The calculation method requires that the volume of each room be calculated; then the rate of heat loss at the design temperature is calculated using the formula:

Cool roofs are not for high-slope roofs in cool climates by Dana Dorsett. Using a high solar reflectivity/moderate deep IR emissivity approach the steady state and peak roof temperatures under summer sun can can be brought down considerably, and even in a well insulated attic the roof can be a large fraction of the cooling load.
