Hello everybody, I am fairly new to the world of energy simulation but I was charged with a hard task. Basically I need to simulate an hospital building (15 floor total, 53.000 m^2 surface). I have created the 3d model with sketchup and assigned a very simple thermal zoning (1 floor= 1 zone). I have also begun to connect the HVAC systems, which are (for the moment) only 2 VAV with reheat. I modified the two system to have, on the hot water side loop, district heating as heat source. The chilled water loop is made by an absoption chiller linked to a simple condensing tower. The simulation runs smoothly except for some shading surface warnings (which I will adress later). The problem is that I have a lot of unmet hours during both cooling and heating. I think this could depend from the setpoint manager I have chosen. I selected a min max with deadband for both the VAV system, slightly modifying the standard schedules automatically created by openstudio. Can anybody help me adress the problem? I am sorry for my poor english.
Ps: what files shall I attach to the message to help adress the problem?
Thanks
