This six-story, 24-unit project was the second affordable housing structure in the country built to “passive house” standards. It features six units designed for disabled residents. The project includes a rooftop terrace and rear parking lot, but most notable is the energy efficiency of the building. Knickerbocker will consume just 10% of the energy normally consumed by a building of its size. It features a wedged foam and stucco facade that shades windows from the sun in the summer, collect rays in the winter and provides insulation, as well as energy recovery ventilators, triple-pane, 700-pound windows and lining that covers the building putting it past the national passive standard.
