Urban heat island mitigation : a field evaluation of a pervious pavement combined with pavement watering

Résumé

In the context of global warming, cities need to be prepared to limitate thermals stress in city, especially during heat wave, when the it’s become to be a health issue. This study is focused on evaluating the cooling effects of a pervious, ochre pavement combined with pavement-watering in response to the urban heat island effect and extreme heat events to offering permanent cooling effect and stronger effect with water mitigation, althougth punctual. A micro-climatic study was conducted following a Before After Control Impact (BACI) design to evaluate the effect of the new pavement and watering on pedestrian heat stress during typical heat-wave conditions. The surface temperature of the 100m² test site was also monitored. Since the pervious pavement have a low albedo, we see no significant effect compared to standard pavement although with the use of water we are able to see a cooling effect of -15°C on the surface imputing a -1°C refreshing effect on air temperature at 1.6m height.
