Cohn, L

Building design and use determine how quickly retrofitted variable-air-volume (VAV) systems will pay for themselves, but buildings with large central systems will experience the largest increase in efficiency. Payback variables include the design and size of the original air-handling equipment. Converting from a constant-speed to a VAV system offers the choice of discharge dampers, inlet vanes, bypass controls, and variable-pitch vanaxial fans to shut off parts of the system according to the season. Examples of VAV retrofits illustrate the modifications and savings that are involved. (DCK)
