CH-81-03-3 -- Comparison of DOE-2-Generated Residential Design Energy Budgets with Those Calculated by the Degree-Day and Bin Methods PDF

Residential design energy budgets for the building energy performance standards were generated by the use of the DOE-2 computer program for four different types of structure in 10 different localities throughout the U.S. The DOE-2 calculations for these conditions were repeated by simplified procedures using the degree-day and bin methods. By modifying the basis for the degree-day data from 65°F to building specific value, remarkably close agreements were obtained between the DOE-2 and the degree-day results. Also, good agreements were obtained between the DOE-2 results and the ASHRAE TC 4.7 bin method.
