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.

#5 Biomimetism: a solution for building in hot climates?

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?

#6 Construction of local building materials sectors: a social as well as an economic challenge

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.

#8 The use of typha in Senegal, interview with Ernest Dione

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.

#9 Construction with raw soil in Senegal

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.

Dossier soutenu par

Construire durable sous climats chauds
 
 

 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 +
