If you live in Sacramento, this is the right time for you to consider replacing your drafty windows. Installing energy-efficient windows while you are still enjoying a pleasant spring will reduce your air conditioning costs significantly when the scorching summer sets in.
What Sacramento Home Owners Need to Know About Energy-Efficient Windows
If you haven’t replaced your windows in the past decade there is a good chance that your energy bills are soaring sky-high with every passing year. This is because your windows are causing tremendous energy loss due to stationery gaps, cracked joints and crevices. Energy efficient windows will not only prevent loss of energy but also allow you to enjoy natural light without letting the heat infiltrate your rooms. Consider these 5 factors when buying energy efficient windows for your Sacramento home:
1.The Ability to Block Solar Heat
The first thing to consider when selecting any type of energy-efficient window is the solar heat gain coefficient (SHGC). The SHGC rating reveals the window’s ability to block the sunlight. A score of .57 would mean that 57% of the solar heat gets transferred to your interiors. While a higher score may be desirable during winters, a low score means a low cooling load on your HVAC system.
2.Energy Star Rating
There is a wide range of energy efficient windows available on the market, so you need to consider a design that works best for Sacramento’s climate and your home design. An energy star rating takes many factors into consideration including solar heat gain, heat loss, condensation resistance, U-factor, air leakage, sunlight transmittance, and light to solar gain. Investing in a product with the Energy Star label would ensure that you are buying a reliable and qualified product.
U-Factor is the degree of insulation offered by an energy efficient window against the outdoor temperatures. It measures the ability of the window to reflect heat and keep the cool air from leaking in a warm climate. A low U-Factor is indicative of efficient insulation and is generally measured on the glazing coat or at the center of the pane.
Certain types of glazing can significantly reduce the seepage of solar heat by controlling the transfer of warmth. Look for a Low-E (low emissivity) glazing for controlled solar heat loss and gain during warm climates. If you seek to reduce the cooling load, opt for a window with a low solar heat gain coefficient.
The light to solar gain (LSG) factor gauges the relative efficiency of glazing types in different energy-efficient windows. Apart from the LSG factor, you should also consider the acoustic performance ratings and the visible transmittance which measures the amount of light transferred through the window.
The National Fenestration Rating Council is the industry recognized for certifying energy-efficient doors and windows. An NFRC label assures you of superior performance and durability.
How Much Will You Save by Installing Energy-Efficient Windows?
A pretty good amount if you live in Sacramento!
A survey undertaken by efficient windows.org revealed that replacing a single metal frame window with a double-paned window that was glazed to have a better LSG, U-factor and a Low-E coating could save more than 15% annually on heating and cooling costs.
You need to keep in mind that your savings may vary by climate, Sacramento energy costs, and the type of window design (awning, hopper, sliding, fixed or casement) you have installed.
So get started with the installation before the blazing summer sets in and save big on your air conditioning bills this year.
