Charity shop vindingrijk (Breda, the Netherlands)
Frans van der Meulen, Head of Technical Services at BSW Bedrijven: “As an organisation we are all for sustainability and making our organisation greener, but we must never forget to strike the correct balance between social and commercial needs. Our green investment must be profitable. Plus, in a shop you have to have good lighting. We needed custom work for each part of the shop floor.”
The initial situation? A second-hand shop with an adjacent warehouse. No daylight available except for some windows and one single light dome (standard dome). Conventional, not yet energy-efficient lighting.
The solution? 1 LightCatcher per 55 sqm of floor surface, neatly integrated into the lowered ceiling with custom-made light shafts. New lighting was also fitted at the same time. High-frequency fixtures that can be operated individually on the basis of the light strength on each tile of the floor.
The customer’s verdict? F. van der Meulen: “Our shop has a sheltered workshop for people with a disadvantage on the labour market. They put all the LightCatchers together themselves and that went really smoothly. The reactions are unanimously positive. It is no longer as warm and the light is pleasant. The shop looks bigger and there are far fewer shadows. Above all, the light continues to shine throughout the year. Because of its curved shape, the dome doesn’t become dirty. We haven’t yet had to clean it once.
The LightCatcher is a fantastic concept and not at all expensive. The cost-recovery period is around four to five years but I expect it to last for at least 20 years. We are going to buy more. We have plans for a few offices, a meeting room, but also a production facility, because there the LightCatchers can be used to their full potential. On top of the energy savings there is also more of a sense of wellbeing on the shop floor and therefore less sick leave.”
Facts and figures
|Before:||All lights were on because there was not enough daylight available.|
|Plus ventilation in summer because the lamps gave off too much heat from the low ceiling on the first floor.|
|After:||The lights are off for on average up to 10 hours a day (controlled by the daylight monitoring system) and ventilators are no longer needed.|
|Annual savings thanks to the LightCatcher:||42,978 kWh (calculated at € 6,059 in savings per year).|
|Annual reduction in CO2 emissions:||33 tonnes.|
