BARRIERS OR ATTIC INSULATION

WORKSHEET

COST OF ENERGY FOR HEATING AND COOLING

Code: (A)	(B)	(C)	(D)	(E)	(F)
Cooling Equipment Efficiency (From Table X)	Heating Equipment Efficiency (From Table X)	Cooling Fuel Price $/Million BTU	Heating Fuel Price $/Million BTU	Cooling Energy Cost $/Million BTU [C÷A]	Heating Energy Cost $/Million BTU [D÷B]

For fuel prices:

Electricity: $/million BTU = ¢/KWH x 2.93
Natural Gas: $/million BTU = ($/therm or $/CCF) x 10
Fuel Oil: $/million BTU = $/gal. x 7.15
