Eastern Village Cohousing (EVC) is a green building that represents a new direction in mixed-income, urban, residential development. Located in downtown Silver Spring, Maryland, it consists of 56 residential condominium units. Cohousing communities such as EVC constitute small-scale neighborhoods providing balance between personal privacy and community living, wherein neighbors share in community activities, decision-making, work, and play. Residents have been involved from the beginning of the project, helping to plan and program EVC, and will participate to a high degree in the management of the community.
The EVC building is an adaptive reuse of an abandoned office building originally constructed in the 1950s. The structure's courtyard had been a parking lot but is now a green space that includes benches, sculpture, a patio, and a children's play area. EVC incorporates such features as ground-source heating and cooling, low-emitting finishes, some rapidly renewable materials, and a vegetative roof. Multifaceted commissioning was employed to ensure best practices and compliance with design requirements during the construction phase.
The U.S. Green Building Council's LEED(r) Rating System provided the primary framework for the design team to explore green building strategies best suited for the project. The U.S. Green Building Council awarded ECV LEED Silver certification in September 2005, making it the first LEED-certified cohousing structure.
Residents, many of whom contributed to the design process, actively participate in the management of the facility and grounds, including "green housekeeping" and other low-impact maintenance strategies where practical. The resident group has agreed contractually to install only Energy Star(r) appliances, both initially and through a replacement policy.
