PREttyFAB is an award-winning prototype for energy-efficient, pre-fabricated housing designed for vacant infill sites in urban neighborhoods. In early 2008 our design for this specific house at 1 Minerva Street in Jersey City won the praise of the city’s zoning and planning boards who likewise saw its potential as the first of many of its kind, providing a viable bridge across the perceived schism between green design and economic viability. This 1600sf residence uses geometry to optimize solar collection, drainage, and passive heating and cooling while adhering to a low budget. Pre-cast concrete insulated panels (PIPs) fabricated by Northeast Pre-cast of New Jersey are utilized as high-energy performance structural walls between which the small structure is framed. The energy performance of this house is 30% better than a typical single-family home, making this design viable both in the short and long terms. PREttyFAB received an AIA New Jersey Merit Award for Built Projects in 2009 and a Jersey City Green Awards ‘Project of the Year’ 2010 from the Jersey City Redevelopment Agency.
