[Equest-users] negative energy savings for infiltration reduction?

Hi Steve:
 
I am just guessing, but when you tighten a building up from air, you tend to lose (in my experience) any "free cooling" you may have had from a leaky building in cooling months.

When modeling infiltration (ACH) reduction in equest, I often get smal negative electricity (cooling) savings and large positive heating savings. This can occur even when air sealing is accompanied by insulation( spray foam) for multifamily buildings in NJ and PA.

Do other people see this? IS there any explanation for this? or is a bug?
