How can vacant buildings and brownfields be put to good use again? This question is addressed in the technical paper “Overcoming Obstacles to the Revitalization of Brownfields and Vacant Properties” (in German), published as part of the BMLUK’s Brownfield Dialogue. Carmen Dilch from the Real Estate Management Study Programs contributed her expertise in real estate development to the project.

Sustainable Site Development Through the Revitalization of Vacant Properties

This white paper summarizes the current state of knowledge regarding vacant properties and brownfield sites and uses practical examples to highlight the challenges involved in their revitalization. These challenges include, among other things, legal frameworks, financing, building requirements and a lack of land-use and development plans. At the same time, the experts present potential solutions that can facilitate sustainable reuse.

A central aim of the publication is to reduce land consumption and make better use of existing infrastructure. According to the expert panel, the reuse of already developed land can help reduce soil sealing, resource consumption and emissions. Particular emphasis is placed on the importance of interdisciplinary collaboration between the real estate industry, spatial planning, administration and politics.

Interdisciplinary Working Group within the Brownfield Dialogue

An interdisciplinary working group within the Brownfield Dialogue developed the white paper—including experts such as Carmen Dilch in the field of real estate development. The publication was released on the BMLUK website as well as within the framework of the Brownfield Dialogue.
