Building in hot or tropical climates remains a challenge. This can be technical when it comes to ventilation, but also demographic since two thirds of the cities are located in this type of region. In this dossier, you will learn more about bioclimatism, biomimicry, or to discover the difficult gestation of local industries, often based on ancestral knowledge.
Building in a warm climate also means adapting to standards or market dynamics from temperate countries. The social aspect has therefore not been forgotten. The problem of air conditioning is closely linked to it, as is the use of raw earth or biosourced materials.
And to go even further, join the online community on Sustainable Construction in warm and tropical climates .

A special dossier produced in collaboration with Nomadéis, and with the support of the French Environment & Energy Management Agency
Under the concept of "hot climates", this dossier will address sustainable construction in tropical regions, but also in desertic regions. An insight into the concept of "hot climates" that motivated the choice of this geographical area.
Nicolas Dutreix, Associate director at Nomadéis
What is the definition of a tropical climate? What is a desert climate? Elements of definition on the geographical areas covered in this dossier.
Brahmanand Mohanty, Asian Institute of Technology, and special advisor for the French Environment & Energy Management Agency
The bioclimatic approach seems well suited for construction in a warm climate. What are the rules and principles of bioclimatism? What importance do local sectors have in sustainable construction in hot climates?
Alain Bornarel, engineer specialized in urban planning and civil engineering at the École centrale de Paris, founder of the TRIBU design office
Beyond natural ventilation and the envelope, the greening of the building is an essential element of bioclimatic design. Inventory of existing standards, regulations, and solutions.
Antoine Perrau architect specialized in bioclimatism and environmental urban planning in tropical environments
Inspired by Nature for human production, this is the essence of biomimicry. Used by scientific research, this know-how is also highly appreciated in architecture. To what extent does Nature have efficient models to teach us to limit our energy expenditure?
Nicolas Vernoux-Thélot architect and founder of the firm In Situ Architecture and designer of the church of NianingDiscover
Enhancing the value of local supply chains for biosourced materials is a major challenge for sustainable construction, particularly in hot climates. However, despite the abundance of materials, they are struggling to form.
Bernard Boyeux, Director of C&B Constructions et Bioressources.
A synthesis of the "BIOREV Tropics" study, led by Nomadéis, BioBuild Concept and the Urban Ecology Laboratory. This document defines the particularities of insularity and the difficult problem of local sectors, particularly in the French tropics.
Jérôme VUILLEMIN, researcher at the Tropical Building Innovation and Research Centre (CIRBAT).
Adapting construction techniques and the choice of materials is necessary to improve the comfort and energy efficiency of buildings in tropical or Sahelian climates. The typha, a wild plant, could contribute to answering this challenge of sustainable construction.
Ernest Dione, national project coordinator TyCCAO
In Senegal, architects and contractors are taking inspiration from old-fashioned raw earth houses and reviving local know-how to build sustainably. The coming years will probably be important for this ancestral and accessible building technique to continue. A look back at these challenges with Worofila Architecture.

From the Overseas Departments the use of expensive and polluting air conditioning systems is very significant. Committed to a sustainable development approach, France must implement strategies to limit energy consumption. Energy news in the West Indies
Pricillia Privat, Head of the Agency of the design office H3C-CARAïBES in Guadeloupe and Loic Nohilé - Project Manager in the Martinique agency
Sustainable construction in a hot climate is not only a technical challenge. It also requires taking into account a particular social context. The example of French Guiana.

The urban context of large Brazilian villas and the consequences of climate change. How can we meet this challenge in the major cities of developing countries?
Sergio Myssior, director and partner of Myr Projetos Sustentáveis.
In response to the housing problem in Africa, the Association la Voûte Nubienne (AVN) has been promoting the technical concept Voûte Nubienne (VN) in Sudano-Sahelian Africa for almost 20 years, a complete, adapted and sustainable constructive solution.

The cities of the Sahara are located in one of the regions most vulnerable to the effects of climate change, in particular due to the fragility of the economy and infrastructure. How can the urban environment of Saharan cities be developed to make it more resilient?

Building sustainably in Peru faces a first obstacle: the country's lack of institutionalization. It is therefore difficult to disseminate and perpetuate good practices. Beyond this observation, this article provides some initial solutions.

The impacts of climate change on populations living overseas and the need to relocate them. How to anticipate these constraints?
Emmanuelle Durandau, Deputy Permanent Secretary at PUCA
By showing that a given place in the world could experience a similar climate in the future to another place in very different latitudes, the climate analogues method makes it possible to imagine the impact of rising average temperatures.

L’ADEME s’engage particulièrement sur le sujet de la construction durable sous climats chauds, s’appuyant notamment sur l’expérience des territoires d’outre-mer français qui ont développé des approches et outils spécifiques aux climats tropicaux. C'est dans ce cadre que l'ADEME apporte son soutien financier aux Green Solutions Awards et à ce dossier, qui concourt aux échanges et réflexions sur la thématique. En revanche, l'ADEME n'a pas apporté sa validation technique à ce dossier, les contenus étant publiés sous la seule responsabilité de leurs auteurs. Lire +
