Konseguela won the Low Carbon Award of the 2019 Green Solutions Awards at the Mali level + a mention for the international Low Carbon Award.
The Electrified Activity Zone (EAZ) is an innovative project developed by the Renewable Energy, Environment and Solidarities Group (GERES) to meet the energy needs of Very Small Enterprises (VSE) in rural Mali. In Konséguéla, this first EAZ brings to the inhabitants of the commune and surrounding villages new products and services that have been expensive or unavailable. The infrastructure allows to host up to 15 craft and service activities (modern bakery, carpentry workshop, oil mill, multi-service computer center, cold /freezing service, soap factory, nutritional flour manufacturing unit, community radio ...) and to welcome customers to the site. This initiative contributes to the economic and social development and stability of the rural territories of Mali; the model is currently reproduced in the regions of Sikasso, Ségou and Kayes ...
This project may be qualified as sustainable for the following reasons:
-The buildings are built according to the principles of the Nubian Vault Technical Concept promoted by the Nubian Vault Association (AVN) in Sahelian Africa for about twenty years. Raw earth and local stone are the materials used to make all the structures: underpainting structures in cyclopean concrete / masonry raised structures with adobe. Only certain outdoor spaces between buildings are embellished with light IPE + steel box covers, allowing to generate shaded and ventilated useful spaces at a lower cost.
-The architecture proposed by Al-Mizan consists of an arrangement of small simple buildings all designed on the basis of the same module and organized around outdoor spaces allowing a fluid circulation. The set generates many shady places at different times of the day while allowing good natural ventilation.
-Finally, the EAZ is entirely autonomous in terms of energy. An electric production center equipped with a field of 53 solar panels with a power of 12.5 KW / C provided the basic needs and can be relayed by a 20 KVA auxiliary generator powered by the Jatropha pure vegetable oil, agrofuel farmer produced locally since 2008. The supply of energy 100% renewable is provided 24/7 to companies of the EAZ.

Owner approach of sustainability
Create a 100% renewable energy business zone that provides continuous electricity to very small local businesses. Use a sustainable constructive technique: the Nubian Vault Technical Concept, and contribute to its diffusion.
If you had to do it again?
The power generation system has been overdimensioned.

Local bricklighters / artisanal production mostly informal

The adobe is a mud brick molded and dried in the sun. The basic material is the building earth, whose main characteristics are: non-organic earth; fairly high clay content (25/30%) and good cohesion; worked in the plastic state (water content +/- 30%).
The Nubian Vault Technical Concept uses two models of adobe:
1 / A brick size 38 x 17 x 15 cm, used for walls, foothills and some arcades
2 / A smaller brick size 25 x 15 x 5 cm, used for vaults and common arches
Brick mortar is made with an earth mortar, generally of the same nature as that used for the production of adobes.
The product has been very well accepted by all parties involved in the project. The project owner chose the VN Technical Concept based on this material; the execution company complied with the specifications and integrated VN masons and craftsmen into its teams; the users appreciated the architectural qualities of the buildings (aesthetics, comfort, functionality).
The ZAE Konséguéla is located in a rural area, at the entrance to the commune of Konséguéla. It is served by the main track that connects the town to the town of Koutiala (+/- 50 km).

Most users, from the municipality, are not motorized. Most access is on foot or by bike, to which are added punctual deliveries.
