Project Summary
89 Oxbow is an Energy Star rated 16-unit affordable housing development in Wayland, MA. The developer asked ZED to analyze the building design and performance, recommend cost-effective energy efficiency improvements, lead a green charrette, and provide financial arguments to support a green affordable housing grant application. Within this scope, ZED performed a cost-benefit analysis that factored energy performance benefits and cost data from a local contractor. With this analysis, ZED illustrated the total cost of ownership of improvements for each unit. With ZED's aid, the developer was awarded a $250k grant from the Department of Housing and Community Development (DHCD).

Project Summary
Five Lanterns is a luxury housing neighborhood at The Pinehills in Plymouth, MA. The developer and builder, The Green Company, asked ZED to provide energy efficiency recommendations and design the mechanical systems for the homes. The mechanical design/layout needed to be adaptable to different customer-selected building options. Cooperative efforts led to one of the best Energy Star ratings yet achieved by the builder. ZED also led a seminar for the Green Company's sales team that served as a primer to green building, energy efficiency, and where the Five Lanterns homes fell in the spectrum. Selected by Boston magazine as the Design Home 2008, the homes also received 5 national design awards including Best in North Atlantic Region award from the 2008 Best in American Living Awards.

Project Summary
The 100k House is an affordable housing project in Philadelphia, PA. The developer's concept was to build urban-infill, two-bedroom homes targeting LEED certification with only a $100,000 construction budget. With cost effectiveness being paramount for the project, ZED developed energy efficiency recommendations that reduced the home's energy use by 44%. An optional package with a slightly higher construction cost produced higher performance and included a solar thermal system.

Project Summary
Nauset Kennel is a 200-pen animal boarding house in Eastham, MA. It asked ZED to make energy efficiency and materials recommendations for their addition. ZED interviewed the proprietors to understand the kennel's unique operating requirements, including high hot water use and ventilation volumes. ZED recommended building improvements and heating and cooling systems that would save the Kennel money on operational expenses.

Project Summary
Conventional passive design principles include limiting west-facing glazing to mitigate unwanted afternoon heat gain. However, ignoring the spectacular west-facing view of Cape Cod Bay was not an option for this home in Truro, MA. ZED used performance feedback from its energy model to select design features that would compensate for the extra heat gain and meet the client's zero energy goals. The net result is that the Energy Star rated home uses two-thirds less energy than a code-built home; the remaining electricity use is offset by the solar panels atop the south roof.Learn More
