Botânica Office, with its façade of climbing plants filtering the afternoon sunlight, proposes a corporate building model that connects the building’s users with nature, the city and the sunset from the central void, as well as fostering social interaction on its terraces.

This void, shaded by its very shape, was conceived as a visual and physical extension of the public space to encourage social and corporate gatherings on the numerous public terraces. The public space also permeates the first floor of the building to connect the sidewalk to the shopping mall, located behind the Botânica Office, integrating this horizontal public axis with the vertical one of the terraced void. The public void is crowned by a rooftop that houses a bar and restaurant with panoramic views over the city.

The benefits of the vegetated façade are many: air pollution filtration, temperature reduction, heat filtration, reducing the need for air conditioning, filtering afternoon light by allowing the use of simple, colorless glass, reducing the glare that is very common in Amazonian latitudes and reducing the need for artificial light. In addition to these benefits, there are also health benefits, such as proximity to nature, which generates well-being, increasing productivity and creativity, as well as boosting immunity, reducing cortisol (stress hormone), lowering heart rate, relieving depression and lowering blood pressure.

This project won a closed competition. Aware of the impact of construction on the environment, we dared to propose a building with only 15 floors because it had 10% less total built area (due to less repetition of circulation) and a 20% smaller façade area than a 25-storey building (permitted on site) with the same total net sales area (11,000m2). In other words, with a bold initial decision, we reduced construction costs and respected the environment.

As mentioned above, the benefits of integrating nature into architecture are numerous, but the system of eaves and climbing vegetation in modular systems brings other originalities and innovations: 10 types of climbing plants will be planted that will generate an evolving landscape depending on the seasons; the green façade will not be used as a green wall with a masonry background, as in most green façades, as the climbing plants will be used in front of a simple glass skin to generate a natural filter from the setting sun and create a natural and pleasant atmosphere in the work environments inspired by the sunlight that passes through the canopy of the Amazon rainforest. From various work environments, the city skyline blends with the light filtered by the vines.

Currently under construction, this type of green façade to filter light on this scale will not only be an innovation in the city of Manaus, but also at national and world level, reaffirming the need to look at the Amazon from an architectural perspective.

博塔尼卡辦公大樓（Botânica Office）的立面覆以攀緣植物，不僅能過濾午後日光，更以全新的企業建築理念連結使用者、自然、城市與中央中庭的日落景觀，並在露台上促進社交交流。中庭藉由其特殊造型在視覺與空間上延伸公共領域，鼓勵人們在各層公共露台進行社交與商務活動；公共空間亦延伸至建築一層，串聯人行道與後方的購物中心，將水平的公共軸線與中庭露台的垂直軸線融為一體。中庭最上方為屋頂平台，設置酒吧與餐廳，可一覽城市全景。

植被立面帶來的效益相當豐富，包括空氣淨化、降溫、隔熱、降低空調需求、過濾午後陽光（使得建築可採用簡潔的無色玻璃）、減少亞馬遜地區常見的眩光，以及降低人工照明的依賴。除此之外，也提供多項健康益處，如提升幸福感、增進生產力與創造力、加強免疫力、降低皮質醇與心率、舒緩憂鬱並穩定血壓，讓人們在日常工作中更貼近自然。

本案在一項封閉式競賽中脫穎而出。基於對建築環境影響的高度意識，團隊大膽提出僅興建15層的方案；與場地所允許、同樣具備11,000平方米可銷售面積的25層建築相比，總建築面積減少10%（因動線重複度降低），立面面積亦縮減20%。換言之，藉由這項大膽決策，不僅降低建造成本，也更友善環境。

如前所述，將自然融入建築帶來無數益處，而本案採用的模組化屋簷與攀緣植物系統亦展現創新精神：建築將種植10種攀緣植物，隨季節變化呈現不斷更新的景致；與多數綠化立面不同，這裡並非以磚石為基底的綠牆，而是讓攀緣植物攀附於純淨的玻璃幕牆前，以自然濾光重塑舒適宜人的工作氛圍，其靈感源自亞馬遜雨林樹冠中灑落的陽光。從各處工作空間望向外部，城市天際線與藤蔓濾過的光影交織成獨特風景。

目前正興建中的這座大規模濾光綠色立面，不僅在馬瑙斯市，在全國乃至全球範圍皆屬創舉，再次證明以建築視角重新審視亞馬遜的重要性。
