The top five reasons people are overpaying utility bills

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 insulation in exterior walls and attic
The US Department of Energy advises that additional insulation will improve a home’s energy efficiency when:
• The home is older and the homeowner hasn't added
   insulation. Only 20% of homes built before 1980 have
   sufficient insulated.
• The home's residents are uncomfortably hot in the
  summer or cold in the winter.
• Building or remodeling a new home, adding or installing
  new siding or roofing.
• Energy bills are high.
• Noise from the outside is bothersome—insulation
  provides soundproofing.
Insulation creates a thermal, or heat, barrier between your home and attic, and between your home and the outside. When your home is not thermally efficient more energy is required to maintain a comfortable living/working environment, reducing the energy efficiency of your home up to 30%. Adding insulation to exterior walls and attics will increase the energy efficiency of your home. Combined with proper whole house sealing and ventilation, additional insulation becomes even more effective.
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.
Properly insulating your home also reduces greenhouse gas emissions.
According to the Harvard School of Public Health, “Properly insulating homes worldwide would reduce the amount of carbon dioxide in the atmosphere by 293.5 Billion pounds over 10 years.”

The North American Insulation Manufacturers Association (NAIMA) states, “Reducing Energy Consumption reduces carbon dioxide and other greenhouse gas emissions. NAIMA estimates that insulated buildings in the United States reduce carbon dioxide emissions by 780 tons annually.”

High Quality Loose Fill Fiber Glass Attic Insulation PDF Print E-mail
At Green Building Energy Services, we furnish and install high quality loose-fill fiber glass attic insulation free from formaldehydes. Loose fill insulation is ideal for attics with hard to reach areas such as corners, edges and spaces around framing. Fiber glass attic insulation is superior to cellulose insulation and will not settle or decay over time.

We evaluate each unique home to determine the ideal type of insulation for the environment and will sometimes recommend a combination of insulation types for optimal home performance. Attics have unique configurations and we examine the location of equipment, ducting and framing to ensure that the solution we recommend will increase energy efficiency as well as improve the overall comfort in the home.

Improper sealing and insulation installation can actually cause more harm to homeowners.

During normal operation, gas appliances such as clothes dryers, water heaters, and furnaces release combustion gases (including carbon monoxide) through their ventilation systems. Leaky duct work in a heating and cooling system can cause "backdrafting," where these gases are drawn back into the living space, rather than expelled outside. Sealing leaks can minimize risk.
