School renovations: Quick – affordable – green and healthy

Most school buildings in Europe were built between the 1950s and 1980s Students and teachers spend thousands of hours within them. A renovation of these schools leads to higher learning progress and a better life quality of everyone involved. An innovative and ecological solution for renovations is possible by using prefabricated wooden elements. Because of the prefabrication technologies, construction works on site do not take much time. While these elements provide an inner thermal insulation layer, they can also integrate technologies like solar shading, ventilation systems, photovoltaics and daylight solutions. As shown in this example an 89% reduction of the heating demand was reached while the Co2 emissions where cut by 75% using renewable energy system. Overall the final energy demand was decreased by 77%. The high degree of prefabrication of elements allows renovation of a whole building entirely within the holiday season. Container classes can be avoided. Using these techniques, an old school can accomplish the same specifications as a brand new nearly zero energy building (nZEB). A responsible approach to our environment is one of the biggest issues of our time. Wooden constructions reduce CO2 emissions and ensure climate protection. Together with good indoor climate, natural light and natural materials inside a school, a renovation significantly increases the space quality as well as the well-being of students and teachers. More examples and detailed information about technical and financial solutions of school retrofits can be found on our project website.
