Idealis has appealed to students to eat together more often. It saves energy. So does taking shorter showers, using the stairs and wearing thick socks.
The main thing, according to Van Dijk, is not just to save energy directly by switching off equipment you are not using, for example. ‘Using material sustainably is important too. For example, by cooking together instead of individually and one after the other, by making one-pot meals, and by using seasonal local vegetables.'
The campaign follows steps taken by Idealis to bring down energy consumption in the student residences. By installing new boilers, water-saving taps and above all by using energy-saving building materials, Idealis has brought down consumption by 10 percent. Now it is the students' turn.
From mid-December, students will be able to keep track of how they are doing. Van Dijk: ‘We are going to work out the consumption figures for each residence. This won't be the overall consumption but the actual use by residents.'
