Uncontrolled air entering and leaving the home

The average 2,500 sq ft building has more than a mile and a half of cracks and crevices that are open to wind and moisture.

Leakage occurs when outside air enters your building uncontrollably through cracks and openings. Air infiltration can also contribute to problems with moisture control where moisture moves through air currents. Additional problems are caused by heat transfer and diffusion, where moisture spreads out through materials

Air sealing is one of the most effective energy improvements for your home. Green Building Energy Services offers whole home air sealing to create an effective air barrier that prevents unwanted air from entering and leaving the home. Weather-stripping, environmentally safe foam, caulking, and proper ventilation, can reduce leakage by up to 35%, improving your home's energy efficiency and reducing the chance of moisture problems.

Insufficient Attic Ventilation
Whole house ventilation is unlikely to be effective in hot, humid climates like those in central Texas. Without attic insulation, attic temperatures may rise to over 150 degrees fareinheight. In the summer, if your home is not properly sealed, the hot air in the attic will find its way into your home.

The Department of Energy studies show that ventilated attics are about 30°F (16°C) cooler than unventilated attics.

Attic ventilation systems provide an inexpensive and energy efficient method of cooling your home. In these climates, attic ventilation can help to reduce your use of air conditioning. Ventilating your attic greatly reduces the amount of accumulated heat, which eventually works its way into the main part of your house. Properly sized and placed louvers, roof vents, ridge vents, and attic fans help prevent moisture buildup and overheating in your attic.

Leaky Ducts
Duct leakage is responsible for nearly 20% of energy efficiency loss in a home or office. Gas appliances such as water heaters, clothes dryers, and furnaces release combustion gases through their ventilation systems. Leaky duct work may cause "backdrafting," where gases are drawn back into living spaces, rather than expelled outside. Sealing leaks can minimize risk of exposure.

Sealing and insulating ducts increases efficiency, lowers energy bills, and pays for itself in energy savings. Plus, If you're planning to install new heating and cooling equipment, a well-sealed duct system may allow you to downsize to a smaller, less costly system.

Sealing ducts can help improve indoor air quality by reducing the risk of pollutants entering ducts and circulating through your home.
