参考答案: D

本题解释:
Reference: Energy and Atmosphere Credit, Optimize Energy Performance-Equipment and Appliances

Percentages are based on power demand (rated power). At least 70% of eligible equipment must be ENERGY STAR qualified. The number of appliances isn\'t used as a percentage because different brands/models of an appliance may have different energy needs. For example having 3 ENERGY STAR qualified refrigerators out of a possible 4 refrigerators would seem like a 75% achievement. That is incorrect. The rated power of all 4 units is compared to the power that is ENERGY STAR for the 4 units.
