Heat flow through wall
Web2.4.1 Calculating the total heat loss of a house. If we know the U-values of all the elements of the external fabric of a building, its volume and its average ventilation rate, then we can calculate its overall heat loss coefficient (or heat transfer coefficient). We can define this as the total space heating energy flow rate in watts divided by the temperature difference … Webin this video derive the expression for heat flow rate of composite wall.
