Energy Efficiency
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
