- Urban design
The project Aéro-Seine deals with the temperature increase in urban space. Dense cities, with many impervious surfaces, and non vegetated, will be more and more faced with the heat island effect.
In Paris, for instance, the daily middle temperatures are already around 2 to 3°C up to the rest of the region? This can reach up 10°C in the summer.
Therefore the City of Paris has a specificity that may be an effective reponse to that issue : the non-drinkable water network. By the 19th century, Paris had set up a network for non-drinkable water to be used for watering public gardens and cleaning the streets. This system draws water from the main river, Seine. The water then goes to three water plants where it is just filtered no treated chemically. What is interesting with this water system is that it enables to provide a cheaper and less energy consuming than drinkable water.
Aéro-Seine is a cooling point for public spaces that cool the ambient air thanks to evaporation of water thanks to a porous material. In period of strong heat or heatwaves, municipal cleaning agents may open the valve of this device. Once open, the water rises in a small tank and then passes through a grid. The water then spreads on a porous surface and evaporates, providing cooling ambient air.
The device has been complemented by floor markings designed with children living in the neighbourhood.
A team of researchers (Water department of the City of Paris) have done some temperature measurements during two summers.

A multidisciplinary creative agency founded by Isabelle Daëron in 2018, Studio Idaë arose from a reflection on the use of natural flows — water, air, light — in public space.
The Studio has, ever since, developed an approach based on research and education, focusing on the urban, environmental and societal challenges of the ecological transition.
Driven by a poetical & committed team of designers, Studio Idaë applies its refined, assertive graphic signature to projects of various scales. From urban devices to mediation objects and supports, or scenography, the agency’s protean contributions always strive at others — their needs, their desires, and their evolution.
The agency operates within a network of local companies and collaborates with dedicated craftspeople to adapt to the specific characteristics of each territory. Together, they work towards the most appropriate and relevant response — between narration and mediation.

Designer and design researcher, Isabelle Daëron graduated from the École Supérieure d’Art et de Design in Reims in 2005 and the École Nationale Supérieure de Création Industrielle in Paris in 2009. She founded Studio Idaë based on her reflections on the use of natural flows—water, air, light—in public spaces. At the heart of the agency’s work, her practice of drawing and narrative opens up the imagination and a sensitive understanding of environments and their resources.
Pauline Avrillon, a graduate of the École Boulle (DSAA product design and DMA carpentry), has been working with Isabelle Daëron since 2016, even before the studio was founded. As a senior project manager, Pauline has a particular interest in materials and manufacturing processes that contribute to resilient and innovative public spaces. She is involved in urban development projects, as well as projects combining mediation and territory.
A graduate of Ensci-Les Ateliers, Nina Capron joined the team in 2024. Within the studio, she is developing expertise in spatial design projects. She pays particular attention to the narrative and educational challenges inherent in the creation of scenography and installations.
Julie Deloraine, a graduate designer from Esad Saint-Etienne, joined the studio in 2025. By collaborating on set design projects, Julie meticulously develops the graphic and visual aspects of our creations, as a means of making them accessible to all.
Eléna Hervé Caro has been Studio Idaë’s office manager since 2023. A trained designer (graduate of the Design Academy Eindhoven and École Boulle), she oversees the administrative and logistical aspects of the studio’s activities. Convinced of the impact of teamwork and the power of good planning, she contributes to upholding the values of the studio and the entire ecosystem.
