能源部的季节能效比规定提供了一种方法，用于比较使用各种方法实现高效率的系统的季节效率。对这些法规进行了详细审查，并与实现不同效率水平的成本研究一起使用，以确定实现这些季节性效率水平的最具成本效益的方法。此外，还对多个地点的不同效率水平的运营节约进行了检查，并将其与实现不同效率水平的成本进行了比较，以确定高效率在经济上是合理的。 引文:研讨会，ASHRAE交易，第86卷，第一部分，加利福尼亚州洛杉矶

The Department of Energy Seasonal Energy Efficiency Ratio regulations provide a method of comparing the seasonal efficiency of systems using various approaches to achieve high efficiency. These regulations are examined in detail and used with a study of the costs to achieve different levels of efficiency to determine the most cost effective approach to achieve those levels of seasonal efficiency. Also, operating savings with various levels of efficiency for several locations are examined and compared to the costs of achieving the various levels of effi­ciency in order to determine where high levels of efficiency are economically justifiable.
