energy star

EPA's ENERGY STAR Program was created to help identify the best ways to save energy. The little blue label says this product, this home, this building or factory is doing the right things to save. And offers the most comprehensive resource available for energy efficiency advice and information.

ENERGY STAR Certification

ENERGY STAR certified homes are independently verified to meet strict guidelines for energy efficiency set by the U.S. Environmental Protection Agency. These homes save money on utility bills, provide a more comfortable living environment with better indoor air quality, and help protect the environment.

Typical features to look for in ENERGY STAR certified homes include:

  • Efficient Walls and Windows, the levels of wall, floor and attic insulation properly installed designed to block drafts, and high-performance windows;
  • Efficient Air Ducts, so rooms get enough air to have consistent, comfortable temperatures throughout the house;
  • Efficient Equipment for heating, and cooling the house, helping you save money while staying comfortable;
  • Efficient Lighting and Appliances, including ENERGY STAR certified dishwashers, refrigerators, light bulbs and clothes washers.

These energy efficiency improvements not only save money, they provide a house that is warm in the winter and cool in the summer. By providing comfortable homes efficiently, homeowners are operating their homes using less power, and less resources, a green choice that continues to give back after the construction has been completed.

What comes after energy efficiency?

Homebuyers can also look for the Indoor airPLUS label — a specification developed by EPA to address the indoor environment component of green building. Homes that achieve this level of excellence are first certified as ENERGY STAR, and then also incorporate more than 60 additional home design and construction features to control moisture, chemical exposure, radon, pests, ventilation, and filtration. Together, these features help protect certified homes and their residents from mold, chemicals, combustion gases, and other airborne pollutants.

EPA's WaterSense® program helps homebuyers purchase high efficiency products that save water without sacrificing performance or quality. The WaterSense® label makes it easy for homebuyers to find and purchase water efficient products and appliances that are backed by third party, independent testing and certification. Products with the WaterSense® label perform as well if not better than their traditional counterparts and are 20 percent more water efficient on average that other products.

You can't see energy efficiency. It takes testing and expert analysis. A third party certification process makes sure anything that earns the blue label meets the highest standards. Even an LED bulb must pass dozens of checks to assure quality, performance, and efficiency. All you have to do is look for the ENERGY STAR.


The ENERGY STAR Verified HVAC Installation (ESVI) program promotes the proper design and installation of heating and cooling systems specifically for the existing homes marketplace.
