          Application: HVAC Control


          Pains & drivers



          HVAC Control applications include products, systems and services aimed at controlling HVAC equipment in order to:
          • Provide required environmental conditions (temperature, air displacement speed, moisture, CO², etc) for occupant’s comfort and building efficiency
          • Minimise energy consumption
          • Reduce other costs, such as operation, maintenance and repair costs

          How can a customer manage energy more efficiently?

          • HVAC can represent up to 70% of energy consumption depending on segments.
          • Different methods can be combined to save energy costs for HVAC in a range of 15% to 30%:
            - Program temperature set point according to occupancy
            - Adapt heating or cooling production power according to real building needs
            - Raise temperature to comfort level when occupant presence is detected
            - Adapt ventilation flow according to occupancy or internal air pollution level
            - Recover heating or cooling energy from extracted air

          Solutions or architectures used in the application

          • Stand-alone control products are used for local or central control (time switches, thermostats, clock-thermostats, stand-alone controllers).
          • HVAC control systems permanently provide each area with optimised environmental conditions.
          • Building Automation Control Systems control HVAC among various functions, such as lighting control, blind control, or security.
          • Energy services enable systems to secure year-round maximum savings and high comfort level for occupants. Energy services can include:
            - Engineering services
            - Commissioning
            - Maintenance
            - Energy reporting
            - Monitoring & Targeting
