Contribution

It introduces a novel approach coupling mobile and fixed measurements to quantify microclimatic impacts of schoolyard renovations.

Findings

Heat stress mapping identifies critical microclimatic zones.

Methodology effectively diagnoses heat stress levels.

Supports urban planning for climate resilience.

Abstract

Climate change will result in more frequent, more intense and longer-lasting heat waves by 2050. As part of its Climate Plan and its resilience strategy, the City of Paris is deploying, through its Oasis program, a network of urban cool islands to mitigate the urban heat island phenomena: schoolyards are renovated in order to reduce the heat stress of users. We establish a methodology aiming to quantify the microclimatic impact of the transformation. Mobile measurements are carried out within a case courtyard under hot conditions and coupled with fixed weather station data to evaluate heat stress using UTCI. The heat stress mapping thus obtained allows a first microclimatic diagnosis of the schoolyard.
