What is the easiest way to determine the heating energy required for a particular zone or building? I have a boiler system that feeds the hot water loop feeding multiple buildings and I want to know how much energy the boiler is using to meet the heating loads of a single particular building. I have tried to use separate fuel meters for the zones in that particular building...but the output reports come back with no energy reading on these meters. I believe this is because the boiler (that feeds all the buildings) is assigned to only one meter. How can I get the information I need without assigning a boiler, pumps, and hot water loop for each building? Thanks so much for your help.
