The General Rules for Indoor Environmental Assessment of Long-Term Rental Apartments, which Dansn has edited, has been officially released!


Since the 19th CPC National Congress, especially since the State Council of the CPC Central Committee put forward the concept of 'houses are for living, not for speculation', and launched a series of housing reform measures such as 'renting, purchasing and lifting', the housing leasing market represented by long term rental apartments has been developing vigorously. Since the introduction of a series of housing reform measures such as 'rent and purchase', the housing rental market, represented by long term rental apartments, has been developing vigorously, which has played a positive role in solving the housing problems of urban residents and realizing the principle of 'letting all the people have a place to live.

Recently, the China Association for Standardization (CAS) officially released the group standard 'General Rules for Evaluation of the Indoor Environment of Long-Term Rental Apartments' (Standard No. T/CAS 407-2020, hereinafter referred to as 'General Rules for Evaluation') for the long term rental apartment industry. The standard puts forward the evaluation object, evaluation index, evaluation process and evaluation level of the indoor environment evaluation of long term rental apartments, and explicitly requires long term rental apartment enterprises participating in the indoor environment evaluation to meet the provisions of the relevant national or industry standards, which is applicable to the evaluation of the indoor decoration materials, upholstered furniture or wooden furniture provided in the long term rental apartments (excluding the original owner's self-decoration of the houses), and the third party evaluation of the indoor air quality or self-evaluation of the indoor air quality in the long term rental apartments. Third-party evaluation or self-assessment of indoor air quality. Long-term rental apartment companies participating in the indoor environment evaluation should meet the relevant national or industry standards.


The standard is led by China National Institute of Standardization (CNIS), China Construction News, National Furniture and Indoor Environment Quality Supervision and Inspection Center (NFIQSIQ), China Academy of Building Standard Design (CABSD), China Quality Certification Center (CQC), Beijing Research Institute of Building Materials Inspection (BIBMI), and Shenzhen Chuangniu Information Technology Co.

Focusing on the protection of consumers' physical and mental health, and based on the practical experience of leading enterprises in the housing leasing industry, the Evaluation Guidelines focus on the development trend of more environmentally friendly and healthy technologies, as well as the status quo of indoor environmental quality control by leading enterprises in the industry, and targeting at the main substances in the indoor environment of long-stay rental apartments that have a negative impact on the physical and mental health of consumers, the Evaluation Guidelines are designed to ensure the safety and health of consumers in the indoor environment. The indoor environment evaluation index system for housing leasing enterprises after decorating, configuring furniture and household appliances, proposing restriction requirements and grading the index values.

In recent years, AMBIEN has combined the cutting-edge technologies of inorganic material science and polymer material science to develop subversive and innovative products that combine the physical performance indexes required by different products of domestic green building materials and green home furnishings at the same time. A series of green home building materials, from building decoration to wooden doors, are made by bonding agricultural recyclables and wood fibers with polymer-modified inorganic gelling agents.

In terms of household products, Ambian has developed a new type of fireproof eco-door and a new type of formaldehyde-free, fire-resistant and water-resistant inorganic man-made boards to replace traditional wood and man-made boards; in terms of decorative materials, Ambian's new type of inorganic flooring replaces the traditional wooden flooring or stone-plastic flooring, and the new type of inorganic wall panels replaces the traditional bamboo and wood fiber wall panels and calcium silicate board wall panels, which improves the formaldehyde-free, fire-resistant and water-resistant features while realizing the significant cost reduction. Ambion's innovative technology realizes the control of indoor formaldehyde and other harmful substances from the source, and creates a whole-house space with no formaldehyde, no benzene and low VOC for consumers.

At the same time, AMBIEN complies with the national policy of vigorously developing assembly-type buildings and assembly-type interior decoration, and strictly follows the modular components of the interior decoration industry standard in product design and production. The modular installation of aldehyde-free finished products and the entire dry construction effectively solve the pain points of installation efficiency and vacancy period of long term rental apartments, and is a high-quality solution provider in the long term rental apartment industry.

After the official release of the General Rules of Evaluation, Ambient will continue to abide by its corporate and social responsibilities, and continue to innovate on the road of formaldehyde-free and environmental protection, in order to create a healthier and safer living space for consumers.
