Net Zero Delta T90 House Maintains Comfortable Interior Temperatures During Subzero Vermont Winters


Recognizing a housing crisis in New England, where many renters and homeowners pay over a third of their income on housing, much of which includes homes that were built before 1950 and are extremely inefficient, the ∆T90 team at Norwich University in Vermont designed a high performance, affordable solution that has been accepted in the Solar Decathlon 2013 that takes place in October 2013 in Irvine, California.

Addressing concerns that include inefficient heating systems, insufficient insulation, and leaky construction of door and window assemblies that contribute to fuel costs that are sometimes equivalent to mortgage payments, the ∆T90 team took “an unapologetic design position” to deliver a modular home that is tailored to the northeastern region of the United States.

Philadelphia’s First Passive House Multi-Family Complex Ready for Occupancy


After years in limbo, Philadelphia’s first multi-family Passive House housing project is finished and on the market. Located at 219-235 W. George St., the homes were developed by the Onion Flats group in association with Domani Developers. The housing complex is known as the Onion Flats Stable. Of the projected 70 units, the team later downsized the project to only 27 units due to financial difficulties.

The units have a net living area of 2500 square feet, which includes 3 bedrooms and office space, and 3 bathrooms. About one third of the units in this development are set to be Affordable Housing units. This housing project was designed to obtain the LEED Platinum status, making it the first multi apartment complex in the US to receive this certification.
