1, what is a healthy building?
1996
Since, the European Office of the World Health Organization (WHO) has carried out the Healthy City Plan, put forward a guide to healthy cities, and listed a number of health indicators, missions, prospects and directions for countries' reference, so as to design sustainable cities with science and wisdom.

At the international architecture conference, a healthy building is defined as "a way to experience the indoor environment of a building, which includes not only physical measurements, such as temperature, humidity, ventilation rate, noise, light and air quality, but also subjective and psychological factors, such as layout, environmental color, lighting, space and materials used." ; In addition, important factors such as job satisfaction and interpersonal relationship also need to be added. A healthy building must meet all the above requirements. "Research and practice show that healthy buildings are closely related to urban development, social harmony and people's physical and mental health. In order to ensure a foothold, the future secondary builders should keep the personal knowledge of body double and conform to the development trend of the international construction industry.
2, healthy building evaluation criteria
1990, the British "Building Research Center" launched BREEAM, the world's first comprehensive evaluation system for green buildings, taking health and comfort as one of the indicators for evaluating buildings, followed by LEED standard in the United States, DGNB, the second generation evaluation system for green buildings in Germany, and GB/T in China.
50378 "Evaluation Standard of Green Building" contains related indicators of health and comfort.
Until June 20 14 and 10, IWBI released the version of WELL healthy building evaluation standard 1.0, which is the first building evaluation standard for people's health and comfort in the world. 20/kloc-in March, 2005, Green Building Certification Association (GBCI) and International Weir Building Association (IWBI) formally introduced Weir building standards into China. On October 20 17 10, China Architecture Society issued and implemented T/ASC02-20 16 "Evaluation Standard for Healthy Buildings".
3. China T/ASC02-20 16 Health Building Evaluation Standard.
T/ASC02-20 16 《 Evaluation Standard for Healthy Buildings 》 incorporated the mature three-star evaluation system into the standard and set it as three grades, with 50 points for one star, 60 points for two stars and 80 points for three stars. There are 25 preconditions. If they are unqualified, they will not be able to participate in the evaluation of healthy buildings, and the evaluation object will be expanded from residential buildings to civil buildings. The evaluation index system in this standard is divided into six indexes: air, water, comfort, fitness, humanities, service, improvement and innovation. Encourage construction units to improve their performance through innovative means, innovative methods, innovative technologies and innovative products. Air indicators include reducing air pollution sources, and the concentration of pollutants shall not exceed the standard. Comfort indexes include acoustic environment, light environment, thermal environment and ergonomics. Air, water and comfort refer to monitoring measures, including air quality monitoring and water quality monitoring. Fitness indicators include indoor fitness facilities and outdoor fitness facilities, fitness guidance. Humanities include communication, mental health and architectural importance. Services include property management, publicity, daily activities and publicity. This also puts forward new professional requirements for secondary builders. The second-level constructor must develop in the direction of health, environmental protection and humanity in the future to ensure that the project meets the standards.
The above is the introduction of healthy buildings. A healthy building is not only closely related to people's physical and mental health, but also closely related to the healthy development of the city. Accelerating the development of healthy buildings has become a new direction of green building industry. Under the development trend of healthy buildings, secondary builders have a long way to go. As secondary builders, they should not only adapt to the social trend, but also improve their personal skills in time.
