Step 5: Install energy saving windows
Energy is lost through windows while heating and cooling interior spaces. Double-paned windows can save energy and money. Energy Star labeled windows are twice as energy efficient as the average 10 year old window. They can reduce energy bills by up to 15% in hot and cold weather. The cost for an average window size is in the range of $600 and $850 or approximately $0.50 per square foot. The following are some tips for investing in energy saving windows.
Tip 1: Invest in Energy Star Labeled windows.
Tip 2: Look for the window performance, as certified by National Fenestration Rating, as per climate conditions.
Tip 3: For colder climate, a rating value of 0.35 or below is recommended by EERE.
Tip 4: For warm climates, look for doubled glazed windows and spectrally selective coating.
Tip 5: Choose windows with 0.3 cubic feet per minute or less of air leakage rating.
Tip 6: For locations with heating and cooling seasons, select windows with low U-values and low Solar Heat Gain Co-efficiency.
Tip 7: In order to install the windows correctly, choose qualified and reputed window installer.
