Only natural gas consumption in February?

Hello,
I am doing an energy simulation for our College's church for some energy efficiency retrofits.
I can't figure out why my energy simulation is only using natural gas in February in the Building Creation Wizard (simplified version). The actual natural gas usage of the building I am trying to model is much higher. I have been trying all day to tweak various items, but still only shows consumption for February. The electricity usage (in kWh), however, is very accurate.

What am I doing wrong/overlooking?

Thank you,
Claire Naisby

At first glance, I would say it is because:

1) All spaces are underground, and the wall and floor construction has
a pretty good insulation value.

2) There is no outside air scheduled at all

3) Whenever the space is occupied, there is a decent amount of lighting
and power to help with any internal heating requirements

I changed the OA to 17 CFM / person, and heating went up dramatically.
