There is currently a big push in the industry to improve energy efficiency and decarbonize lab facilities. One way to do this is to scrutinize air change rate requirements by relying less on established rules of thumb and more on analysis based on the unique needs of the facility.

Not only does the positive buoyancy of the supply air work against the air distribution system, but most overhead mixing systems are designed with low supply air volumes (relative to cooling) and high supply air temperatures (more than 15°F above room temperature).
