Many homebuyers are deeply interested in buying green homes. A good place to start is indeed, energy efficiency. That’s because the energy used in homes often comes from the burning of fossil fuels at power plants, which contributes to smog, acid rain, and risks of global warming. So, the less energy used, the less air pollution generated.

The Energy Star program of the U.S. Environmental Protection Agency is a good benchmark for what an energy efficient product in the home is, or what an Energy Star home is. This program is for both homes and businesses. This program can save home owners and businesses a big part of the energy bill.

Here are the features of energy star qualified homes:

1. Effective Insulation

Properly installed and inspected insulation in floors, walls, and attics ensures even temperatures throughout the house, reduced energy use, and increased comfort.

2. High-Performance Windows

Energy-efficient windows employ advanced technologies, such as protective coatings and improved frames, to help keep heat in during winter and out during summer. These windows also block damaging ultraviolet sunlight that can discolor carpets and furnishings.

3. Tight Construction and Ducts

Sealing holes and cracks in the home’s “envelope” and in heating and cooling duct systems helps reduce drafts, moisture, dust, pollen, and noise. A tightly sealed home improves comfort and indoor air quality while reducing utility and maintenance.

4. Efficient Heating and Cooling Equipment

In addition to using less energy to operate, energy-efficient heating and cooling systems can be quieter, reduce indoor humidity, and improve the overall comfort of the home. When properly installed into a tightly sealed home, this equipment won’t have to work so hard to heat and cool the home.

5. Efficient Products

Energy star qualified homes may also be equipped with energy star qualified products — lighting fixtures, compact fluorescent bulbs, ventilation fans, and appliances, such as refrigerators, dishwashers, and washing machines.

6. Third-Party Verification

With the help of independent Home Energy Raters, energy star builder partners choose the most appropriate energy-saving features for their homes. Additionally, raters conduct onsite testing and inspections to verify the energy efficiency measures, as well as insulation, air tightness, and duct sealing details.
