Swiss Alpine Hut Powered by the Sun

The Monte Rosa Hut above Zermatt, Switzerland, is nicknamed "Mountain Crystal". The innovative building generates over 90 percent of its own energy and will serve the Swiss Federal Technical University in Zurich as an on-going research project in power and building service engineering. 2,883 meters above sea level, the New Monte Rosa Hut is currently the most complex wooden construction in Switzerland. Covered in a shimmering silver aluminum shell and with a photovoltaic system integrated in the southern facade, it generates its own power and is expected to be at least 90 percent energy self-sufficient. Solar collectors installed in the grounds generate solar heat, which provides warm water and heats the ventilation system's supply air to control the temperature in the rooms. In the few months of the year where the ice melts, the water is collected and stored in a cavern to provide the guests with flush toilets and four hot showers. A bacteria-based microfiltration system cleans the sewage; the graywater is then reused to flush the toilet and for washing. See more images at SOLARIPEDIA.com
