This project, for New York City’s Department of Cultural Affairs, transformed a five-story historic former public school to better house four arts groups and one community-service organization.

​

Built in 1894, PS 122 was originally a public school (hence the name). Since the 1970’s the building has been inhabited by a non-profit collaborative, daycare center and an AIDS drop in center. The primary objective of this project was to bring the building up to code and upgrade the mechanical and fire protection systems.

​

Additionally the building needed significant reorganization and alterations to its interior spaces.  The design scope included addition at the roof, to connect the means of egress at the fifth floor. The project was required to meet LL86 requirements.

​

Mechanical systems included:

• A packaged air-cooled modular chiller plant designed with an 18-degree temperature difference to reduce pumping and piping

• Variable primary pumping

• A dedicated outdoor air system (DOAS) with energy recovery and demand-based ventilation controls

• Sensible-only 4-pipe fan coils
