Home Energy Score

DefinitionThe Home Energy Score, managed by the US DOE, is a national system that allows homes to receive an energy efficiency rating, similar to the MPG rating available for cars. The Home Energy Score uses a 10-point scale to reflect how much energy a home is expected to use under standard operating conditions. Homes that are expected to use the least amount of energy (and are considered the most energy efficient) score a 10, and homes that are expected to use the most amount of energy (and are considered the least energy efficient) score a 1. The Home Energy Score uses a standard calculation method and takes into account the home's structure and envelope (walls, windows, foundation) and its heating, cooling, and hot water systems. Only Qualified Assessors who pass a DOE exam are allowed to provide the Home Energy Score.
