The results of Boston’s E+ Green Building Demonstration Program will be on display through September 25 at the Boston Architectural College.  The E+ program’s goal is to promote the next generation of ultra-efficient green buildings.  The exhibition features proposals generated by 11 teams of architects, builders, and developers detailing the design and construction of high-performance, green urban homes, and demonstrating the feasibility of regenerative buildings.  The winning teams will construct residential buildings on three parcels of city-owned land in Roxbury and Jamaica Plain.  It’s possible that the results of this program will provide the impetus for changes to Article 37 (Green Buildings) of the Boston Zoning Code, and will be used as review standards for future projects.  In any event, it’s a chance to get a glimpse of the future and see which new ideas might be feasible for current use in building design.
