Energy Renovation for Zero-Carbon Buildings in Cameroon: Methodology

Abstract

This article presents an effective methodology for renovating buildings in Cameroon towards achieving net-zero carbon emissions. It emphasises two critical conformity assessment approaches: prescriptive and performance-based. The article specifies some building envelope and systems requirements and develops the EDGE energy software’s methodology. That software is accessible and facilitates evaluation of energy saving measures during the renovation process. The core of the article focuses on a multi-step building energy and resource optimisation methodology. This comprehensive process commences with a site survey to gather data on location, environment and climate. Following this, detailed building inventories on structure, functionality and aesthetic levels are developed to establish a baseline understanding of energy consumption patterns and potential inefficiencies. With this information in hand, the methodology guides through renovation planning, encompassing the identification of optimal upgrade strategies and the creation of a prioritized renovation roadmap. The design phase incorporates modelling techniques to visualise the project and evaluate the predicted energy performance of the renovated building. Additionally, the methodology incorporates quantity surveying to estimate the resources required for the renovation, providing with an understanding of the project’s cost implications. Finally, the methodology emphasises the importance of rigorous impact assessments to quantify the environmental, economic, social and cultural benefits achieved through the renovation. By implementing this comprehensive methodology, stakeholders and building owners in Cameroon can gain a roadmap for transforming their existing buildings into sustainable spaces. This paves the way for a more sustainable built environment in Cameroon, contributing to the country’s transition towards a net-zero carbon future.
