These figures show that 6.6% more kwh are required to heat the conventional structure. Using a vapor-proof building paper with R = 0.08 would lower the U value for a stone structure to 6.21 x 10-2 BTU/hr ft 2 °F. The kwh lost in this case would be 982 and the wood structure would require 7.1% more energy to heat than to the stone structure.
