Utrecht University a little darker

Turn off the lights! On Saturday 25 March, it is the sixteenth time households and companies all over the world are asked to turn off their lights between 8.30 pm and 9.30 pm. With this initiative, the World Wide Fund for Nature raises awareness for nature on Earth. So what does the university do to achieve reduction and sustainability of lighting on campus? And what can still be improved?  At Utrecht University a lot of people work on sustainability and energy issues in many different ways. In research and education, but also in business operation. Including sustainable catering , waste separation , future-proof buildings , enhancing biodiversity on and around the campus (also see: Meet the nocturnal animals of Utrecht Science Park ), circular procurement , reducing the CO₂ footprint , efficient use of water, energy saving and transition and new travel policy. All sounds great, but to get back to lighting: why do some Utrecht University buildings still have lights on in the evening and at night?. Peter Prins , Advisor on Energy and Sustainability: Lights are indeed turned off as much as possible, but some education buildings and for instance libraries are still open in the evening.
