WebExperiments that involve changing the temperature of a material and measuring that change are necessarily subject to energy transfers between that material or materials and the surrounding environment. These transfers will often not be accounted for and can cause inaccuracies. If the temperatures used are within 10°C or so of the surroundings, the … WebHeat Loss Calculations. Given the R-Value and area of a section of a building envelope, it is possible to calculate the rate of heat loss by conduction (in BTUs per hour) through that section at any given temperature difference. The equation for calculating heat loss is: Heat Loss = [ (Area) x (ΔT)] / R-Value. Area = the number of square feet.
