New York, New York, USA
The renovation of New York University’s (NYU) Rubin Hall, anticipated to be the among the largest Passive House EnerPHit retrofits in the world, sets a powerful precedent for decarbonizing existing historic buildings across the United States. The all-electric retrofit demonstrates how landmark historic buildings can be sensitively transformed into high-performing, energy-efficient projects prepared for the next century. The project is a formative step to address NYU’s Climate Action Plan and is an exemplar project for the retrofit of millions of square feet of pre-war multifamily construction in New York.
New York University Rubin Hall by FXCollaborative Architects, received an 2025 American Architecture Honourable Mention from The Chicago Athenaeum: Museum of Architecture and Design.
Located in New York City’s Greenwich Village, Rubin Hall was built in 1926 as a hotel. It was purchased by NYU in 1964 for use as a student residence and designated as contributing building to the Greenwich Village Historic District 1969. Like many pre-war buildings in New York, its Neo-Federal structure consists of structural steel columns and beams, cast-in-place concrete floor slabs, and an uninsulated red brick and terracotta block exterior. These construction methods, once common, now present significant challenges for energy efficiency and occupant comfort, making the transformation of Rubin Hall an important model for future retrofits.
Prior to renovation, the building was one of the few student residences in NYU’s portfolio without air conditioning in student rooms, which became increasingly problematic with recent heatwaves. The building’s systems were antiquated and inadequate to meet today’s needs. Oil-fired boilers supplied, steam radiators which were sized to overcome heat loss through uninsulated walls and windows which often caused overheating. Windows provided the only ventilation in the building, causing either poor air quality when closed for comfort, or energy inefficiency when open for fresh air on hot or cold days. The decision to retrofit was driven by NYU’s aggressive Climate Action Plan, which pledged to reduce building greenhouse gas emissions and reaching carbon neutrality by 2040.
The retrofit of Rubin Hall employs innovative solutions to enhance performance while preserving its historic character. All new mechanical, electrical and plumbing systems are seamlessly integrated through existing shafts to maximize usable space and minimize construction cost. All-electric heat pumps, Dedicated Outdoor Air System (DOAS) units with energy recovery, and an emergency generator are discreetly positioned on the roof to minimize views from the street in accordance with NYC’s Landmarks Preservation Commission guidelines.
A major challenge was upgrading the building’s windows—critical to both its historic character and Passive House performance. The solution was custom-designed, triple-glazed, simulated double-hung windows that replicate the building’s original aesthetic while providing cutting-edge thermal efficiency. The design team collaborated closely with the window manufacturer to develop a product that not only meets Passive House standards but also serves as a scalable solution for future historic retrofit projects.
Beyond its energy performance upgrades, the renovation revitalizes Rubin Hall’s interior while enhancing student living. A historically sensitive restoration of the original lobby preserves its architectural grandeur, while new student amenities on the second floor and fully renovated student rooms introduce modern finishes, improved layouts, and enhanced accessibility. Durable, best-in-class materials—selected for occupant health and sustainable manufacturing—ensure a long-lasting and environmentally responsible environment.
