Vincent Callebaut Architectures Reveals Tribute to Notre-Dame with Rooftop Farm

在大火严重破坏巴黎圣母院之后，Vincent Callebaut建筑事务所公布了他们向巴黎圣母院致敬的方案效果图。这是一个超现实项目，象征着富有弹性和生态的未来，项目的灵感来自仿生学和人类与自然之间的公平共生关系。

Vincent Callebaut Architectures has unveiled images of their tribute to Notre-Dame Cathedral following the fire that badly damaged the historic structure. A transcendent project that forms a symbol of a resilient and ecological future, the project is inspired by biomimicry and a common ethic for a fairer symbiotic relationship between humans and nature.



Palingenesis项目源于希腊语中的“重生”和“再生”，旨在使其自然地融合在屋顶和尖顶之间。10米高的阁楼的原始几何形状得到了尊重，从四座山墙开始，沿着55度斜屋顶逐渐伸展，形成垂直的尖顶。设计方案尊重建筑物对飞拱和内部支柱结构负荷的固有原则，屋顶肋条的四条屋脊线和另外四条线弯曲和谐地连接在一起，朝向天穹，构成参数和光的几何特征。

该方案的橡木框架由交叉层压木梁构成，旨在使用最少的材料来确保低碳，同时为大教堂提供空间透明度。在尖顶上，矗立于瓦砾中的雄鸡成为方案的精神象征，同时也是“精神避雷针”和“信徒的保护者”。

The Palingenesis project, derived from the Greek word for “rebirth” and “regeneration,” aims to blend in naturally as a single stroke between the roof and spire. From the four gables, the original geometry of the 10-meter-high attic has been respected, with 55-degree pitched roofs gradually stretching to shape a vertical spire. Respecting the inherent principles of the building’s structural loads towards the flying buttresses and inner fasciculated pillars, the four roofing lines and four lines of the roof’s ribs bend and join together in harmony towards the sky, producing a parametric and light geometry.
Constructed of cross-laminated timber beams, the scheme’s oak frame seeks to use the minimum amount of material to ensure a low carbon footprint while offering transparency to the cathedral. Atop the spire, the rooster located and found in the rubble will crown the scheme, remaining a “spiritual lightning rod” and “protector of the faithful.



“新建筑的尖顶，就好像是从十字架的交叉处冉冉上升的保护神，让大教堂焕发新生，同时也暗喻了教堂的神秘。在尖顶的保护之下，新生命得以出现。这座建筑再一次吸引着整个世界，同时也传递了世界和平的信息与精神象征。”——Vincent Callebaut建筑事务所

该项目的核心是将巴黎圣母院改造为积极的能源建筑，产生的能量多于其消耗的能量。通过与历史纪念碑式的主体的积极联系，现代三维哥特式彩色玻璃的使用能够产生建筑所需的能量，同时也能满足被动式通风需求。

木框架由三维水晶玻璃覆盖，细分为切面菱形元素。这种碳、氢、氮和氧的混合物由有机活性层组成，能够吸收光线并将其转化为能量。存储在氢燃料电池内的能量将直接应用在整座大教堂中。

“The new architecture of the spire, like a shroud raised from the keystone of the transept crossing, evokes the rebirth but also the mystery of the cathedral and the resurrection of Christ. And under the shroud, life and renewal emerge. Notre-Dame dazzles the world again while amplifying her universal message of peace and her spiritual aspiration.”

Central to Callebaut scheme is the idea of turning Notre-Dame into a positive energy building, producing more energy than it consumes. Through energetic solidarity with the body of the historic monument, the contemporary, three-dimensional Gothic stained glass graft produces the scheme’s energy, heat, and passive ventilation.
The wooden frame is covered in three-dimensional crystal glass subdivided into faceted diamond-shaped elements. Consisting of an organic active layer, this cocktail of carbon, hydrogen, nitrogen, and oxygen will absorb light and transform it into power. The energy, stored within hydrogen fuel cells, will be directly redistributed throughout the cathedral.



大教堂阁楼的屋顶尖顶还构成热缓冲空间，冬季积聚热空气，维持室内温度，在夏季通过植物的蒸发蒸腾促进通风。因此，大教堂将成为典型的生态结构工程，是倡导环境修复的真正先驱。

该项目的中心是专门用于沉思和冥想的花园。这不仅满足美学需求，花园由志愿者和慈善协会共同维护。新型复合耕作体系每年每平方米可生产25公斤水果和蔬菜。因此，每年可以收获多达21吨的水果和蔬菜，并直接免费分配给有需要的人们。为此，巴黎圣母院的前院每周都会举办农贸市场。

这座城市农场位于屋顶拉丁十字顶部，设置在种植园内，建筑师基本上重新绘制了地面上六部分拱顶的布局。这座几何花园依赖于双层结构和轻质土壤，沿着教堂中殿，从东到西，从两个塔到后殿种植水果和蔬菜。在南北轴线上，建筑两翼的屋面是水生动物区，这样可以用天然的鱼肥为植物提供食物。此外，这些水上镜面能够反射北侧和南侧山墙上的玫瑰窗，从而增强空间感。

The roof-spire in the cathedral attic also provides a thermal buffer space, which accumulates hot air in winter to better isolate the cathedral, and vents with fresh air in the summer through the evapotranspiration of plants. Thus, the cathedral would become an exemplary eco-engineering structure and the Church a true pioneer in environmental resiliency.
At its heart, the project features a garden devoted to contemplation and meditation. Going beyond aesthetics, the garden is to be cultivated by volunteers and charitable associations. Aquaponics and permaculture produce up to 25kg of fruit and vegetables per square meter per year. Therefore, up to 21 tons of fruits and vegetables could be harvested and directly redistributed for free each year. To that end, a farmers' market would be held every week on the forecourt of Notre-Dame.
This urban farm is arranged atop the Latin-cross plan of the roof and set in planters, which essentially redraw the layout of six-part vaults on the ground. This geometric garden "à la française" relies on a double-deck structure with light soil to grow its fruits and vegetables along the nave, from East to West, from the two towers to the apse. In the North-South axis, the roofs of the transept host aquaponic basins feeding plants with natural, fish fertilizers. Moreover, these water mirrors expand the place by reflecting the rose windows on the North and South side gables.
