How Was the Home Energy Score Created?

The energy score program was developed using a formula developed by the U.S. Department of Energy to calculate the energy use of a residence. During an energy audit, every room in your home is measured and given a number on a scale of 1 to 10, with 10 being the highest efficiency. The average rating for an energy audit is usually around 5. This report considers the amount of energy used in your home as well as the anticipated cost of energy. The score provides a list of tasks for home renovation you can decide to move forward with and that can be finished in ten years or less. Evaluations can also be used to rank projects for residential clients in order of associated costs.
