Multi-scale
bioclimatic design

Bioclimatic design refers to the fact of designing with the climate in order to imagine comfortable, low-carbon, sober and resilient constructions or layouts.

The division of competences in architecture and urban planning does not allow to approach the climatic and microclimatic phenomena (sunshine, wind...) in all their complexity, nor to understand their potential.

The multi-scale approach that I claim allows me to address these phenomena at different scales, from urban planning to the interior design of buildings. It mobilizes skills in urban planning, architecture and design. My method is based on a thorough climatic and microclimatic analysis and on the development of cooling and heating techniques appropriate to the climatic deposits identified during this analysis.

Microclimatic analysis
(sunlight, wind...)

The realization of microclimatic studies constitutes an important part of my activity. They concern the effects of the development on the modification of the local climate (solar masks, thermal or nycthemeral amplitude...).

This type of study makes it possible, for example, to understand why a building or an urban morphology is thermally uncomfortable under the action of a degraded microclimate, but also to develop ways to improve comfort.

The microclimatic analyses that I carry out also make it possible to estimate the climatic potential of cooling or natural heating on a local scale. A microclimatic analysis allows for example to quantify the potential of cooling by natural ventilation in urban areas.

Low-tech
cooling & heating

More and more individuals want to develop low-tech housing that is autonomous in terms of heating, cooling, water consumption and electricity production. They also want to reduce the environmental impact of their lifestyle, by using biosourced and geosourced materials and reuse.

I accompany individuals in this type of frugal approach by recommending passive heating and cooling techniques, as well as layouts that are economical in terms of energy, mineral and metallurgical resources (copper, indium, tin...). This type of project requires a global approach to design inspired by life cycle analysis (LCA).

In this perspective, I develop passive cooling techniques and I try to imagine alternatives to conventional air conditioning systems.

Thermal comfort
& UHI mitigation

The fight against the urban heat island (UHI) phenomenon and projects to improve thermal comfort on an urban scale are major issues today because of current and future climate change. The development of bioclimatic urban planning is therefore a priority.

I accompany projects oriented towards the reduction of the urban heat island in several cities (Angers, Dijon, Vitry-sur-Seine...). I work in the start-up SOLENEOS, based in Nantes and specialized in urban microclimate modeling, where I make recommendations based on their simulations.

I also develop a range of urban furniture designed to promote thermal comfort outdoors. In particular, I have developed the abrise, a prototype of furniture designed to promote natural ventilation outdoors.
