According to a governmental decision, all (re)constructions in Dutch cities starting by 2020 have to be climate resilient. Part of this climate resilience is also adaptation to (extreme) heat. Although urban heat, its causes, consequences, and potential adaptation measures, have been extensively studied …

Since it is insufficiently clear to urban planners in the Netherlands to what extent design measures can reduce heat stress and which urban spaces are most comfortable, this study evaluates the impact of shading, urban water, and urban green on the thermal comfort of urban spaces during hot summer afternoons. …

Small urban water bodies, such as ponds or canals, are commonly believed to solve urban heat problems but recent research shows that the cooling effect of large urban water bodies on hot summer days is quite limited and can actually induce a night-time warming effect. However, shading, vaporising water …

The changing climate has an effect on the quality of life in our cities: heavier rainfall (resulting in floodings), longer periods of drought, reduced air and water quality and increasing temperatures in cities (heat stress). Awareness about these changes among various stakeholders is of great importance. …

Urban water bodies like ponds or canals are commonly assumed to provide effective cooling in hot periods. Some of the evidence that feeds this assertion is based on remote sensing observations at relatively large scales. Such observations generally reveal reduced surface temperatures of water bodies …

‘s Zomers zullen steeds vaker langere periodes van hitte gaan optreden. Wat heeft dit voor effect op de lokale watertemperatuur? En heeft het zin om waterpartijen te verdiepen? Met de klimaatverandering zullen de watertemperaturen toenemen. Lokaal verdiepen heeft weinig effect op de gemiddelde watertemperatuur. …

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 …
