100K House | First LEED Homes Awards "Project of the Year"

Philadelphia, Pennsylvania

100K Houses were conceived as a response to the unsustainable “bigger is better” approach to housing, offering a 1,000 square foot (9.3 square meter) efficient, sustainable house model built for less than $100 per square foot.

The design team focused on creating a tight, super-insulated building envelope—using SIPs or double-stud framing—rather than on elaborate mechanical systems. That, plus items such as photovoltaics, solar thermal hot water, and ductless mini-split heating and cooling helped the 100K homes achieve LEED Platinum certification

Seven homes have been built to-date, providing sustainable, affordable options for first-time Philadelphia homebuyers.
