Buildings are responsible for over 40 percent of the world’s total energy consumption and about 25 percent of the world’s CO2 emissions. Smart building technologies are being used to optimize their energy usage, helping to reduce the environmental impact. One such technology is ABB’s i-bus® KNX devices, which are used to control a host of operations in buildings, including lighting, heating, and security. By responding to insights gained through data collected by numerous sensors these intelligent devices help bring energy savings as much as 30 percent, when compared to conventional non-automated systems.
For example, presence-controlled lighting sensors that automatically switch off the lights in rooms and common areas after a certain period of inactivity consume much less energy than by depending on a person to turn off with a mechanical switch. These intelligent devices from ABB help to only use the energy actually needed. The ABB i-bus KNX offering also includes devices that help to monitor and optimize energy use by measuring the energy consumption and collecting and analyzing consumption data.
These digital and connected devices use KNX, a worldwide standard for home and building control. All components in an electrical system of a building are interconnected and can even be controlled remotely, through a smartphone or tablet. The devices are being used across all types of buildings, from homes and offices to hotels, hospitals and even stadiums, providing ease of operating along with energy and cost savings.
