NYC’s first Passive House public schools open in Downtown Brooklyn

New York City's first Passive House-certified public schools have opened in Downtown Brooklyn, setting the bar for sustainable education. Designed by Architecture Research Office (ARO), the ultra-low-energy-use building houses two schools: the Khalil Gibran International Academy, the nation’s first English-Arabic public high school, and the Elizabeth Jennings School for Bold Explorers (aka P.S. 456). Part of the mixed-use development Alloy Block, the facility consumes less than a third of the energy of a typical NYC public school.

Construction set to begin on five-building Alloy Block development in Downtown Brooklyn

By Devin Gannon

After securing $240 million in financing, Alloy Development announced construction will kick off this month on its huge mixed-use, multi-building project in Downtown Brooklyn. Formerly known as 80 Flatbush, Alloy Block includes five buildings with 850 apartments, 200,000 square feet of office space, 40,000 square feet of retail, and two public schools designed to meet Passive House standards. Since first announcing the project roughly four years ago, developers have cut the height of the residential towers, swapped out planned office space for additional residences, and pushed back the expected completion date.
