Our mission is to use green solutions to make the city more sustainable, healthier and more liveable. We focus on 5 main themes: Biodiversity, Water Management, Urban Heat Island Effect, Sick Building Syndrome and Well-being. For these themes, we use green solutions to: - promote biodiversity - combat global warming - rainwater (re)use - improve the indoor climate In order to be able to offer these solutions constructively, Van der Tol works with an integrated approach. This approach can be found in a mini-Ecostad in Berkel en Rodenrijs. A reference project that has been successful for several years and is continuously developed with sustainable innovations. If you would like to know more about all technical applications, please do not hesitate to contact us. Taking steps towards an integrated approach is only possible by participating in cooperation. Van der Tol works together with, among others, the following parties: NL greenlabel, Cirkelstad, Leven op Daken, Co Green, The Healthy City, Amsterdam Rainproof, Griffioen Wassenaar, De Vlinderstichting and Rooftop Revolution.
