The current situation and trends of healthy building development in China

Abstract

The development of healthy buildings is an important way to implement the strategy of “Healthy China” in the building industry. It is of great significance to promote the development of healthy buildings. In 2016, China’s first healthy building technical standard Assessment Standard for Healthy Building was released and implemented in January 2017. Since then, the healthy building has achieved rapid development in China, which is embodied in the following aspects. (1) Set technical standards to lead the development of healthy buildings. To realize the fine construction guidelines, in addition to Assessment Standard for Healthy Building , technical standards for healthy buildings have been compiled for major building types, such as healthy hotels and healthy hospitals. In addition, on the basis of single building, assessment standards such as healthy community and healthy town have considered the healthy influencing factors in different scopes and put forward the corresponding technical requirements. (2) Conduct the scientific research to provide theoretical and technical supports for the development of healthy buildings. The researchers carried out special scientific research from the aspects of building ventilation, indoor air quality, emission of pollutants from building materials, healthy lighting and light environment improvement, sports health and so on. (3) Various organizations provide services for the healthy building industry. First, the healthy living professional group of China association for engineering construction standardization (CECS) was established to promote the standardization of healthy buildings. Second, China Healthy Building Alliance plays the role of link, carrier and platform to establish a diversified channel for sharing healthy building resources. Third, the relevant research institutions were established to conduct special research on the theory and technology of healthy buildings. (4) Carry out project evaluation to drive the implementation of healthy building projects. Chinese Society for Urban Studies (CSUS) has carried out the evaluation and certification of healthy building. By September 2019, a total of 50 projects had obtained the certification of healthy building identification, covering 14 provinces and cities with a total building area of nearly 5 million m2. (5) Promote healthy building technology progress through academic exchange and technical cooperation. Taking 2019 (the first) Healthy Building Conference as an example, academicians, experts, executives and other representatives from different fields exchanged views on healthy environment research, standard certification, scheme supply, case demonstration and industrial value, which gave new momentum to the development of healthy buildings. However, the healthy buildings are still in the initial stage in China. In the future, more comprehensive exploration and innovation should be carried out in the following aspects. (1) The identification of factors affecting physical health, mental health and social health related to healthy buildings and the mechanisms of healthy impact need further exploration. (2) It is necessary to promote the interdisciplinary development of healthy buildings, realize the interdisciplinarity and integration, and solve the scientific problem as a whole. (3) In the design stage, comprehensive pre-evaluation is carried out on the factors affecting human health, and the health is integrated into the design of buildings and communities, and healthy design technology is studied and developed. (4) The research on technical standard system of healthy building should be carried out to establish a standard system covering different types of buildings in different stages of the whole life cycle. (5) It is urgent to strengthen the research and development of the related theories, standards, technologies and supporting products of the existing buildings and communities.
