This calculator is using weather that is representative of the Vancouver, WA area.
All calculations are estimates. Energy costs for your home are an estimated starting point from which you can compare potential energy-saving measures. Your actual energy bill will be different from these estimates because this tool does not use your actual billing history. The calculator uses actual weather and energy costs in your area. However, actual energy costs and savings are also affected by factors such as lifestyles and personal behaviors that are not considered by the Home Energy Calculator.

This calculator will provide you with estimates of energy use costs based on your inputs. The Annual and Monthly results are not intended to be extremely accurate, but rather, to provide a comparison platform to give you the differences between the energy your home is currently using ("Base House") versus various "Scenario" variations. After you run a few variations, be sure to click the View Annual and View Monthly buttons for different views. To go back to view the details of a "Scenario" variation, click on its number.
