Passive House - Residential Building, Brooklyn NY
TOTAL GFA: 20,494SF
55 Summit residential building in Brooklyn is a designed Passive House by Builtd that inhabits on the West side 5 story multi-family block and 4 townhouses next to it, all read as a whole. In order to accomplish to Passive House standard created by an international body pushing for high-efficiency, thermally comfortable buildings, the site's relative orientation was taken into consideration as well as highly insulated walls that are used around the entire building envelope, with a weighted U-value more than twice that required by the building code; in conjunction with an air-tight layer wrapping the building, this should greatly reduce the amount of energy used to heat and cool the building.
Large triple-glazed windows with insulated frames allow for interior thermal comfort, while providing large vistas out for the residents, and reducing the amount of lighting required during daylight hours. The mechanical system placement on the building's bulkhead frees up the space on the roof for passive recreation by the residents, increasing activity levels and residents overall comfort. For the multifamily section the design of the lobby and stairs encourage active use of the stairs, with a wide entry corridor, partially glazed stairwell doors, and well designed and easily visible placement of signage that will remind residents of the importance of moving.
The rooftop and building's ground level setback will be used for passive recreation, with the addition of planter boxes to facilitate residents gardening and hyper-local food production; permanent planter boxes are proposed for both the roof and ground levels. A bike storage area is provided within the building setback, in addition to existing bike-racks on the sidewalk, allowing for ample bike parking on-site.
Overall, residents will have a variety of means to stay active built into the design of the building. With all of this built into the physical design of the building, it should prove as a model for sustainable building construction for years to come.
