The Medisch Spectrum Twente (MST) is one of the largest clinical teaching hospitals. Around 3,500 employees are dedicated to promoting health in the Twente region in close cooperation with regional partners in the healthcare sector. The main location in Enschede is a modern hospital. Technological innovation, efficiency and sustainability are aspects that play a major role in MST on a daily basis, and not only in the medical field. In 2020, the car park at the Enschede site was converted to connected lighting. This means that precisely these aspects can be ensured in the area of lighting. Both the car parks and the stairwells were equipped with STEINEL lights that come on precisely when they are needed. Measurements showed that the previous 24-hour lighting was on for 7,368 unnecessary hours over a period of one year – an extraordinary number that had to be reduced as quickly as possible. By converting to connected lighting, MST has taken an important step towards minimising energy costs while also ensuring that visitors feel safe.
