Revision history [back]

As @Julien Marrec commented if your building doesn't have any mechanical system to deal with the energy you gain inside your building it make sense that your building temperature will rise. Other factor might be sun radiation penetrating the space through the windows. As mentioned before you should set realistic air infiltration which might reduce the load inside your building.

Generally I would recommend on doing the following:

1. Assign proper infiltration rates.
2. Assign Heating and Cooling thermostat schedule for each zone (and maybe Humidistat if needed).
3. Assign ideal load air system to the different zones.
4. After running the model make sure the load for each zone make sense.
