(1) Location: 1. The project is located in Gong Wei Village, Haidian District, Beijing, east of Baiyi Road (Zhongguancun South Street) and north of Diaoyutai, with a planned total land area of 12428 square meters. The two sides of the project are mostly state-level scientific research units, colleges and universities, forming a special connotation of the region. 2. It is adjacent to Baiyi Road (Zhongguancun South Street), the main urban traffic road in the west, and it is1500m away from Zizhuyuan Park; It is adjacent to Peking University Stomatological Hospital in the south and PLA Art College in the east and north. 3. Total construction area of this project: 6.5438+250,000 square meters; Planned uses include: commerce, office buildings and underground garages; The whole project has four floors underground, and the ground is divided into four office buildings, A, B, C and D, of which Building A 10, Building B 16, Building C 19 and Building D have 22 floors. The first, second and third floors on the ground are connected, of which the first and second floors are commercial and the third floor is office building; The basement is for business, and the second, third and fourth floors are for garage, staff canteen, equipment room and other supporting facilities. (2) Surrounding traffic: 1. On the west side of the project is Zhongguancun South Street (Baiyi Road), which is the main urban road connecting the city center and Zhongguancun Science Park. Weigongcun Road on the north side plays an important role in connecting the West Second Ring Road and the Third Ring Road. Xizhimenwai Street on the south side is an important channel connecting the North Third Ring Road, Baiyi Road and Xizhimen transportation hub. 2. Bus lines: 16, 320, 332, 7 16, 7 17, 727, 732, 804, 808, 8 14, 827, 849, 904. 3. Urban rail transit: It is very convenient to take subway lines 2 and 4 and light rail. (3) Internal flow: 1. The pedestrian flow system takes a square square enclosed on three sides as the distribution space, and organizes the pedestrian flow through the vertical transportation system of the square-the entrance hall of the building podium-each building, which is simple, reasonable and rapid to evacuate. At the same time, the square area (33.25m * 33.25m) can meet the needs of inner ring fire engines in emergency. 2. All four floors underground are connected, and all three floors above ground are connected, so as to create a business atmosphere to the maximum extent; There are air corridors on individual floors above five floors, so that the four buildings are independent and connected, and the office structure can be arbitrarily combined. Second, the humanistic environment: it is located in the Art College of the People's Liberation Army, adjacent to Diaoyutai and National Library in the south and Friendship Hotel in the north; State Meteorological Administration, China Academy of Agricultural Sciences, Foreign Experts Bureau and other government agencies are close at hand; There are many famous universities such as Minzu University of China, China Renmin University, Beijing Institute of Technology, Central University of Finance and Economics, Beijing Foreign Studies University, etc. Nearby, and the human environment is superior. Three. Product features: (1) Design concept: The project was planned and designed by German architect Otto Steidle. The whole building is surrounded by four rectangles with the same shape at the bottom. Four rectangular towers are arranged counterclockwise from low to high, and the towers are connected by air corridors, which gives people a strong visual impact and artistic appeal. The overall design is concise, lively, full of the sense of the times and without losing everyone's demeanor, and will become a landmark building in this area.

Fire escape 1 (1050Kg, 1.75 m/s, B4- 10 floor) * passenger escape 1 (1050Kg,1. 1 fire escape (1050Kg, 1.75 m/s, B4-16th floor) Building C: 4 passenger elevators (1350Kg, 2.5m/s, B4-/kloc). 2 fire ladders (1352Kg, 2.5 m/s, B4-19th floor) Building D: 4 passenger elevators (1350Kg, 2.5m/s, B4-22nd floor); 2 fire ladders (1352Kg, 2.5 m/s, B4-22nd floor) * 1 passenger ladder (1050Kg, 1.6 m/s, B4 to the ground floor) * 1 22. The meeting rooms on the ground 1 and the second floor are all-air air conditioning systems. Property and other rooms are split air-conditioned. Cold source: it is a water chiller set in the refrigeration room on the fourth floor underground. Heat source: provides heat for the thermal power station located on the third floor underground. The heat source is municipal heat. Air conditioning fresh air system: provides fresh air for the air conditioning units located in the underground part, the air conditioning units in the conference room on the second floor above ground and the fresh air units on each floor above ground. Roof ventilator sends intake air to each unit through each shaft. Fresh air volume: according to Grade A office standards, the meeting room and office are 30m3/h*p, and the dining room is 20m3/h * p. Power system-power supply system: dual power supply: Zizhuyuan Substation [project dynamics] >> Beijing International Building A is bought and sold by the new building of Zhejiang University, with a sales amount of nearly 22006-10-/kloc.
