Segmentation of buildings in urban areas, especially dense urban areas, by using remotely sensed images is highly desirable. However, segmentation results obtained by using existing algorithms are unsatisfactory because of the unclear boundaries between buildings and the shadows cast by neighboring buildings. In this paper, an algorithm is proposed that successfully segments buildings from aeri...

A major reason why many developing nations have not made significant advancement in sustainable development (SD) agenda is the neglect of existing building stock which forms the bulk of built assets. Although sustainable development is a universal challenge, it cannot be approached in the same way for all nations, but rather practical response can be defined nationally or locally. This paper re...

Research has identified cities as potential urban mines for recovering secondary construction materials. Studies typically focus on stocks or flows of bulk materials high abstraction levels. To enable a shift toward higher levels circular economy, such waste minimization, there is need more detailed understanding the dynamics that contribute to flows, building replacement in particular. This pa...

Since the 1990s, China has implemented policy of “suppress second industry and develop third industry” in order to promote adjustment social economic structure, thus begun face industrial transformation. As time goes by, material language existing buildings gradually conveys a broken, desolate expressiveness, which makes people have certain “sense fright caused by fracture time”, it also brough...

High energy consumption in regions with harsh climatic conditions makes it difficult to reach targets. This study considers design decisions affecting for cold climate regions; the position of building, its orientation, building envelope elements and materials were examined. In line these decisions, a field was conducted by researching energy-efficient renovation existing social housing structu...
