Excellum: light controls, energy savings and comfort
Excellum, which specialises in building lighting control systems, is the youngest member of the ETAP group. Excellum aims to minimise the energy usage of new or existing lighting schemes and at the same time increases the visual comfort. Excellum offers an energy management system that is compatible with any lighting system, regardless of type or brand. In addition, Excellum provides a full service, from specification and configuration through to commissioning and maintenance.

Energy & Light Manager (ELM)
The energy management system is called ELM, Energy & Light Manager. ELM is an advanced addressable control system that permits a energy saving up to some 75 % and optimises the light quality at the workplace. Moreover, it is easy to design, install and use. The cost recovery time starts from the first hour after putting into service.

The luminaires, operated by ELM, are addressable and dimmable. This can be done in analog form – via a special interface module – or in digital form – through the use of DALI ballasts. The combination of addressable luminaires and user-friendly software enables ELM to quickly respond to the ever-changing lighting needs in a building. So you get the right amount of light in the right place and at the right time. This is ensured by six control strategies that are integrated into ELM. Energy that is wasted by lighting is virtually eliminated with ELM: lighting will from now on be an integral part of your energy control strategy.
