    Comparing occupant satisfaction in Green versus Conventional Residential Real Estate in South Africa
    (Proceedings of the AfRES 2024 Conference, 2024-09) Masotya, Adam; Simbanegavi, Prisca; Weaich, Malcolm; Adewunmi, Yewande; Ndlovu, Pride; Gethe, Faranani
    This study compares occupant satisfaction in green versus conventional residential real estate in South Africa. It investigates the benefits and satisfaction levels related to green developments, particularly in terms of energy savings and socio-economic Impacts. The research aimed to determine if there is a significant difference in occupant satisfaction between green and conventional residential developments. A quantitative approach was employed, utilizing stratified random sampling to survey 160 occupants from two developments: Crossberry Central (green) and Little Manhattan (conventional). Data was analysed using the Mann-Whitney U and Wilcoxon W tests due to non- normal data distribution. The findings indicate that occupants of green developments report significantly higher satisfaction levels. Key areas of satisfaction include air quality, utility savings, and environmental benefits. Green developments demonstrate higher levels of satisfaction regarding reduced utility bills, improved indoor air quality, and contributions to environmental conservation. The study concludes that green residential developments significantly enhance occupant satisfaction compared to conventional housing. This suggests a socio-cultural shift towards valuing sustainable living environments, emphasising the importance of promoting green building practices to improve both environmental and occupant well-being.

    Investing in the Future: A Comparative Analysis of Green Technology Investments and Youth Unemployment in the US and South Africa
    (Common Ground, 2024-05-14) Weaich, Malcolm; Weaich, Sherwyn; Simbanegavi, Prisca; Ndlovu, Pride
    This study explores the nuanced relationship between sustainable investments, particularly from entities such as the United States (US), and their impact on unemployment trends in South Africa, contributing to discussions on sustainable development goals (SDGs). Utilizing a quantitative approach with data from sources such as the World Bank and Statistics SA, this study employs statistical and econometric methods to assess the socioeconomic consequences of international sustainability funding. The findings indicate a significant link between US sustainable investments and youth unemployment in South Africa, challenging and reinforcing existing research. It depicts that while foreign investments in green initiatives are crucial, they may inadvertently affect local employment negatively. This study recommends policy adjustments in both US and South African legislation to align foreign investments with SDGs, aiming to mitigate youth unemployment. This study underscores the importance of understanding the implications of international funding conditions on local economies, offering insights for policymakers and scholars to develop strategies that leverage sustainable investments for economic growth and employment opportunities. This study provides a fresh perspective on the dynamics between international investments and local unemployment, offering valuable insights for economic planning and policy formulation in South Africa and across other African nations.

    The 'Massive, Little' Houses: 'Prefabs', A Solution for Informal Settlement Housing Crisis in South Africa! A Scoping Review
    (Construction Business and Project Management Group, University of Cape Town, 2024-08-27) Simbanegavi, Prisca; Weaich, Malcolm; Adewunmi, Yewande; Ndlovu, Pride; Gethe, Faranani
    Unlike most continents, Africa still grapples with urban informality, where housing shortages affect most people living in substandard conditions. Prefabricated housing (PH) presents an alternative option that provides a quicker and cheaper housing supply, although it currently lags behind demand. This paper examines whether 1) informal settlements can be upgraded using prefabricated/modular houses, 2) these housing types are desirable to occupants, and 3) alternative houses should receive as much emphasis and policy support as possible, particularly considering the challenges experienced during the COVID-19 pandemic. Based on a comprehensive literature survey utilising a scoping review methodology, the paper indicates that stakeholders such as developers, financiers, and occupants of prefabricated housing increasingly embrace PH despite its challenges. The literature unanimously agrees that substantial efforts are required to catalyse more investment in PH regarding further research, education, supply chain improvements, and enhanced communication and collaboration among industry stakeholders. Additionally, numerous research gaps need addressing, including in-depth examinations of PH's contextual feasibility and performance across different geographical areas. The paper recommends that South African governments adopt PH as an alternative housing solution, as it is faster and cheaper, thereby aiding in achieving the 2030 Sustainable Development Goal 11.

    Willingness of End Users in Embracing Sustainable Housing in South Africa
    (University of the Witwatersrand, 2023-10) Weaich, Malcolm; Simbanegavi, Prisca; Ndlovu, Pride; Rikhotso, Thulisiwe; Ntshangase, Noxolo
    Purpose: This study examines South African end-users' willingness to adopt sustainable housing, identifying preferred materials and investment levels. It aims to inform sustainable material adoption to reduce construction-sector carbon emissions. Approach: A quantitative survey collected data on attitudes, knowledge, and willingness to pay for sustainable housing. SPSS was used for data analysis, focusing on socio-economic status, willingness to adopt sustainable homes, and cost comparisons with traditional materials. Findings: Middle and high-income earners are more willing to adopt sustainable housing, despite higher costs. South Africans prefer materials that reduce energy grid dependence and are willing to pay for its full conversion. Regression analysis identified preferred sustainable options across income levels. Based on its findings, the study challenges the notion that affordability is the sole driver for low adoption levels of sustainable living in South Africa, emphasising individual values and the need for inclusivity in sustainable housing. Limitations: The study's small sample size of 88 participants limits its scope. Future research should include longitudinal studies and deeper exploration of sustainable housing stakeholders and explore interventions, through end-user perceptions at a more in-depth level to form a theory of adoption pertaining to sustainable housing practices phenomena. Practical implications: The study establishes a market demand for sustainable housing in South Africa, advocating for government and industry collaboration to boost awareness and adoption. Value of paper: The paper informs policy, guides industry sustainable housing practices, and aids in the development of targeted strategies to promote sustainable housing and reduce its carbon footprint. Keywords: Construction industry, End-user willingness, Green building certification, Sustainable development, Sustainable housing.
