As much as 81% of heat gain in the summer takes place through the ceiling and roof. Reflective insulation reflects the sun’s heat before it can penetrate your home. You will use less air conditioning to keep your home comfortable all summer long. According to the Department of Energy, homeowners can expect up to 16% cooling savings depending on climate, current amount of insulation in the attic, and household energy use. Many EnerG Shield customers claim to have seen even higher results, but these results have not been scientifically verified by a third party.
Minimize ceiling and attic heat loss during the winter by upgrading your insulation.
Just as your ceiling and roof retain heat during the summer, they release heat during the winter as the hot air rises and escapes through your roof.
As you run your furnace during the winter to heat your home, reflective insulation in your attic reflects that heat right back into your home. You spend less money on heating while staying warm and comfortable.
Boost your home's insulation with solar window film.
Block the sun – not your view – with energy-saving solar window film.
The home cooling and energy saving potential of solar window film is exceptional.
Fabricated using ceramic nanotechnology, window film effectively reduces the movement of heat entering or leaving your home. It eliminates hot and cold spots in your home or commercial building.
Increase your home's air circulation with Solar Attic Fans.
Consider using solar attic fans along with your air conditioner to increase your home comfort. They can lower your energy bills and extend the life of your air conditioner. When your attic temperatures rise in the summer, proper ventilation can reduce those high temperatures by up to 50°F. With an attic fan you can be just as comfortable with the thermostat set to 78 degrees as you would with air conditioning alone set to 72 degrees. For each degree you raise the thermostat, you save you 3-5% on air conditioning costs.
Weatherize to prevent phantom air leaks.
Have you ever noticed how certain rooms in your home feel drafty? As it settles into its foundation, almost every home experiences air leaks. In fact, the average house—even when well-insulated—contains cracks and gaps between building materials that add up to a hole about 14 inches square.
Look for these energy-wasting leaks around the gaskets on your exterior wall outlets and switches, doors and windows, exterior cracks, chimneys, close dryer vents and built-in air conditioners.
Upgrade your windows.
Windows can be one of your home’s most attractive features. Windows provide views, daylighting, ventilation, and solar heating in the winter. Unfortunately, they can also account for 10% to 25% of your heating bill. During the summer, your air conditioner works harder to cool hot air from sunny windows. Install energy-saving double-paned windows and solar window shades to give your air conditioner and energy bill a break. If you live in the Sun Belt, look into low-e windows, which can cut the cooling load by 10% to 15%.
Maintain your heating and cooling system.
No matter what kind of heating, ventilation, and air-conditioning system you have in your house, you can save money and increase your comfort by properly maintaining and upgrading your equipment. But remember, an energy-efficient furnace alone will not have as great an impact on your energy bills as employing a more holistic approach. According to the U.S. Department of Energy, by combining proper equipment maintenance and upgrades with appropriate insulation, air sealing, and thermostat settings, you can cut your energy use for heating and cooling, as well as reduce environmental emissions, anywhere from 20% to 50%.
Replace incandescent with CFL (Compact Fluorescent Light) bulbs.
In addition to the significant energy savings CFL bulbs provide while lighting your home, they also produce virtually no heat. Thirty standard light bulbs turned on, collectively produce as much heat as a small space heater. You can keep the house much cooler by using CFL bulbs.
Install a programmable thermostat.
The use of a programmable thermostat to manage your energy use throughout the day can save you big money. Through proper use of pre-programmed settings, a programmable thermostat can save you about $150 every year in energy costs. It's important to adjust your thermostat schedule to your summer living habits.
Insulate with reflective barrier coating.
Truly a space age product, reflective barrier coating (sometimes called radiant barrier coating) can be applied to any surface—walls, ceilings and floors—but it is most effective when applied to the underside of roofs.
Roof surfaces are generally much hotter than sidewalls. Up to 80% of the source of summer heat increase is from above. When applied to building materials under the roof, radiant barrier coating can block up to 75% of radiant heat entering a home or building.
