The U.S. Department of Energy Solar Decathlon® is a collegiate competition, initiated in 2002, that has grown to showcase much more than solar technologies.
10 Contests are the foundation of the Solar Decathlon. It inspires student teams all over the world to design and build highly efficient buildings powered by renewable energy. Important aspects such as affordability, resilience and occupant health are taken into account. The winner among the 18 teams is the one that best combines architectural and technical excellence with innovation.
Urban life in the 21st century is at a turning point. As more and more people are moving into cities, climate problems are becoming more pressing and urban problems must be addressed appropriately. The mission of SDE21»22 calls for urban transformations that take into account social, economic and ecological aspects – focusing on the revitalisation of buildings by adding storeys, extensions and filling gaps. Solutions must go beyond the mere design of architectural drafts, for instance by developing a strategy for urban mobility. The aim is to create a vision for a modern, livable and environmental friendly city of the future.
The Energy Endeavour Foundation and the designated SDE21 Host City Wuppertal are working towards a successful Solar Decathlon Europe 2021»22, in which the international university teams from 11 countries will compete against each other. HFT Stuttgart is one of the 3 participating universities in Baden-Württemberg.
In 2010, a team from HFT Stuttgart participated in the Solar Decathlon Europe in Madrid with great success. The project home+ achieved the third place in the overall ranking and took first places in the categories Engineering & Construction, Solar System and Hot Water and Innovation.
The building for a one- or two-person household was conceived as a compact, highly insulated volume. It was divided into modules, which were arranged at a specific distance from each other. The resulting spaces were used for lighting, ventilation, heating in winter and passive cooling in summer. As a climate-active gap, the so-called energy tower was of particular importance: the interaction of wind and evaporative cooling contributed to a pleasant indoor climate in hot and dry regions such as Madrid.
