Name or title of the innovative policy, practice, program, or outcome:
Chilled Beams save up to 57% of energy used in the Integrated Research and Innovation Center (IRIC).

A brief description of the innovative policy, practice, program, or outcome that outlines how credit criteria are met and any positive measurable outcomes associated with the innovation:

Standard laboratories use large amounts of energy to meet the cooling and heating loads in the building. Cooling uses more energy and requires more air than heating which means that the cooling load drives the size of the air system. To reduce the required size of the laboratory air system and associated energy consumption, the UI decided to implement active chilled beams in its newest laboratory building, Integrated Research and Innovation Center (IRIC), which increased overall efficiency.

Active chilled beams push cool air into a room, and circulate warm air in a room across pipes filled with chilled water. This system drives air circulation in the room while cooling the air that has already been delivered to the conditioned space. This active chilled beam systems is helping us to meet cooling and heating load requirements of the lab building (IRIC) with much greater efficiency than common variable air volume (VAV) systems. When compared to a standard VAV system, ASHRAE Journal 2007 claims, “chilled beams in a laboratory can result in a 57% energy saving for that specific system”. Energy savings in lab buildings are crucial, as they are one of our largest energy consumers.
