Designs That Work case study: Cold Climate: National Grid Deep Energy Retrofit Pilot Program—Gloucester Coastal Cottage Retrofit
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 which is projected to achieve a 43% source energy savings for the occupants. The National Grid Deep Energy Retrofit (DER) Pilot Program provided technical and financial assistance for the energy saving improvements of the renovation.
Designs That Work case study: 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. The building had been in a state of significant deterioration, yet preserving the footprint and first floor framing was essential to preserving the ability of Habitat to provide a home on the otherwise non-conforming lot. Due to programmatic requirements, the roof was removed and a new second floor and roof framed on top of the existing balloon-framed structure. Significant parts of the rubble-stone-and-brick foundation wall also required replacement. The interior of the remaining first floor was completely gutted.
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.
New Orleans, LA
The Green Dream 2 is a single-family home built on the site of a hurricane-damaged house that stood for 3 years before being demolished by the city of New Orleans. Staff and students from Portland Community College met the homeowner and his family on a trip to New Orleans and wanted to help them by building a new home; one that would be durable, healthy, comfortable, energy-efficient and affordable. Portland Community College connected the homeowner with Catholic Charities Operation Helping Hands who, in turn, asked BSC and the LSU AgCenter to be a part of the team.
This is a first foray into Building America-level performance for the builder, Jim Pepitone and his company, Ark Ventures, LLC. Building Science Corporation (BSC) supported Ark Ventures on the design and construction of the Greenbrier prototype, the model home for a 14 unit subdivision in which the builder intends to demonstrate his concept of “attainable sustainable.”
Habitat for Humanity of Greater Lowell (HfHGL) has partnered with Building Science Corporation (BSC) on previous new construction projects. This working relationship continued with HfHGL’s renovation of a mid-19th century farmhouse into affordable housing meeting Building America performance standards. BSC guided the project through the compound challenges of implementing high performance construction in the context of Habitat’s construction process and in the context of a 150 year-old structure in an historic district.
ZETA Communities is a startup company that has a mission of building energy efficient and/or net zero modular houses at costs competitive with local construction. They recently completed their first prototype, the live-work townhome: an infill project located in a mixed industrial/artist/residential urban neighborhood, within walking distance of a mass transit station. The plan provides a ground floor work studio, 2 bedrooms, light-filled great rooms, decks, and sustainable landscaping, in addition to a one-car parking garage.
Designs That Work case study: Cold Climate: National Grid Deep Energy Retrofit Pilot Program—18th Century Cape Comprehensive Retrofit
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.
Habitat for Humanity of Greater Lowell bought the land on which to build the Westford House from the town of Westford for $1. Habitat then partnered with Building Science Corporation, the community, local and national manufacturers, distributors and donors in an effort to create a comfortable, healthy, durable and energy efficient single family home.
New Orleans, LA
Phase II is a continuation of a charitable residential community in New Orleans called Project Home Again. Project Home Again is a not-for-profit organization that is overseeing the construction of 12 affordable and energy efficient single detached residences in Gentilly, New Orleans. The project is managed by Green Coast Enterprises, a local real estate services firm. A local architect and builder (Sustainable Architecture, LLC. and TKTMJ, Inc., respectively) were hired in large part because of their extensive expertise and willingness to embrace Building America building practices. These single detached homes demonstrate the energy efficiency and durability upgrades that BSC advocates.
