Revision history [back]

It's been a while since you posted this, so maybe you figured it out already. But for the record, there are several things contributing to no heating load in many zones.

1. GroundTemperatures are all 22C. This is quite warm.
2. There is no infiltration.
3. Lights and electric equipment are using normal weekday schedules for WinterDesignDay - suggest using the holiday day schedules for WinterDesignDay.
4. Thermal Zone 10, for example, has no exterior surfaces, so I would not expect a design heating load for this zone.
