There are plenty of attractive features at the latest ranch-style home to go up at Cony Village, an affordable, green community in Augusta, Maine. The project’s concept was developed by two non-profit organizations, the Kennebec Valley Community Action Program(KVCAP) and Bread of Life Ministries. The house was designed and primarily built by students from the Capital Area Technical Center(CATC), a career and technical education school in Augusta. And finally, its main energy source is propane, which fuels a high-efficiency condensing boiler that provides both radiant heat and hot water, using an average of just 31 gallons of propane per month.

James Duchart, a student at the Capital Area Technical Center (CATC) in Augusta, Maine, nails shingles onto the roof of the latest energy-efficient house being built by CATC instructors and students at Cony Village.

According to Bruce Baker, CATC’s director and building construction instructor, propane condensing boilers have been gaining popularity in Maine in recent years, especially as the price of oil fluctuates. And of course, in addition to lowering heating bills, a switch from oil to propane results in a significant reduction of carbon emissions associated with the system.The homes, while not built to attain stringent LEED certification, must meet green standards required by the Maine State Housing Authority. The students’ volunteer labor helps keep the cost of the homes in the $140,000 range. CATC students have built four of the eight homes that have been put up at Cony Village in the last four years. The development, which also features shared green spaces and walking trails, can accommodate 41 homes.

“KVCAP, our funding source, looks at putting in the most economical system,” says Baker. “Dollar for dollar it costs less to put in a propane system.”
