In the past 30 years, much effort has been directed to
make building performance simulation become
inherent in architectural practice. Anecdotal evidence
however shows that it still a long way for this goal to
be achieved. This paper presents the outcome of a
survey conducted in Australia, India, the US and the
UK, to investigate difficulties that architects have to
overcome in their day-to-day practices and identify
the reasons why using building performance
simulation, regardless how friendly the tools are, is
still not and may never be in the mainstream of their
practices. Based on the survey, the paper proposes a
number of recommendations to overcome this
challenge in line with IBPSA’s vision on bridging the
gap between research and practice
