In the Sahel, how to deal with the "triple bomb climate" ?

As many countries of the sahelian zone, Senegal is highly impacted by climate change. Original mainly anthropogenic, this phenomenon is exacerbated by the use of construction materials that are unsuitable, often sources of heat. The warming of cities generates a ” triple bomb climate “ due to the massive use of air-conditioning and ventilation. In other words, the use of these solutions imply an overconsumption of electricity which leads to a “surémission” of CO2 in the atmosphere, creating, thus, the effect of urban heat island.

In Senegal, the urbanization is dominated by its capital, Dakar, which concentrates 25% of the country’s population, 55% of the national GDP, 80% of enterprises and jobs, modern, and 87% of local taxation. In Dakar, the urban question is today marked by socio-climatic habitat improvement and because :

  • the housing crisis that affects mainly the low-income households,
  • in The absence of insulation in buildings, real strainers thermal.

"Cool of the city" : a project at the initiative of Cool Roof

Faced with this situation overwhelming, Cool Roof , launched in April 2020, the project ” the Cool of the city “. This project’s main objective is to introduce the cool roofing in Senegal, so as to raise awareness among the different stakeholders to the issues of adaptation of buildings, neighbourhoods and cities. In this framework, Cool Roof France was allied with various local stakeholders, including theAgency’s Management of the Built Heritage of the State (AGPBE), the local company MAOR Technologies and consulting firm in the energy efficiency EMASOL.

Together, we have defined a list of 4 demonstration sites :

  • The high School J. F. Kennedy,
  • The high School Delafosse,
  • The National Blood Transfusion Centre,
  • The health Centre Hann Maristes.

 

once this step is completed, our Office of Study Materials was carried out tests in order to adjust our coating CoolRoof to the conditions in senegal.

To measure its effectiveness, our Office of Thermal Studies is collaborating with the cabinet senegalese EMASOL, specializing in energy efficiency. Thanks to a partnership with theEcole Polytechnique de Thiès (FTE), connected sensors have been manufactured by a team of student engineers. They have also developed an interface to users, which lets you see live data before and after application. Through this approach, Cool Roof France wants to contribute to the development of local skills, and allow engineers to become involved in the implementation of a concrete project and innovative.

At the present time, Cool Roof and MAOR Technologies work in conjunction with the organization of the building site. On the occasion of a field mission, Cool Roof will form a team of 24 applicators local to the application of the solution. This team will be responsible, for the following, from the cleaning of roofs and the installation of the CoolRoof on different sites.
