They completed construction around New Year's Day 2012, a great time of year to test how the energy-efficient elements stood up to the cold Maine winters. The envelope is very tight. "Insulation is key, especially in the attic," says Matero. "Houses lose most of their heat through the roof during the cold months. The walls, roof and basement were thoroughly insulated to LEED certification standards." This also means bringing in fresh air mechanically through a Rinnai air handler.
Matero used low-maintenance and durable materials such as a metal roof and fiber cement siding. The facade is broken up by board and batten accents.
"The galvalume roof changes from grays to blues. It's very organic. It looks like metal but reflects the color of the sky," says Matero.
