Let me ask you an ignorant question. What is an existing house with a banlou?

Judging from the architectural characteristics of banlou, banlou is a building with long east and short north and south. At present, many banlou buildings on the market are indeed variants of towers. In order to cater to the preferences of current buyers, many developers make their buildings look like plate houses. If they go deep into the room, they will find that many units are no different from towers. Identifying whether a house is really a banlou depends not only on the shape of the building, but also on its interior. The layout of the banlou should be wide in the south, short in the depth and transparent in the north and south. In the case of north-south window opening, convection can be formed through natural ventilation. There are many so-called banlou units in the market now, but they are not transparent from north to south, and even some banlou units are purely north-oriented units. This is not much different from the tower. Although some units are transparent from north to south, the depth is 17 meters, or even larger, resulting in darkrooms in all rooms. In this way, the ventilation and lighting effect of the board building is greatly reduced. According to experts' standards, let's measure whether Huigu Sunshine, which wants to "expose all fake board buildings", can meet the requirements of real board buildings. Mr. Luo Lijun, executive deputy general manager of Beijing Sunshine Ye Jia Real Estate Development Co., Ltd., the developer of Huigu Sunshine, told the reporter that Huigu Sunshine is a pure board building community, and the first phase has been moved in. Not only does the architectural modeling conform to the ratio of length, width and height of the board building, but the indoor apartment design also strictly abides by the requirements of the board building. The design of one staircase and two households eliminates the pure north-facing apartment type. The depth is 1 1.8m, and the width is 4.5m The characteristics of large width and short depth fully meet the needs of ventilation and lighting. At the same time, Mr. Luo Lijun also pointed out that the thinner the banlou, the better. Excessive pursuit of "thinness" may also lead to unreasonable distribution of indoor space. "Thin plate" is to reduce the thickness of the building as much as possible without affecting the functional division and square sense of the indoor space, so as to increase the indoor permeability and the light reception per unit area. The depth of 1 1.8m is the ideal value of north-south two-way lighting connection, which was determined by the architectural design department after careful calculation of the design scheme of Huigu Sunshine. The light from the south lighting surface and the north light receiving surface can be effectively connected to ensure adequate lighting and ventilation in the room. The indoor depth is short, and the indoor space is affected by factors such as pipelines and spatial layout, which may be the kitchen and bathroom. Both the kitchen and the bathroom have lighting surfaces, which are beneficial to daily lampblack, bathroom moisture, odor and so on. Can be discharged outdoors through natural ventilation, which can not only effectively keep the room clean, but also be beneficial to health. This pure board architectural design not only improves the health and comfort of the house, but also greatly improves the utilization rate, reaching 83%.

In addition to the signboard with small depth, wide area and transparent north and south, Ms. Chen Nanping, director of Kyoto real estate marketing planning, believes that the real banlou is a residential product that can meet people's pursuit of higher quality of life. There are very strict requirements in orientation, permeability, building density and per capita greening rate. Although some products are transparent, they cannot meet the requirements of lighting in the north because of the east-west direction, so they are not real board buildings; Some products are built too high, which increases the floor area ratio and reduces the per capita possession of green space. They are not real banlou. Therefore, when Kyoto Real Estate Company developed Fu Gui Garden, although it was located in the East Second Ring Road, in order to ensure the living quality of the banlou community, the whole community was all nine-story banlou with one staircase and two households, with a plot ratio of only 2.3 and a greening rate as high as 40%. Such a design with low floor area ratio and high greening rate is more conducive to giving full play to the advantages of ventilation and lighting of the board building, and at the same time making the indoor apartment more square. The 88-square-meter two rooms, two halls and one bathroom are not only conducive to ventilation and lighting, but also conducive to dynamic and static partitions, clean partitions, dry and wet partitions, and the functions of life, leisure and catering are reasonably and comfortably distributed. The master bedroom and living room facing south provide great convenience for the host's life.

Therefore, experts remind property buyers that when buying a house, they must have the awareness of identifying the authenticity of the banlou. Don't think that as long as the building shape conforms to the ratio of length, width and height, it must have good ventilation and lighting characteristics of the board building. We should study the internal structure of the house. Only when the width and depth of the apartment are in a proper proportion, and the plot ratio and greening rate of the residential area reach a certain standard, can the characteristics of good ventilation and lighting of the board building be achieved.
