这是由Alarcón + Asociados设计的Logytel I+D公司总部。一家电子安全系统制造商厂商想将其新公司总部设在马德里东北的Alcalá de Henares。设计团队决定在该方案实现形式与功能的结合。客户亦鼓励一份与众不同的方案。

该屋顶可减少90%的太阳直接辐射，因此不需要设置百叶窗。该建筑还首次采用设计团队自主研发的HOLEDECK地板系统，所有建筑服务设施集中布置在该系统里。由于设施不再布置在天花板，建筑层高减少，每层约减少50厘米。对称状的柱墩间跨度约12米，因此这个1000平方米的办公室空间不受任何结构物阻隔，除了建筑西南角的户外楼梯。建筑外立面使用了半透明的木材、不透明的拱肩镶板和矿棉绝热制品等构件。建筑室外使用了0.8mm厚的金色铝合金，而室内使用橡木板。

该建筑中心线和四角的大型柱墩，其横截面呈V型对称，给人以不断向上、强而有力的感觉。在这些柱墩构筑物还布置了垂直通风道、换热器的排气通风等，担当着“鼻子”的功能。由于空气预处理及夜间交叉通风，因此该建筑无需配置传统的空调系统。混凝土地板可通过热气管进行加热。热量由屋顶的太阳能集热器提供，另外还设有燃气备用系统。

该建筑比传统建筑节约约40%的照明电量。由于没有百叶窗，悬挑得混凝土楼板提供阴影区，有助减少建筑白天使用电灯。人工照明采用LED灯具。

A manufacturer of electronic security systems wanted a “unique and bioclimatic” building for its new headquarters in Alcalá de Henares northeast of Madrid. Alarcon Asociados came up with a design in which (expressive) form and (climatic) function work hand in hand. That the client is also the owner of the building might explain their boldness in endorsing such an unconventional design.

Towards the top of the building, the red coloured in-situ concrete slabs cantilever increasingly farther out. They reduce the direct solar gain on the facade by about 90 %, making movable blinds unnecessary. In this building for the first time the architects used a self-developed HOLEDECK floor system with integrated hollow spaces in which all building services could be routed. That saves around 50 cm of building height per floor, because suspended ceilings were not needed. With their enormous spans of 12 metres between the piers and their almost complete symmetry, which is only disturbed by the outdoor stairs on the southwest facade, the 1000 m² office floors can be arranged without restrictions. The stick system facades made of timber have a glazed percentage of 50% and opaque spandrel panels with 100 mm mineral wool insulation. On the exterior, these are faced with 0,8 mm gold-coloured anodized aluminium and on the interior with oak panelling.

Particular to this building are the diagonal buttresses on its centre lines and corners which continue upwards in powerful piers with V-shaped cross-sections. All vertical air ducts, as well as the heat exchangers for the intake and exhaust ventilation, are contained within these structures, which Alarcon Asociados call the “noses” of the building. The intake air is drawn in from above the roof, then sent underground through eight earth pipes (one per pier, each 180 metres long) and finally back through the piers to the office levels. The exhaust air also flows through the piers and then out over the roof. Due to the preconditioning of the air and the automatic nightly cross ventilation, no conventional air conditioning system was needed. To heat the rooms, the concrete floor slabs can be thermally activated by means of inlaid piping. Heat is mainly provided by solar collectors on the roof, with a gas boiler serving as back-up system.

The architects calculate that the building consumes 40% less energy for illumination than a conventional building. The absence of moveable blinds and the shading provided by the cantilevering concrete floors, they say, should help minimise the use of electric light during daytime. Artificial lighting is provided exclusively by LED-luminaires with a basic lighting of 200 lux, but the brightness can be increased directly at workspaces to 500 lux if needed.
