海南能源交易大厦傲然屹立于海口市的新兴中央商务地段—江东新区，北临琼州海峡，南侧近江东大道。兖矿能源集团从事采矿生产和销售、煤炭精细加工和现代物流系统，其早期进驻江东新区，可发挥集聚与示范效应，带动世界顶尖企业积极参与海南自由贸易区的开发建设。
The Hainan Energy Trading Building stands proudly in Jiangdong New District, an emerging industrial, financial, and residential development on the outskirts of Haikou, capital of China’s Hainan province. The Yankuang Group, owner and occupier of the building, specializes in mining production and sales, high-end coal processing, and modern logistics, and the early entry of the firm’s headquarters in Jiangdong New District paves the way for other leading business to follow suit.

建筑设计如同漂浮于公园之上的方盒子，尺度宏大、充满绿意的采光中庭让人惊叹，错落有致的空中花园柔化了建筑的刚硬线条，刚与柔在建筑中和谐共存，如同江东新区在既有基地条件限制下发展出尖端技术。
The building is a floating box above a landscaped ground floor, and an impressive central courtyard greets visitors as they enter the atrium. The rigid lines of the exterior contrast with the sky gardens positioned at regular intervals—a blend of rigidity and softness that creates a harmonious whole, mirroring the fledgling district’s aim of combining existing site conditions with cutting-edge technology

呼应兖矿集团打造绿色能源的精神，建筑设计将绿化面积最大化。每四层楼对角线交错配置挑高的空中花园，连接服务核的弧形阳台环绕着中庭。室内阳台和空中花园中孕育多样的植物，狂放的绿意在层层迭迭的阳台与穿透中庭的天光之间流动，营造充满自然气息与平和宁静的工作氛围。
The sustainable design of this project goes hand-in-hand with Yankuang Group’s green-energy initiatives. Firstly, greenery is maximized with the exterior sky gardens as well as abundant planting in the interior. The sky gardens punch in opposing corners in an orderly fashion, occurring every four floors and rotating 90 degrees each time. Inside, multiple tiers of curving balconies span the spaces between the elevator boxes and these are densely packed with unruly plants that spill out over their edges. This is a nature-filled space, designed to provide employees with a sense of peace and well-being.

75米高的中庭连结空中花园与地面层开放空间，形成空气循环的通道，由于每层楼空气的压力、温度和密度不同，引入的新鲜空气将陈旧的空气向上推，经由屋顶开口排出，形成自然通风的循环流动，配合外遮阳系统，创造舒适宜人的微气候。
Secondly, the courtyard creates a pleasant microclimate, made possible by an effective shading and stack ventilation strategies in the 75-meter-high atrium. Due to the differences in air pressure, temperature, and density levels at each floor, incoming fresh air forces stale air upward and out through the roof opening, keeping the interior well ventilated and thermally comfortable for its users.

通透的玻璃帷幕外墙提供绝佳视野，可一览海岸线与城市地景，同时展示了内部利落、纤细、但坚固的结构系统。设计利用巨大的斜撑传递承重，不仅保留空中花园的完整性，不被结构柱干扰，也支撑着花园上方量体约 14 米的悬臂，此做法将结构的侧向挠度降到最低，同时也加强其抗震性。
One particularly spectacular feature is the energy-efficient double skin façade design with high-transparent glass, which from the inside provides office workers with unobstructed views of the coast and downtown area, and from the outside proudly showcases the building’s structure—clean, slender, yet very robust. None of the pillars interrupts the spacious sky gardens that rotate every four levels, allowing the volume of the other four floors above to cantilever up to 14 meters. This is achieved through mega-bracings that minimize the lateral deflection of the structure, and provide a feasible solution for strengthening earthquake resistance.

双层的玻璃帷幕外墙满足了自然采光及节能的需求，降低人工照明及空调的使用。内层采用Low-E玻璃以有效隔热，并藉由双层玻璃间的腔体将辐射热能导出。内外层玻璃之间的电动百叶，可由屋顶追日系统的传感器自动调整，配合智能照明控制系统的设置，大幅增加室内环境的舒适感。此外，斜屋顶和每四层交错的内退提供空中花园和办公室充足的阳光，同时因应海南湿热的气候，避免大部分的走廊和中庭受阳光直射。斜屋顶取自江南的传统建筑元素，下雨时，雨水由屋顶斜面落下，聚集在四方的天井之中，以示「水聚天心、泗水归堂」，有积聚财富的意涵。
Sufficient daylight pours through the double skin facade on all four sides, lowering the need for artificial lighting. The electric louvers between the inner and outer glass layers can be automatically adjusted by the sensors of the solar tracking system, which, together with the intelligent lighting control system, greatly increase the comfort of the indoor environment and reduce the use of air-conditioning system to reach energy-saving goals. In addition, the slanted roof and the offset facade at four-story intervals provide the sky gardens and the office spaces with ample natural light, while shading most of the corridors and atrium to prevent overheating in the warm Hainan climate. The roof also pays tribute to the traditional Jiangnan home, in which rain is designed to run down slanted planes on four sides and gather in a square courtyard below, signifying the flow and retention of good fortune into a family—or in this context, a company.
