“大家的森林：岐阜媒体中心”是一座图书馆综合体，于2015年7月对外开放。该处亦为岐阜县标志性景观——雄踞金华山顶的岐阜城的所在地。岐阜媒体中心位于JR岐阜站以北2公里，长良川赋予该地丰富的地下水资源。

为了打造新的文化中心，为城市注入活力，当地政府计划在周边兴建综合性建筑和广场，并以此为题举办设计竞赛。本所于2011年2月获选为中标设计单位。

该建筑共两层，长宽尺寸为80 x 90米。第一层正中为玻璃书库，藏书60万册，内部环境极其安静。书库周围依次为展览馆、多功能厅和市民活动交流中心。

第二层是大型阅览室，未设置隔离墙。阅览室藏书30万册，共设各式阅览座910个。

圆形阅览室和服务台上方倒悬着11个直径8-14米的半透明“大伞”。“大伞”名为“Globe”，由聚酯纺织物制成，呈倒扣漏斗状。“Globe”促使上方的空气缓慢流动，散发出柔和的光线，为读者提供舒适的室内环境。

屋顶由切面大小为120 x 20毫米的本地木材铺叠而成，呈平缓波浪状。薄木板相互层叠，从三个方向编织。“Globe” 悬挂之处的屋顶亦顺势升起，屋顶的波浪结构优化了“Globe”的功能。屋顶在四周群山的映衬下，形成了一幅恢宏而和谐的城市景象。

该地林木繁茂，建筑西侧紧邻一条240米长的林荫漫步道，南边则是45米宽的广场。建筑二层设三个露台，各具特色，为人们提供了一个休闲舒适的环境。

With the “Globes” channeling natural energy into the building, the utilization of underground water as“Globe”向建筑传输自然能源，同时，建筑利用地下水作为热源为地板辐射供暖/制冷，以及在屋顶安装太阳能电池板，从而形成一套均衡机制。凭借上述节能设计，该建筑有望较二十世纪九十年代同等规模建筑减少至少50%的能耗。

“人与自然共生”的主题在日本由来已久，在追求这一主题的过程中，我们并非通过明确划分或隐藏空间降低能耗，而是通过创建一个舒适、节能的环境，使人们能真正感受自然的活力，并在富有活力的空间里繁衍生息。

该建筑的建成开放，令使用者仿佛置身城市自然景观之中，并在不同空间使用者之间建立起新的纽带，毫无疑问实现了人与自然共生。

‘Minna no Mori’ Gifu Media Cosmos is a library complex, opened in July 2015. The site has a symbolic view of the city: Mount Kinka with Gifu Castle on its top. It is located 2km north from JR Gifu Station and has abundant subsoil water from Nagara River.

In order to create a new cultural centre and to activate the city, there was a design competition for a complex and plaza around it. We were selected as the designer in February 2011.

The building is made up of two stories, about 80m x 90m in dimension. The fi rst fl oor has a glass book archive that accommodates 600,000 books, located in the middle of the large plan within the most stabilized environment. An exhibition gallery, a multi-purpose hall and a civic activity and exchange centre are placed consecutively around the archive.

The second fl oor is one large reading area with no walls, and has shelves for 300,000 books as well as various kinds of browsing seats (910 seats in total).

Large translucent umbrellas named “Globe”, hang above the circular reading spaces as well as the reception counter. The “Globes” are made of polyester fabric and are shaped like an inversed funnel.Eleven “Globes” of 8m–14m in diameter create gentle air movements and soft diffused light from above, providing a comfortable indoor environment.

The gently undulating wooden roof is made out of domestic-scale timber of 120mm x 20mm in section.The thin timber slats are stacked on top of each other, laminated in three directions. The function of these “Globes” is optimized by means of the roof’s undulation, as the roof rises where the “Globes”are located. The roof being embraced by the surrounding rows of mountains create a grand and harmonious scene for the city.

The site had been abundantly planted with trees, where a 240 metres long promenade of trees fl ank the west side of the building. On the south there is a plaza that is 45m in width. The three terraces on the second fl oor each has its own character, creating distinctively comfortable and relaxing areas.

a heat source to generate radiant fl oor heating and cooling, as well as the use of solar panels on the roof, all combined into a balanced mechanism. With all these features the building is expected to reduce the primary energy usage by at least 50%, compared to a building of the same size if it were in the 1990s.

Instead of clearly dividing or concealing spaces to reduce consumption of energy, we create a comfortable and energy-saving environment while in pursuit of connection with nature, a theme that has long existed in Japan, allowing people to feel alive and be nurtured within the space.

It can be said that this is clearly the case after the opening of the building, with the users enjoying the space as if they are within a townscape, as well as new found connections between different people who uses this space.
