布莱加-公共屋顶公园

布莱加-公共屋顶公园
Bryga – Public Rooftop Park

Bryga是一个公共屋顶公园，位于卡拉萨塔马赫尔辛基购物中心Redi的屋顶上。卡拉萨塔马是一个新的快速发展的住宅区，建于赫尔辛基内城东海岸的一个前工业港。Redi是芬兰规模特别大的建筑群，它为卡拉萨塔马地区创造了一个新的城市节点。Redi由购物中心、一个地下停车场和八座30层以上的塔楼组成。其中两座塔目前已建成。在赫尔辛基以东，一条地铁线路和一条高速公路贯穿整个建筑群。
Bryga is a public rooftop park located on the roof of the shopping centre Redi in Kalasatama Helsinki. Kalasatama is a new rapidly growing residential area build on a former industrial harbour in the east coast of the inner city of Helsinki. Redi is a particularly large building complex in the scale of Finland and it creates a new urban node to the area of Kalasatama. Redi consists of the shopping centre, an underground parking and eight over 30-floor height towers. Two of the towers are currently realized. Through the complex runs a metro line and a highway connection to the east of Helsinki.

布莱加公园和四座高层建筑的庭院一起形成了一个异常广阔的室外空间，面积近1.4公顷，所有这些都建在屋顶结构之上。布莱加本身的面积为0.7公顷。在不久的将来，这些庭院将与高层建筑一起建成。公园和庭院构成了雷迪的第五个立面。
Bryga park forms together with four courtyards of the high-rise buildings an exceptionally vast outdoor space, nearly 1,4 hectares, all which is built on top of roof structures. Bryga by itself is 0,7 hectares. The courtyards will be realized alongside the high-rise buildings in the near future. Park together with the courtyards form the fifth façade of Redi.

Bryga – Public Rooftop Park

Bryga as part of Kalasatamas outdoor spaces

布莱加是卡拉萨塔马公共户外空间的重要组成部分。加上卡拉萨塔马公园和英国广场，他们形成了一个由Maanlumo设计的一致的景观建筑概念，为新区创造了一个可识别的标识。室外空间的主题反映了卡拉萨塔马的历史，最初是一个群岛，后来是一个工业港口。
Bryga is an important part of the public outdoor spaces of Kalasatama. Together with Kalasatama park and English square they form a unanimous landscape architectural concept designed by Maanlumo that creates a recognizable identity to the new area. The main theme of the outdoor spaces reflects the history of Kalasatama first as an archipelago and later as an industrial harbour.

布里加的概念基于赫尔辛基群岛的景观和自然，雷迪的建筑被视为一个岛屿。想象中的海水在岩石和植被之间流过公园，塑造了地形，形成了布莱加蜿蜒的小径。材料、植被和结构遵循相同的主题，突出了公园的形状和空间。
The concept of Bryga is based on the landscape and nature of Helsinki archipelago and the building of Redi is seen as an island. The imaginary sea water flows through the park between the rocks and vegetation shaping the terrain and creating the meandering pathways of Bryga. The materials, vegetation and structures follow the same theme highlighting the shapes and spaces of the park.

Terrain, vegetation and stormwater management

小径蜿蜒穿过自然形成的植被小丘。操场和休息区位于土堆之间。所有表面和道路的设计应确保雨水自然流入植被区。主干道旁边是一条雨水通道，收集地表多余的水，作为公园的防洪路线。
The pathways meander through the naturally shaped small mounds of vegetation. The playground and resting areas are located between the mounds. All the surfaces and paths are designed so that the rainwater runs naturally to the vegetation areas. Next to the main route is a stormwater channel that collects the excess water from the surfaces and works as the flood route of the park.

公园位于屋顶，位置极具挑战性，雨水管理和生态可持续解决方案成为设计的主要部分。35%的公园表面是植被，18%是其他透水材料。植被表面增加了城市自然的多样性，改善了小气候、声学和风力条件。公园里有50多种不同种类的植物，如针叶树、多年生植物和各种各样的草，它们代表了群岛的主题。这些植物忍受着屋顶上恶劣的气候条件：不断变化的湿度和强风。整个屋顶的表面下有一个排水和储水元件，用于为植物保留水分并平衡湿度条件。
The challenging location of the park on the roof made stormwater management and ecologically sustainable solutions major part of the design. 35 percent of the park surface is vegetation and 18 percent other water permeable materials. The vegetation surfaces add to the diversity of urban nature and improve the microclimate, acoustics and the wind conditions. The park has over 50 different species of plants that represent the theme of the archipelago, like conifers, perennials and different kinds of grasses. The plants endure the difficult climate circumstances on the roof: changing conditions of humidity and strong winds. The entire roof has a drainage and water storage element under the surface that detains the water for the plants and balances the humidity conditions.

Art Pergolas

11个4.2米高的钢结构凉棚依循公园的主要形状，让人想起了卡拉萨塔马以前的工业和渔业港口。藤架结构在高耸的塔楼旁创造了一个人类的规模。凉棚垂直和水平表面上的钢网为攀援植物的生长提供了基础，同时也提供了防风保护。公园的所有电气基础设施和灯光都集成在凉棚结构和艺术照明中。带有led灯的照明矩阵附着在水平钢网上。艺术照明跟随当地风的运动，从一个凉棚平静地移动到另一个凉棚，创造出一种缓慢的波浪状运动。
The eleven 4,2-meter-high steel structure pergolas that follow the main shapes of the park are reminiscences of the former industrial and fishing harbour of Kalasatama. The pergola structures create a human scale next to the high-rise towers. The steel meshes on the vertical and horizontal surfaces of the pergolas provide a base for the climber plants to grow on and they also provide protection from the wind. All the electrical infrastructure and lights of the park are integrated in the pergola structures as well as art lighting. Lighting matrixes with led lights are attached on the horizontal steel meshes. The art lighting follows the movement of the local wind and it moves calmly from one pergola to another creating a slow wave-like movement.

Functions

公园白天开放。你可以从购物中心乘电梯进入公园。外面有一个从英国广场连接的楼梯和一个从朱纳蒂街连接的自行车和人行坡道。Bryga有多个函数的空间。公园东侧有一个小型活动广场，可以举办弹出式活动、户外画廊等。公园中心有一个操场，为不同年龄段的人提供活动。布莱加周围有很多休息和野餐的地方。从公园的西端，你可以欣赏到公园和赫尔辛基天际线的远景。
The park is open during the daytime. You can access the park from the shopping centre with an elevator. Outside there is a stair connection from the English square and a bike and pedestrian ramp from the Junatie street. Bryga has spaces for multiple functions. In the east side of the park there is a small event square that can host pop-up events, outdoor galleries etc. In the centre of the park there is a playground that provides activities to different age groups. Around Bryga there are multiple places for resting and picnic. From the west end of the park you can enjoy long views to the park and to the skyline of Helsinki.

Visionary design

Bryga代表了未来的设计解决方案，城市的所有区域都被认为是有价值的，设计过程是多学科的。公园为周围环境增添了生态和视觉价值，否则会被认为是非常技术性的，甚至是充满敌意的。在高层建筑旁边，公园提供了人性化的规模，公园的自然形状缓和了恶劣的环境。布莱加丰富了当地环境，为城市文化的发展提供了场所。它结合了建筑、景观设计、照明设计、艺术和生态解决方案。
Bryga represents future design solutions where all areas of the city are considered valuable and design process is multidisciplinary. The park adds an ecological and visual value to the surroundings that otherwise would be considered very technical and even hostile. Next to the high-rise buildings the park provides a human scale and the natural shapes of the park softens the hard environment. Bryga enriches the local environment and provides a place for urban culture to grow. It combines architecture, landscape architecture, lighting design, art and ecological solutions.
