Madrid skyscraper Caleido Tower has excelled in sustainable design after installing a globally proven KNX building automation system (BAS).
The 181m high skyscraper in Madrid met Leadership in Energy and Environmental Design (LEED) certification, a framework which consists of various rating systems tailored to different types of buildings, spaces and communities to assess the sustainability of a project. Caleido Tower, which is the seventh tallest building in Spain, achieved Gold which means it “serves as [an] exemplary model of sustainability, showcasing the potential for significant environmental impact reduction through thoughtful design and operation”. The building achieved this by using natural light with the help of an advanced lighting control system by German manufacturer B.E.G., whose UK headquarters are based in Surrey. Caleido Tower also has also incorporated facial recognition, intelligently controlled lifts and air filtration and ventilation systems. The project, in the shape of an inverted T, has been divided into four areas: an educational area with 35 floors used by IE Business School; a wellness clinic; an underground car park and a restaurant and shopping area. The technology protocol used in the Caleido Tower was KNX, a globally proven bus system within building automation, which brings together multiple systems enabling the uniform networking and visualisation of intelligent devices. B.E.G. predominately used the PICO sensor – one of the smallest KNX detectors in the world – for this project due to its size. Despite its diameter of only 33 mm, it has a range for motion detection of 10m transversely, 6m frontally and 4m for seated activities. This means that it detects even the smallest movements, such as the operation of a computer mouse. In addition to a light output (controllable or switchable) and a slave output for extending the detection range, the B.E.G. PICO also has three HVAC outputs with which energy-intensive systems such as air-conditioning units can be controlled. The light output can be used both as an occupancy detector and as a twilight detector (motion-independent control/switching). The B.E.G. PICO also has functions such as a temperature sensor, presence simulation, corridor function, orientation light function, short presence and self-adjustment of the follow-up time.
