Said to be the first certified Passive House in New York City,¬†Tighthouse represents an impressive energy-efficient renovation of an existing row house that’s over a hundred years old.

Architectural design firm Fabrica718 added a new rear facade, an additional story, a roof terrace, and an art studio to the house. Sustainable technology installed includes two solar thermal panels for hot water needs, and solar PV panels, which reduce grid-based electricity requirements. As the home is almost air-tight, a highly-efficient heat recovery ventilation system (HRV) is always running to provide plenty of fresh air.
