The TU Delft Library uses subterranean storage for thermal-energy cooling. During the summer, the relatively cold groundwater is used to cool the building. Heat is provided by TU Delft’s cogeneration plant.

The TU Delft Library was one of the first construction projects in the Netherlands to be designed on the basis of a comprehensive vision of sustainability and innovation. The building comprises three important ‘green elements’: the green roof, cold storage and climate façades.
