Blue-green roofs have been utilized and studied for their enhanced water storage capacity compared to conventional roofs or extensive green roofs. Nonetheless, research about the thermal effect of blue-green roofs is lacking. The goal of this research is to study the thermal effect of blue-green roofs …

Many nature-based solutions are seen as favourable and effective measures to increase urban resilience during more extreme weather events, by for example decrease high temperatures in summer. Since space is often scarce in urban environments, roofs have received increased attention in mitigating the …

LijnbaanPark improves the environmental quality of the Lijnbaan district in Rotterdam by introducing green rooftop architecture and skywalks, meant to become part of a future pedestrian circulation network above the streets in the city. The Lijnbaan is an icon of modern architecture, and although it …

Green roofs received increased scientific attention with respect to climate adaptation in urban environments for their hydrological, biodiversity and insulative capacities. Yet, the thermal properties of roofs with an additional water layer underneath the vegetation substrate (blue-green roofs) are not …

Online knowledge-sharing platforms could potentially contribute to an accelerated climate adaptation by promoting more green and blue spaces in urban areas. The implementation of small-scale nature-based solutions (NBS) such as bio(swales), green roofs, and green walls requires the involvement and enthusiasm …

Cities are becoming increasingly vulnerable to climate change, and there is an urgent need to make them more resilient. The Climatescan adaptation tool www.climatescan.nl is applied as an interactive tool for knowledge exchange and raising awareness on Nature-Bases Solutions (NBS) targeting young professionals …

Across European cities local entrepreneurs are joining forces in new ways, forming collectives to stimulate business growth and innovation and to create a more attractive business environment. The value of such collectives is increasingly recognized by local governments and policy measures to stimulate …

Increasing urbanization and the effects of climate change will bring new challenges for cities, such as energy saving and supply of renewable energy, preventing urban heat islands and water retention to deal with more frequent downpours. A major urban surface, the surface of roofs, is nowadays hardly …

Urban planning will benefit from tools that can assess the vulnerability to thermal stress in urban dense cities. Detailed quick-scan heat stress maps, as made in this study for Johannesburg, have proven valuable in the decision-making process on this topic. It raised awareness on the urgent need to …
