HeatAlert expands its reach to fight against urban heat islands


Dutch cities can experience up to a 7 degrees increase in temperatures as compared to their surroundings. The negative effects of heat islands go far beyond just breaking a sweat. They not only have an impact on the environment, but also on human health and economic well-being. This is where Sobolt comes in. HeatAlert helps municipalities make decisions to mitigate the dangerous and costly effects of urban heat islands by predicting their occurrence and alerting those most as risk.


Sobolt is testing HeatAlert by interviewing a wide range of municipalities all over the Netherlands. Many cities have an overview of heat islands but no insights into specific locations or mitigation strategies. As a result,  municipalities are in the dark as the country-wide deadline for sustainability reports draws closer.


One of the best ways to reduce the heat island effect, and that which HeatAlert focuses on, is vegetation. Studies show that optimally-placed vegetation can reduce urban temperatures by 5 degrees. HeatAlert takes heat island mapping a step further by identifying critical areas, such as  hospitals and elderly care facilities, for targeted action. By communicating this interrelated data, HeatAlert delivers actionable insights and allows policy makers and community members to see where and how to mitigate heat in the most effective way.
