The Triamant living environment for (young) elderly people in the municipality of Ronse guarantees a beautiful green environment. Their mission is, therefore, to reduce their ecological footprint to a minimum. The lighting and sun protection system are controlled intelligently using a variety of KNX components. The weather station protects against strong gusts of wind, while the various pyranometers ensure that only in bright summer sunshine are the sun blinds lowered. When the winter sun is out, the sunlight is allowed in, which increases the indoor temperature and represents a considerable saving on their energy bill.
