Summary

Building tuning has long been recognised as a critical method for the improvement of the performance of existing buildings. However, the estimation of the potential benefits of HVAC control adjustments is difficult using normal industry calculation methods. Fortunately, with recent advances in building simulation models, it is possible to test a number of common tuning strategies to determine their effectiveness in achieving energy savings. Based on a generic mid-sized VAV building, the authors have used an IES simulation model to assess the impacts of a number of common control algorithm adjustments, including dead-band and proportional-band adjustments for VAV terminals, fan control and supply-air temperature control, economy cycle and minimum outside air control. Results are repeated for Sydney, Melbourne, Brisbane, Canberra and Darwin to show the way energy impacts change with climate. Combined scenarios are used to show that the difference between best practice and poor control can range as high as 90 per cent, demonstrating the fundamental importance of control. Sensitivity to control is considerably greater in milder climates.
