Optimizing HVAC Control to Improve Building Comfort and Energy Performance
Abstract
This paper demonstrates the benefits of optimal
control in well-designed and operated buildings using
a case study. The case study building was built in
2001. The HVAC and control systems have been
installed with state-of-the-art equipment which
include a terminal box temperature integrated
minimum airflow reset. The building has been used
and operated based on the design intents. This paper
presents both the existing and the optimal control
schedules, which include the VAV box operation
schedule, AHUs optimal control, chiller and chilled
water pump control, and boiler and hot water pump
control. The measured hourly HVAC electricity
consumption shows that annual savings of up to 40%
can be achieved with an optimal control schedule.
