Year Book 2016Environmental ReviewThis is a facility to serve during normal times as a center to promote tourism and raise awareness of disaster prevention, and also to function as a refuge during disasters. It encloses three facilities – a meeting room, the disaster prevention and tourist center, and toilets – within a veranda-like engawa space of about 70 m. The site is located near the pine-clad islands of Matsushima, one of the celebrated Three Scenic Views of Japan. To harmonize with the landscape, the facility uses natural materials such as a tile roof and traditional charred Japanese cedar cladding. The building is a wooden structure that makes extensive use of natural energy, for example in its monitor roof for natural lighting and ventilation.The facility has a 12-m long span of laminated wood . It was designed as a exible and easy-to-use space with an earthquake resistant structure. The engawa space functions not only as a temporary refuge during disasters but also as a multi-purpose space that links interior and exterior during disaster awareness and other events.平常時には防災意識啓発や観光まちづくりの場として、災害時には避難所として機能する施設。会議室、防災まちづくりセンター、トイレの三つの施設を約70mの「縁側空間」で結んでいる。日本三景・松島の景観保持に配慮し、瓦屋根や焼杉板など自然素材を利用した木造建築としており、越屋根を利用した自然通風、自然採光など自然エネルギーの積極的な利用により省エネにも配慮した。構造は耐震性にも配慮しながら、集成材梁による12mのロングスパンとし、フレキシブルで使いやすい空間とした。縁側空間は一時避難場所としてだけではなく、室内と一体となった防災イベントなど、多目的に利用できるようにした。環境注目プロジェクト石田沢防災まちづくり拠点Notable Environmental Project – Ishidazawa Disaster Prevention and Tourist Center研究開発者間のコミュニケーションを豊かに、分野を横断してシナジー効果を発揮する施設づくりを求められた。そこで全館7層連続の吹き抜け空間と階段を組み合わせ、フロアを超え自然に交流が生まれる空間を計画した。吹き抜け空間を活用した「風を取り込む工夫」として、南北の開口部を開放し自然換気を促す構成。また「建物内の熱を有効に利用する工夫」として、夏季には吹き抜け上部に溜まった熱を自動的に排出する自然換気窓の設置と冬季には溜まった熱を下階に循環させる仕組み。さらには「快適な執務環境をつくる工夫」として、吹き抜け部の床下空調や温度湿度を個別に制御し快適性と省エネを両立するDESICA空調、会議室・役員室は空気放射冷暖房システムを採用した。また、角度を変化させた外装ルーバーにより、視界の開放と直射日光の制御を両立している。環境注目プロジェクト横浜ゴム平塚製造所　新技術棟Notable Environmental Project – Yokohama Rubber Hiratsuka Factory New Technology BuildingThe brief was for a facility that would stimulate communication between researchers and facilitate synergies between dierent elds. In response, our design combines stairways with an atrium linking all seven oors to create a space where communication across oors occurs naturally. The atrium also brings air into the building, with openings at the north and south left open to enable natural ventilation. To make effective use of the heat inside the building, a ventilation window was installed at the top of the atrium to automatically release the hot air that accumulates there during the summer. During the winter, the hot air is circulated back to the lower oors. To increase the comfort of the working environment, the energy-saving Desica air conditioning system was installed to provide both air conditioning under the oor of the atrium and temperature and humidity control. A radiant cooling and heating system was chosen for meeting rooms and executive oces. On the facade, louvers with changeable angles allow a free view out while also controlling direct sunlight. 017
