Smart Home Energy Savings: Lower Your Bill with KNX

Is KNX energy saving really possible?

Yes. A KNX-based system can save 20 to 30 percent on lighting energy, 15 to 25 percent on climate, and 15 to 20 percent on the total electricity bill. These figures are based on field studies by the European KNX Association and long-term industry data. The actual saving depends on the property size, insulation quality, and depth of automation.

The source of savings: sensors and scenes

Presence sensors turn lights off automatically when a room has been empty for 10 minutes. Daylight sensors dim lights near windows when the outside is bright enough. A KNX thermostat with sensor lowers the temperature in empty rooms and keeps only occupied areas at comfort level. Each of these seems like a small gain on its own, but added up over a year they reach thousands of lira for a villa.

Multi Sensors

Mid-Range KNX Presence Multi Sensor w/ Thermostat - White

A unique combination of safety, efficiency, and comfort with the thinnest design in its class. With the new Interra KNX Sensor Series with Thermostat, functions like energy and lighting management, heating, and air conditioning in indoor spaces can be integrated into building automation systems in an innovative and reliable way.

DALI integration in lighting

When KNX is combined with DALI-2 lighting control, each fixture can be addressed and dimmed individually. In a living room, as daylight increases, the artificial light slowly dims while the level stays constant. The user does not notice, but the meter does. The high number of sunny days in Antalya makes DALI-based lighting automation especially effective.

DALI-2 Devices

KNX - DALI Gateway (1x64 DALI)

A unique lighting atmosphere with maximum flexibility! ITR832-0001 is a one-channel KNX-DALI interface device used to provide an interface between DALI and KNX installations, enabling communication between the two protocols.

KNX energy monitoring

Energy consumption can be monitored in real time over KNX. Solar panel production, power drawn from the grid, and the home's instant consumption all appear on the same panel. This data shows which devices use how much power and allows informed decisions. For villa owners in Antalya investing in solar, KNX energy monitoring is a critical tool for balancing production and consumption.

How much do you save?

A calculation: a 300 m² Antalya villa with an average monthly electricity bill of 5,000 TL. A 20 percent saving means 12,000 TL per year. The payback period for a KNX system through energy savings is 5 to 7 years. Since the system life exceeds 20 years, the remaining 13 years are net savings.
