An analysis of challenges influencing the adoption of green retrofitting in existing buildings in South Africa

Purpose As the world grapples with the challenges of climate change, the necessity to improve the energy efficiency and sustainability of existing building stock has become increasingly urgent. This has made green retrofitting an important strategy for existing buildings. Despite its potential environmental and socioeconomic benefits, the adoption of green retrofitting practices remains limited, particularly in developing countries. This study investigates the key challenges hindering the widespread implementation of green retrofitting in South Africa's existing building stock. Africa's existing building stock. Design/methodology/approach The quantitative research approach was adopted in the study. Through a scoping literature review complemented by a survey, primary data were collected by administering questionnaires to randomly selected professionals in the South African construction industry. Thereafter, descriptive and inferential statistics were computed from the analysis of the data. Findings The research identifies critical challenges, including a lack of awareness regarding the benefits of green retrofit project implementation by clients, a lack of incentives to promote the adoption of green retrofitting of existing buildings, extra costs for transportation of imported materials and a lack of training regarding green retrofitting initiatives among built environment professionals (BEPs). Furthermore, the non-parametric test revealed that there is no significant difference regarding the challenges of green retrofitting of existing buildings across the different built environment professions. Originality/value The findings highlight the need for targeted capacity building initiatives, increased public and private sector collaboration, and an integrated policy framework to facilitate the transition to sustainable building. The study provides invaluable insights for industry stakeholders aiming to promote green retrofitting.
