Osamu Morishita Architect and Associates公布了观海之园（See Sea Park），该项目在由日本福井县大饭町于2019年夏末举办的竞赛中胜出，竣工于2022年。项目主要的需求是建造一个能够促进人们创新并发展新产业的场所。

Osamu Morishita Architect and Associates present See Sea Park, a project selected in a competition held by Ohi-town in the Fukui prefecture, Japan, at the end of Summer 2019 completed in 2022. The main requirement for the proposal was to develop a location where people can innovate and develop new businesses.

在观海之园（See Sea Park），人们能够聚集、消遣或是工作。旧钦州之森（神社周围的森林）的场地一直以来用于夏季节日、新年夜或是其他传统活动庆祝。想法起源于重塑现代化的旧钦州之森。不同于封闭的空间，建筑师设计了一片漂浮于空中，如云朵般水平展开的空间。

See Sea Park is a place where people gather, spend time, and do business. The grounds of the old Chinju-no-Mori (forest surrounding shrines) is used for summer festivals, as well as for New Year’s Eve and other traditional celebrations. The initial idea was to recreate Chinju-no-Mori in modern times. Instead of a closed space, the architects designed a space that unfolds on the ground horizontally below the floating air, like clouds.

这样的设计在秩序中创造了多样性。该项目的目标在于创造一系列聚落般的乡村私人住宅，营造出引人注目的空间组合，给人深刻熟悉的印象。

In doing so, diversity will be created within the order. The aim is to create a kind of place where rural private houses accumulate in a village to create an attractive spatial density with the topography that is an impressive, yet timeless place familiar to the people.

该建筑能够存储太阳能并随时供应所需。还有一个能够控制上层空气的装置，与地球热环境同步。该装置受传统日式住宅启发制造而成。

Buildings absorb and store solar energy and occasionally release heat. In sync with the thermal condition of the earth, there is a unit that holds the air in the upper layer. This is inspired and lightly reproduced from traditional Japanese homes.

建筑师采用像外套一样的透明ETFE(含氟聚合物板)创造出大气“构件”，就像覆盖瓦片或稻草的屋顶一样，能够控制温度与通风。这样的构件与外部交换能量并稳定室内环境。总而言之，该建筑群由72个管状构件组成，带有15根树桩立柱支撑。每个构件尺度为4.8m²x2.4m高，中心带有环形核心以及成对角线放射的元素。所有的构件组合在一起形成一个拱圈式的桁架结构，使其下方从山丘到海边之间的空间充满活力与自由的气息。场地的活力不仅在于空气之中，也在于文化、人群、感官等方面。人们能够轻松进入到漂浮构件下的空间。阳光照射进由雪松格栅制成的棱镜结构，使室内环境充满温馨与暖阳。

As a metaphor for a tiled or thatched roof, which holds heat and air, the architects created “units” composed of air masses covered with transparent ETFE (fluoropolymer film) that acts like a down jacket. The units exchange energy with the exterior and stabilize the internal environment. In all, the building comprises 72 cube-shaped units, along with 15 tree pillars that support them. Each unit is 4.8m²x2.4m high, with a ring-shaped core in the center and diagonal members that radiate. The units are combined and gathered together to create an arch-like truss structure, freeing up space below infused with vitality and freedom, from the layered mountainous area to the coastal side. The site’s flow not only applies to air, but also to its culture, people, perceptions, and more. People can easily access the area below the lightly floating units. Sunlight shines through a structural prism composed of cedar louvers, filling the interior environment with warm, round light.

与传统通常采用高度密闭的墙体将空间隔离的节能理念不同，该建筑营造出开放、温和的环境。该“构件”拥有留存空气的基础结构，同时还采用了灵活的桁架支撑大型空间并能够不断延伸。所有的构件相互连接，各式各样的社区活动在云朵般的构建下绽放开来。

Rather than using conventional energy-saving ideas, which secure energy in an isolated space with highly insulated and airtight walls, the architecture adopts an open, gentle environment. The “unit” is a basic structure that embraces air, but at the same time, it also composes a flexible truss that supports a large space and expands endlessly. All of the units are connected, and community activities blossom under the clouds.

单体式模结构将构建表皮包裹起来。ETFE虽然没有隔热性能，但在热辐射中的作用十分重要。在储存热能的同时，空气依然能够流通。由构建覆盖的大面积空间与地面相互连接。根据建造生态学，隔热层仅放置于地板的垂直边缘，这有助于直接传递地面能量，同时释放环境中的热量。中庭内部从深入地下100米的井中收集热量。随后热量通过能量转换进入雨水收集装置，最终用来为地板制冷或制热。

The monocoque membrane surface covers the entire unit surface. ETFE has almost no insulation performance, but it plays a role in radiating heat. Even with heat stored, air flows freely. Units cover large spaces that all connect with the earth. In reference to Baubiology,  insulation was placed only on the vertical edges of the earthen floor, which helps to directly transmit energy from the earth, and allows the thermal environment of the earth to be radiated through. In the atrium, energy is collected from a well drilled 100 meters underground. Energy is then transferred to rainwater storage through heat exchange, which is subsequently used for floor heating and cooling.

云朵之下，人们在活动中欢聚一堂，享受自由感并与社区联系一体。就像一座老房子，这里拥有土质地板与大屋顶，空气在其中流通。正方形的屋顶和云杉木组成简约又舒适的造型，为温馨的社区活动提供平静安逸的环境。

Below the cloud, people gather and spend time in their activities, enjoying a sense of freedom and connection to the community. Like an old home, it has an earth floor and a large roof, which allows airflow. The square roof and cedar wood are assembled to create a basic, but comforting shape, resulting in an environment that is calming and comfortable as a place for warm community gatherings.

在传统民居中，由于采用了土质地板，您在夏季也能够切实感受到凉爽新鲜的空气。这样的物理特性让人们能够感觉到与环境和建筑更加紧密相联。这样熟悉的感受就像在自己家中一样放松。在夜晚，构件组合交替闪烁，不仅吸引了周围人的目光，也引起海对岸人群的注意。随着时间推移，越来越多的活动与人们的生活和社区融为一体。人们渴望重新回到高度共融的无阻隔环境之中。

In old folk houses, you will actually feel cool and refreshed on a hot summer day, because of the earthen floor. Such physical sensation and appreciation will make a person feel more connected to the environment and architecture. A familiar feeling as if it’s someone’s home, relaxed. At night, the collection of units becomes a twinkling light, attracting people from not only the surrounding area, but also from across the sea. As time goes by, more events and activities will be held as an integral part of people’s lives and the community. People will feel the urge to return to a highly compatible environment with no barriers.

从空中看，观海之园（See Sea Park）仿佛一片活力之丘。它像都市之城一样，是一片可持续发展的组织。

From the sky, the figure of the See Sea Park will appear almost like cells in a living creature. It lives and makes a sustainable organization like metropolitan urbanization.
