Sustainable housing and urban construction in China
Section snippets
Background
Given the construction boom since 1990s, China has been experiencing a high growth of total output value of construction industry, and an annual average speed of 11% was achieved over the past 5 years [1], [2]. The residential and commercial building floor area increased by 1.6–1.9 billion square meters and resulted in a steady growth of total building stock [1], [2]. Meanwhile, the possession ratio of household air-conditioners for per 100 families in South China was increasing at a speed of
Best mode for the development of sustainable buildings in China
The sustainable building is also called ‘ecological building’ and ‘green building’, which is also well known as ‘energy efficient building’ and ‘healthy building’. Only technology aspects relative to energy and environment are concerned here for the sustainable building instead of aesthetic aspect in order to consume as less as possible energy and any other resources, be nature friendly and be healthy to the occupants. Since the energy crisis of 1970s, some developed countries contributed a lot
Difference between strategies for residential buildings and commercial buildings
Both the residential buildings and commercial buildings require good indoor climate and outdoor climate. However, these two kinds of buildings should be taken under different technical strategies because they have different building constructions and internal heat gains. The commercial building usually has larger area of inner zone and more internal heat gain than the residential building. Contrary to the commercial building, the indoor climate of the residential building is affected more by
Conclusion
So far, based on the analysis of the requirements, characteristics, standards for evaluation and the feasibility for sustainable housing and urban construction in China, series technical approaches and suggestions in different design stages of the construction of a building are introduced and recommended. These technical approaches are based on the research achievements of School of Architecture, Tsinghua University. Some of the technical approaches for a sustainable design need good
