This 39-unit residential condominium building was designed by the Pritzker Prize-winning Iraqi-British architect Zaha Hadid, and developed by Related, directly on the High Line in West Chelsea. It has an intricate metal and glass façade, a 2,500 square foot sculpture deck, a gallery in its commercial space, automated underground parking and a robot-operated storage facility.
Vidaris’ energy modeling helped the design/development team select a number of outstanding energy efficiency features, including a window wall with large glazed expanses. The double-pane insulating glazing has U=0.28, inclusive of window frames. An efficient chiller and condensing boiler provide year-round comfort.

To ensure that the HVAC systems and the envelope work in concert, Vidaris evaluated design options being considered for the Grand Room and representative bedrooms using computational fluid dynamics (CFD). Long-term operation of the building in an efficient manner will be ensured via periodic measurement and verification. Vidaris developed the Measurement & Verification Plan to establish the means of accomplishing it.

Vidaris’ consulting also included recognition and advancement of the project features such as:

  • Superior IAQ, via low-emitting interior finishes (including flooring systems), IAQ management during construction, and sustainable maintenance practices
  • Water-efficient landscaping and stormwater management

Vidaris’ consulting is co-funded by NYSERDA.
