ABSTRACT

PURPOSE

This paper explores the role of Public-Private Partnerships (PPPs) in promoting green retrofitting of existing buildings in South Africa, with a focus on the Gauteng province. It aims to highlight the untapped potential of PPPs in supporting the country’s transition to a low-carbon built environment, especially in this era of rising energy demands and environmental concerns.

DESIGN / METHODOLOGY / APPROACH

The study uses a quantitative research approach. Data were collected through structured questionnaires distributed to key stakeholders in the Gauteng area, including government officials, private investors, building managers, and construction professionals. The survey measured their perceptions, experiences, and readiness to engage in green retrofit projects through PPP models.

FINDINGS

Results show that stakeholders recognize the benefits of PPPs in driving sustainable building upgrades, particularly in terms of funding, innovation, and technical support. However, the study also reveals gaps in awareness, policy support, and institutional capacity that limit the full use of PPPs for retrofitting. Many respondents agree that with better incentives and clearer frameworks, PPPs could significantly accelerate green retrofit projects across the province.

RESEARCH LIMITATIONS / IMPLICATIONS

The study is limited to the Gauteng province and relies on self-reported data, which may not fully capture national trends or long-term impacts. Further research could expand to other provinces.

PRACTICAL IMPLICATIONS

The findings can inform policymakers, municipalities, and private investors on how to design better PPP frameworks for green retrofitting in urban areas.

WHAT IS THE ORIGINAL / VALUE

This paper provides fresh insights into the underexplored link between PPPs and green retrofitting in South Africa.
