在波士顿，城市官员开始接受开发商的建议，在城市的特派团山区11个空置城市拥有的净零能源房屋。根据一篇文章Boston.com, the houses will be expected to produce more energy than they consume, not just be net-zero consumers.

班戈的Ecohomes

班戈项目是房子兴奋剂的工作nd Kelly Realty Management, which owns and manages both commercial and residential properties in the city of 33,000.

Kelly表示，第一所房子的细节仍在锻炼身体，但他目前倾向于一个结构2×4墙，具有非结构的i-托梁，产生腔体进行绝缘。“似乎真正的成本是可行的，并且可以容易地转移到该地区的绝缘和框架船员，”他说。

There are six potential house lots on the site. Preliminary plans call for houses in the 1,000-to-1,500-sq. ft. range, selling for between $200,000 and $250,000. Kelly expects most to be two-story designs and says it’s unlikely they’ll all look the same.

In addition to building high-performance houses, Kelly says a second important focus will be “permaculture site planning,” which he described as using landscaping and site features creatively.

“当我们设计被动太阳能避难所时，我们已经仔细地思考了它如何与周围环境进行互动，许多级别，”凯莉在后续电子邮件中写道。“生态设计涉及扩大超出壳的考虑因素 - 在整个网站上的景观环境。”

Boston’s E+ Community

Boston is collecting proposals for a mixed-use project of commercial, retail and residential space on 1.3 acres of land in Mission Hill. The project is part of an initiative launched by the city’s mayor in 2011 to encourage “deep green, energy positive, healthy and sustainable communities.”
