開発が進む地区でのオフィス建替計画。「陰影を纏う」をテーマとし、外観からサインに到るまで展開することで、独特の表情を持たせた。外装は、層間区画とメンテナンス通路を兼ねたPCスラブで構成された水平ラインと、フロア間をつなぐ180本の縦型アルミルーバーによって、彫りの深い表情を持たせた。日射制御の機能と太陽光、人の視点の変化により、多様な表情を表出することを意図した。また、24時間対応の非常用発電、デシカント空調、LOW-eガラス、波型鋼板耐震壁、風による振動低減対策としてのATMDの採用等、競争力あるスペックと整形な専有部を実現し、ランドマークとなる存在感の獲得と共に充実したスペックを備えた競争力あるオフィスビルとした。(梅野 圭介)サンアイ茅場町ビルSan ai kayabacho buildingFacade clad in light and shadow陰影を纏うファサードOwner: SAN AI CO.,LTD.Location: Chuo-ku Tokyo Main Use:Office,ShopDesign and construction work: Takenaka Corporation·Architects: Jun Shinozaki and Keisuke Umeno·Structural: Naoki Asou and Atsunari Hanai·M&E: Dai Kawarai Kenichi Saitou and Masataka NagaharaAkira Hanabatake·Site manager: Tooru SakumaSite area: 451.99m2Building area: 348m2Total floor area: 3,202m2Construction: SteelNumber of stories: 10 floors above ground and 1penthouse floorConstruction term: June 2013 to June 2014建築主：株式会社サンアイ所在地：東京都中央区主要用途：事務所・店舗設計施工：竹中工務店・設計：篠崎淳・梅野圭介・構造：麻生直木・花井厚周・設備：川原井 大・斉藤賢一・永原正隆・作業所長：佐久間　徹敷地面積：451.99㎡建築面積：348㎡延床面積：3,202㎡構造：S造階数：地上10階　棟屋1階工期：2013.6～2014.6This project involved the reconstruction of an office building in an area that is in the process of being developed. The theme of “clad in light and shadow” was employed from the outward appearance to the signs to give the building a distinctive look. A deeply chiseled appearance is created by the horizontal lines of the prestressed concrete slabs used for the exterior (including the interlayer sections and the maintenance corridors) and the 180 vertical aluminum louvers placed so as to connect the floors. The goal was to create diverse expressions through the sunlight control functions, the sunlight and the changes in people’s vantage points. The building also has regularly shaped exclusive occupancy areas and competitive specifications that include an emergency generator that can be operated 24 hours a day, desiccant air conditioning, low-e glass, corrugated steel earthquake-resisting walls, and the use of active tuned mass dampers (ATMD) to reduce vibrations caused by wind. The result is a competitive office building that combines a landmark presence with outstanding specifications.
