項目基地北臨西安北三環高架，巨大的車流量給項目帶來的城市交通噪音是設計必須解決的問題。生態中庭作為辦公空間和城市間的過渡空間有效的改善了辦公空間的物理環境，同時面向城市界面的生態中度的垂直綠化猶如一個巨大的展示櫥窗，向城市展示了廣聯達“綠色建筑 共創美好生活”實踐案例。

The project base is north of Xi 'an North Third Ring Viaduct, so the urban traffic noise brought by the huge traffic flow to the project is a problem that must be solved in the design. As a transitional space between office space and city, ecological atrium effectively improves the physical environment of office space. At the same time, the ecological moderate vertical greening facing the urban interface is like a huge display window, showing the practice case of Guanglianda ' Green building create a better life ' to the city.

本項目采用EBI樓宇自控系統。通過對樓內冷熱源、空調系統的最佳控制，溫、濕度的自動調節，新風量的控制，空氣質量PM2.5、CO?、噪聲，風速、風壓差等的監測，對等自動調節并合理設計從而保證大廈中各個區域和功能滿足環境的要求。為提高辦公人員的社會交往能力，一層中庭設有生態公園，二層以上南面，東面、屋面分別設置有室外露臺和活動場地。人員主要活動場所設置無障礙設施。整個辦公區采用裝配式靈活隔斷，以適應未來不同的功能需求。

This project adopts EBI building automation system. Through the best control of the cold and heat sources and air conditioning system in the building, the automatic adjustment of temperature and humidity, the control of fresh air volume, the monitoring of air quality PM2.5, CO?, noise, wind speed, wind pressure difference, etc., the equivalent automatic adjustment and reasonable design to ensure that the various areas and functions in the building meet the environmental requirements. In order to improve the social interaction ability of office staff, an ecological park is set up in the atrium of the first floor, south of the second floor, and outdoor terraces and activity venues are set up on the east and roof respectively. The main activity venues for personnel are equipped with barrier-free facilities. The entire office area adopts prefabricated flexible partitions to meet different functional requirements in the future.

主要辦公區布置于南側朝向創業園區內部，強調生活空間充足的自然光源，共同營造安靜舒適的辦公環境。公共交流空間則圍繞可開啟天窗的生態中庭布置，內部空間都能體驗到自然光與環境的對話，利用太陽能光導技術改善地下室采光，并結合景觀下沉庭院開設自然通風窗扇。建筑外立面設置綜合外遮陽，寶內設有活動遮陽簾，并結合智能照明控制系統，實現辦公樓室內優良的光環境。

The main office area is arranged on the south side towards the interior of the entrepreneurial park, emphasizing the sufficient natural light source of the living space, and jointly creating a quiet and comfortable office environment. The public communication space is arranged around the ecological atrium that can open the skylight. The internal space can experience the dialogue between natural light and the environment. The solar light guide technology is used to improve the lighting of the basement, and the natural ventilation fan is set up in combination with the landscape sunken courtyard. The external facade of the building is set up with comprehensive external shading, and the active shading curtain is set up inside the building. Combined with the intelligent lighting control system, the excellent light environment in the office building is realized.

本項目體型系數為0.12，通過屋頂綠化，外墻外保溫系統、綜合遮陽措施，高效節能的設備系統，使得供暖、通風與空調系統能耗降低幅度為16.8%。1800㎡通高46m的中庭空間，冬季窗充分利用太陽輻射。夏季則將成部天窗開啟，誘導底部冷氣流上升，使得中庭區域溫度分布更加均勻，可以節省大量制冷能耗。建筑屋頂根據局部設置有光伏板；太陽能光熱板則為健身區淋浴和食堂提供熱水。

The shape coefficient of this project is 0.12. The energy consumption of heating, ventilation and air conditioning system is reduced by 16.8 % through roof greening, external thermal insulation system, comprehensive shading measures and efficient energy-saving equipment system. With 1800㎡of 46m high atrium space, the winter window makes full use of solar radiation. In summer, the sunroof is opened to induce the cold air flow at the bottom to rise, which makes the temperature distribution in the atrium more uniform and saves a lot of refrigeration energy consumption. The building roof is equipped with photovoltaic panels according to the local setting; solar panels provide hot water for showers and canteens in the fitness area.

整個項目室內部分和主體外幕墻圍護結構采用裝配式建造技術，本著資源可循環再利用的原則，所使用材料均符合現行國家有關綠色產品評價標準，場地東北角設置智慧雨水收集池，對屋面、地面匯流雨水進行收集，并通過一系列海綿措施:下沉綠地，透水鋪裝、鏡面水景、海綿花園等措施，用于基地內綠化澆酒場地沖洗、冷卻塔補水、沖廁用水。

The whole project indoor part and the main external curtain wall enclosure structure adopt the prefabricated construction technology. In line with the principle of resource recycling, the materials used are in line with the current national green product evaluation standards. The intelligent rainwater collection pool is set up in the northeast corner of the site to collect the rainwater on the roof and ground, and through a series of sponge measures: sinking green space, permeable pavement, mirror waterscape, sponge garden and other measures, it is used for the green watering site washing, cooling tower water replenishment and toilet flushing in the base.

本項目內嵌的巨大綠色中庭對整個社會開放共享，并通過BIMONE設計協同平臺，數字化集成設計、數字化精益建造、智能化現場管理，最終實現全生命周期綜合效益最大化，打造高性能綠色建筑。

The huge green atrium embedded in this project is open and shared to the whole society, and through the BIMONE design collaborative platform, digital integrated design, digital lean construction, intelligent on-site management, and ultimately maximize the comprehensive benefits of the whole life cycle and create high-performance green buildings.
