It is crucial to your home’s energy bills and energy efficiency that
you become familiar with certain terms, such as air leakage and U-factor.
These terms can inform on your next replacement window choice, which could
severely impact your energy costs. Continue reading to
learn more about these energy efficiency terms.
Air leakage is one of the most important factors to keeping your home energy
efficient and reduce your energy bills. If a window has a high air leakage
value, then it is likelier to allow air to pass in and out of your home.
This air leakage can cause your heating and cooling bills to increase,
due to the HVAC unit’s need to work harder to heat or cool your
home. Look for windows with a low air leakage value and quality window
installations to ensure the least amount of air can leak through.
Solar Heat Gain Coefficient
Solar Heat Gain Coefficient, also known as SHGC, is another important contributor
to your home’s energy efficiency. SHGC measures how well a window
will block the sun’s heat. Lower SHGC numbers indicate that less
solar heat is transmitted through the window. This will also reduce your
cooling costs by reducing the amount of heat entering your home.
U-factor relates to a window’s insulation properties, which also
reduces the amount of hot or cool air that transfers through a window.
The U-factor value should be as low as possible to receive the best energy
efficient and insulated window.
Visible transmittance refers to how much light filters through a window.
This is an important term, because it can determine how much fading or
sun damage might occur on interior floors, window treatments, and furnishings.
The lower the visible transmittance value, then less light will enter
