With the impact of climate change becoming more pronounced and the frequency of extreme heat events increasing, cities must find ways to mitigate prolonged periods of soaring summer temperatures. Heatwaves and the Urban Heat Island effect, caused by the mass of hard surfaces of concrete, brick and asphalt in cities, place the elderly and those with chronic conditions most at risk. This webinar looks at the possible solutions from incorporating more green infrastructure and other passive options to active technologies, and how a multi-disciplinary approach by built environment professionals can make our cities cooler.
