Indoor decoration pollution caused by the use of unqualified decoration materials or unreasonable design is becoming a new environmental pollution and has attracted much attention. According to media reports, in recent years, there have been many long-rental apartment brands that have complained about the overdue of formaldehyde or related problems.
The long-term rental apartment is essentially the property that the operator has rented out after the property has been taken out of the room. The renovation can be described as the core element of this format. Due to the characteristics of “staying in the bagâ€, the long-rent apartments with “interior decoration†than the ordinary rental houses are more and more popular. Especially in 2017, the scale of China's housing leasing market has reached 1.1 trillion yuan. It is expected that by the year 2030, it will reach 4.6 trillion yuan (chain home data), and more and more capital is pouring into the long-term rental apartment industry.
In the early stage of the development of the long-rental apartment “horse raceâ€, on the one hand, it is the rapid expansion of the format, on the other hand, it is the core element of the long-term rental apartment – ​​the “renovation†problem is constantly emerging.
Short decoration period, problem looming
As a commercial operation, long-term rental apartments must consider their costs and profits.
It is understood that in the long-term rental apartment "take project, decoration, operation, management" four major links, decoration is the most cumbersome, but also the most costly operation space.
People in the long-term rental apartment sector told the reporters of the Daily Economic News that long-term rental apartments can often achieve differentiated "features" through decoration to achieve their greater appeal. However, the quality of the decoration is not easy to be noticed, and there are no standards for long-term rental apartments. The requirements for each operation are different, and there are strong and weak.
However, it is revealed that the standard of decoration for ordinary long-term rental apartments will not be too high. The average key second-tier cities are often less than 500 yuan/square meter, and the renovation time will be as fast as possible, because "the house is down, the longer the shelf life is." The higher."
After "low" and "fast", the problem may appear. According to media reports, the formaldehyde content of a long-rent apartment in Beijing is as high as 0.7mg/m3, which is several times higher than the national standard.
Mr. Xu, the manager of a large-scale housing company responsible for air testing of house decoration, told the reporter of “Daily Economic News†that in general, if the decoration is completed within one month, the (related index) must be exceeded. Because furniture is an uncontrollable material, some plates (floors) will release harmful gases after heating, and formaldehyde will volatilize at room temperature above 19 degrees Celsius.
The person in charge of the Rubik's Cube apartment also told reporters that the long-term rental apartment is usually rented out by the operator after the house is refurbished, so the quality of the decoration and the environmental protection of the decoration materials are often determined by the operator's attitude and choice. This will directly affect the quality of the internal environment of the house. Therefore, the Rubik's Cube apartment generally requires a period of about 6 months from the start of the property renovation to the stay, and the renovation period is about 120 days.
Raw materials are also the focus. Mr. Xu told reporters that long-term rental apartments are generally “toolingsâ€, that is, they are uniformly contracted by the decoration company and there is room for operation. For example, the board has E0 grade, E1 grade, E2 grade, etc. It may cost tens of dollars for a board to differ by one grade; the difference of the floor is also great, such as particleboard, fiberboard, blockboard, multi-layer board, etc. The template uses urea-formaldehyde resin synthesized from formaldehyde as the binder; the dye used in the inferior curtains may also exceed the standard; the additive of the paint is also closely related to the cost... Therefore, it may appear during the decoration period. The quality of raw materials is not up to standard.
“At present, the formaldehyde concentration in accordance with national standards is less than 0.08 mg/m3. If it is higher than this point, the indoor environment will be unqualified. From a professional point of view, unless the ventilation is better, the problem of staying within half a year is not big, generally need to dry. More time," said Mr. Xu.
Long-term rental apartment decoration lacks environmental standards
In recent years, some decorative materials in China have been exposed to excessive levels of carcinogens such as formaldehyde, benzene, xylene and xenon. With the increasing awareness of people's health and environmental protection, these problems have gradually attracted more attention and even concern.
However, in terms of the decoration section of the long-term rental apartment, the person in charge of the above-mentioned apartment bluntly said “more ambiguousâ€. China's current implementation rules and related constraints on long-term rental apartments are not perfect.
For example, in terms of decoration materials, long-rent apartments operated by developers such as Longhu Guanyu, Vanke Po, and Ocean House have their own fixed material suppliers, and the collection mode can also monitor quality and cost. But there is still no regulation. All kinds of apartments operate according to their own methods, and because they want to form a differentiated advantage, they tend to be "unconventional" in terms of room decoration color, configuration, interior style decoration style.
It is understood that there is no environmental protection standard for long-term rental apartments, but this year Zhejiang issued the "Fire Safety Requirements for Residential Rented Houses in Zhejiang Province", which stipulated the per capita area, the number of beds and the number of evacuation passages, and since August 1 this year. Since the beginning of the day, there has been a higher “Fire Standard for Zhejiang Rental Housingâ€, which has released a signal for the long-rental apartment industry to pay attention to the environment and improve safety.
Before the introduction of all-round official standards, the above-mentioned industry participants said that enterprises should start from their own improvement.
The person in charge of R&D and construction of Rubik's Cube said that the set of rules is to meet the requirements of materials selection, ensure that the selection meets the national standards, avoid the use of materials that are prone to pollutants, and control the problem of formaldehyde exceeding the standard from the source; In the construction process, the basic standards for construction materials are unified, and the basic materials of each project are strictly controlled.
There are many formaldehyde control institutions in the market. If long-term rental apartment operators or users want to avoid harming their own health, they can find a qualified third party to conduct an overall indoor air test on the property. In particular, operators can issue CMA measurement certification qualifications (ie, inspection qualification test reports) after testing, even if there is a legal dispute in the future.
If you are about to stay, it is best to take the ventilation time from the perspective of the testing organization. This is the best solution. In addition, there are some emergency solutions, such as the ability to install fresh air systems, as well as some air purifiers with formaldehyde removal, green plants, etc.
“In fact, for long-term rental apartment operators, the key point is to truly realize the long-term win-win relationship between merchants and households, to put the safety and health of residents at the top of development, and to coordinate speed, safety and quality. Relationship," said Mr. Xu.
