Evaluation of sustainable building technologies adoption in housing construction across socio-economic contexts in Cape Town, South Africa

This research explores the adoption patterns and the key factors affecting the adoption of innovative sustainable building materials in housing construction across socio-economic contexts in Cape Town, South Africa. A mixed-methods approach was used in collecting data using semi-structured interviews and the survey questionnaires randomly distributed to Cape Town residents and purposively selected professionals working in the housing construction projects. The data collected was analysed using descriptive, thematic, and inferential statistical technics. The study found that most respondents from both classes were aware of sustainable building technology and materials and perceived that environmentally friendly building materials lessen the impact of construction on the environment. The majority of low-class respondents lack access to resources such as government assistance and financial resources compared to middle- and high-class respondents. Both groups utilize recycled materials more often than not. No significant difference was found in the main variables influencing respondents' choices regarding the use of sustainable building materials across the middle-high-class and lower-class groups. In South Africa, the adoption of sustainable building practices is impeded by socio-economic constraints, technological limitations, economic barriers, and insufficient awareness. This study advances knowledge of the how economic circumstances affect at different levels the use of sustainable building materials and technology in housing construction. The study recommends that governments and financial institutions creates initiatives in the form of trainings and financial incentives to equip stakeholders with the necessary information to improve the likelihood of adopting sustainable practices.
