| Summary: | Sustainable building and construction practices in Malaysia are primarily
aimed at improving the safety and health performance of buildings while minimizing
its impact on resources and the natural environment. Thus, a comprehensive
understanding of the factors that contribute to safety and health performance of our
built environment is essential. The aim of this study is to develop a building safety
and health performance (BSHP) model, focusing on the safety and health
performance factors of low cost housing in Malaysia. These factors include the
architecture, building services, external environment, operation and maintenance,
and management approaches. The influence of these factors on perceived personal
responsibility towards adopting a BSHP model for low-cost housing in Malaysia was
also studied. This study was undertaken in two stages. Firstly, literature on existing
safety and health practices related to low-cost housing and facilities were reviewed to
identify factors that influence health and safety performance. Quantitative data were
gathered to assess the suitability of the factors based on experts judgement and
survey. Data obtained were statistically examined using the exploratory factor
analysis (EFA) and the proposed model was identified. Secondly, quantitative data
were gathered through a main survey involving 308 respondents to test the research
model validity and the proposed hypothesis using the Partial Least Squares (PLS)
tool. Results reveal that the five identified constructs have a direct positive effect on
safety and health performance, as well as perceived personal responsibility.
Furthermore, perceived personal responsibility (β = 0.563) towards safety and health
performance has the highest beta value, followed by building services (β = 0.212),
architecture (β = 0.155), operation and maintenance (β = 0.128), management
approaches (β = 0.124), and external environment (β = 0.117). In testing the validity
of models, results found BSHP model had a good model fit with R
2
of 0.342 and in
line with experts validation results. The BSHP model can inform the public of the
relative risks regarding the safety and health of low cost housing. It can also help
building owners, developers, and government bodies to develop more informed and
socially responsible decisions to improve building safety and health performance. |
