What is it? Created by the Environmental Protection Agency (EPA) to promote energy efficiency, an ENERGY STAR certified home will perform at least 10% more efficiently than a code-built home, and often 20% more efficiently. In order to achieve this level of performance, homes are built using more efficient systems and materials — including windows and doors.
What are the key principles? There are various paths that can be taken to achieve the level of efficiency ENERGY STAR certification requires, but generally this approach emphasizes:
- A tight building envelope with enhanced insulation and air sealing
- Efficient HVAC systems
- ENERGY STAR certified appliances, lighting, windows, and doors
What role do windows and doors play? This program requires windows and doors to meet specific performance criteria, including specific U-Factor and Solar Heat Gain Coefficient (SHGC) measures. The exact performance required will depend on the climate zone — understand more about ENERGY STAR performance criteria.
How can you get the certification? Both new and existing homes can be ENERGY STAR certified. The process involves having an ENERGY STAR Certified Builder, a certification that is very easy to obtain, and a third-party verifier certify the home. Most third-party certifications will be conducted by a home certification organization (HCO). There are two nationally recognized HCOs, Residential Energy Services Network (RESNET) and Building Science Institute (BSI). The builder will work with an HCO, beginning during the planning stage, to achieve certification. ENERGY STAR has different programs, including programs for single-family, multi-family, and manufactured homes.
Other benefits? If you’re a builder, what do you get out of having a home ENERGY STAR certified? You may qualify for the 45L Tax Credit, a federal tax credit of up to $2,500. Find more information on the ENERGY STAR website.
