Features of an Energy Efficient HomeEffective Insulation This means properly installed and high-quality insulation which reduces heat transfer to improve comfort; and protects homes from moisture damage which improves durability. EPS SIPs are a best practice for effective and efficient insulation. High Performance Windows Improved technology reduces heat transfer, multiple panes insulate better, Low-E glass reflects light and UV rays reducing the solar radiation that can fade fabrics, non-toxic gas fills insulate better, warm edge spacers reduce heat flow and condensation. Tight Construction and DuctsTo create a comfortable home, an efficient duct system is a must. 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. In a typical house about 20 percent of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. That’s why the duct systems found in ENERGY STAR qualified homes are third-party tested for tightness and verified to be properly insulated. Efficient Equipment Equipment plays a critical role in the efficiency of a home. Efficient, properly sized HVAC systems use less energy, reduce indoor humidity and are quieter than other systems. If a system is installed that is too large for the home, it not only costs more, but also operates less efficiently, and can cause comfort and humidity problems. Lighting and AppliancesENERGY STAR® qualified homes include ENERGY STAR qualified products from at least one of these categories:
Third Party Verification Home energy raters will provide a pre-construction evaluation of the project and two onsite visual inspections of the home during construction. The preconstruction evaluation provides the rater with an estimated rating for the home before any construction has begun. The rater will then make suggestions regarding the plan layout, orientation of the home on the lot, or other suggestions to better the home’s chances of being ENERGY STAR Qualified. The first inspection is designated as a visual inspection where the rater inspects air sealing and insulation details at pre-drywall stage using the Thermal Bypass Checklist. The second onsite visit involves testing equipment used to measure the leakiness of the building envelope and ducts. |
