Sustainability ranks high on our agenda and is an indispensable part of our mission. We took a major step in sustainable energy use when in 2017, we connect our heating system to the Hermitage Amsterdam. Yes, their art warms our plants! The museums air-conditioning has to maintain a constant, cool and dry temperature. The redundant warmth is transported to the Hortus to heat our greenhouses. The resulting cold is transported back to the Hermitage. Over 2017 and 2018 we have cut back our CO2-emission with almost 480 tons.
We want to take our sustainability goals some steps further. In 2023 the thoroughly renovated Three Climate Greenhouse is a sustainable home of biodiversity. The current glass windows will have been substituted by insulating, double glass. The roof will be covered with a transparent, insulating ETFE foil.
On the interior, the collection will be organised in a way to optimise care en maintenance. Hi-tech climate regulation, heated soil and circular water use will create ideal, sustainable growing conditions. Day in , day out, in every season.
