The question, addressed by this project, is how to cost effectively save space conditioning energy and dollars in buildings with ducted constant air supply systems, particularly since many of these older central city buildings are 50% or less occupied. The problem for these older systems is how to design a low cost VAV system.

CBEI researchers worked with a local HVAC contractor to test a unique approach to this problem and determine the energy performance of a potential low cost option.
