Méthodologie de Rénovation Energétique dans l’Optique Zero Carbone des Bâtiments au Cameroun

Abstract

Reducing greenhouse gas emissions in the building sector is a major challenge, as this sector accounts for 38% of total global CO2 emissions. The aim of this article is to propose an effective methodology for the energy renovation of Cameroonian buildings that will enable carbon neutrality to be achieved. The methodology chosen to achieve this objective is based on prescriptive and performance-based approaches. After surveying the site, an inventory of fixtures will be drawn up and compared with the energy efficiency requirements set out in Ivorian interministerial decree no. 134/MPEER/MCLU of 18 November 2020. Emphasis is placed on how to carry out a complete assessment of the building in order to identify weak points and levers for improvement. The performance-based approach then takes over, and the energy simulation software chosen is EDGE for its accessibility. The methodology of the EDGE application is presented. Finally, all that remains is to plan, design and model the renovation project. This article is therefore presented as a guide to building renovation in Cameroon.
