100 Flatbush is set to become the first all-electric residential tower in New York City, with electrical power replacing components normally run by natural gas.
New York City’s first all-electric residential tower
The 1 million-square-foot mixed-use 100 Flatbush development in Brooklyn consists of two residential towers sitting on a podium with commercial, office, cultural and retail spaces along with two public schools that will also serve community organizations. The residential towers are 840 feet and 510 feet tall, adding 870 units to the neighborhood, with 200 set aside as affordable units.
The complex also houses the 350-seat Khalil Gibran International Academy, which comprises an elementary and a high school, and features classrooms, reading rooms, labs, libraries, playground and terraces, dining areas, student support spaces and administrative spaces.
We are providing sustainability services to Alloy Development for the complex, which is on track to be completed in 2023.
Highlights
- The residential towers are maximizing energy savings by including sustainable interior finishes, targeting a widow to wall ratio of at least 45 percent, designing a water source heat pump with a perimeter heating system, keeping perimeter heating to a minimum and reducing glare by manipulating the façade design and integrating nature and natural systems into its landscape and overall design.
- The school façade comprises a continuous insulation layer and an airtight envelope that will efficiently maintain comfortable interior conditions. This will reduce heating and cooling demands for the mechanical systems as well as primary energy demands for the entire school.
- The school will further maximize energy savings by incorporating well-placed, well-sized and high-performance windows to fully light classroom spaces, using 60 percent widow to wall ratio as a rule of thumb and requiring ventilation to meet ASHRAE 62.1-2013 at minimum.
- The school demonstrates a 35-40 percent energy savings from an equivalent 2016 NYC-EEC code compliant building and is on track to achieve a 29 percent energy savings.
