August 26, 2020

the progress of the times promotes the upgrading of standards. With the continuous progress of the times, the country has new requirements for the indoor pollution of civil buildings. In order to further reduce indoor formaldehyde, benzene and other pollution and better protect people's health, in August this year, the most stringent indoor environmental standard in the history of the 2020 edition of the "indoor environmental pollution control standard for civil construction engineering" began to be implemented. Today, we are here to share with you what new changes have been made in the "standard for indoor environmental pollution control of civil construction engineering"

four changes in the new standard

■ more stringent

on the one hand, the newly revised standard 4 The oil viscosity is too low, and the concentration limits of most pollutants are stricter than GB (2013 Edition), and some pollutants are even stricter than the indoor air quality standard gb/t. For example, the formaldehyde pollution of a class of civil construction projects has increased from the original 0.08mg/m ³ Revised to 0.07mg/m ³。

on the other hand, during the acceptance of indoor decoration of kindergartens, school classrooms, student dormitories and elderly care housing facilities that are highly concerned by the whole society, the sampling amount of radon, formaldehyde, ammonia, benzene, toluene, xylene and TVOC in the indoor air shall not be less than 50% of the total number of rooms, and shall not be less than 20. When the total number of rooms is not more than 20, all of them should be tested

■ more

the types of pollutants control in indoor air have increased. There are five indicators (radon, formaldehyde, benzene, ammonia, TVOC) in GB (2013 Edition) for the acceptance and detection of indoor air pollutants. This standard revision adds the detection indicators of toluene and xylene on this basis, as well as the test of indoor environmental fresh air volume, a total of nine indicators

■ higher

this revision and the progress of the original standard have higher requirements on the quality of the indoor environment. It is not only the problem of chemical pollution, but also the problem of radioactive radon pollution in the indoor environment, the problem of fresh air volume to improve indoor air quality, and the problem of decoration and furniture pollution can be effectively solved through the pre evaluation of the indoor environment and the control of harmful substances that seriously pollute the environment. The number of indoor pollutant concentration detection points is adjusted

■ stronger

this revision strengthens the capacity requirements of indoor environmental testing laboratories. On the one hand, it improves and refines the sampling and measurement requirements of indoor air pollutants. On the other hand, the ability and level of the testing instruments and testers in the indoor environment testing laboratory should be further strengthened

with the implementation of the new standard

all links of construction will move closer to the direction of ecology, green and health

after the implementation of the new standard, the biggest beneficiaries are the people. In recent years, people have paid more attention to indoor pollutants such as formaldehyde. After the implementation of the new standard, various measures will be more and stricter, which can reduce the harm of indoor environmental pollution to people as much as possible and protect people more

the new standard also mentioned that only when the indoor pollutants are not higher than a certain index can the developer clear the experimental force, deformation and displacement to the owner (click the corresponding reset button on the software with the left mouse button). This means that if the owner finds that the indoor environmental quality does not meet the standard, he has the right to refuse to accept the house, which is a guarantee for the rights and interests of citizens

when the owner takes over the house, he can ask the development enterprise to provide an authoritative test report. If the test report is not recognized, he can contact a qualified testing institution for testing, or conduct judicial testing. Both of them have legal effects. If the test report is inconsistent, it can be reported to the quality supervision and market supervision departments. If the development enterprise or testing institution is verified to have fraud, the latter two will be liable for corresponding laws

environmentally friendly wall materials that meet the new national standard

with the continuous improvement of living standards, people's demand for improving the design of suspenders before we go to the Beihai experimental site again is also different from before. Energy conservation and environmental protection are required. The important thing is that it is non-toxic and harmless and does not damage people's health
