Rapid growth of urban population and urban area during the past 30 years in Bandar Abbas city with hot and humid climate has been regarded as the major concern of urban designers and planners. In modern fabric climate response urban design has been ignored. This paper investigates the microclimate principals of two different fabrics in South East of Bandar Abbas using different thermal comfort indices and microclimate assessment of residential urban canyons. Fieldwork studies in two different fabrics indicate that traditional fabric of study area can have good potential to be called a thermal comfort environment if its vegetation and building environment is modified and integrated in the design appropriately. The finding can be used as reference for urban planners and urban designers and municipality experts of the cities which posses the same climate.

Increasing the country population and the trend of industrialization caused increasing Malaysia's electricity consumption. Light Emitting Diode (LED) is a new sustainable technology that has taken over the conventional lighting in built and environment in a few developed counties in the recent years. However, Malaysia is left behind in using this technology due to unfamiliarity of the decision makers on its advantages. The research is using a mixed qualitative and quantitative method for finding advantages of LED for lighting the streets and built and environment. A group of scholars traveled to Canada and USA and observed seven factories and interviewed 40 professional of LED and discussed use of this technology in the context of Malaysia. The result of those observation and interview is synthesized and presented in this paper. The conclusion of this research confirms despit all LED advantages, it is very high cost in term of replacement, primary investment and maintenance.

Accessibility to thermal comfort spaces for citizens and urban outdoor activities could be one of the main goals of urban designers. The objective of this paper is to conduct a comparative study on two different urban fabrics, using thermal comfort and Computational Fluid Dynamics (CFD) methods. Results relate the effects of urban canyon's orientation on variation of the microclimate factors and consequently, on the thermal comfort situation in the hottest period of the year. The results indicate that traditional urban fabric is more thermally comfortable than the new residential urban fabric. According to the field measurements, thermal comfort calculation, and wind simulations, the canyons with North-South direction represent a better orientation for air circulation benefiting from sea breezes as compared to other canyon orientations. The result will throw light for the urban designers and policy makers of hot and humid climate in the Middle East.
