<p>Hey there Home Energy Pros,</p>
<p>How do you calculate whole home heat loss from the ducts? To put this in context, I know how to calculate heat loss from the envelope (walls, floor, ceiling taking into consideration insulation levels and air leakage) but I am stumped on how to calculate how much heat the home is losing through ducts located outside the thermal envelope. A little help, please?</p>
