这个3420万美元的项目是马萨诸塞州的最早大规模多户住房认证的开发项目之一，也是40年来剑桥最大的新型多户家庭经济适用房项目。18luck官网

Designed as a new type of housing development, the 124,000-sq-ft, 98-unit project addresses both climate change and the need for affordable residences.

六层楼的钢制和木框架结构采用开放式平面图，大型三层玻璃窗户，社区室，屋顶露台和景观美化的室外区域。团队说，车顶线就像飞行中的鸟的翅膀一样，启发了它重命名开发“雀科”。

The project—which attracted much interest from developers and architects and has inspired others to pursue Passive House certification—illustrates a growing national trend.

“The [project] stands out for pioneering Passive House in an affordable housing development,” one Best Projects judge said. “The design and construction were driven by climate, health and equity—three of the most pressing issues of our time—and serves as an inspiration ... for what can be accomplished within our industry to address these issues.”

该项目团队指出，开发中纳入了“高水平的建立质量和环境利益”。

“A primary function of Passive House is providing continuous air and thermal boundaries and minimizing thermal bridging,” the team said. To achieve this requirement, the team employed “an integrated and collaborative process” to evaluate structural choices that contribute to thermal bridge-free construction to reduce heat loss.

The team addressed sustainability through various elements. The lobby features an at-grade accessible entry that sits nearly 18 in. above the projected 2070 floodplain to reduce flood risk.

除了收集雨水径流的8,000加仑坦克外，团队成员还安装了一个文化屋顶系统，该系统在转移之前收集雨水，将液体固定在该物业的外围，直到暴风雨后可以将其吸收到地下水中。

The airtight building envelope comprises “a three-layer air barrier with additional air sealing at each opening” and fiberglass insulation and mineral wool in the wall cavities to limit thermal bridging, the team said.
