Energy is always top of mind for us. We invest in technical innovations that generate energy sustainably. A good example of this is the Daylight Greenhouse. Special lenses in its roof concentrate the rays of the sun onto a tube containing running water. This heats the water which can then be stored. The heat can either be used to warm the greenhouse straight away or at a later time, for example at night or in winter. This cuts our energy consumption by 40–50% compared with a conventional greenhouse. We also use solar panels, LED lighting and a ground-coupled heat exchanger. We’re also affiliated with a heat cooperative that develops geothermal energy.
