If you're in the area, the next project by Postgreen, the development company behind the award-winning 100k House, will be open for tours on Thursday, December 17.  Dubbed The Passive Project, the tour will include two newly constructed row houses built to a rigorous and trendy German Passiv Haus standard.  When certified, these homes — located at 2318-2320 Amber Street — should be the first to do so in the Philadelphia. 


Talking about the M&M House shown in these images (Postgreen named one home after future owners Mario and Mel), Lloyd Alter of Treehugger recently commented: "[the M&M House] demonstrates that one really can mix simple, economical materials and good design with incredible energy efficiency."

Indeed, these homes were designed and built to be extremely energy efficient.  The envelope is air tight and an energy recovery ventilator refreshes the interior air.  The homes practically run without the need of extra mechanical systems, although there's a 2.04 kW solar array and solar thermal system that should lower utility bills to zero. 

The Passive Project also includes dual-flush toilets, low-flow fixtures, a rainwater cistern, high efficiency appliances, Ecotop counters, custom bamboo kitchen cabinetry, finished OSB floors and stair treads, birch plywood detailing, and raised garden boxes in the backyard.
