House Energy Footprint

How energy efficient is your house?

This page calculates a measure of energy consumption based on climate. It takes all the energy bought for the house, and divides it by the sum of the heating and cooling degree days. It gives a feeling for energy consumed as related to climactic need. It is basically the building heat-loss factor with all energy considered as heating energy.

All values should be for an entire year, or the average per year of several years. BTUs and pounds of CO₂ will be calculated, no need to fill in. This calculator uses javascript, so will need to have that turned on (sorry!).

I do not save any of this information, however if you would like to send me your results, I would appreciate it. If you would like I can display your results on the left hand column.
