Abstract
Green building technology (GBT) is the application of processes that are
environmentally responsible and resource-efficient throughout a building's life-cycle.
GBT has raised the public’s awareness in recent years due to global climate change. The
construction industry is also aware that natural resources will be depleted if it does not
practise sustainable development. Based on the fact that the design of built environment
has various impacts on all of us, experts are beginning to focus on the design and
construction of buildings using sustainable practices that will support the construction
industry with a more responsible way to manage natural resources. Global construction
output is predicted to grow significantly by year 2030. In order to preserve our
environment for future generations, it is important to implement GBT in the building
construction industry. Despite the enormous benefits of GBT, the implementation of
GBT in Malaysia is still considered as slow due to various challenges. This study aims
to determine the challenges and benefits of GBT implementation and to measure the
weightage between the challenges and benefits of implementing GBT from sustainability
perspectives. The result from questionnaire survey shows that the challenges of GBT
implementation are more significant than the benefits of GBT implementation. The most
significant challenge is “the role of government in promoting green building technology”
with a Relative Importance Index (RII) of 4.54, out of 5.00. It is expected that this study
can assist the construction industry’s stakeholders to understand GBT implementation
for decision making and policy development, besides can be used as a reference for future
comparative studies.
