In order to adapt to climate change, cities are studying various urban cooling techniques to improvepedestrian thermal comfort of users during heatwaves including urban greening and cool materials 1,2. Ontechnique being considered by the City of Paris is cool pavements 3 . To this aim, an experimental test sitehas been constructed and instrumented to study the thermal and climatic behavior of candidate sidewalkstructures.The experimental demonstrator is located in Bonneuil-sur-Marne near Paris, France. This experimentaldevice consists of 16 samples of various sidewalk structures 4. Each sample is approximately 4x4m acrossby 25 cm deep and is composed of several layers following real-world conditions. The samples areinstrumented with temperature and heat flow sensors at several depths, with the data recorded every 5minutes. Additional weather measurements are also conducted onsite to monitor air temperature andhumidity, global horizontal short- and longwave irradiance as well as wind speed and direction.This communication is focused on data collected during the summers of 2021 and 2022, specificallytemperatures and heat fluxes and the derived surface heat budget of each sample. These data from eachstrcture will be analyzed with respect to their contribution to the degradation of pedestrian thermal comfortas well as to the urban heat island effect in order to inform the city services in their selection of suitedsidewalk materials.Additional testing inside a climate chamber will supplement the demonstrator test site with complementarymeasurements performed in the laboratory.
