Energy Star Homes

Although Massachusetts’ code has a standard for duct leakage, code officials do not test duct performance like the program. When the Energy Star program changed in 2006 and the Thermal Bypass Checklist (TBC) was added to the technical specifications, many builders struggled to meet the TBC. Success in the program comes down to training and engaging all subcontractors to conform and adhere to the technical specifications.

• 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 overall comfort. The equipment is typically more durable and requires less maintenance than standard models.
•  Efficient lighting and appliances. Energy Star-qualified homes may also be equipped with Energy Star-qualified products—such as lighting fixtures, compact fluorescent bulbs, ventilation fans, refrigerators, dishwashers and washing machines—to provide additional energy savings.
• Third-party verification. Independent Home Energy Raters conduct on-site testing and inspections to verify the energy-efficiency measures. Certified raters can be found, for example, through RESNET, Residential Energy Services Network.

Benefits for Homeowners
Besides better protection against cold, heat, drafts, moisture, pollution and noise, an Energy Star-qualified home provides consistent temperatures, improved indoor air quality, and better durability. It also helps save money. 

Ceci Anderson, director of marketing for Veridian Homes in Madison, WI, says that “on average, our homeowners save $813 per year on utility bills compared to a new home built to code. Over a five-year period, they save $4,065. In addition, if a homeowner replaces light bulbs with CFLs, they could save an additional $200 annually.”
