The conceptual design by Stanley Mumma does not circulate indoor air through the temperature control exhaust system in the manner of typical variable air volume (VAV) systems; it provides a steady stream of outdoor air that has been cooled to remove humidity. The engineered system brings the outdoor air into the building via dedicated ducts at a lower speed than in VAV systems, which ASME International says allows for a balance in the relative pressures between rooms and no infiltration of air from one space to another.
The organization also reports that the radiant cooling system uses a building’s overhead sprinkler plumbing to deliver cool water to aid in temperature control. The Dedicated Outdoor Air System has been installed on an experimental basis in a 3,200-square-foot building on the Pennsylvania State University campus in University Park.
