There is a great need to reduce energy consumption in high-rise office buildings due to escalating environmental problems such as Urban Heat Island effect and global warming. The creation of landscape spaces in high-rise buildings today is not only for reducing building heat but to provide views and psychological get-away spaces for its occupants. This paper focuses on thermal comfort and users’ perception of three different landscape gardens in a 21-storey high-rise office building in Penang, Malaysia. The four parameters of thermal comfort that were measured are: air temperature, wind velocity, humidity, and solar radiation. In addition, a questionnaire survey was conducted to evaluate occupants’ perceptions of comfort, use of the garden space and landscape preference. The findings from the field measurement reveal significant differences in all four thermal comfort parameters measured in the three landscape gardens. However, users only perceived lighting and wind velocity to be different.
