Hi All, I am trying to model heated floor for my overhang floors (external floors). I am receiving the error of ''having a heated floor but no floor surfaces in the zone have an internal source set in their Construction'' while I am pretty sure (checked several time) all zones that I am adding heate...

Small change leads to huge difference in simulation duration

I am working on a big size building model that usually takes about 3 hr of simulation to get annual results. recently I added extra water heater (radiator) to some of the group zones to solve my setpoint not met hours. These extra heaters changed my simulation duration to 14 hr !!!! I reviewed big s...

Multiple buildings with central boiler and chiller

I am working on modeling a campus with multiple buildings that has a central boiler and chiller in one of the building. Central boiler and chiller provide HW and CHW for all the buildings. I created models for each building separately with district heating and cooling plant. However, I am not sure h...
