Research green roof in Leipzig, Germany

Abstract

Due to the progressing climate change, cities face the challenge of adapting to new weather conditions, including heavy rains and draught periods. Green roofs are considered a promising solution for sustainable urban development, as they require no additional space and are expected to offer multiple functions. These include rainwater retention and storage, cooling effects, provision of additional space for humans and animals, and functioning as sink for urban pollutants. To validate these functions, a Research Green Roof was constructed on a building at the Helmholtz Centre for Environmental Research campus in Leipzig. The Research Green Roof consists of four roof 80 m2 segments: extensive and semi-intensive green roofs, a wetland green roof, and a gravel roof serving as a reference. Each segment is equipped with numerous sensors to monitor water and heat balances. Additionally, botanical and entomological monitoring equipment has been installed. The roof segments are the subjects of interdisciplinary research by several working groups. This publication presents the research infrastructure and provides an overview of the ongoing studies.
