Building automation links sensor measurements to lighting, heating and other building services. It follows defined rules, for example by occupancy, temperature or time; its effects are assessed against actual building use.
Core automation systems
Smart lighting
Lighting control systems (Philips Hue, KNX, DALI) make it possible to:
- switch lights on and off automatically based on occupancy;
- dim lighting according to the available daylight;
- use scenes (work, meeting, relaxation);
- reduce unnecessary lighting based on occupancy and daylight.
Heating, ventilation and air conditioning (HVAC)
A thermostat compares measured temperature with a setpoint and controls compatible heating or cooling equipment. Some models add schedules or adaptive features, but these are not universal. Zone control allows separate settings for different rooms.
Blind and curtain control
Motorized blinds that respond automatically to sunlight reduce cooling costs and protect rooms from overheating.
Automation protocols
KNX, Zigbee, Z-Wave and Matter are examples of standards and protocols found in building automation. Their architectures and requirements differ. Compatibility is checked for particular devices and features; sharing a protocol does not automatically mean supporting every function.
Economic impact
Automation can reduce unnecessary energy use. Results depend on the building, equipment, operating schedule and settings. Assess savings with measurements before and after implementation, without promising a fixed percentage or amount.
