When: Sunday, March 4, 2012, 12 Noon — 3 PM
Where: 61 Oakwood Avenue, Sudbury, MA
National Grid will be sponsoring an Open House showcasing the Deep Energy Retrofit (DER) of a single family residence at 61 Oakwood Avenue in Sudbury, MA. Synergy Construction LLC, the project’s DER envelope subcontractor, and October Engineering LLC, the owner and mechanical systems installer, will be on hand to discuss the concepts and construction details. The home was built in 1961.
The owners, Deborah Wolozin and Robert Morrison, purchased the home in 2010 as a rental property in one of Sudbury’s family-friendly neighborhoods. A subsequent home energy audit and review of utility bills revealed its poor energy performance. The owners were uncomfortable passing these high utility costs onto future tenants. In the course of researching window replacements and air-sealing energy retrofits, they discovered the NGrid DER Pilot Program. The owners decided on an expanded financial planning horizon which incorporated the benefits of the pilot program to pursue a gut-rehab, deep energy retrofit in conjunction with a second floor expansion.
The super-insulated and air-tight enclosure, made possible through financial and technical support from National Grid and Building Science Corporation, will include interior spray foam insulation for air sealing and insulation in addition to an exterior insulation wall and roof build-out. A heat recovery ventilator will provide fresh air while recovering energy from exhausted air. A premium efficiency hot water heating system is being installed. A multi-split system heat pump will be installed for air conditioning and backup heating. A solar photovoltaic array is currently being designed. The project is aiming for completion by July 2012.
