Starting from March 1, the common standards of new civil buildings have begun to implement, and the more discussions are the calculations of the construction area.

The new regulations stipulate that the building area should be calculated according to the horizontal projection area of the outer surface of the outer surface of the outer surface of the outer surrounding structure at the surface of each natural floor (ground) surface of the building, which means that not only the peripheral building walls, but also glass as the peripheral protection structure glassThe curtain wall, metal curtain wall, stone curtain wall, artificial board curtain wall, etc. are also included in the construction area.

In fact, on August 25, 2022, the official website of the Ministry of Housing and Construction issued the announcement of the common standards of civil buildings (the national standard number GB 55031-2022), and pointed out that this specification is a compulsory engineering construction specification. The new regulations on March 1 this year are officially implemented.After that, all the provisions must be strictly implemented.

If the relevant provisions in the current construction standards are inconsistent with this specification, the provisions of this specification shall prevail.

So, what impact will the new rules have on buyers?Chen Xiao, a senior analyst of Zhuge Data Research Center, told Hongxing reporter that the cost of buying houses may increase for buyers.

According to the new regulations, the outer wall layers must be included in the construction area, and the building area of the house increases, but the actual inner area has not changed. Buyers want to buy houses in the same inner area as before.the cost of.

For example, Chen Xiao said that, for example, buyers buy a house with a building area of 100 square meters. According to national regulations, the household stall rate below 11 floors is about 7%-16%, and the pool rate of more than 12 floors is 14%-About 24%, the public roll area is 7-24 square meters, and the actual inner area is 76-93 square meters.

If the outer wall layer is included in the building area, the bars may increase, and the corresponding inner area will be reduced.

However, Chen Xiao said that there is no need to worry too much, because the thickness of the surface layer layer of the commodity house is generally about 20mm. Although the pool rate has increased, the gap between them may not be too large, and the housing and design institutes mayMore considerations will be needed.

Yan Yuejin, the research director of the E -House Research Institute, believes that there are many discussions on the area of the publicity. The new computing formula of the construction area will objectively reduce the actual house rate of buyers.

This also requires all localities to explain more when implementing such policies.At the same time, such policies are objectively helping standardize the development and construction of housing companies.In the past calculation methods, there were a lot of building design in various types of stealing area, which also caused many architectural quality problems and design problems behind it.The new regulations help ensure the development of housing enterprises and reduce various small actions.

Li Yujia, chief researcher of the Housing Policy Research Center of the Guangdong Provincial Urban Rules Institute, told Red Star Journalists that the new regulations also need to give a specific explanation of the housing and construction department, because the confirmation of the construction area will eventually be based on the surveying and mapping of the housing and construction department.

Compared with the previous regulations, the new regulations mainly specify that the exterior wall is included in the construction area. I think that the main purpose is to encourage developers to not use glass curtain walls such as glass curtain walls with high energy -consuming and large light pollution.In addition, from the perspective of the management of the whole life cycle of the building, if the exterior wall is included in the house area, the investment in this part will increase, which will help improve the quality of life of the house.
