[Equest-users] Here is a real knuckle ball

[Brian Fountain]

I am not seeing what you are seeing.  With no lighting, space heat is 239,761 kWh.  With lighting,  space heating is 174,860 kWh. Cooling is also behind as I would expect ... more with lighting. 

I think your lighting schedule is dramatically too big for apartments. It ranges from 60% overnight all night to high 80s all day. I wouldn't expect more than 3 to 4 hours of lighting for apartments.
