WebJun 24, 2024 · Energy enters all ecosystems as sunlight and is gradually lost as heat back into the environment. However, before energy flows out of the ecosystem as heat, it flows between organisms in a process called energy flow. 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.
