In June of 2009, National Grid launched a pilot program intended to demonstrate Deep Energy Retrofits (DER) in existing Massachusetts homes. The pilot program provides financial incentives and technical support to projects that commit to achieving significant energy reduction and successfully complete a long application process. The open application process is intended to bring a variety of housing types and retrofit approaches into the pilot.
September 2010 saw the completion of the second project participating in National Grid’s Deep Energy Retrofit (DER) pilot program. This program provides financial incentives and technical support to residential retrofit projects that commit to achieving significant energy reduction. As the Technical Team in this pilot program, Building Science Corporation (BSC) supports the projects by evaluating and approving project plans, providing technical support, and performing site visits for verification of measures and testing. BSC also supports the program by participating in DER workshops.
The retrofit project included new fiber cement siding installed over exterior insulation, new high performance windows, a conditioned basement, improved insulation at the attic and roof, and improved air tightness.

The Cleveland Prototype Housing designs will demonstrate sustainable building practices by integrating a number of strategies into one very sensible design solution: using recycled, low-polluting materials and controlled ventilation equipment to preserve natural resources and support environmentally progressive industries. By efficiently using inner city land, this development will help revitalize downtown areas while reducing traffic, pollution and energy use from commuting.
A premise of the Building America program is that high performance homes must be sustainable both environmentally and economically. EcoVillage Cleveland takes this premise to a new level. From location to lumber to lighting—energy efficiency, resource efficiency, and durability rule at EcoVillage Cleveland, but withou affordability. EcoVillage Cleveland is about local and individual sustainability.
Typical homes have no way of providing outdoor air in a controlled manner aside from relying on the construction of leaky homes and the whims of the weather (wind and temperature differences). Leaky homes consume energy and tend to be uncomfortable from drafts. Tight homes without controlled ventilation can also have problems due to a build up of odors and other pollutants. The optimum approach for healthy, safe, comfortable, energy efficient homes is to construct a tight building envelope and provide controlled mechanical ventilation.

Although most people associate the term zero energy with solar panels, the starting point must always be the efficiency of the structure and its heating/ventilation/air conditioning (HVAC) system. The way to really fine-tune the energy performance of a building is to treat the structure andthe HVAC system as integrated systems, matching their features and individual contributions to the whole.
BSC collaborated with Greencraft Builders, LLC in Colleyville, TX on a 2009 prototype house called the Colleyville House. This house demonstrates the energy efficiency and durability upgrades that Greencraft currently promotes in all of their products. The Colleyville house is located in Colleyville, TX, about 25 miles North West of Dallas. The house was designed by William Peck and Associates, an award winning architect specializing in sustainable energy efficient architecture.
The design of the Concord Cape began in August of 2008. Architects and engineers at BSC developed the drawing set and specifications for the high performance custom home to be built in Concord, Massachusetts. The house is a Cape Cod style design with 5 bedrooms, 4 full bathrooms, 2 stories plus a finished basement. It is built into an existing neighborhood close to public transportation, restaurants, shops and other community resources. BSC worked closely with the homeowner to design a house that combined the desired design aesthetic, both interior and exterior, with high performance.
It shouldn’t be a surprise that energy would be a hit in Texas—but 8,000 people on the fi rst weekend to tour a home that uses less than half that of a standard new home, and makes the rest itself? There is no magic in the technology and engineering, but clearly builder Jim Sargent and his systems thinking team have created something special at the Building America Zero Energy Home of Lone Star Ranch in Frisco, Texas.Project Team: Anderson Sargent Builders, Barley Pfieffer Architects, Building Science Corporation, EEBA, US DOE Building America ProgramAddress: Dallas, TexasAt the first-of-its-...
