The NCH Bonita Freestanding Emergency Department is a 41,000 square foot, two-story medical facility which includes a 24/7 emergency room and outpatient imaging center on the first floor and physicians' offices and an outpatient surgery center on the second floor. Tom Barrow Company was involved with the NCH Bonita FSED project from the initial design through its completion.

The operating room design was a challenging part of this project, with two light/equipment booms within the “critical zone” of coverage for the operating room table. The critical zone of coverage is defined as the area of primary supply diffuser extending 12” beyond the footprint of the table on each side. With no more than 30% of this area used for non-diffusers – lights, gas, equipment booms, etc. (ASHRAE 170 -2017 – 7.4.1b), a standard design with a hard ceiling and individually spaced laminar flow diffusers would not meet the 70% diffuser coverage requirement at the OR table.
Tom Barrow Company worked with the engineer to present a solution using the Price Ultrasuite® OR Ceiling system. The product offered a customizable air distribution and lighting solution specifically engineered for hospital operating rooms. This product provides close to 90% perforated diffuser area. With the high percentage of diffuser area in the “critical zone,” the engineer was able to meet the 70% coverage requirement defined in ASHRAE 170.
Instead of individual ducted diffusers, the Price Ultrasuite® is a plenumized system with 1-2 inlet duct connections. The diffusers integrate high-output LED lighting combined with precision equalized laminar airflow which eliminates the traditional “light ring,” opening valuable ceiling space for surgical equipment while optimizing contaminant removal from the surgical zone. Conforming to all ASHRAE 170 requirements, Ultrasuite® was the perfect combination of performance, aesthetics, and efficiency for this project.
The HVAC system utilized six Temtrol Roof Top Units. These fully custom units included continuously welded aluminum tread plate recessed floors with drains and perimeter lip, factory mounted Yaskawa multi-VFD panels, LED marine lights, and a FANWALL design for system redundancy. One of the units also included a desiccant energy wheel to transfer moisture from the supply air stream to the return air stream to help with dehumidification.
The design of the building included Custom Temtrol Rooftop Air Handling Units, Price Venturi Air Valves, Price Terminal Units, Price Air Distribution, and two state-of-the-art Price UltraSuite® Operating Rooms. Tom Barrow Company was able to package these items along with Loren Cook Exhaust Fans, Ruskin Louvers, and Ruskin Life Safety Dampers to provide the customer and end user with a single source and single contact for all equipment and materials.
