HVAC Control

Pains & drivers

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
