Commissioning Testing of the VAV Diffusers and PV

Alonzo Blalock, P.E., Jacobs Engineering
The project included installation of VAV Diffusers for the floor spaces. The project was to
demo all ceiling and ductwork and the AHU on a 2 floor area, starting at the top floors. Then
installation of new duct and the VAV diffuser system. Multiple testing runs were made of the
initial installation to arrive at a suitable control arrangement and testing pattern.
Commissioning for the varied operations required development of a different testing regimen
than had been typical for VAV systems. Tracking of the PV output with the BAS system is available to the Regional office in Ft Worth.
