3. Building Size

A caller to my Saturday morning radio program asked my how he might make his new 4000 sq. ft. home more energy efficient. I blurted out that he might consider building a 2000 sq. ft. home. My answer was not very polite - but it was valid. Larger homes take more energy to heat, light and use than smaller homes. We may argue about the relative energy budget of a 2000 sq. ft. home vs. that of a home twice the size, but there is no doubt that the bigger home will use more energy than a similar smaller home. Monster houses have monster energy budgets!
