Orionis Planetarium and Observatory / Snøhetta

由专筑网小R编译

该项目的地点十分引人注目，旁侧有着Scarpe河、Arkéos考古博物馆，还有一些住宅，建筑师需要将这些元素和谐地连接在一起，为使用者打造出流畅且积极向上的空间，Snøhetta事务所设计了一座统一的建筑，曲线环绕着投影室和天文台的两个穹顶。

Situated on a remarkable site, between the adjacent Scarpe river, the archaeological museum Arkéos and a nearby residential complex, the project aims to harmoniously connect these elements and create an accessible and inspiring space for visitors. Snøhetta’s design is a unified building with curves that wrap around the two domes of the projection room and the observatory.





在该项目中，Snøhetta事务所与CET Ingénierie、Impact Conseil et Ingénierie、Cicanord、Studio Dap ，以及Atelier Silva Landscaping等工作室展开密切合作，从2019年起便投身该项目之中，见证了建筑的诞生，这座建筑也与今年5月13日面向公众开放。

In close collaboration with CET Ingénierie, Impact Conseil et Ingénierie, Cicanord, Studio Dap and Atelier Silva Landscaping, Snøhetta has been working on the building since late 2019, seeing the project through from concept to construction. Orionis opened to the public on the 13th of May 2023.







椭圆——永恒且流畅的概念

Snøhetta事务所的联合创始人Kjetil Trædal Thorsen说：“我们希望为使用者带来特别的聚会场所和全新的目的地，该项目的概念来源于行星的椭圆形运动轨迹，我们重新诠释了流畅的永恒理念，这不仅体现于形态之中，更是表达在人们的体验里。”

Ellipse - a timeless and fluid concept
​“We wanted to propose an extraordinary meeting place and a new destination for the inhabitants of Douai. The architectural and urban concept of our project takes its inspiration from the elliptical movement of the stars. Being continuous, fluid and perpetual are notions that we have reinterpreted in the project, not only in terms of the shape but also in the experience that visitors will have of the planetarium, all senses employed” explains Kjetil Trædal Thorsen, co-founder of Snøhetta. ​​



项目的灵感来源于连续的运动概念，从而定义了接待区、展览区、圆形剧场，以及建筑的穹顶，这座建筑通过斜坡连接，人们通过透明的立面可以看到内部。

The concept of continuous movement has inspired the project throughout, defining everything from the reception area, the exhibition spaces, the amphitheater, and the domes of the building. The building is linked by a slightly inclined ramp, visible from the outside through the building’s partly translucent façade.



当地环境的整合

​永恒的理念存在于Scarpe河和周围景观的不断变化中，它们和天文馆都形成了物理与视觉上的联系，设计方案的目的是和建筑无缝融合在一起，共享景观区域和停车场，连接两个建筑体量。

两个穹顶的目标是成为视觉焦点，在不影响人们生活的前提下，成为当地的视觉标志，建筑师的目标是通过其形态来表达内部的功能。

Integrated into the local environment
​The notion of timelessness is also found in the continuous movement of the Scarpe river and the surrounding landscape that weaves a physical and visual link to the planetarium. It is designed to integrate seamlessly with the Arkéos Museum and shares landscaped areas and parking lots intended to connect these two cultural entities. ​
​The two domes aim to be a visual signal that can be seen from afar while not impacting the local neighborhood. Snøhetta’s goal was to reveal the building’s program and function from the exterior through its shapes.



将景观和周边环境连接在一起

室外空间的设计有两个显著特征，即周边景观和椭圆形内部院落，它们都能够很好地利用场地特色，同时结合周边景观环境，打造有序的文化场景。

Linking landscape to its surroundings ​
The design of the outdoor spaces has two distinct characters; the surrounding landscape and an elliptical interior courtyard. Both help to create a coherent and contextualized cultural destination that takes advantage of the outstanding features of the site while integrating seamlessly with the surrounding landscape.



景观设计促进了场地的生物多样性特征，整合了现场材料，花园里的天然石材道路连接了建筑和室外空间，构成了特殊的肌理感，除此之外，经过设计的绿色植物更加完美地将停车区域和院落整合在一起。

​屋面种植有绿化，构成了有机的自然视觉要素，突出建筑内部的视觉感受。

人们进入建筑之后便能够看到绿色植物和室外露台空间，和外部自然景观构成视觉上的联系。

The landscape is designed to promote biodiversity and integrates the materials present on the site. The garden has a continuous pathway that connects various outdoor spaces and the building. The path is paved with natural bluestone from Belgium, providing an additional layer of texture and visual expression. Also, plants and trees are strategically placed to integrate the parking spaces and the forecourt.​​
​The roof is planted with wild grass, creating a natural and organic visual element that is highly visible inside the building. ​
Once inside the building, the planted and glazed patio is visible from all interior spaces and works as a calm outdoor space, providing a connection to the natural landscape outside.​​



使用者是该项目的核心

这座建筑的设计满足了使用者的诸多需求，同时和天文馆的整体主题保持统一性。​

游客流线连贯清晰，从礼品店到展览空间，再来到沉浸式展厅，接着，坡道将游客带回到地面层的出口方向。

Users at the heart of the project ​
​The design of the building addresses the needs of the many users maintaining a sense of coherence and continuity with the overall theme of the planetarium.
The visitor circuit flows smoothly from the entrance, through the gift shop and exhibition space, all the way to the immersive room. Then, the ramp gently brings the audience back down to the ground floor and towards the exit. ​





诸如一层观测区域和办公区域等特定用房有着特定通道，流线不会交叉。


材质是关键要素

天文馆的外立面灵感来自于周边建筑所使用的材料，比如Arkéos博物馆和砖石住宅，建筑主要由三种色彩构成，即杨树的木色调、钢遮阳篷的铁锈色，还有投影室穹顶的浅灰色PVC膜。

Specific areas have dedicated access to ensure that the flows do not intersect, such as the observatory area and offices on the first floor.

Materiality a key element
The planetarium's exterior envelope is inspired by the surrounding region and the materials used in nearby buildings such as the Arkéos Museum and brick houses. The project is composed of three main colors: the evolving wood color of the poplar, the rust color of the steel brise-soleils, and the light gray PVC membrane that covers the dome of the projection room.







主要立面幕墙前侧的钢板和侧面木板的色彩灵感都来源于Arkéos博物馆，很好地构成了环境凝聚力。

周边区域低楼层的屋面绿植繁茂，自然元素丰富，让建筑和场地景观更好地融合在一起，演播厅穹顶覆盖着浅灰色PVC膜，削弱了视觉冲击，强调了环绕着立面的路径。

The color of the steel panels in front of the curtain walls on the main façade and wood siding, both inspired by the Arkéos Museum, contribute to a cohesive design that blends with the environment.
The roof of the lower level near the neighboring parcels is vegetated, adding a natural element that helps integrate the project into the existing site landscape. The screening room dome is covered with a light gray PVC membrane, reducing its visual impact and enhancing the path of the ramp that winds around the façade.



可持续发展目标

可持续目标在该项目中起到了重要作用，展厅的地面供暖来源于地热能源，这在冬季可以为建筑供暖，在夏季可以为建筑降温，除此之外，多个开口上也安装有传感设备，做到了智能化自然通风，最后，遮阳篷和绿色屋面能够很好地调节建筑温度和雨水的存储，建筑师首选当地材料，减少碳足迹，也削弱了建筑施工对产生的影响。

Sustainability ambitions
Sustainability played an important role in the design of the project. The heating for the showroom's floor is supplied by geothermal energy, and it provides heating for the building during the winter and cooling during the summer. Additionally, sensors are installed on multiple openings to allow for intelligent natural ventilation. Finally, the sunshades and the green roof also contribute to a responsible regulation of the building's temperature and rainwater. Locally sourced materials were preferred to limit the carbon footprint and allow for a low environmental impact construction site.
