Okay, maybe I'm being harsh again but it's really simple math and I ... and in heating when the heat is non-electric. Remember, lights give off heat and therefore increase the amount ...

eQUEST for LEED Case Study - Part 3

with separate HVAC system. Well interestingly enough we have two systems. However one of them is a heat pump which we need to get rid of because this says nothing about heat pumps. So remember that; the number ... have two systems, but one of them is a heat pump which we need to get rid of because this says nothing ...
