Engineering challenges

  • Maximizing ceiling heights, while also providing fully ducted systems throughout.
  • Providing individual systems (instead of common) for each apartment, while also complying with landmarks requirements.
  • Minimizing floorspace required by MEP systems, saving valuable square footage for the residences.

Engineering outcomes

  • Separate Variable Refrigerant Flow (VRF) systems were provided for each apartment, providing a multi-zone system that allows for individual control of each space.
  • Condensing unit, fan and other rooftop equipment locations were oriented to be out of the sightline from the street and adhere to NYC Landmarks specific requirements.
  • Careful consideration was provided during the MEP design process to ensure that sprinkler and plumbing distribution did not cross with heating/cooling ductwork, in order to maximize ceiling heights.
