Chavez and Tubman Halls
and East Dining

Project overview

Originally delivered as the Toll Drive Residence and Dining project, this development expanded Stony Brook University’s on-campus housing through a high-performance mixed-use facility integrating student residences, dining, and shared student spaces. The approximately 350,000 square foot complex accommodates approximately 760 students within two residence halls supported by a full-service dining facility and a variety of flexible study and gathering areas designed to support student life.

Sage Engineering Associates, LLP provided mechanical, electrical, plumbing, and fire protection engineering services for the project. Building Information Modeling was utilized throughout the design process using Autodesk Revit to support multidisciplinary coordination and efficient project delivery. The integrated BIM workflow allowed the design team to coordinate building systems within the dense architectural layout typical of large residence hall and dining facilities while maintaining constructability and maintainability of major building systems.

Student rooms are conditioned using an energy-efficient hydronic valance system that provides quiet, draft-free heating and cooling with individual room temperature control. Central mechanical systems include a 1,000-ton chilled water plant serving the residential and dining areas, while building heating is supplied from the campus high-temperature hot water distribution system. Dining and common areas are served by zoned air handling systems designed to respond to varying occupancy conditions, with ventilation systems incorporating energy recovery to improve overall system efficiency.

Electrical infrastructure for the project includes a dedicated 3,000-amp, 208/120-volt service serving the residence halls and a separate 2,000-amp, 480/277-volt service supporting the dining facility and central mechanical plant. Emergency power is provided by a 1,250 kW standby generator serving life safety systems and critical building operations. Plumbing systems incorporate low-flow fixtures and high-efficiency domestic hot water generation to reduce water and energy consumption.

The completed project achieved LEED Silver certification under LEED BD+C: New Construction (LEED 2009), reflecting a coordinated design approach focused on sustainability, energy performance, and long-term operational efficiency.
