Abstract

Buildings play a central role in a decarbonised & zero-emissions future. Projections indicate a doubling of population by 2050 in Africa, which implicates expanding already insufficient the building stock. New buildings should be designed according to concepts that will make them robustly comfortable against climatic changes and with low energy needs. However, globalisation trends in building design resulted in inadequate solutions for warm climate regions, performing poorly energy & comfort wise.

Analysing and documenting the best sustainable solutions for warm climates is crucial to popularise these concepts and support communities, local construction & manufacturing. The solutions involve a bioclimatic approach, passive cooling techniques, and local low embedded energy construction materials. These concepts and designs already exist in Africa, needing to be identified, documented, standardised and adapted to new conditions & technical possibilities. A recent publication from UN in COP26 presented a series of cases studies documenting worldwide proven options to help cool cities. Strikingly, there were no examples from African cities listed, even though several techniques and designs are flourishing in the region. ABC 21 project aims to fill this gap & promote exchange of best practices between Africa & Europe.

The goal is to present the project’s recent findings regarding operative case studies in both regions that follow the bioclimatic and energy efficiency principles for achieving comfort in warm climates. Besides, we will also address how do local geo-bio-based constructions materials and techniques contribute to energy-efficient buildings. How policies and regulations can support and facilitate the dissemination of these techniques and the capacity building in the construction sector, public calls & regulation? The exchange between Africa & EU will contribute significantly to the increased use of adequate locally adapted and climate-resilient buildings.
