Synopsis This paper describes an approach to the automation of the commissioning of HVAC systems. The approach is based on software that generates a sequence of test signals to exercise systems while under closed-loop control. The test signals are in the form of setpoint changes that exercise considered systems at strategic operating points. The software contains simple models, which are used to select the setpoints in the test sequence. Indices, calculated over a predetermined monitoring period following each change in setpoint, characterize system performance. These indices are compared with ideal values in order to assess performance and diagnose important commissioning faults. The paper presents results from testing the approach on a simulation of a dual-duct air-handling unit installed in a federal building in San Francisco.
