Abstract

The rapid urbanisation especially in Sarawak has transformed current environment from natural vegetation to engineer structured. This built up environment give significant impact on the outdoor thermal environment due to the rises temperature in urban areas. Building arrangement and its building layout patterns is also a parameter in influencing the radiation of air flow in and outside of the buildings. This building characteristics that lead to UHI not only found in city areas but also can be found in university campus area such as UNIMAS where there is also existence of various type of building layout patterns, high rise building and compacted building area. Furthermore, the study of thermal comfort in university area have not fully explored. Therefore, this study aims for outdoor thermal comfort assessment that conducted in Universiti Malaysia Sarawak (UNIMAS) where the different building layout patterns have been found which might contributes to higher heat impacts. This thermal comfort assessment was conducted by using subjective measurement through questionnaire survey and the data obtained was analysed using SPSS software. The results indicated that the Sakura College building have contribute to higher heat impact where 42% of the respondents feel hot. While, for Cempaka College and Reservoir Park, the result showed that only 30% and 17% of the respondents feel hot respectively. The thermal environment at Sakura College was founded to be the most critical place due to the building arrangement which is directly exposed to the sunlight and causes 61% of the respondents to feel uncomfortable while doing their activities. The shading effect due to the building arrangement of Cempaka College helps to protect the respondents from exposed to direct sunlight and makes 55% of them feel comfortable. Meanwhile, the presence of vegetation area such as tall trees and water body helps in regulating the air movement in Reservoir park where 87% of the respondents feel comfortable during carry out their activities. Based on the overall results, it can be seen that the respondents at three different locations are able to accept and adapt with the current thermal environment. However, most of them are preferring the locations especially Sakura and Cempaka College to be cooler in the future. Lastly, throughout this study, it hope to be useful and able to propose proper building arrangement by considering the effect of different building layout patterns on thermal environment especially for university community.
