The answer to whether energy efficient windows make a difference can be found in the question, itself. It is a pretty well-known fact that homes lose most of their energy through their windows and doors. Windows that do not have energy efficient treatments on them can waste up to a whopping 50% of a home’s heating and cooling-related energy. When it comes to Ann Arbor and the surrounding areas, in particular, this is particularly important.
As some of us know, glass is not a great insulator. As a result, a lot of heat will escape through them in the winter while in the summertime, outside heat will radiate inside. But with energy efficient window treatments, this process is greatly reduced, also reducing your overall energy consumption, save you on your utility bills and provide for a more comfortable, indoor atmosphere.
What to Look for in Energy Efficient Windows?
Energy efficient windows need to comply with your local energy code. You should look for models that have an ENERGY STAR certification as these often meet or even exceed local requirements. To determine whether any specific window complies with your local requirements, check its National Fenestration Rating Council (NFRC) label. It will display the window’s energy properties as follows:
U-Factor – This rates the heat loss of the non-solar heat loss. The lower this number, the higher it’s insulating value.
Solar Heat Gain Coefficient (SHGC) – The SHGC is the fraction of incident solar radiation that passes through the window. The lower this coefficient is, the less solar heat it transmits. Depending on the climate, the house-window orientation, shade, etc., a higher or lower SHGC is desirable.
Visible Transmittance (VT) – The VT measures the amount of daylight that enters your home. The higher the number, the more light is realized. It will save you on your lighting bills.
Air Leakage (AL) – The air leakage is expressed in cubic feet and represents the amount of air passing through the window area. It means that with a low AL, less air will pass through the cracks.
Condensation Resistance (CR) – CR represents how well as particular window will resist the formation of condensation on its surface. The higher the number, the better.
The Benefits of Energy Efficient Windows
Like we’ve mentioned in the beginning, energy efficient windows will play a significant role in mitigating unwanted heat loss in winter and will keep your home cooler in summer. It also means that there will be less strain on your HVAC system, increasing their lifespan. These windows will also allow you to take full advantage of daylight, without having to turn on the light prematurely.
They will also increase the comfort of your home. In winter, for instance, the traditional glass surface cools significantly, creating uncomfortable drafts around the room. It will no longer be the case with energy efficient windows. It’s also good to take into account the condensation level. As the interior surface of these windows is much higher than other windows, condensation is substantially reduced or even eliminated.
They can also reduce the amount of UV radiation that comes into the home, thus increasing the life of your fabrics and furnishings. Last but not least, these windows will also decrease the amount of noise coming from the outside, making your home even more comfortable, in the process.
