During the last summer periods, European cities have witnessed the spread of refreshing installations for citizens in the public space, such as cooling canopies, water mirrors, air-conditioned envelopes, etc. How can these new forms of collective cooling shape urban atmospheres? Based on this research question, the COOLSCAPES project aims to better understand the physical, social and sensory dimensions of these spaces, which we call spatio-climatic devices, in order to better determine their future applications in the adaptation of the population to climate change. Three scientific objectives lead this project: (1) characterising the relationship between spatial configuration and climate parameters in terms of atmospheres; (2) characterising the citizens' uses and perceptions; and (3) analysing the current refreshing practices and identifying emerging lines of reflection.

This post-doc contract offer falls within the starting phase of the COOLSCAPES project, which includes the implementation of the characterization method for the spatio-climatic devices (parameters and sensations), as well as the first experimentations on different sites. More concretely, the research deals with the following aspects:
- In situ climatic data acquisition for the characterisation of thermal comfort conditions: measures regarding the air temperature, radiation temperature, relative humidity, air velocity and thermal fluxes. We are experimenting on the combined use of static weather stations and mobile measuring devices (miniature weather stations and specific sensors) that are used by the researchers or by volunteers (see Potvin and Demers 2016, Camponovo et al. 2016, Tsin et al. 2016, Chokhachian et al. 2017).
- Microclimatic data pairing with position data in space via localisation techniques. To this end, we will refer to existing methods according to the conditions on each site: inertial navigation systems (Hannink et al. 2017), computer vision tracking approach (Nielsen et al. 2014) or differential GPS (Antigny et al. 2017).
- The design and test of experimentation protocols and the processing of the results aim to cross the previous data and the one collected with investigation methods on thermal sensations – for example, commented walks, semi-structured interviews, surveys on subjective perception, cognitive maps (see Masson and Aït-Sidhoum 2011, Lenzholzer et al. 2018). This section will be both about the statistic processing of several types of quantitative data (R studio) and their spatialisation and visualization with GIS tools (QGIS), while using qualitative approaches mobilising speech, sensations and measurements (for example, directory of microclimatic effects, sensory maps, videographical approaches). Similarly, a fine work on the comfort index will contribute to this discussion – for example, UTCI, modified PET, ASV or TSV perceptive scales (Parkinson et al. 2016, Potcher et al. 2018).
- The analysis of the results from the first experimentations, proposing pluridisciplinary keys to read the different data elements that were collected. This exploratory work will be subject to work seminars with the researchers of the team and outside guests.


To carry out these missions, we are hiring one post-doctoral researcher who will:
- Contribute to the elaboration of the field experimentation protocol and participate to the operational implementation during the contract duration.
- Organise collective work seminars on the method and the crossing of research data.
- Participate in the optimisation of research results via communications in international conferences and scientific articles.

The candidate is invited to propose his/her own point of view to develop the missions according to their profile and personal interests. Moreover, they will be tasked with the regular updating of the project's literature review.


This offer is directed at PhD holders with training in engineering, architecture or urban planning, who are acquainted with questions of microclimate and urban thermal comfort. Specific skills:
- Command of the physical and perceptual context of phenomena regarding urban micro-climatology and thermal comfort.
- Technical knowledge in in situ instrumentation and programming.
- Interest in working within a plurisciplinary team.
- Proficiency in oral and written English (presentations, interviews and publications).

Work Context

Professional environment: the Centre de Recherche Nantais Architectures Urbanités (CRENAU) is the Nantes team of the Ambiances, Architectures, Urbanités laboratory AAU-UMR CNRS 1563. Its facilities are located at the Graduate School of Architecture of Nantes (http://aau.archi.fr/crenau).

Project: COOLSCAPES is a research project that is funded by the Agence Nationale de la Recherche (ANR) within their 2018 generic call in the Young Researchers category. It brings together a pluridisciplinary team associated with the Ambiances, Architectures, Urbanités laboratory (UMR 1563 CNRS/ECN/ENSAG/ENSAN). It is coordinated by Ignacio REQUENA, associate professor at the Graduate School of Architecture of Nantes.

Constraints and risks

Travels in France or other European countries for field experiments (about 12 days, between May and July), interviews or meetings (1 or 2 days) are expected.

Additional Information

In accordance with the CNRS commitment to the European Human Resources Strategy for Researchers (HRS4R), the candidates must apply on the application platform of the CNRS Portail Emploi (emploi.cnrs.fr), to the exclusion of any other process.
