David Weekley Homes is actively reducing the energy consumption of their homes through the implementation of their "Green Homes" program, which is intended to promote certain features designed to make homes more economically sustainable over the long term and reduce energy usage and the resulting environmental impact.
Phase II is a continuation of a charitable residential community in New Orleans called Project Home Again. These single family detached homes demonstrate the energy efficiency and durability upgrades that BSC advocates.
In 2000, the Aspen Area Community Plan called for affordable housing projects based on the goal of housing at least 60% of the city employees within the city limits and the Burlingame Ranch project is one major step towards achieving this goal.
Hamilton Way is a ten-lot community designed and constructed to optimize design and increase efficiency through various strategies and weigh them against the energy consumption reduction, cost, and potential value in marketability.
David Weekley Homes have many developments in the Houston area, however the Eagle Springs and Waterhaven developments are intended to be a test of the technologies and construction techniques required for high performance houses.
The real value lies in implementing building science principals within a systems engineering approach to high-performance housing.
Building Science Corporation collaborated with ICI Homes in Daytona Beach, Florida on a prototype house that demonstrates the energy efficiency and durability upgrades that ICI promotes through its in-house efficiency program.
BSC collaborated with Greencraft Builders in Lewisville, TX on a 2009 prototype house called the TimberCreek Net Zero Energy House. This house demonstrates the energy efficiency and durability upgrades that Greencraft has been promoting for years.
Sandstone is a 49-home subdivision located in Ellendale, DE. The project is Colter Construction’s first entry into community-scale development.
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.
This Cape Cod style house was built in 1953. While the owners had made interior improvements and necessary repairs in the 25 years since they purchased the house, they now wanted to do some exterior upgrades and at the same time tighten up the house in keeping with their long-standing goal of becoming energy efficient and reducing their impact on the environment.
Cold Climate: National Grid Deep Energy Retrofit Pilot Program—Comprehensive Retrofit of 1859 Victorian
The owners of this circa 1800 Victorian have been postponing renovation and performance upgrade for years in anticipation of a major change in the household structure. With the likelihood of an aging parent’s arrival, they decided to rebuild a portion of the home and add new space to provide a ground floor bedroom with an unfinished office space above.
Cold Climate: National Grid Deep Energy Retrofit Pilot Program—Second Floor Reframing Comprehensive Retrofit of 19th Century Small Colonial
Habitat for Humanity North Central Massachusetts received this circa 1900 property as a donation from the Town of Lancaster and the project plan needed to be formed around donated materials and volunteer labor. The result is a project that serves as an impressive example of what is attainable under such circumstances.
Cold Climate: National Grid Deep Energy Retrofit Pilot Program—Cape Basement Renovation Turned Comprehensive DER
This test home provides an example of a thoroughly comprehensive retrofit that did not involve major additions or changes to the building footprint but, nonetheless expanded living space by including the basement within the thermal enclosure.
Cold Climate: National Grid Deep Energy Retrofit Pilot Program—1960s Garrison Colonial Comprehensive Retrofit
The retrofit project for this home included a comprehensive enclosure retrofit and new heating, cooling and ventilation systems.
Cold Climate: National Grid Deep Energy Retrofit Pilot Program—Retrofit and Addition to 1905 Bungalow
When the owners of this bungalow-style home in Quincy, Massachusetts originally decided on a major expansion, significant energy improvements were not part of their plan.

Cold Climate: National Grid Deep Energy Retrofit Pilot Program—Three-Story Victorian Partial Retrofit
This home provides an example of a staged approach to a comprehensive retrofit. New retrofit measures are carefully thought out and integrated with the measures implemented previously. This staged approach may be a more realistically accessible path to broad adoption of DER.
In 1920, when this house was built on the bank of a coastal cove, it served as a summer cottage complete with a boat dock. Over the years, the house has been remodeled, added to, and converted to a year-round residence. Now, as part of the latest renovation, it has undergone a deep energy retrofit.
