Due to the development of the social economy and people living standard rise, the public has produced great changes to the requirement of the interior design, for interior designers professional ability is also put forward higher requirements. As the main position of interior design talent cultivation, universities of professional interior design must be according to these changes, corresponding education reform. Reform must be from the construction of curriculum system, teaching content and teaching method and so on as all aspects of interior design education to promote at the same time, in order to achieve their purpose. Our research proposes the novel paradigm for the interior design education which will enhance the current teaching mode.展开更多

In the tropics, the outdoor thermal comfort conditions during daytime are often far above acceptable comfort standards due to intense solar radiation and high solar elevations. This study aims to know effects of simple and fundamental building forms on microclimate and outdoor thermal comfort in a high dense tropical city, focusing on Dhaka, Bangladesh as a study city. Investigations are carried out on existing area and model areas with modified building forms （in respect of height and shape） on the microclimate as well as on outdoor thermal comfort during daytime in summer. This study has demonstrated that the model using less ground coverage and higher buildings can offer a better thermal climate than the models using maximum ground coverage in a high-density tropical city.展开更多
