    Impact of Green Building Features and Initiatives on Individual Productivity and Organisational Performance in Office Buildings
    (University of the Witwatersrand, Johannesburg, 2023-06) Nurick, Saul David; Thatcher, Andrew
    The uptake of sustainability within the real estate sector has come to the fore in the last twenty years. More specifically this has involved the development and implementation of green certification tools within the commercial property market. There are various green building tools that are applied in the different developed markets to standardise building certification within each market. Some tools are adapted versions of another tool, for example Green Star (Australia) was used as the benchmark for the development Green Star South Africa. One of the categories within every type of green building tool is indoor environmental quality (IEQ). Building occupants tend to be more aware of their indoor environment more than any other building component that may be classified as a green building feature and initiative (GBFI). Specific GBFIs impact the following IEQ factors: ventilation, natural vs artificial light, ambient temperature, humidity levels, noise levels, and office configuration. Green building research has shown that operationally green buildings benefit both owners and tenants, which also has a positive impact on building values. Many green building advocates have stated that green buildings also result in improved individual productivity and organisational performance. There is, however, conjecture amongst academic researchers regarding the accuracy of measuring productivity of knowledge workers within an office environment. Common approaches for measuring productivity include creating a simulated office as an experimental environment and setting tasks for the participant to perform in different environmental conditions. Post occupancy evaluations (POE) and building user surveys are other instruments for gathering productivity data, however these are often in the form of self-assessment, which carries an element of bias. The purpose of this research was to develop and test a theoretical framework that connected the implementation of GBFIs, specifically enhanced IEQ, to individual productivity and organisational performance. The theoretical loop is that enhanced IEQ may positively impact both individual productivity and organisational performance, which could justify the implementation of GBFIs within an office building in an on-going basis. The research comprised four academic articles. The first article was a literature review looking at past research linking green buildings and productivity. This resulted in the proposal of the theoretical model. The second article was a scoping literature review that focused on the main methods that were applied in conducting research between green building and occupant productivity to provide support for the model. Papers three and four comprised empirical research that separately analysed individual productivity and organisational performance. The paper that qualitatively analysed individual productivity indicated that location and amenities, specifically those that focused on safety and reliable building services, positively contributed to individual productivity. The second empirical paper quantitively focused on organisational performance specifically focused on financial services companies (FSCs) and the average green return ratio (AGRRi) within the context green and non-green buildings and IEQ scores. Three funds (low, moderate and high risk) were analysed for each FSC to determine if there was a statistically significant relationship between annualised returns and IEQ, which was only apparent for the South African (SA) equity fund. It was established when comparing the sample of FSCs based in green certified buildings versus conventional (non-green) in terms of group average returns, that the FSCs based in green buildings outperformed the FSCs based in conventional buildings. The differences in annualised returns have been forecasted (compounded monthly and annually), which provides an indication that on average, clients investing in FSCs occupying green buildings will yield great overall wealth over the long-term (thirty years) than clients investing in FSCs located in conventional buildings. It was further established that there was a sweet spot for IEQ scores, which relate to annualised returns for FSCs located in green certified buildings. Based on the qualitative and quantitative findings there is potential for future research to expand the application of the theoretical model to other industries and real estate sectors. Furthermore, this research could be incorporated into environmental, social and governance (ESG) research studies, which could potentially provide justification at the executive level for further insight into unpacking the relationship between individual productivity and organisational performance arising from investing in the quality of the built infrastructure of the office.

    “Youth Enterprising”: Johannesburg Youth’s Motivation, Perceptions and Experiences Regarding Entrepreneurship and Services Provided by the Government and the Private Sector
    (University of the Witwatersrand, Johannesburg, 2023-06) Phofi, Caroline; Pretorius, Edmarie; Dube, Nkosiyazi
    Enterprising and entrepreneurship have become one of the solutions to addressing the challenges of the current economic state in South Africa that seem to have proven to lock some of the youth, especially the disadvantaged youth within Johannesburg, in the cycle of poverty, and unemployment. Although the largest group of youth entering the labour market have shown to be educated and suited for South Africa’s global competitiveness, jobs seem to remain competitive in the formal sector. The study aimed to explore youth enterprising, the motivating factors, perceptions, and experiences of youth towards services that the government and the private sector provides. With the significance of entrepreneurship in the South African economy, there is a need to explore and investigate the contribution of entrepreneurs in the economy of South Africa and how can government and private sector support entrepreneurial activities among the youth to curb unemployment and poverty. A qualitative approach based on the interpretive paradigm was employed to explore the topic of youth enterprising. A case study design was best suited to achieving the objectives of the study, which sought to understand youth enterprise regarding youth’s subjectively constructed reality. The selected case studies were selected from five organisations. These organisations mostly engage in youth development programmes aiming to capacitate youth with psycho-social and entrepreneurial skills, and to provide start-up funding. All the participants for the interviews (n=14), focus group discussion (n=8) and respondents of the questionnaire (16) were selected from Organisation A. The four key informants were from the other four organisations (Organisation B, C, D and E) and were only interviewed. Purposive sampling was adopted to select all the 26 research participants comprising of youth, youth workers, managers and key informants, and the 16 youth participants were selected for the structured questionnaire. The methods of data collection were semi-structured interviews, focus group discussions, and a structured questionnaire. Four different semi-structured interview guides were used as research instruments with all these different groups of participants. A focus group guide was adopted to facilitate the focus group discussion with eight youths. A total of 16 youths completed the hard copy of a structured questionnaire. Due to the COVID-19 pandemic and the national restriction, some potential participants did not want to engage in face-to-face interviews, therefore an online questionnaire was offered as an option so that the research could have more participants to validate the data collection. A structured questionnaire was employed to elicit the respondents’ responses to the four aspects related to motivation, ability, entrepreneurial opportunities, and resources associated with basic entrepreneurial success components. Results from the questionnaire were analysed using descriptive statistics. Data from the different interviews and focus group discussions were analysed using thematic analysis. The findings revealed that business and entrepreneurial skills should be integrated not only into economic sciences but also within the education sector's human sciences and social work courses. Participants mentioned that the role of the government and private sector in youth development and entrepreneurial services is vital. The study findings aided with the development of practice principles and guidelines to be used by social workers and other stakeholders in their programmatic interventions with youth entrepreneurs.
