At an air change rate of n = 1 h1 for ventilation and leakage together (i.e., all the air in the building is, on the average, renewed once every hour), the ventilation heat loss is: At a volume, V = 125 m3; air density, = 1.2 kg/m3; specific heat capacity of air at constant pressure, cp = 1000 J/(kgK); and a temperature difference of 20 K, the ventilation heat loss becomes: This is of the same order as the transmission heat loss estimated at 1000 W. If only a small portion of the air change is caused by leakage, exhaust air heat recovery may reduce this loss.
