Home Performance With ENERGY STAR® Program
Typical Improvements in a Whole-House Approach
Your Home Performance with ENERGY STAR contractor might recommend any of these typical energy-saving home improvements:
Sealing air leaks and adding insulation
Sealed air leaks and properly installed insulation in attics, walls and floors allow more even temperatures throughout the home and result in a quieter, more comfortable and less costly living environment.
Ensuring adequate ventilation
Ventilation, or the exchange of indoor air with outdoor air, is critical to reducing indoor air pollutants, moisture and odors in your home. Without proper ventilation, contaminants such as formaldehyde or other volatile organic compounds (VOCs), and radon can cause health problems, while excess moisture can lead to mold growth and physical damage to your home.
To ensure the health and safety of the occupants, the program requires mechanical ventilation to be installed as deemed appropriate by your participating contractor. To learn more, see the U.S. Department of Energy's overview of whole-house ventilation and the National Renewable Energy Laboratory’s fact sheet on whole-house ventilation systems.
Sealing and insulating ductwork
Sealed ducts and a balanced duct system can optimize airflow to all rooms. Insulating ductwork in attics and crawlspaces can also reduce energy use.
Improving heating and cooling systems
Properly installed ENERGY STAR qualified high-efficiency heat pumps, furnaces and air conditioning units can help you save on heating and cooling costs year-round, and also provide more consistent temperatures and humidity control.
Upgrading lighting, appliances and water heating equipment
Energy used for lighting and appliances can account for nearly half your utility bill. Installing ENERGY STAR qualified products recommended by your Home Performance with ENERGY STAR contractor can help you reduce the energy used, helping to lower your utility costs.
ENERGY STAR qualified window models that are specific to your local climate will help insulate your home from outdoor temperature changes, eliminate drafts and lower your energy costs.
