This paper analyses the historical pre-Colonial configurations of a series of urban cores in Malay sites along the Straits of Melaka. The objective of this research is to identify the pattern and variations of each pre-Colonial royal urban core from the perspective of urban design principle such as “intimacy” and “walkability,” which can affect in a long term sustainable parameters such as the reduction of “urban heat island”. This traditional character is increasingly disappearing due to urbanisation. There is a difficulty to reconstruct the urban core of these case studies because of their past layouts’ degree of organic character, particularly in terms of randomness. This paper argues that such configurations reflect the degree of “intimacy,” which was ruptured during the Colonial eras. Patterns were identified using available maps and lithography related to the case studies. The findings indicate that the Malay royal urban core does obey the urban design principles of intimacy and walkability. The “intimacy indices” for a historical Malay city are as follow: distance from palace to mosque (170 metre), padang/open spaces (130 metre), settlement (310 metre), market (195 metre), and aristocrat houses (60 metre). This finding can be used to inform the baseline for the preparation of the Malay principles guidelines.

Owing to the urban heat island effect, the urban design and planning have been encountered the severe plights. Based on our observational research show that each year in Taiwan during the summer season, the urban and rural area temperature difference of up to 3-8 ℃; our numerical simulation results show the environmental thermal forcing effect is quite significant during the occurrence period of the urban heat island effect. And environmental wind field was forced to change (from the original northwest wind to southwest wind), a rapid increase in the moisture field (the relative humidity up to 90%), convergence was forced in the low level, upward motion derivative is excited, and result show the unexpected afternoon thunderstorms phenomenon occurred on the urban region.On the vicinity of the architecture building or the urban construction region, planting the large arbor that the carbon sequestration force was strong (about 900 kg / m2 / yr), by thinking about to adjust planting location, direction, height, area, density, and design, to guide the suitable environmental wind field, it will effectively mitigate the urban heat island effect.

Abstract BackgroundIncreasing urban heat island and global warming have aroused serious thermal environmental problems, even do harm to people’s thermal health. Because the importance in people’s daily life, Commercial pedestrianized block represents a symbol of a city or metropolis, therefore, focusing the attention on the thermal environment in such regions is very necessary. Most of the researches on urban thermal environment are calculated by remote sensing data, limited by the low spatial resolution of remote sensing image, it may not obviously reflect the true thermal environment of the research site, especially in some micro-scale regions. MethodsBased on this, the new software ENVI-met is developed to research the thermal environment and forecast people’s thermal sensation in micro-scale region. ResultsTherefore, the objective of this study aims at conducting field measurement and numerical simulation to assess the thermal environment of a typical commercial pedestrianized space in southern China, and assess the different urban design parameter in ameliorating urban heat island effect. ConclusionsOur final results demonstrate a quantitative evidence for establishing a comprehensive standard for improving thermal environment in micro-scale region, and this study also can be a supplementary in the research field about improving thermal health.
