Abstract: Buildings are one of the important energy consuming sectors. The increasing environmental
awareness has triggered a great emphasis on sustainable design in the current global building
industry. Since the past century, there has been a distinct growing trend in the use of fully glazed
façade in office buildings. This paper discussed and analysed how solar control and natural ventilation
systems can be integrated into double skin façade systems to minimise the environmental impacts.
Sun shading should be considered as an integral part of fenestration system design that is adapted into
the façade design of office buildings. The technology of façade systems that integrate solar control and
ventilation systems encompasses a wide range of strategies and options resulting in energy efficient
building design. Such façade systems minimise overheating and excessive solar gains during summer
whilst increasing direct solar gains during winter to minimise the use of mechanical heating. Through
case studies, this paper examines the performances of different double skin façades systems.
Evaluations and recommendations are made to enhance the future designs of glass façade systems.
