Energy Star Home
Royalston Home Wins $8,000 Energy Incentive Award
June 6, 2012
A typical new-construction home of the same size would have energy bills of about $340 per month, but the Doub-Musco residence is expected to average monthly electric bill of about $200. The house is 100% electric, so the monthly electric bill will cover heat, hot water, all lights, all appliances including a dishwasher and a clothes dryer.
The Massachusetts New Homes with Energy Star program offers three tiers of incentives to reward those homebuilders who build super-energy efficient new homes.
“It’s exciting to see builders, homeowners and architects striving for such deep energy savings — the homeowners will enjoy the results for years to come — a more comfortable home that costs less to operate,” said Megan McDonough from the Center for Ecological Technology. CET performed the required home energy rating (HERS) analysis and third-party inspections that led to the homeowners qualifying for the $8,000 Tier III incentive. The house also received an Energy Star rating of 5 Stars Plus, the highest possible rating.
CET has been encouraging builders to make energy-efficient choices through the Energy Star homes program since it began in 2003.
The house of Josh Doub and Lydia Musco is a tall posted cape designed by Royalston Oak Timber Frames of Royalston. It has an oak and pine timber frame that is enclosed by super energy efficient Structural Insulated Panels (SIPs). All the wood for the timbers and the first and second floor decking came from the building site and managed woodlots in Royalston. Tom Musco of Royalston Oak cut the frame and supervised the frame raising in June 2011.
“We have been designing and building energy efficient homes since 1977,” said Tom Musco. “ People are finally getting really serious about energy efficiency and we have the tools now to quantify just how efficient a home of our design can be.”
“What I really like about this house is that it does not use any exotic systems or triple glazed windows,” Musco said. “It has electric baseboard heaters and an conventional electric hot water heater.”
When asked if building an energy efficient house was harder than conventional building Josh Doub, who was his own general contractor and did all the work to finish the house except the roofing, electrical and plumbing said, “ Timber frames are anything but conventional. The structural insulated panels are the best material to create a high-R value, low infiltration envelope for a house. But they present other challenges, especially for plumbers,” said Doub. “Start with a good house design, use the highest R-value panels you can afford, and Energy Star rated windows and you will be on your way to having an energy efficient house.”
