Paul Lukez Architecture has big dreams for the PV+ House, a prototypical "zero energy" or "energy plus" home. Based on the design of a classic New England barn and a New York loft, the building combines different architectural styles with sustainable strategies that turn conventional buildings into modern green homes. The project was awarded second place in the “Small Lots / BIG IDEAS” competition.
Among the several sustainable features is a roof that uses an inverted scissor struss that provides optimal solar orientation and allows air to flow through the house. Natural ventilation is also aided by the presence of louvers on the north side. A series of insulated panels can be closed during the winter and at night and help maintain optimal temperatures. Colder air from the basement is brought into the space via air ducts.
Indirect daylighting in the winter and minimized solar gain during the summer are acquired through the introduction of overhangs and openings on the southern facade, trees and different reflective materials, along with hyper insulated walls. Rainwater is collected in cisterns, while the PV panel array is 735 square feet with each panel producing 240 megawatts.
