Hi there:

I meet a strange simulation result. The project is is 6000 SQM warehouse plus a 1000 SQM office. The result shows a surprising natural gas usage 84581 MBTU or 89237 GJ. 96% belongs to space heating.

REPORT- LS-C BuiLding Peak Load Components shows heating load 32.5 W/m2 (excluding outside ventilation air loads). This is normal.

REPORT- SS-D Building HVAC Load Summary shows annual heating energy 1460 MBTU or 1540 GJ.

Is there anywhere else to check the source of the extra abnormal space heating load?

THX!
