auditoriums or rooms with high levels of internal gains. The system ends up
working overtime to displace the heat that would normally have escaped after

on a 45 degree day, the building might break even with a high internal gain and
low roof insulation, but with the higher roof insulation, the internal gains
dominate and cooling is required. It really depends on the scenario, but
