华夏文化展示中心位于中国甘肃省兰州市，整个项目分为展演部分与展示部分，展演部分为日月馆，展示部分为古镇展示区，建筑形式与周边兰州传统村落相呼应。项目南临河口古镇与黄河，东临黄河支流——庄浪河，北侧是一片黄土山脉，西侧为兰州区域传统村落，周边自然景观丰富，设计既兼顾周边人文地理，又兼顾了自然风光。同时，兰州曾经做为依托交通干线的“茶马互市”和交易中心，曾经做为不同历史时期的国家基地和区域中心，民族和文化的融汇区和多发地，物质与非物质并行的新文化成长沃土。
Chinese Culture Exhibition Center is located in Lanzhou City, Gansu Province, China. The whole project is divided into show part and exhibition part. The show part is The Sun and Moon Pavilion, and the exhibition part is The Exhibition Area Entrance with ancient town style. The architectural form corresponds to the surrounding traditional villages in Lanzhou. The project is adjacent to Hekou Ancient Town and the Yellow River in the south, Zhuanglang River, a tributary of the Yellow River in the East, the Loess Mountains in the north, and traditional villages in Lanzhou area in the west, with rich surrounding natural landscape. The design not only takes into account the surrounding human geography, but also the natural scenery.At the same time, Lanzhou used to be the “Tea Horse Trade” and trading center relying on the arterial traffic, the national base and regional center in different historical periods, the fusion area and place of nationality and culture, and the fertile land for the growth of new culture with both material and non-material culture.

建筑体量巨大、新颖，建筑由两片巨型屋顶拼接而成，分别覆盖舞台与看台两大部分，并在屋顶上形成“天眼”，形成框景，便于观众观看激光秀与远处山脉，打造成为兰州区域地标建筑。建筑造型围绕舞台与看台展开，将建筑分为舞台与看台两个部分，分别以巨型拱形屋顶覆盖，屋顶表皮经过反复修改，采用外包金属板形式，由于项目邻近中国传统古镇， 剧场外部造型吸收了当地传统建筑的元素，传统村落层层叠叠的屋顶排列（如⻄固河口古镇）。外屋⾯面板如巨鸟的⽻翼一般，具有韵律地自上而下覆盖叠加。屋⾯饰板采用与瓦片有类似质感的材料。其他建筑部分的饰⾯材料采用砖石，⽊材，夯⼟等当地传统材料，使剧场能够充分融入到当地自然⼈文环境中。
The building volume is huge and novel. It is composed of two giant roofs, covering two parts of the stage and the stands. An “eye” on the roof and framed scenery are formed, which facilitates the audience to watch the laser show and the distant mountains, making it a landmark building in Lanzhou.The building shape centers on the stage and stands, with the building divided into two parts of the stage and the stands, which are covered by a huge arched roof respectively. The roof surface adopts the metal plate cladding, which has been repeatedly modified. As the project is adjacent to the traditional ancient town of China,The exterior shape of the theater integrates the elements of the local traditional buildings, with the roof arrangement of the traditional village layer upon layer, just like Xigu Hekou Ancient Town. The outer roof claddings are like the wings of a giant bird, covering and overlaying from top to bottom with rhyme. The materials with similar texture as the tiles are adopted for the roof decorative panels. The local traditional materials such as bricks, woods, rammed earth, etc., are adopted for the finishing surface of other parts of the building, fully making the building fit in the local natural and cultural environment.

The roof is a complicated grid structure, with projection equipment and maintenance catwalk set inside the structure. The roof structure is modeled by Revit, and finally achieves the existing effect, which has a great challenge in the architectural technology.The stage roof and the stands roof are like two wings embracing each other, which correspond to the stage and the stands respectively, creating an immersive performance atmosphere around the theater. The stage roof is a technical roof, which contains various multimedia special effects equipment, catwalks and pipes. The interior finishing surface should meet the requirements of video projection medium. The show pool is a mirror overflow pool, the water level should be the same height as the ground of the first row of the audience area, and the retention pool is right under the show pool.

Roof inner cladding: each geometric panel on the inner cladding forms a complete surface, and the main arch moves along the track of the curve arc on the symmetry axis. Main direction A is parallel to the front arcs of the roofs of the stage and audience area respectively, and its radius curvature is measured. The roof above the audience area has a side arc of 35.95 m and a central arc of 67.78 m. The roof above the stage has a single circular arc with a radius of 41.90 m. Main direction B is parallel to the symmetry axes of the roofs of the stage and audience area respectively, and its radius curvature which is used to form the geometry shape of the inner cladding is measured. The roof above the audience area has a constant radius of 50.4m. For the roof above the stage, the length of the upper arc and the lower arc are 46.25m and 24.33m respectively. By using this method, the inner claddings of the stands roof and the stage roof have their own dimensions. All inner cladding panels are double-curved panels. Because of the same size of the panels, the economic mold construction and manufacturing can be carried out. Roof inner cladding: material composition of cladding panel. The inner cladding surface must have the following properties: excellent sound absorption ability, which can filter out the noise generated by the audience, matte surface, which can enhance the video projection effect. In order to meet the above technical requirements, the common material composition of the inner cladding surface is as follows, from the top layer to the top layer respectively: Roof of audience area: the perforated percentage is about 50%, the round hole with a diameter of about 6mm is opened, with a triangular offset layout. Stage roof: the perforated percentage is about 20%, the round hole with a diameter of about 6mm is opened, with a triangular offset layout.

屋顶设计中，要解决众多问题，包括设备安装、马道安装、成本控制及结构坚固性等，马道上技术人员搬运重型设备时也应正常通行。活动过程中不应含任何障碍物。马道地面设计应尽可能平滑，应为通往屋顶设备的便捷及安全通道（平台不应距离设备太远，太低或太高也不可行），马道应符合安全标准（容量500KG/M2，两侧含扶手）等要求，因此屋顶内部空间复杂，外包装饰铝板，将众多设备与马道隐藏在其中，形成厚重的屋顶的感觉，同时兼顾天眼的视觉效果，难度较大。
In the roof design, many problems should be solved, including equipment installation, catwalk installation, cost control and structural sturdiness. The technicians on the catwalk should also pass normally when carrying heavy equipment. There should be no obstacles during the activity. The design of the catwalk ground should be as smooth as possible, which should be a convenient and safe access to the roof equipment (the platform should not be too far away from the equipment, too low or too high is not feasible). The catwalk should meet the requirements of the safety standard (capacity of 500kg / m2, both sides with handrails). Therefore, the internal space of the roof is complicated, with decorative aluminum panels on the surface. Lots of equipment and catwalks are hidden in it, forming a feeling of a heavy roof. It is very difficult as well to give consideration to the visual effect of the eye simultaneously.

The Sun and Moon Pavilion presents a magnificent visual effect. Centering on the theme of Pan Gu creating heaven and earth, the show presents a deepening legend with Chinese characteristics, applying modern scientific and technological means such as audio, video, laser, animation, geyser, flame, fireworks and artistic forms to form integrating science and technology, culture, art and creativity to give the audience a shocking audio-visual feast.

演出技术方面，在演出中融入激光、火焰、烟花等形式，利用深埋水中、悬挂于屋顶的舞台设备，形成丰富的舞台效果，设备技术先进，可长时间浸泡于水中；位于舞台、看台周边以及场馆外部的众多机房共同为演出提供技术支持。水池和舞台上方的开洞保证水效光效烟花等的正常运转，同时通过洞口，观众有可能窥见群山，建立了与场地的联系，增强了趣味，这是设计的初衷。
In terms of performance technology, laser, flame, fireworks and other forms are integrated into performance, and the stage equipment that is deeply buried in the water and suspended on the roof is used to form a rich stage effect. The equipment technology is advanced and can be immersed in the water for a long time. Numerous machine rooms located around the stage, stands and outside the venue jointly provide technical support for the performance .The openings above the pool and stage ensure the normal operation of water effect, light effect and fireworks. At the same time, it is possible for the audience to see the mountains through the openings, establishing a connection with the venue and increasing the interest, which is the original intention of the design.

在项目的设计过程中，采用BIM技术不断推进，推敲建筑体量、材料与空间之间的关系，同时解决技术层面的问题，为了观众不不受低温、风沙的影响，要求观众席要有屋顶。事实上多媒体设备和演出本身也需要适度的保护，将天气因素和周边公路的噪声和光污染的影响降到最低。因为舞台的上方也是有顶的——“天”，将舞台屋顶和观众屋顶连接起来，将整个演出区域围合成一个半封闭的结构成为一个自然而然的选择。这种围合结构同时可以提供大面积的投影面积，观众将获得更加身临其境，更加丰富的观赏体验。
In the design process of the project, BIM technology is used to continuously promote the relationship between the building volume, materials and space, and solve the technical problems at the same time. In order to protect the audience from the impact of low temperature and blown sand, the audience area must be equipped with a roof. In fact, multimedia equipment and show also need moderate protection to minimize the impact of weather factors and noise and light pollution caused by surrounding roads. Because the top of the stage also has a roof – “heaven”, it is a natural choice to connect the stage roof and the audience roof for making the whole show area into a semi-closed structure. The enclosed structure can provide a large area of projection area at the same time, enabling the audience to get more immersive and rich viewing experience.

在整个设计过程中，不断推敲建筑造型与设备要求之间的关系，由于日月馆的特殊性，存在大量的设备机房及设备空间，建筑利用舞台下面空间、舞台后面空间、看台下空间及屋顶空间合理布置机房与设备，将直接观影设备设置于水池中以及屋顶吊顶内，弱化观众可见度，室内屋顶采用光洁度较高的铝板，最大化减少由于设备造成的视觉干扰。
本方案将传说幻化成纯粹致简的舞台空间，每一个空间元素都饱含象征意义。舞台空间“宽而空阔”，有如宇宙之初；两个斜面相接，有如天地；“天”上有一个圆形的开口，象征太阳和月亮，也呼应中国古代天圆地方的说法。“天地”舞台与观众之间的水池为多媒体设备提供了了必要条件，同时象征着”海洋与湖泊“。通过多媒体投影等技术⼿手段，各种人物动物和神的形象都可以投射在水帘上。
In the whole design process, the relationship between building shape and equipment requirements is constantly studied elaborately. Due to the particularity of the Sun and Moon Pavilion there are a large number of equipment rooms and equipment spaces. The building utilizes the space under the stage, the space behind the stage, the space under the stands and the space on the roof to reasonably arrange the machine rooms and equipment, and directly set the projection equipment in the pool and the ceiling of the roof to weaken the audience visibility. The indoor roof adopts aluminum panels with high finish to minimize the visual interference caused by the equipment.
The project magically transforms the legend into a pure and simple stage space, and each space element is full of symbolic significance. The stage space is “wide and spacious”, just like the beginning of the universe. Two inclined planes join each other, just like the heaven and earth. There is a circular opening in the “sky”, which symbolizes the sun and the moon, and also echoes the ancient Chinese saying of the round heaven and the square earth. The pool between the “Heaven and Earth” stage and the audience provides the necessary conditions for the multimedia equipment, which symbolizes the “ocean and lake” meanwhile. By means of multimedia projection and other technologies, the images of various characters, animals and divinities can be projected on the water curtain.
