KaDEr Gelderland – Karakteristiek Duurzaam Erfgoed

Characteristic & Sustainable Heritage Gelderland

The province of Gelderland has an enormous heritage asset, ranging from country estates and monumental churches to traces of the Second World War. With the transition to more sustainable heritage, not only the interests of individual owners, of municipalities and of provinces play a role. The overarching social value is key: heritage, too, must contribute to a future that is no longer dependent on non-renewable energy sources.

The KaDEr-project was prompted by the troublesome heritage policy, which was not effective to create added value through sustainability. The project is organized around four Living Labs and eight individual sub-projects are executed. All Living labs included MSc design studios. The questions for the Faculty of Architecture and the Built Environment are therefore: what should the focus of heritage policies be? How can the transition to more sustainable heritage be included in the policies and how can existing procedures be improved? The outcome are changes in policy, new ways to define criteria for subsidies, evaluation of tools to promote sustainability broadly considering energy, use, feasibility and learning practices. The portal of the Erfgoed Alliantie in Gelderland shares all the documents and project results.
