Heat gain through walls
WebThe total fabric heat loss flow rate, Q f, will be the sum of all the U -values of the individual elements of the external fabric, walls, roof, floor, windows and doors multiplied by their respective areas multiplied by the inside–outside temperature difference, Δ T. Q f = (Σ U xA x ) × Δ T watts - (note: the Σ symbol means ‘sum of’)
