An introduction to window energy efficiency and cost savings in Southern California.

Did you know that 10 to 25% of the energy you use to heat or cool your Anaheim home is lost through your inefficient windows?

This is because the windows in your Anaheim home can let out up to 48% of your homes much-needed heat in winter and let in up to 87% of your homes unwanted heat in summer, raising your energy costs.

Will replacing your windows really help you save energy and money?

The answer is YES. According to Energy Star upgrading old single pane windows to more energy-efficient units can help your household save $126 to $465 dollars per year. Your exact savings in Anaheim, California will depend on local energy costs, home orientation and construction, and your windows energy efficiency ratings.

Do you understand energy efficiency ratings?

Window efficiency is measured by these important ratings:
1. The U factor is a measure of how well a window prevents heat from escaping your home. The lower the number the better.
2. The solar heat gain coefficient is a measure of how much of the sun’s heat is blocked by a window. The lower the number the less heat that comes through the glass.
3. Visible transmittance is a measure of how much light a window lets in. The higher the number the more light that can come in.
4. Air leakage is a measure of how much air a window lets in. The lower the number the better. 5. Condensation resistance is a measure of how well a window resists the formation of condensation on the inside surface. The higher the number the better.
