A simplified methodology for accurately calculating building heating loads, termed the Modified Bin Method is developed and validated. The method is reliable and accurate and combines the simplicity of hand calculations with the accuracy of computer simulations to provide a substantial improvement over the conventional simple degree day and bin methods and the high cost of sophisticated hourly simulations. The Modified Bin Method uses standard steady-state equations for envelope heat loss and heat gain is developed using multiple regression techniques based upon a statistical analysis of fifty-one computer simulations of test buildings. Example calculations using this method estimate annual building heating loads to within 1.5 of the results of an accurate computer simulation at a small fraction of the time and expense. Author
