Abstract
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.

An Assessment of Thermal Comfort and Users’ Perceptions of Landscape Gardens in a High-Rise Office Building
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
A cross section of the building in Figure 4 indicates the locations of the three gardens examined. These landscape gardens, located at three different levels vary in design, function and location but have similar building orientation. 2.1 Table 1 summarizes the physical characteristics of the three landscape spaces in Suntech building. 2.1.1 Sky Court Garden This landscape area is located on the 10th floor of the Suntech Building
Summary
An Assessment of Thermal Comfort and Users’ Perceptions of Landscape Gardens in a High-Rise Office Building. Several studies by Westerberg, 1994; Nikolopoulou et al, 2001; Zacharias et al, 2001 have confirmed that there is a relationship between functional use and microclimatic conditions These studies show that comfortable weather conditions such as low temperature and access to sunlight increases the number of people present in an urban space. The objectives of this study are threefold: To measure thermal comfort of different types of landscape garden in a high-rise office building. To examine occupants’ perceptions of thermal comfort, preference and satisfaction of landscape designs of a high-rise office building. To compare between thermal comfort parameter as measured in the field experiment and users’ perceptions of thermal comfort
