Delft has gained an extra polder. Right in the centre of TU Delft campus the flat roof of the faculty of Civil Engineering and Geosciences (CEG) has been transformed into an active water storage facility. The green roof serves as a research and testing site for urban farming and is good for energy savings through isolation and sustainable use of materials.
The polderroof is a concept of the company Metropolder Company (formerly Polderdak). The fieldlab polderroof is established in a partnership between Stowa, the Water Board of Delfland, Rioned, the municipality of Delft and the TU Delft. The fieldlab consists of two roofs - the polderroof and the conventional roof next to it for reference.
In the beginning of September 2018, the TU Delft received an additional funding of 270k for the realisation of the polderroof from the Climate KIC project. This grant will be used for new research related to the subject of urban farming and the saving of energy. The results of this research will also be interesting for other countries.
TU Delft sees the polderroof as a great asset for research on the water management area and a very good example of innovation and sustainability. Entrepreneur Friso Klapwijk is busy with the realization, but in the meantime already thinking of the future: “In addition to the experiments on the polderroof in Delft, we are extending the research to Italy, where the polderroof will be tested at locations in different climatic conditions. The results from these experiments will help us fine-tune the polderroof design and develop new business cases for countries with other climates.”
