We are currently building a 3030 square foot, custom designed energy-efficient 4 bedroom home on a private 5 acre lot on Still River Road in Harvard, MA. This home will be built to exceed the ENERGY STAR^TM home program requirements by using advanced air sealing, insulation and ventilation techniques combined with cold-climate building science to produce a durable, low maintenace, low cost, comfortable, healthy home.

The energy-efficient features our home will have are:

1) Superior insulation, including 2" of isocyanurate foam on the exterior walls and roof sheathing, and 3.5" of blown cellulose on inside of exterior walls, 9.5" of blown cellulose on inside of exterior roofs.

2) High performance windows: Harvey industries line of Double Low E, Krypton filled, triple-glazed windows with an R5 performance rating.

3) Tight construction: All areas of potential leakage in the building envelope are sealed with spray foam to reduce air leaks, moisture issues, dust, and noise.

4) Efficient Heating and Cooling Equipment: Because of the tight construction and insulation, the home’s heating and cooling system will use approximately 70% less energy/fuel costs than a traditional system for this sized home. The heating system will consist of a Munchkin propane fired condensing boiler, a First Company air handler on the upper floor (both heating and A/C). The lower floor will be heated and cooled using a Fujitsu air source heat pump with supplemental baseboard heat as a backup for extreme cold periods. In addition to all fossil fuel burning appliances being supplied with their own outside air supplies, the house will use an Imperial heat recovery ventilator which will continuously exhaust air from the bathrooms while supplying pre-heated fresh air back to the living spaces of the house.

5) High efficiency water heater: The home will have a Superstore solar hot water with an optional 2 panel evaculated tube collector system.

The home was custom designed by the Warren Design Build team to suit the location and western views, see plans below.

Sale information: Home is projected to be listed for sale in April. You may contact us and/or our real estate agent, Maryann Sargent of Coldwell Banker, Bolton, 978-779-2247, for further details. Please note that some of the above details may be altered during construction.
