Saving energy sensitively
A library with a view of the nearby sea: “LexIcon” is located in the Irish county Dún Laoghaire-Rathdown. The architects Carr Cotter & Naessens
designed the three-story, granite-clad building whose wooden floors and spacious, bright rooms offer a pleasant reading environment. Ecological factors such as heat efficiency were taken into account during construction. In this context, a sunblind system was installed that responds to changes in light and temperature.
Temperature and light sensors as well as motors by Nice enable the precise measurements in the sun protection system. The tubular motors of the Nice Era series control the opening and closing of the sun protection elements, while the sun/temperature and brightness sensor “NiceWay sensor” measures the light conditions and regulates the elements such that the incoming sunlight or brightness in the room remain within the desired values. Moreover, the blinds can be radio-controlled centrally if required. The sensor ignores disturbances such as people’s shadows or passing clouds. Regulating the temperature value and light intensity increases the building’s thermal efficiency, i.e. the effect of the sunrays is regulated and the building’s energy requirement reduced. The data recorded and entered are conveniently shown on the sensor’s graphic display.
