New Construction, Energy efficient home, Berlin, MA.

This home was blower door tested and had a result of .175 air changes per hour. We did not apply to the
Energy StarTM program, but this result would have qualified it as a Tier II Energy StarTM home.
That means that every 5.75 hours, the air in the home is exchanged. In a typical Code built home, that number would
be closer to every 2 hours. This home will therefore consume 1/3 less fuel for heat and airconditioning than the average home.

The tightness of our home is due to superior insulation and air sealing. The entire home is insulated on the exterior
with a 1 1/2" layer of foam insulation that is sealed with foam spray at all interruptions. The interior is then also
highly insulated with blown in cellulose in walls and spray foam into all roof cavities.

Because of this superior insulation and tightness, fresh air is brought into the house using an ERV--Energy Recovery
Ventilation system. Fresh air is pulled into the bedrooms and main floor, and stale air is exhausted continually
through the baths. The heat from the exhausted air is used to preheat the incoming air through the ERV.
This inconspicuous system is equivalent to having your bedroom window open for fresh air and your bath window open
to vent, but allows the home to remain comfortable without that heat loss.

We are one of very few builders who are currently incorporating this level of energy-efficiency in their homes.
The construction costs are higher, but not nearly as high as the costs to retrofit a home to be efficient in the future,
and the payback begins immediately with lower fuel costs. It is our commitment to continue this level in all future projects.

In addition to high quality efficiency, we have incorporated quality and attention to detail throughout (see details below).

More details on the energy-efficient features of this home are:

  • 1) Superior insulation: Includes wrapping the entire house from under the slab to roof peak with 1.5" of extruded styrene foam insulation. All exterior bearing plates (fascia & soffit substructure, porch floor rim joists, porch roof rafter ledger, and ceiling rim, etc.) are connected over the foam, greatly reducing thermal bridging through the framing members. Interior walls & roof are further insulated with 5.5" blown in cellulose insulation (walls) and 9.5" blown in cellulose insulation (roofs).

  • 2) High performance windows: Harvey industries Tribute 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 consist of air source heat pumps, using 70% less energy/fuel costs than a traditional system for this sized home.

  • 5) Fresh air ventilation system: Indoor air quality is controlled by a energy recovery ventilator (ERV) with continuously supplied preheated outside air to the living space. Click here for more information on fresh air ventilation systems.
