Engineering for Resiliency and Revitalization at PS 320X in the Bronx
By Asrar Abdul Wasay, LEED AP BD+C
Designing Samara Community School (PS 320X) in the Bronx Engineering for Resiliency and Revitalization at PS 320X in the Bronx presented a layered challenge — deliver a high-performance, future-ready facility for 458 pre-K through 5th grade students, support broader neighborhood redevelopment, and meet the rigorous requirements of the NYC School Construction Authority Green School Guide.
The 61,672-sf, five-story school renovation was also an opportunity to redefine what resilient, energy-efficient school infrastructure could look like in New York City.
IMEG, the MEP and fire protection engineer, faced the challenge of balancing aggressive energy targets with operational durability. One solution was using dual energy recovery wheels within the air-handling units to maximize latent and sensible heat capture. Using advanced unoccupied modes allowed 100% air recirculation during off-hours, significantly reducing energy consumption without sacrificing comfort. To address cold-climate exposure, 30% glycol loops and dedicated chemical treatment provide freeze and corrosion protection, extending equipment life.
IMEG engineered resiliency into every layer of the HVAC system. Supplemental electric unit heaters and dedicated split heat pumps protect mission-critical spaces such as telecom rooms and elevator machine rooms. A multi-station gas detection system adds proactive risk management.
Electrical and low-voltage infrastructure presented an opportunity to design for both present-day instruction and future adaptability. Dual cabling backbones—separating instructional technology from building automation—ensure robust classroom connectivity while enabling seamless system integration. High-bandwidth fiber, demand-response metering, and automated lighting controls reduce operational costs and support evolving sustainability initiatives.
Life-safety systems were engineered to exceed baseline requirements. A fully addressable fire alarm system integrates elevator recall, HVAC shutdown, smoke purge, and central station monitoring, while intrusion detection, surveillance, and emergency communication networks provide comprehensive building security.
The project also required thoughtful integration within a broader three-block redevelopment aimed at reconnecting the West Farms community to the Bronx River corridor. Engineering decisions supported this mission through high-efficiency systems, water-saving plumbing, abundant daylighting, and low-VOC materials—contributing to a certification equivalent to LEED Gold.
Completed in early 2024, the $52 million facility earned ACEC New York’s highest award for engineering excellence — a Diamond award in the Building/Technology Systems category — by demonstrating how strategic engineering—focused on energy recovery, lifecycle reliability, advanced safety systems, and scalable infrastructure—can transform a neighborhood school into a resilient, adaptable asset for decades to come.
