Alfred A. Arraj U.S. Courthouse (Denver, CO)

A displacement ventilation system in the courtrooms of the Denver Courthouse features low-velocity air introduced at the floor level to efficiently condition the space and remove indoor air pollutants. An early concern about cooling the courtrooms led to a heat load test to demonstrate system performance. The U.S. Courts are now quite pleased with the under floor air, particularly with how quiet it is.
