Even if you don't want to heat the space, it's still going to have a
heat loss if there is a colder space below, above, or next door. I'm
guessing your space is over a cooler space that isn't heated or at least
not heated as warm as your space of interest. So naturally you would
have a heat loss, but get a cooling credit.
