System Total Heating Energy)+(Air System Total Cooling Energy )+(Air System Fan Electric Energy) and then convert [J] to [Kw] in order to obtain electricity consumption? Analysing my *.rdd file I also tried to obtain electricity consumption by using "Facility Total HVAC Electric Demand Power" and the results of this two "methods" are very diferent. What is the best way to obtain the HVAC electricity consumption? Thank you
