A School Gym That Blocks the Train, Not the Daylight
At PS19 in Queens, the #7 train runs directly beside the school. The new gymnasium needed broad daylight for play, a dependable acoustic barrier, and a fast installation that worked with precast—without turning the court into a glare problem.

PS19 students use the bright gymnasium: a court designed for usable, even daylight rather than distracting hot spots. |
The Challenge: Daylight Beside an Elevated Train
PS19 is a densely urban school project where the building envelope had to solve more than an opening for natural light. The gymnasium sits beside the #7 line, which made acoustic comfort a central part of the façade decision. At the same time, vision glass could introduce the bright patches and glare that interfere with court lines, player movement, and daily use.
Three Constraints, One Façade Decision
The project team needed an envelope that could support a fast precast construction sequence, limit the impact of the adjacent subway environment, and deliver diffuse daylight instead of direct sun. Separate treatments for daylight, sound, and thermal performance would have made an already compressed build more complicated.

PS19 beside the elevated #7 subway line—the urban condition that made acoustical performance part of the daylighting decision.
The Solution: One Envelope Component, Multiple Jobs
MBB Architects chose Solera® to give the gymnasium a controlled daylighting component that worked with the precast grid. Rather than using vision glass and attempting to correct its side effects later, the team used diffusion to distribute daylight through the activity space while retaining the robust envelope performance the project needed beside the train.
Diffuse Light Without Court-Level Distraction
Solera® spread daylight through the gym instead of concentrating it into glare and hot spots. It also created the horizontal ribbon effect the architects wanted, while supporting the daylighting, acoustical, and thermal objectives in one façade strategy.
The Proof: A Court Students Can Use All Day
The gym is used for school-day instruction, after-school activity, and weekend sports. That makes visual consistency more than an architectural preference: the court needs to be readable and comfortable whenever students use it.
The outcome was a gymnasium where daylight supports the game instead of competing with it. The design team also noted that the electric lights can remain partly or fully off during the day for most activities, reducing the gym’s lighting-energy demand while maintaining a functional court.

The completed PS19 gymnasium: a clear, even court environment designed to avoid daylight hot spots and preserve visibility for play.
The Lesson for Urban Schools
When a school sits beside infrastructure such as an elevated train, daylight cannot be specified separately from the rest of the envelope. The right approach is to model the light, understand the urban constraint, and specify a daylighting component that can support visual comfort, practical installation, and the broader performance required of the wall.
