GasTerra is a Dutch company which buys and sells natural gas. It has been the main supplier of gas to the largest companies in the Netherlands for over 50 years. It is currently the largest company of this type in the European Union. Its modern office in Groningen has more than 100 employees. Our task was to supply the company's headquarters with comprehensive office lighting. We equipped each space with luminaires designed to meet the requirements of every room, which are highly efficient and save a significant amount of energy. The final result was an ergonomic office which makes it easier to work more effectively.
