前二週陸續介紹了西班牙建築事務所ACXT IDOM的精采作品，這次順便也來介紹這間事務所由舊倉庫改造而成的總部。這間面積14,400平方公尺的總部大樓位於當地畢爾包Deusto運河旁，分別規劃了辦公區、研究與發展中心與交流區等，功能性十足。

原本的舊倉庫屋頂總是堆滿了貨物，這倒也成了總部設計時的構想來源，改為以綠色植被覆蓋屋頂的方式來呈現，並同時遮掩住所有的空調設施，使得總部大樓外觀看來更加地簡潔。屋頂綠植被設計所形成的起伏山坡樣式成了一處社交場所。其中的平坦處以自然草皮設計，而遮蓋空調設施的綠植被則特地以人工草皮處理以方便日常的維護及整體重量上的考量。綠屋頂的設計同時也提供了吸收噪音、熱能與CO2的功效。

為了考慮防晒、能源消耗及與內部設計一致的問題，設計團隊選擇使用置於玻璃前的大面積遮陽板（brise soleil），如此的造型不但像極了從屋頂綠植被延伸而下的設計，更突顯出總部大樓獨特的外觀，而在遮陽板上一些特地設計的角度及陽台的設計更是為了能讓消防員進出方便的考量，整體而言在美學、成本及維護上獲得最佳的平衡。

總部大樓外部材質主要為鋁材、型鋼、石棉及高強度玻璃，內部保留了倉庫原有的外露樑結構，而原本提供貨物的昇降梯至屋頂的設備則改造為以玻璃包覆的造型階梯，同時也是一處能同時欣賞辦公區與運河景色的地點，而原封閉的昇降梯屋頂出口處也改成開放式的圖書館，提供一處激發靈感來源的地方。

一樓處為一處面積為400平方公尺的展覽廳，並設計了如投射般的室內結構，讓中央處有著極高的挑高，並讓木結構連續跨過樓板、牆及天花板，讓設計如同是船體般的結構，與一旁的運河做了最佳的回應。

在節能上總部大樓也做了最佳的示範，大樓不但有低耗能的衛生設備，屋頂上也設置了儲存雨水的水塔、自動照明系統、暖通空調、獨特的漫射系統及太陽能板，而草皮的下方則設置了自動灌溉系統。事務所特別在暖通空調與照明系統旁以不同顏色的冷樑做為標示，表示這些系統與傳統系統相較之下可節省約60%的能源消耗量；而一樓處的雨水收集塔，也能減低大雨時產生洪流的機會。

總部大樓另一重點就是要創造出一處大型、通風與交流視線良好的工作場所，讓同仁們雖然處在不同的部門也有著位於一處超大型開放空間之感，在樓層的中央更是設置了一處秘書區，以及一處電話區以降低像是一般辦公室中通話時對其他同事的干擾。事務所以較多的會議室與團體工作室取代了傳統的辦公室，製造出更開放式的工作環境，２/3辦公區更配置了三片滑動式的大玻璃牆，隨時可與工作區域做為連結。當然，開放式空間可能產生的噪音干擾問題，事務所則利用地毯，桌上與天花板上孔狀的石棉以及冷柱上的消音帷幕來加以解決。總部地下室的樓板高度因為低於運河最低潮汐的高度，為了避免河水滲透與潮濕問題，並確保適當牆的通風，做為基礎的地下室則包覆著隱蔽式的網狀物。

The new IDOM Group offices are located in the old bonded warehouse in the Deusto canal, in Bilbao. It has 14,400m2 destined for offices, research and development areas such as the white-room and the prototypes workshop, and social spaces.

Outwardly, and from the first idea, the design has developed from the occupation manner of the roof, which was fully occupied by goods that were stored in the building. An imaginary green carpet has been designed as if simply placed over the roof, hiding all air conditioning units which in most office buildings are visible, with the resulting sound and visual impact. Certain topography arises as a result of the adaptation of the "carpet" on the machines. Folds and surfaces that resemble a hill on which to stroll in the moments of relaxation and conversation with peers for this is the floor on which the rest-area of the building is planned. The flat part of the "carpet" is natural grass. For maintenance and weight reasons, the part that covers machinery, the folded one, is artificial turf.

We wanted to give the façades a design which was highly protective of the sun but that did not compromise the view from the inside and that would help us control solar radiation and thus energy expenditure. So we turned to some “brise soleil” whose design emerges as an imaginary extension of the roof carpet as something that has been stretched over the façades and "folds" in its singularities: an existing balcony facing the canal, the entrance, access points for firemen through the façade and other unique areas. During the design process we developed several designs. Finally we settled for a horizontal solution which had the optimal balance of aesthetics, cost and maintenance: extruded aluminium profiles supported by HEA steel profiles with AISI 316 stainless steel screws. The building envelope is solved with aluminium composite and rock wool in the blind parts and with high performance glass in an aluminium framed curtain wall in the spaces between pillars. Between the slat rails and the façade, a platform for external cleaning of the glass has been designed.

Inside, the design combines existing elements with new ones. The great beams of the original structure (a port warehouse) are left uncovered in most of the floors. The openings used by the old car-lifts that lifted cargo up to the roof are now occupied by a splendid main staircase and glass covered lifts that will offer views of both the offices and the canal. On the top floor of the tower, where the noisy machinery of the car-lifts used to be enclosed, there is now a library, a space for ideas to flow in silence.

On the ground floor, it was necessary to eliminate 3 pillars to accommodate a 400 m2 exhibition hall. Three discharge frames, having great height in the middle, determine the design of the room: a continuous wood covering over floors, walls and ceilings, which adapts to the shape of the discharge beams through a geometry of sea echoes, like the hull of a boat.

The building has innovative energy efficiency measures: very low consumption taps and sanitary equipment; rainwater storage tanks on the roof, under the grass, for the automatic watering of the garden; automatic lighting regulation systems, sun protection slats on façade, photovoltaic panels on the roof of the tower and a unique diffusion system based on movement and HVAC by water systems. For the latter, different coloured beams that round up the HVAC and lighting in a single element have been designed and installed: the cold beams. It is estimated that these measures will bring about energy savings of nearly 60%, compared to the normal consumption of a similar building.

The green roof provides a number of additional benefits that affect the nearby urban environment such as the reduction of the heat island effect, acting as a noise and CO2 absorption element thanks to its vegetation. Also, the possibility of retaining water that, accumulated in a run-off water tank on the ground floor, contributes to the control of water in times of storm or heavy rains.

The cold beams integrate water batteries, lamps and lighting sensors and are installed between the existing large beams, which, due to the fact that they are uncovered, make the most of their inertia given by their great mass to mitigate temperature differences between day and night, when the HVAC system is off or on. The HVAC works with the water that feeds the batteries with no mechanical parts. It helps to create an effective and durable system, requiring minimal maintenance. The diffusion system for ventilation is displacement by which the air comes out from the ground, at very low speed, and rises, as it warms up, towards the ceiling where it comes in contact with the batteries and then descends by natural convection. A draft-free installation, very comfortable and quiet.

The colour of the beams contributes to making the workspace friendlier, away from the usual monochromatic ceilings in the open office spaces, and closer to the chromatic vibration of greens and ochre colours that are seen when sitting under a tree.

On the perimeter of the building, the façade adjacent areas, in order to tone down the excess of natural light, walls and ceilings have been painted anthracite grey. The interior has been left stained white colour, the colour that the existing structure had, which is left raw, uncovered.

An important objective of the project was to create a large and airy workspace, with great visual communication between and within departments, without barriers between different levels of function and membership of the IDOM firm. In the centre of the floors, a lobby serves in some cases to establish a zone of secretaries and in others, seating area to talk on the phone without disturbing other colleagues.

Very few offices haven been planned, yet many meeting and teamwork rooms. To avoid creating psychological barriers between the office rooms and the open areas, we planned no conventional partitions with a fixed glass and door, but rather three-pane-glass sliding screens that allow for 2/3 of the office front to be open towards the work area.

Noise and open workspaces are often synonyms, so we paid special attention to sound absorption surfaces: on the floor, a carpet with state of the art 6.6 fibres; on the front of the tables, perforated plates with rock wool and in ceilings, the cold beams have a lining designed with a sound-absorbing veil and perforated plates so that their position between the existing beams serves as an acoustic trap.

This strategy is repeated in the visitor rooms, where we designed a rock wool wall cladding, absorbing veil and electro galvanized dichromate perforated plates, an industrial finish used to make filters and sieves.

The floor of the basement, which the building didn’t have before, is below the low tide level of the Deusto canal. To ensure adequate ventilation some walls, and to minimize filtration and dampness problems, the pillars – foundations are covered with camouflage mesh.

ACXT-IDOM
ACXT, an architecture services provider, started off as a society of professionals who came together with the aim of offering a quality alternative within the field of architecture, becoming a valid option for the professional development of architects interested in high level architecture. Its philosophy marks the creation of a professional framework of collaboration and avail of its members’ synergies, always from a full understanding of architecture: both technically and culturally.
The philosophy that guides ACXT is based on the respect for traditional values, still in force today, generated during the secular practice of architecture. ACXT is committed to signature architecture, understood in terms of respect for the creative values that architects, with a clear customer orientated practice, have historically contributed throughout the whole intellectual and constructive process. ACXT aims to offer a quality solution to the huge social credit that the practice of architecture implies in its double commercial and cultural dimension.
ACXT-IDOM has become the largest provider of professional services to architecture in Spain and one of the most relevant worldwide. In the January 2015 edition of the BD World Architecture’s Annual Survey, a British publication that gathers the hundred most important architecture firms worldwide, ACXT-IDOM was ranked number 52.
