The HERS standard is set by the Residential Energy Services Network (RESNET), which, according to its website is:
– An industry not-for-profit membership corporation.
– A national standards making body for building energy efficiency rating systems.
The site asks: Who recognizes RESNET standards?
▪ Mortgage industry for capitalizing energy efficiency in mortgages
▪ Financial industry for certification of "white tags"
▪ Federal government for verification of building energy performance for:
▪ Federal tax credit qualification
▪ EPA ENERGY STAR labeled homes
▪ U.S. Department of Energy Building America program
▪ States for minimum code compliance in 16 states
OK, OK … you can see why it’s difficult to bring attention to the insulation topic. It can get a bit obtuse, particularly since energy-efficiency rating is still a fairly new industry full of obscure acronyms like HERS and RESNET.
Unfortunately, one needs to understand them to understand Robert Matto’s job at Sheep Dog Hollow as well as why I call him a walking, talking advertisement for home insulation. He’s not only done up his own home, but his job is helping other people do it right.
So here’s his personal experience, which has made him a believer.:
His house was built in 1961 and is just over 2,000 square feet. The only insulation it had was some R-13 rated fiberglass batt insulation in the attic and some R-19 in an addition to the house
The first year he and his wife lived in the house, they burned 1,588 gallons of oil to heat the house. After five years of upgrades, which included an insulation overhaul, new windows, doors, a new roof, a new boiler, and “a whole lot of air-sealing,” his oil usage dropped down to between 425 to 475 gallons a year.
“Insulating my house was probably the biggest factor in saving money, but I did other stuff, too,” he says. “It took me about $18,200 in upgrades to do this, but my payback was in six years. I am still saving at least $2,000 to $3,000 a year in oil savings.”
