What is ENERGY STAR®
About ENERGY STAR
ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy efficient products and practices. Results are already adding up.
Americans, with the help of ENERGY STAR, have saved enough energy in a single year to avoid greenhouse gas emissions equivalent to those from 27 million cars — all while saving $16 billion on their utility bills.
New ENERGY STAR Requirements Effective January 4, 2010
Please review these new energy star requirements for the latest information and how it may affect you.
Harvey Product Qualification
Download thermal performance data for windows and patio doors that are ENERGY STAR qualified in each region. Every ENERGY STAR qualified window is independently certified to perform at levels that meet or exceed strict energy efficiency guidelines set by the U.S. Department of Energy.
Harvey Product Qualification
- Save you money and energy... Replacing with ENERGY STAR windows can save an average New England home up to $465 a year.
Estimate money and energy savings where you live »
- Find out if your energy company is offering a rebate on Harvey ENERGY STAR qualified windows, enter your zip code, and select "windows" under "home envelope".
- Make you more comfortable...ENERGY STAR qualified Harvey windows can help keep your home cooler during the summer and warmer in the winter.
- Protect your home's interior... Many ENERGY STAR qualified windows act like sunscreen for your house, protecting your photographs, artwork, furniture, carpets and wood floors from damaging ultraviolet light without noticeably reducing visible light.
- Help the environment... ENERGY STAR qualified windows lower your energy use, which means less air pollution from power plants.
Note: In order for homeowners to receive any rebates, NFRC labels must remain on the windows until a gas/utility company representative inspects the windows. Some rebates may require a manufacturing order number, which can be found on the Harvey warranty label.
Performance Ratings (from ENERGY STAR)
The NFRC label, which can be found on all ENERGY STAR qualified windows, provides performance ratings in a number of categories:
- U-Factor measures how well a product prevents heat from escaping a home or building. U-factor ratings generally fall between 0.20 and 1.20. The lower the U-factor, the better a product is at keeping heat in. U-factor is particularly important during the winter heating season. Find the ENERGY STAR U-Factor for your region.
- Solar Heat Gain Coefficient (SHGC) measures how well a product blocks heat from the sun. SHGC is expressed as a number between 0 and 1. The lower the SHGC, the better a product is at blocking unwanted heat gain. Blocking solar heat gain is particularly important during the summer cooling season. Find the ENERGY STAR SHGC for your region.
- Visible Transmittance (VT) measures how much light comes through a product. VT is expressed as a number between 0 and 1. The higher the VT, the higher the potential for daylighting.
