布宜諾斯艾利斯新市政大廈是福斯特建筑事務所在阿根廷的首個市政項目。項目跨越了帕得利修公園區(ParquePatricios )一整個街區，這個建筑是活躍社區的催化劑，采用了一個結合環保的創新設計，具有高度靈活的室內階梯式辦公樓層布局。

入口是一個穿過四層樓高，直通屋頂的中庭。落地玻璃幕墻讓室內空間充滿了自然光線，并創造與旁邊公園視覺上的聯系。四個工作區樓層向后退讓，產生一個室內階梯序列。所有的樓層都由頂部采光的流線連接，并有兩個大型的景觀庭院穿插其中。活動空間是開放的，有自然采光和開闊的視線，確保了不同部門之間的良好交流，和提高集體感。寬敞的樓面板來自于一個八米的柱網，這種柱網允許多種建筑布局，這個建筑最初是作為銀行總部委托的，而它固有的靈活性使它能無縫過渡為政府辦公室。其他配套設施包括了一個咖啡館和一個由木材鑲面的300 座的禮堂，這個禮堂能用于當地社區舉辦活動。

從外部看，這個建筑以其波浪形的屋面板為特點，屋面板由柱子支撐，還延伸出很深的懸挑，為入口廣場和立面提供遮陽。在內部，混凝土澆筑的筒狀拱的屋頂暴露出來。工業材料的使用加強了帕得利修公園區(ParquePatricios )以前的工匠特色。而混凝土拱腹的熱質量結合冷卻梁，有助于自然調節溫度和保持辦公區涼爽。這將成為阿根廷第一個達到LEED 銀獎標準的可持續性公共建筑。方案的每一方面都經過設計來回應當地的氣候，包括每個立面的組合，東面和西面由通高遮光格柵幕墻組成以遮陽避熱。

The new Buenos Aires Ciudad Casa de Gobierno is a sustainable new city hall for the Mayor and 1,500 staff - and the practice’s first civic project in Argentina. Spanning an entire city block in Parque Patricios,the building is a catalyst for the regeneration of the neighbourhood and combines an environmentally efficientdesign with an innovative, highly flexible internal arrangement of terraced working floors.

Entry is through a soaring four-storey-high atrium. Full-height glass walls fill the space with natural light and create a visual connection with the adjacent park. The four tiers of workspaces step back to create a sequence of internal terraces. All floors are connected by top-lit circulation routes and punctuated by two large landscaped patios. The activity spaces are open, naturally lit and visible, ensuring good communication between departments and promoting a sense of community. The generous floor plates are based on an eight-metre grid, which allows for a wide variety of layouts- the building was originally commissioned as the headquarters for Banco Ciudad, and the inherent flexibility of its design has enabled a seamless transition into government offices. Further facilities include a café and a 300-seat wood-panelled auditorium, which can be used for events by the localneighbourhood.

Externally, the building is characterised by its flowing roof canopy, which is supported by pillars andextends in a deep over hang to shade the entrance plaza and facades. Inside, the concrete barrel vaulted roof is textured and exposed. The use of industrial materials reinforces the formerly artisan character of Parque Patricios, while the thermal mass of the concrete soffits, combined with chilled beams, help to naturally regulate the temperature and keep the offices cool. It will be the first public building in Argentina to achieve the environmental award for sustainability of LEED Silver standard.Every aspect of the scheme was designed in response to the local climate, including the composition of each facade - the eastern and western elevations are shaded by a screen of louvres, which rise the full height of the building.

福斯特爵士說：“可持續性非常密切地關系到本地的資源和氣候，布宜諾斯艾利斯市政廳通過被動的環保手段自然地減少能源消耗，展示建筑怎樣與自然共同合作。屋頂延伸出來像檐篷一樣提供遮陽，它波浪形的混凝土結構既是作為市政建筑的標志，同樣具有調節溫度的功能。東面和西面的遮陽格柵能防止強光直射室內，而中庭讓陽光能進入大樓的中心，這樣一來，設計與地方特征和氣候特點產生呼應。該項目在復興這個城市前工業地位方面起到至關重要的作用。”

Lord Foster said: “Sustainability relates very strongly to local resources and climate, and Buenos Aires CiudadCasa de Gobierno is a great demonstration of how architecture can work with nature viapassive environmental means to naturally reduce energy use. The roof extends like a canopy to provide shade, its flowing concrete structure is both symbolic as a civic building and functional in regulating temperatures. Shading louvres on the east and west protect the interior fromdirect glare,while courtyards allow sunlight into the heart of the building - in this way, its design is very much a response to place and climate.The project has played a vital role inregenerating this former industrial quarter of the city.”

福克斯建筑事務所的負責人大衛·薩默菲爾德說：“這是我們事務所一個重要的里程碑，我們對我們在阿根廷第一個市政項目是一個如此重要的布宜諾斯艾利斯政府辦公樓感到十分自豪。它的設計在社會和環境方面非常適合當地的實際情況，我們的目標是創造一個高度靈活的建筑，響應城市怡人的氣候和公園邊上的獨特區位，為振興社區提供積極的作用。”

David Summer field, Head of Studio, Foster + Partners: “This is an important milestone for the practice, and we are proud that our first civic work in Argentina is such an important government office for Buenos Aires. Its design is very much aresponse to the local context,socially and environmentally - our aim has been to create a highly flexible building, which celebrates the city’s wonderful climate and the unique park-side setting, and will make a positive addition to a revitalised neighbourhood.”
