A simplified calculation method has been developed for predicting: 1) maximum rate of heat loss from a basement; 2) the basement total heat loss over the heating season. This method differs from previous ones mainly because it recognizes the annual variation of basement heat loss as a significant component of the total basement heat loss. The development of the method is based on both experimental and analytical studies of basement heat loss. The essential data needed to calculate the basement heat loss are the steady-state and periodic shape factors, the amplitude attenuation factor and the time-lag factor and ground surface temperatures. The basement heat loss factors for several insulation systems as well as the ground temperature data for several locations in Canada are listed in the paper. A comparison of the calculated and measured basement heat loss values indicate that the method is capable of reasonably accurate prediction of basement heat loss. |
