Greenbelt Homes Pilot Program: Summary of Building Envelope Retrofits, Planned HVAC Equipment Upgrades, and Energy Savings
In fall 2010, Greenbelt Homes, Inc. (GHI) a 1,566-home cooperative of circa 1930-1940 homes in Greenbelt, Maryland, undertook a multiyear pilot energy efficiency retrofit project. GHI established this pilot project as a basis for decision making for the rollout of a decade-long community-wide upgrade program that will incorporate energy-efficiency improvements to the building envelopes and mechanical equipment. The community upgrade is fully funded by the cooperative through its membership with no outside subsidies. This project thus presents a unique opportunity to evaluate and prioritize the wide range of benefits of high-performance retrofits based on member experience with and acceptance of the retrofit measures implemented during the pilot project. Addressing the complex interactions between benefits, tradeoffs, construction methods, project management implications, realistic upfront costs, financing, and other considerations provides a case study for energy retrofit projects to include high-performance technologies based on the long-term value to the homeowner.

"description": "GHI has established a pilot project that will serve as a basis for decision making for the rollout of a decade-long community upgrade program that will incorporate energy efficiency upgrades to the building envelope from the exterior and equipment with the modernization of other systems like plumbing, mechanical equipment, and cladding. The pilot project has three phases focused on identifying the added costs and energy savings benefits of energy efficiency features that are to be installed during a planned community wide replacement program commencing in 2015. Phase 1 consists of a baseline evaluation of the current operation, use, environmental conditions, and energy costs for a representative set of 28 townhomes sited in seven buildings. "
