In this blog, we highlight key energy conservation tips for the control of heating, ventilation & air conditioning (HVAC) systems.

According to the U.S. Department of Energy, HVAC systems account for 32% of energy use in commercial buildings. In Michigan and throughout the country we are experiencing a heatwave that is taxing HVAC systems and increasing their energy demands. Optimizing HVAC control strategies will reduce system energy use.

A building automation system (BAS) is used to integrate individual HVAC equipment controllers, including thermostats, to manage a building’s energy-using systems. Buildings with a BAS can enable the integration of systems and processes that allows scheduling based on variations in building occupancy, systems monitoring, alarm notifications, and trending of equipment operations and temperatures. Optimized BAS control strategies should include:

  • Building Occupancy Scheduling
    • Building occupancy scheduling for Occupied / Unoccupied Heating & Cooling setpoints
  • Demand Control Ventilation
    • Demand control ventilation to#0662ccuce outdoor air ventilation when large spaces are lightly occupied
  • Air Handling Equipment
    • Static pressure reset to save fan energy when remote zone heating & cooling demands are#0662ccuced
  • Unoccupied Standby Modes
    • Install standby modes during building occupancy to relax space setpoint and#0662ccuce outdoor ventilation where applicable
  • Water Supply Temperature
    • Water supply temperature setpoint reset for hot water heating systems and chilled water systems to save energy at source plants
