The Challenge: A prototype facility to serve communities across the country
In 2009, Banner approached the engineers at SmithGroupJJR to develop a template for prototypical primary care outpatient clinics. The goal of producing this mechanical template was to optimize
future facility planning and operations. Banner Health inquired about Displacement Ventilation (DV) in particular, and SmithGroupJJR supported DV as an excellent fit for Banner Health, given the
organization’s operational values of ensuring maximum comfort and healthy environments for both patients and staff. DV requires less energy and provides higher ventilation effectiveness than
standard mixing ventilation, thereby improving indoor air quality by allowing the natural convective process to isolate contaminated air in the high level unoccupied space near the ceiling.
Due to consistent and industry-leading product support, Price had long ago been identified by SmithGroupJJR as a solid partner for complex projects such as Maricopa, involving relatively new
technologies like DV. SmithGroupJJR involved Price in the design process, where Price assisted in substantiating DV as a viable option for Banner Health projects in several ways:
- Price hosted an operations team from Banner Health at Price Technical Center West, demonstrating mockup capabilities and how DV would function in spaces such as the Maricopa facility.
- Price supplied DV diffusers and heated mannequins, and Banner Health designed and provided instrumentation to enable independent on-site testing alongside SmithGroupJJR in a model of
a sample room. Temperature probes monitored the space from 6" off the floor, with a sensor every 12", up to 6" below the ceiling.
- Banner Health commissioned Price to conduct Computational Fluid Dynamic (CFD) analyses showing precisely how DV would function in the template Maricopa space. Banner’s goal was to make
the most efficient use of space, and thus wanted to use ceiling level displacement supply air diffusers as opposed to traditional low wall outlets. The CFD analyses substantiated that this
would not compromise the effectiveness and benefits of the DV system.
Potential payback schedules based on energy savings were calculated, and this efficiency, along with DV’s significant health and environmental benefits, made DV the perfect choice for this project.
