Étienne Chantoiseau

Teacher researcher in Energy and coupled mass-energy exchange

Department of Physical Environment, Landscape Architecture and Territorial Development

Teaching unit: Physics of transfers and bioclimatology
Research unit: Physical Environment of the Horticultural Plant

Academic background

After a Food Engineering MSc at ENSIA (now AgroParisTech), I made a Ph.D. in chemical and environmental engineering at École des mines d’Albi on coupled mass and energy transfers in deformable porous media. After a post-doctoral position at AgroParisTech studying dairy thermal treatment, I obtained my current position of Associate Professor in 2011.

Teaching

My classes are mostly about transport phenomena and their application to horticulture and landscape architecture, from meteorology (L1) to irrigation scheduling (L3). The scientific knowledge and skills exposed are then re-used and improved during the horticultural science and engineering MSc.

Undergraduate courses

B1: Meteorology and Bioclimatology
B3: Hydrology and mechanic piratical work
B3: Thermic, energetic and Bioclimatology (L3I et L3A)
B3 : Integrated Project of Applied Physic (L3I et L3A)

Graduate courses

M1: Soilless and undercover crop
M1: Landscape engineering - Photometry and lighting
M2: Abiotic component of the urban environment (M2 GDV)

Since fall 2017, I have also been co-manager of the engineering graduate specialisation I2PH (Ingénierie des productions et des produits de l’horticulture – Engineering of the horticultural processes and products). This graduate program aims at training engineers able to manage horticultural systems (fruit, vegetable and ornamental crops) by innovation, from the production to the marketing. More particularly, I am respobible for a large student project about the “sustainability of greenhouse systems”.

Research topics

My research interest is about the coupled mass-energy transfers in the context of horticultural production. Currently, two main problematics are investigated: the efficient management of production greenhouse climates, and the studies and modelling of the energy and water transfers in the substrate-plant-atmosphere continuum.
The models developed for the horticultural applications are currently adapted to urban applications. The aim there is to reduced water consumption while guaranteeing the ecosystem services of the urban plants – particularly the evaporative cooling to mitigate the urban heat island effect.

Research programmes

Current programmes

•  Nature 4 Cities (2016-20): funded by the European Commission (H2020). Nature4Cities aims at developing complementary and interactive modules to engage urban stakeholders in a collective-learning process about renaturing cities, develop and circulate an extensive knowledge base on Natural Based Solution (NBS), new business, financial and governance models for NBS projects, as well as providing tools for the impacts assessment, valorization and follow-up of NBS projects. Our aims will be to provide performance assessment of NBS regarding a range of urban challenges by providing definitions of a multi-scalar and cross-thematic set of urban performance indicators.

•  Urbinat (2013-2018): focuses on the regeneration and integration of deprived social housing urban developments through an innovative and inclusive catalogue of Nature-Based Solutions (NBS), ensuring sustainability and mobilizing driving forces for social cohesion. Interventions focus on the public space to co-create with citizens new urban, social and nature-based relations within and between different neighborhoods. Taking the full physical, mental and social well-being of citizens as its main goal, URBiNAT aims to co-plan a healthy corridor as an innovative and flexible NBS, which itself integrates a large number of micro NBS emerging from community-driven design processes.

Recently finished programmes

•  Plantinov’ser (2009-13): Funded by ADEME and Région Pays de la Loire. This project aimed to limit the greenhouse crop systems energy consumption by providing new cultivars and new climatic strategies. The research unit shown the economic and technical interest of dehumidification heat pump. Experimental validation conduced on ornamental crops prove the efficiency of our innovative control strategy.

•  Physi’Ho (2012-16): Funded by Région Pays de la Loire and producers. The project aims to understand the interactions between climate, pathogens and hydrangea physiology, and their influence on the plants storage.

•  Conser (2014-16): Funded by Région Pays de la Loire. This project aims to improve the understanding of the cucumber plants responses to greenhouse climate. The project made a physiologic reference of the cucumber photosynthetic efficiency according to climatic conditions in order to improve the energetic efficiency of the climate strategies.

•  Projet OBAUC (2016-17): funded by Régions Pays de la Loire. The aim of the project is to characterize plant-environment interrelations, to understand and predict plant development. The specific goals are to analyze the combined effects of soil compaction, water supply restriction and shading on plant transpiration, plant biomass as well as aerial and root architecture.
