椭圆形建筑：天文馆和天文台

该项目坐落在一个非凡的地块上，毗邻Scarpe河、Arkéos考古博物馆和附近的住宅区，旨在将这些元素和谐地连接在一起，为游客创造一个无障碍的、鼓舞人心的空间。斯诺赫塔的设计是一个统一的建筑，曲线环绕着放映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. Sn?hetta’s design is a unified building with curves that wrap around the two domes of the projection room and the observatory.

Sn?hetta与CET Ingénierie、Impact Conseil et Ingénierie、Cicanord、Studio Dap和Atelier Silva Landscaping紧密合作，自2019年下半年以来一直致力于该建筑的设计，见证了项目从概念到施工的全过程。Orionis于2023年5月13日向公众开放。

In close collaboration with CET Ingénierie, Impact Conseil et Ingénierie, Cicanord, Studio Dap and Atelier Silva Landscaping, Sn?hetta 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.

椭圆形 - 永恒而流畅的概念

我们希望为杜埃的居民提供一个非凡的聚会场所和新的目的地。我们项目的建筑和城市理念从恒星的椭圆运动中汲取灵感。Sn?hetta的联合创始人Kjetil Tr?dal Thorsen解释说：连续、流动和永恒是我们在项目中重新诠释的概念，这不仅体现在外形上，还体现在参观者对天文馆的体验上，所有的感官都被调动起来。

“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 Tr?dal Thorsen, co-founder of Sn?hetta.

连续运动的概念贯穿了整个项目，从接待区、展览空间、露天剧场到建筑的穹顶，无不如此。建筑之间通过一个略微倾斜的坡道相连，从建筑半透明的外立面向外可以看到坡道。

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 facade.

融入当地环境

永恒的概念还体现在Scarpe河和周围景观的持续运动中，这些景观与天文馆形成了物理和视觉上的联系。天文馆的设计与Arkéos博物馆天衣无缝地融为一体，并共享景观区和停车场，旨在将这两个文化实体连接起来。

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.

这两个穹顶旨在成为一个视觉信号，可以从远处看到，同时不影响当地的邻里关系。Sn?hetta的目标是通过建筑的外形从外观上揭示建筑的项目和功能。

The two domes aim to be a visual signal that can be seen from afar while not impacting the local neighborhood. Sn?hetta’s goal was to reveal the building’s program and function from the exterior through its shapes.

将景观与周围环境联系起来

室外空间的设计有两个不同的特点：周围的景观和一个椭圆形的内部庭院。两者都有助于创造一个连贯的、情景交融的文化目的地，既利用了场地的突出特点，又与周围景观完美融合。

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.

景观的设计旨在促进生物多样性，并与场地内的材料融为一体。花园里有一条连续的小路，将各个室外空间和建筑连接起来。小路由比利时的天然青石铺成，增加了质感和视觉表现力。此外，还战略性地种植了植物和树木，使停车位和前院融为一体。

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.

屋顶种植了野草，创造了自然有机的视觉元素，在建筑内部非常明显。

The roof is planted with wild grass, creating a natural and organic visual element that is highly visible inside the building.

一旦进入建筑，所有内部空间都可以看到种植和玻璃的露台，它作为一个平静的室外空间，提供了与外部自然景观的连接。

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.

用户是项目的核心

建筑的设计满足了许多用户的需求，保持了与天文馆整体主题的连贯性和连续性。

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.

游客线路从入口流畅地流过礼品店和展览空间，一直到沉浸式房间。然后，坡道轻轻地将观众带回到一楼并走向出口。

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.

特定区域有专用通道，以确保流动不会相交，例如一楼的天文台区和办公室。

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

物质性是一个关键因素

天文馆的外部外壳的灵感来自于周围地区和附近建筑中使用的材料，如arksamos博物馆和砖房。该项目由三种主要颜色组成:杨树的演变木色，钢板遮阳板的铁锈色，以及覆盖放映室圆顶的浅灰色PVC膜。

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.

剖面图

主立面幕墙前的钢板和木壁板的颜色都受到了arksamuos博物馆的启发，有助于形成与环境融合的凝聚力设计。

The color of the steel panels in front of the curtain walls on the main facade and wood siding, both inspired by the Arkéos Museum, contribute to a cohesive design that blends with the environment.

靠近邻近地块的低层屋顶被植被覆盖，增加了自然元素，有助于将项目融入现有的场地景观。放映室的穹顶覆盖着浅灰色的PVC膜，减少了它的视觉冲击，并增强了环绕立面的坡道的路径。

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 facade.

可持续发展目标

可持续性在项目设计中发挥了重要作用。展厅地板的供暖是由地热能提供的，它在冬季为建筑提供供暖，在夏季提供制冷。此外，传感器安装在多个开口上，以实现智能自然通风。最后，遮阳篷和绿色屋顶也有助于负责任地调节建筑的温度和雨水。当地采购的材料是首选，以限制碳足迹，并允许一个低环境影响的建筑工地。

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.
