Chin Lin explains how using displacement ventilation as an alternate to air conditioning can reduce capital costs with the added benefit of superior indoor air quality in this article for School Planning & Management.
“With building committees aiming high to achieve greater impact in sustainability, design teams are researching and benchmarking unconventional solutions beyond the LEED checklist. For several public schools built in the northeast, this quest led to a bold break from convention. These schools rely on dehumidification displacement instead of air conditioning for cooling classrooms and other student spaces. The savings are significant: a reduction of at least 25 percent in energy consumption and cooling system use over a conventional fully air conditioned, variable air volume system.”
