Long-life housing is a type of housing available for about 100 years through replacement of its infills with its supports maintained for a long time. Yet long-life housing is not spread smoothly because of the lack of policies and publicity. In particular, considering the perception that initial construction...

In this paper, the traditional silt house of Wa ethnicity in Yunnan province would be researched as an example based on field measurement and Ecotect software simulation, and the characteristics and existing problems of natural lighting in silt houses were studied. The transformation strategies of the...

Long-life housing is a type of housing that can accommodate the function and performance to meet the needs of society and residents by changing and replacing infill parts such as exterior parts, interior parts and facilities that have a short life and are sensitive to social and functional changes while...

The current regulations related to building are scattered in more than 370 individual laws. Since the amendment of existing regulations and the legislation of new regulation have been going on, it is difficult to grasp the relevant regulations.
