The University of Arizona

The University of Arizona sought to reduce operating costs over the life of its new cancer center on the Phoenix Biomedical Campus, and the project was required to obtain a minimum of LEED Silver certification. The active chilled beam solution chosen for the project requires less energy to operate, required 67% less air handling equipment and ductwork, and provides a draft free environment suited to cancer patients undergoing extensive daily treatment. However, the characteristic soundlessness of chilled beams is not ideal for spaces in which confidential conversations are taking place. Sizing down one component of the supply air sequence in the chilled beam technology created sufficient audible turbulence to mask conversation throughout the exam rooms and infusion bays without compromising building energy performance.
