An Analysis of Barriers to the Implementation of Energy-Efficient Technologies in Residential Buildings: A Quantitative Approach

Building owners and occupants encounter challenges in implementing energy-efficient technologies arising from high upfront costs, limited awareness, and inconsistent policy enforcement. This study aims to investigate the barriers that prevent the adoption of energy-efficient technologies in residential buildings. A case study research design was used to collect quantitative data using a survey questionnaire in the Brandwag area of the Mangaung Metropolitan Municipality in South Africa. The findings reflect building occupants’ perceptions regarding the effectiveness of various barriers encountered during the implementation of energy-efficient technologies in buildings. Notably, the highest-ranked barrier was the limited availability of financial support, which received a mean score of 4.19, while the lowest-ranked barrier was the shortage of qualified or skilled professionals, with a mean score of 3.78. An integrated strategy that simultaneously addresses financial processes, technical capacity building, and standardized regulations is essential for the successful adoption of energy-efficient technologies in residential buildings. However, a limitation of the study is its reliance on a survey-based research methodology for data collection. Although a quantitative approach was prioritized, the low response rate of the survey limits the generalizability of the findings. Future research should address this limitation by employing a mixed-methods research design for comparable evaluations focusing on South Africa, not just a province.
