Wrong temperature outputs

Hi dear all, This is a residential modelling using OpenStuido / DesignBuilder / and EnergyPlus software with and without auxiliary solar loop. The HVAC design consists of an AHU system in which heating is supplied through two different methods One using electric heating coils and next using water heater coils connecting to a boiler. Moreover, cooling is supplied through electrical cooling system.The files run completely without any errors. However, the temperature results of simulation, more specifically for the zone mean temperatures exceed the corresponding temperature set points for each zone that seems outputs are not correct. I would appreciate it if you could help me to solve this problem and tell me have I used the correct component for this modeling, like heat exchanger an so on? Cheers, Kamran

Without seeing the complete idf file, this is only a wild guess, but the problem is likely in the SetpointManager controls for the AHU. It is likely that you need to use SetpointManager:SingleZone:Cooling (and Heating) to control the AHU coils to meet the current zone load. If that doesn't help, then we'll need to full idf file, please post a link here or sent to and reference this unmethours question.

Could be a value with the material properties in the walls, ceiling or roof configurations, i recommend specifically check the interior and exterior layers and the adiabatic surfaces
