 A 22,000 square foot ground up high rise commercial office building in New York city. This boutique building contains 8 full floor offices above a 3-level parking garage.

621 West 55th Street is being designed to meet US Passive House Institute standards for energy efficiency. Passive House standard emphasizes air-tight, continuously insulated building envelope without thermal bridges, high performance windows and balanced heat and moisture recovery ventilation. Passive House buildings are expected to consume 75-90% less energy than traditional buildings.


The biggest challenge for MEP systems was to minimize the impact of the high rise MEP system requirements on an relatively small floor plate (2,400 SF). A fire protection tank, standpipe, generator, ventilation systems all eat up valuable floor area and the project becomes less financially viable.  Morozov team worked closely with the architect to optimize MEP systems to achieve the largest possible usable area.


The building is cooled and heated with a variable-refrigerant system. Packaged rooftop energy recovery ventilator filtered and conditioned fresh air directly into each office in a continuous ventilation cycle.


MEP systems include a 150-kW emergency generator with a diesel tank, an underground suction tank for fire protection, and reversible air-flow parking garage exhaust system with post-fire smoke purge functionality.


SCOPE OF SERVICES full MEP design and construction administration services.
