一家电子安全系统制造商希望在马德里东北部阿尔卡拉德赫拿勒斯的新总部建造一座“独特的生物气候”大楼。AlarconAsociados提出了一种形式(表现)和(气候)功能协同工作的设计。客户也是这座建筑的所有者，这或许可以解释他们在支持这种非常规设计方面的大胆之处。

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.

朝楼顶，红色现浇混凝土板的悬臂越来越远.他们减少了正面的直接太阳增益约90 %，使移动百叶窗不必要。在这座建筑中，建筑师们第一次使用了一个自建的HOLEDECK地板系统，里面有完整的空心空间，所有的建筑服务都可以被路由。这就为每层节省了大约50厘米的建筑高度，因为不需要悬挂天花板。由于桥墩之间的跨度很大，长达12米，而且几乎完全对称，仅受西南面室外楼梯的干扰，1000平方米的办公楼层可以不受限制地布置。木棒系统正面有50%的上光率和100毫米矿物羊毛绝缘的不透明斜面板。在外部，这些是面对0，8毫米金色阳极氧化铝和内部橡木板。

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.

特别是这座建筑的对角线支撑在其中心线和角落，继续在强大的桥墩与V形截面向上。所有垂直风管，以及用于进气和排气通风的热交换器，都包含在这些结构中，AlarconAsociados称之为建筑物的“鼻”。进气口从屋顶上方吸入，然后通过8根土管(每个码头一根，每根180米长)输送到地下，最后通过码头返回办公室。废气也流过桥墩，然后从屋顶流出。由于空气的预调节和夜间的自动交叉通风，不需要传统的空调系统。为了加热房间，混凝土楼板可以通过镶嵌管道进行热活化。热主要由屋顶上的太阳能集热器提供，有一个燃气锅炉作为备用系统。

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.

建筑师们计算出，与传统建筑相比，这座建筑的照明能耗要低40%。他们说，没有可移动的百叶窗和悬臂式混凝土地板提供的遮阳，应该有助于尽量减少白天使用电灯的情况。人工照明完全由LED灯具提供，基本照明为200勒克斯，但如果需要的话，工作空间的亮度可以直接增加到500勒克斯。

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.
