ENERGY STAR is the symbol for energy efficiency, as designated by the U.S. Department of Energy (DOE) and the U.S. Environmental Protection Agency (EPA). In addition to homes, the ENERGY STAR label can be found on energy-efficient electronics and appliances.

ENERGY STAR Home Sealing Initiative for Existing Homes

In November, 2001 ENERGY STAR launched a new building envelope improvement initiative called "ENERGY STAR Home Sealing" intended for homeowners considering improvements to their home.

ENERGY STAR Home Sealing is designed to give homeowners a clear set of recommendations on how they can improve their home's envelope using a building systems approach. The initiative recommends that homeowners add insulation where cost effective and seal air leaks to stop drafts and get the full performance out of their insulation. In addition, homeowners should choose ENERGY STAR labeled windows when replacing old windows to save energy and money.

For "handy" homeowners, there are several "do-it-yourself" measures that the Home Sealing initiative suggests, such as caulking and weather stripping doors and windows and adding insulation to the attic. However, for optimum results, ENERGY STAR recommends that homeowners seek the assistance of a home energy professional and/or contractor in their area to conduct initial diagnostic tests, make the upgrades, and perform combustion safety testing after air sealing work is completed.
