To understand why the home received recognition from the AIA, you simply need to add: style + affordability + performance = winning. The 1,100 square foot house came in at below $150,000 which is a pretty good value, but that’s just the beginning of its economy. Using the aggressive Passive House standard for a super efficient shell, the home needs no dedicated heating system. Most of the time the occupants and appliances will be enough to maintain temperature. The southern windows allow for solar heating and abundant light and a finished concrete floor maintains that heat for a New York winter day.
