(Urgent) Feng Ping Building (20 points)

From the developer's point of view, screen architecture generally refers to several skyscrapers in densely populated cities, which block the light. The screen building is like a screen, and the property design of the roof of Dawei Railway Station and Kowloon Depot belongs to this kind of sealing design.

Wanying Garden can be said to be one of the examples of screen architecture.

cause

Critics believe that the emergence of screen architecture is due to the lack of urban planning and supervision. When developing new areas outside the urban area, real estate developers, in order to make full use of expensive land, on the one hand, develop new buildings into high altitude, on the other hand, try to narrow the space between buildings and form screens, so that the old areas in the urban area are like basins. In China, Tai Wai, Tsuen Wan and Sham Shui Po all face this problem.

In addition, some people think that the appearance of the screen building is related to the relocation of the old Kai Tak Airport, the abolition of height restrictions for buildings in urban areas and the amendment of the Buildings Ordinance, so that there is no need to install windows in toilets, and developers can change the residential design of one staircase and eight groups.

There is also a view that in recent years, * * * has changed its land use practices and merged small streets and lanes into a larger development area, resulting in the same floor area ratio but more building area, and finally the giant screen building appeared.

Concept proposer

The screen effect was first put forward by Changchun Society. In 2004, Changchun Society opposed Hopewell Group's Wan Chai South Hotel project, thinking that the design of hotel buildings, like screens, would affect the air circulation in Wan Chai.

Since 2006, Environmental Touch, an environmental protection group, has launched many actions against the screen building, and put forward judicial review and * * * at the site of land transfer to oppose the auction of the land suspected of building the screen building [1], resulting in the auction price being much lower than that of real estate developers.

affect

Screen effect means that the building is like a canopy, which blocks the entry and exit of natural wind, making the air in the city worse, "dark" and sultry, affecting the living environment, air quality, landscape and natural light of the surrounding residents, weakening the air flow in the relatively inland areas, raising the temperature, aggravating the regional air pollution problem and increasing the proportion of residents suffering from respiratory diseases.

Methods of suppressing screen buildings in different places

In 2003, Shanghai passed the "Shanghai Urban Planning Control Technical Regulations", which stipulated that the maximum continuous width of buildings with a height of more than 60 meters should not exceed 60 meters, and the maximum continuous width of buildings with a height of less than 8 floors should not exceed 80 meters.

When Singapore rebuilt the Singapore River in the190' s, the height limit of steps was set along the river bank, and the Singapore River was divided into three areas as the radiation center. The height of the riverside area shall not exceed 4 stories, the height of the buffer area shall not exceed 10 story, and the height of the peripheral area shall not exceed 35 stories.

Microclimate analysis was adopted in the second and third reconstruction plans of Shangcun Village in Niutoujiao, China, and the needs of sunshine, lighting and ventilation were considered.

With reference to the guidance of the planning guidelines and according to the different needs of each district, the zoning planning outline map is formulated in line with the actual environment of this district, the labeling function of the outline map is strengthened, and the plot ratio within the outline map is strictly planned. One view is that in recent years, we have changed our land use practices and merged small streets and alleys into larger development areas, resulting in more building areas under the condition of unchanged floor area ratio, and eventually a huge screen building will appear. ,
