Passive Houses, Super Energy Efficient Pre-Fab Homes

In Seaersmont, Maine a company called Ecocor uses European design principles and tools to build what are referred to as passive houses. These super energy efficient pre-fab homes are assembled on location from wall, floor and roof panels manufactured at the factory. WBGO’s Jon Kalish visited Ecocor and then watched as their team assembled a house near Woodstock, New York.
