Legrand’s lighting management systems, which are designed to make buildings more energy efficient, encompass two types of solutions – stand-alone switch sensors and BUS/SCS systems.
“These energy efficient lighting management systems ensure there is exactly the right amount of light when and where it is needed,” says Luk Ivens, general manager, Legrand Southern Africa. “Lighting, together with heating and air-conditioning, accounts for the greatest energy consumption and electricity costs of a building. With the installation of an automatic lighting management system, energy savings of more than 30% can be achieved. These savings are increased to about 55% with the addition of occupancy sensors.
“Reduced lighting usage not only lowers operating costs, but also helps decrease Green House Gas (GHG) emissions. Additional savings include reduced lamp replacement and maintenance requirements and lower power demand during peak hours.
“Because various areas in a building need different lighting control strategies, we recommend a number of solutions to maximise energy savings and to ensure absolute comfort for occupants of the building.”
Legrand’s switch sensors are designed to efficiently manage single or multiple areas in an installation. These ceiling, corner and outdoor switch sensors can operate in occupancy and vacancy mode and use passive infrared technology (PIR), ultrasonic or dual technologies. A daylight set point feature keeps the lighting off when the natural light level rises above a pre-set level. This setting is adjustable and can be over-ridden.

The BUS/SCS solution for lighting management – which consists of a control unit, SCS (simplified cabling system) sensor, room controller, dimmer and software – manages a single floor, or a whole building, with actuators or dimmers, communicated by means of the BUS. Every installation is designed, monitored and supervised on a PC, using Legrand’s advanced software.
Where a room is fitted out completely in glass and the BUS/SCS system is not suitable, a wireless Radio/ZigBee control unit should be installed at the door. A control unit enables lighting to be efficiently controlled from a PC.
The Legrand Group, which is moving towards a more sustainable way of designing, constructing and renovating buildings, is committed to the framework for the development of Green Buildings.GreenBuildingis an approach to a building that considers the overall environmental impact of a building, as well as the health and well-being of its occupants.
Legrand’s lighting management systems have been designed and manufactured to meet quality, safety, energy efficiency and budget needs throughout the world. By installing lighting management and other automated controls, energy waste is avoided and the building only consumes just the amount of energy it needs, when it needs it.
