International Green Building Challenge 1998 — Cambridge Cohousing

Cambridge Cohousing is an infill residential project consisting of 41 units of housing on a narrow 1.5-acre site between the street and a railroad track. The housing units range from large, 3-story townhouses to 1, 2, and 3-bedroom flats. The also includes communal facilities including a large kitchen, dining area, childcare and recreational facilities, a library, and shared gardens.

To minimize automobile use, the community was intentionally located within walking distance of public transportation, including buses and the subway. Shopping, services, and entertainment establishments are also within walking distance. Underground parking is also available.

Cambridge Cohousing is designed to require a minimum of energy for heating and cooling. These loads are met with a district heating/cooling system consisting of heat pumps and a boiler. A unique air distribution system within each units draws off water circulated from the central plant to provide heating, cooling, and ventilation. Materials for the project were also selected to minimize environmental impacts.
