Abstract

Purpose

In the era of climate change, the need to ensure that buildings are energy efficient cannot be overemphasised. Studies have shown that building retrofitting can improve energy efficiency (EE) and sustainability. There may be hindrances to retrofitting for energy efficiency. Extant literature and policy documents on Zimbabwe suggest a better framework to help stakeholders manage their existing buildings by addressing challenges and policy inconsistencies. This study appraises and critically discusses the challenges facing retrofitting Zimbabwe’s buildings for energy efficiency.

Design/methodology/approach

The research adopted a quantitative research design using a questionnaire survey distributed to the respondents knowledgeable in building retrofitting and energy efficiency in Zimbabwe. The data were analysed through various statistical approaches (descriptive and inferential). The inferential tests include the Shapiro–Wilk test, Kruskal–Wallis H-test, exploratory factor analysis and heterotrait-monotrait ratio analysis to develop the structural equation model that validated the challenges for retrofitting buildings.

Findings

The results revealed the challenges of retrofitting buildings for EE in Zimbabwe, and a structural equation model was developed that clustered the key challenges into three main groups. This includes inadequate finance to invest in energy, outdated building by-laws and the unavailability of raw materials to achieve energy efficiency.

Originality/value

By appraising the challenges facing retrofitting buildings for energy efficiency in Zimbabwe, this study provides insights into the contextual factors that can enhance energy efficiency and sustainability in other developing countries. The study’s practical implications will positively impact the Green Building Council and other stakeholders interested in improving energy efficiency in the built environment.

Abstract

Purpose

The regulation of the construction industry remains a significant obstacle to economic progress in developing nations. Therefore, this study aimed to assess the efficacy of the legislative framework in the construction industry, focusing on Eswatini. The construction industry plays a critical role in the upliftment of the economy and an effective and efficient legislative framework is essential to ensure that as a developing country, Eswatini derives maximum benefits from the sector.

Design/methodology/approach

A phenomenological research design was used to explore stakeholders’ perceptions about the purpose of the legislative framework in the Eswatini construction industry and to establish the effectiveness of the current legislative framework in fulfilling its mandate. The data were collected using semi-structured interviews with open-ended questions. A total of 45 participants occupying different positions within the construction industry were selected using purposive sampling. The data were analysed thematically.

Findings

The results reiterate that the legislative framework’s purpose is to regulate, control and guide sectoral operations, including enforcing compliance with statutes and payment of construction levies. However, the legislative framework does not effectively fulfil its purpose of addressing stakeholder needs. Overall, the findings indicate shortcomings and inefficiencies within the framework aimed at regulating the construction industry of Eswatini. The inefficiencies have a great potential of defeating the purpose of the entire framework.

Research limitations/implications

Regarding implications for future research, the current study has set a new pathway for legislative framework analysis and evaluation. Therefore, future research on the topic can build on the current study and compare the legislative frameworks across developing countries. The purpose would be to establish the similarities and differences, and to identify strengths and weaknesses, possibly leading to established principles of what works in a given context. Other studies on the topic could focus on benchmarking against developed countries on how they measure the efficacy of the legislative framework within their constriction industry.

Practical implications

Based on the preceding, these findings may apply to similar developing countries at a similar stage of construction industry development. However, the findings should be considered within the limitations of the study. The focus was on developing countries, particularly the Eswatini context. Each country presents a unique context and challenges, so the findings should be cautiously generalized.

Originality/value

While other studies in different contexts focus on developing legislative frameworks, the current study evaluated an existing legislative framework using defined criteria. The current study made a unique contribution by streamlining the features of effective and ineffective legislative frameworks. Hitherto, such information was scattered in literature but has been consolidated and applied empirically. Thus, the study has set benchmarks for analysing and evaluating legislative frameworks in developing countries.
