对传统度日公式中的理论和报告误差进行分析，以确定净供暖需求与度日的修正系数。然后，该系数用于隔离140个燃气供暖家庭的能源需求中炉子尺寸过大的明显影响。结果是一个更加精确的度日公式。引文:研讨会，ASHRAE交易，第87卷，第一部分，伊利诺伊州芝加哥

Analyses of theory and reported inaccuracies in the traditional degree day formula are used to develop a correction factor for net heating requirements vs. degree days. This factor is then used to isolate the apparent effect of furnace oversizing in the energy requirements of 140 gas heated homes. The result is a significantly more accurate degree day formula.
