L’optimisation Energétique et des Ressources des Bâtiments Hôteliers au Cameroun dans l’Optique Zero Carbone

Abstract

Cameroon, like other countries around the world, is committed to the fight against climate change. The building sector, particularly the hotel industry, is a major contributor to greenhouse gas emissions. This article examines strategies for optimising energy and resources in hotel buildings in Cameroon, with a view to achieving the zero-carbon objective. It concludes that the current situation of the hotel sector in Cameroon presents a potential for reducing greenhouse gas emissions in order to achieve the country's ambitious environmental objectives at global, continental and national levels such as the submission of the Nationally Determined Contribution under the Paris Agreement in 2015, the Agenda 2063 adopted in 2013 by the African Union and the National Development Strategy 2020-2030. Successful strategies for renovating hotel buildings adapted to Cameroon have been developed. These involve improving the insulation of the building envelope, the efficiency of systems and the use of renewable energy sources. Finally, the authors highlight the importance of the prescriptive approach for assessing and the energy performance approach for optimising building performance, using the highly accessible EDGE energy simulation software. To achieve the EDGE Zero Carbon level, it is essential to demonstrate minimum savings of 40% of energy, 20% of water and 20% of grey energy in materials, and 100% of energy-related emissions neutralised either by renewable energies or by carbon offsets.
