A COMPARISON OF SEVEN BASEMENT HEAT LOSS CALCULATION METHODS SUITABLE FOR VARIABLE-BASE DEGREE-DAY CALCULATIONS.

Author(s) : MACDONALD G. R., CLARIDGE D. E., OATMAN P. A.

Summary

SEVEN HEAT LOSS CALCULATION METHODS ARE APPLIED TO A PROTOTYPICAL BASEMENT IN FIVE US CITIES. EACH METHOD AND ITS LIMITATIONS ARE BRIEFLY DESCRIBED. THEIR SENSITIVITY TO BASEMENT DEPTH, INSULATION R-VALUE, AND SOIL CONDUCTIVITY IS ALSO INVESTIGATED. PREDICTED ANNUAL ENERGY LOSS VARIES BY MORE THAN A FACTOR OF 2 IN SPITE OF CLAIMS OF INSTRUMENTED FIELD VERIFICATION FOR MOST METHODS. WHEN WALL LOSS IS CONSIDERED SEPARATELY, THE AGREEMENT IS MUCH BETTER. IT IS CONCLUDED THAT THERE IS PRESENTLY NO STANDARD AGAINST WHICH TO MEASURE THE ACCURACY OF ANY BASEMENT HEAT LOSS METHOD.
