Building Automation  

Air handling unit (AHU) supply air static pressure and temperature resets are advanced control strategies that can save significant building energy in partial load conditions and are required by energy codes. In this presentation, we will introduce the AHU pressure and temperature reset concepts, describe different implementation options, and recommended AHU static pressure reset control setup. Industry best practices on implementing these resets will also be introduced.

Optimal scheduling, including shorten HVAC schedule, wider zone temperature setpoint deadband, and optimal start/stop, can achieve significant energy savings with low implementation cost. In this session, the concepts, application, and design of optimal scheduling will be introduced, including different HVAC system control modes: warm-up, cooldown, setback, and setup. Factors impacting the optimal start recovery time will be discussed, and optimal start implementation examples will be given.
