Heat Loss Gain Calculations

Heat Loss Gain Calculations. The direction of heat flow is from hot to cold, so this illustration shows conduction from a warm interior to a cooler outdoors. Notice that items 1 and 2 are directly related to the temperature of the outside air, just like their counterparts in winter heat loss calculations, but items 3, 4, 5 and 6 occur no matter what the outside temperature is.

The program cibse heat loss & heat gain (apcalc) performs heat loss and heat gain calculations according to the procedures laid down in cibse guide a (1995, 1999, 2001, 20006). How to calculate the rate of heat loss (or gain) in a building through insulation, walls, etc. Insulation (and multiple layers of glass in windows) reduces conduction losses.
