The Boston Society of Architects' Sustainable Design Awards for 2009 were on display at Residential Design and Construction (RDC), their annual residential convention and tradeshow. As a recipient of an award this year, our award, -- Jamaica Plain MA Sustainable Design Award-Citation for social sustainability -- was included in the BSA Design Gallery.
"It is my hope that these awards will encourage Boston businesses and residents to engage in environmentally sustainable practices, learn more about such practices and initiate their own sustainability efforts and programs." - Mayor Thomas M. MeninoEnergy Saving Decisions
JP Cohousing was built with a clustered design to reduce heat-loss and heat-gain. We included as much passive solar heating as possible by maximizing the amount of south-facing walls and windows, including a two-story solar atrium in the Common House.
We were built and certified as Energy Star Homes with the following features: High insulation in the walls, roof and foundation. Walls have an R-value of at least 22; roof R-38, slab R-15.
High-efficiency windows with low U-values and high solar glare reflection on east and west faces to reduce solar heat gain in summer, and low solar glare reflection on south face to increase solar heat gain in winter
Tight weatherization air leakage max. 2 square inch per 100 SF of shell. Mechanical ventilation brings in fresh air from the outside in a regulated flow, ensures a healthy air environment in the homes; heat recovery in the ventilation recaptures warmth of outgoing air.
Boiler/baseboard heating system with highly efficient gas furnace at least 87% EFUE and boiler reset controls.
Water saving shower heads and faucets to reduce hot water needs.
We do not have central air conditioning in the units due to a design that promotes natural ventilation and reduces direct sun in summer months.
Full spectrum, fluorescent lights are standard in all units and common areas.
Energy Star appliances are standard for units and common house.
We have a highly efficient gas washer and dryer in the common house laundry.
We do not have piped water for irrigation. We landscape with native plants using drip irrigation from our rainbarrels that catch rainwater. Natural pesticides and fertilizers only.
We have set aside 5000-10000 SF for an organic food garden on site. We hope to educate our children and members in organic urban gardening.
We are a CSA drop-off site in the summer and fall.
We continue to encourage public transportation use by subsidizing T passes and by having a community subway pass.
We encourage people to use bicycle transportation by maintaining secure, covered bicycle storage for residents in the building 1 basement. We are in the process of organizing our own carshare co-op since Zipcar abandoned us.
