Experimental sites – summer 2021

This summer, we went to Paris La Défense to investigate three spatio-climatic devices in collaboration with Paris La Défense, Efficacity, Véolia, Université Gustave Eiffel and Engie. Efficacity and Paris La Défense have launched two experiments to refresh public spaces during this summer, also presented as “Oasis of freshness” (additional information: or https: // These include a “refreshing platform” from Seureca / Veolia and a “fresh island – skycooling” from Engie Solutions, placed on the forecourt near the Grande Arche of La Défense (Figure 1, top). In addition, we wanted to add to this campaign a third site, consisting of a landscaped sequence of gardens on slabs, called “Sequence Agam”. It was designed by Atelier Foïs and is located between the fontaine Agam Place and the Basse Place (Figure 1, bottom).

Mobile microclimate and ethnographic observations were carried out between July 18th and 22nd, 2021 between 11:00 a.m. and 6:30 p.m. for 5 consecutive days, juggling between the three sites. These observations complete the static measurements carried out by permanent stations during the test period. The stations are directly set up on the refreshing platform and the fresh island as well as on the square in between.
