In public buildings lighting accounts for about 40% of the electricity costs. If you multiply this figure by the number of kindergartens, schools and universities, town halls, local government buildings and government departments, libraries, swimming pools and hospitals, then the total is enormous. Lighting in public buildings is currently consuming far more energy than necessary, with all the negative side-effects such as high running costs, electricity bottlenecks and damage to the climate. That can easily be changed.

The true cost of cheap products: The city hall employees had put up with poor lighting at their workplace for far too long: gloomy corridors, flickering fluorescent lamps, and no emergency lighting or outdoor lighting. And the monthly electricity bills were enormous. Finally, it was decided that the building has to be renovated. A lighting expert analysed the status quo, produced a new lighting strategy, and drew up a plan to implement this.
