• Solar Heat Gain Coefficient (SHGC): This measures the amount of solar heat that enters a room through a window. Lower SHGC values are better for warmer climates, as they reduce the amount of solar heat gain and keep your home cooler. Higher SHGC values are better for colder climates, as they allow more solar heat to enter and warm your home.
• Visible Transmittance (VT): This measures the amount of visible light that passes through a window. VT values range from 0 to 1, with higher values indicating more light transmission.
• Air Leakage (AL): This measures the amount of air that leaks through a window. Lower AL values are better, as they indicate a tighter seal and less air infiltration.
• ENERGY STAR Certification: This is a government-backed symbol of energy efficiency. To earn the ENERGY STAR label, windows must meet specific performance criteria based on climate zone. Always look for the ENERGY STAR label when shopping for energy-efficient windows. Windows labeled with ENERGY STAR are rigorously tested and meet or exceed energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA). They are designed to save energy and reduce your carbon footprint.

National Fenestration Rating Council (NFRC)

The National Fenestration Rating Council (NFRC) provides independent, third-party certification for windows, doors, and skylights. NFRC labels provide consumers with accurate and reliable information about a product’s energy performance, including U-factor, SHGC, VT, and air leakage. Always look for the NFRC label when evaluating energy-efficient windows.

Types of Energy-Efficient Windows

Different window types offer varying levels of energy efficiency. Here's a look at some of the most popular options:
