Switzerland's Solar-Powered Islas Office is an Energy-Storing Battery Building
The Islas Office Building is located in Samedan between the Inn River and Kantonal Road. Mierta & Kurt Lazzarini Architekten took inspiration for the building’s facade from the nearby riverbed and the stepped hillsides in the distance. The wavy rusty iron sheet and the glass facade reflect the surroundings and the ever-changing light. The four-story structure includes a central atrium and circulation core for each of the four businesses within: migrolino-store, a dental surgery, a beauty clinic and an architecture office.
A clever energy-saving system is integrated throughout the entire building, and intelligent controls manage all the equipment. On the roof, a large solar photovoltaic system soaks up the sun’s energy, which is stored in water tanks under the building. Similarly, each level features concrete floors, which absorb the sun’s heat during the day and transfer that heat to the interior of the building for use later in the night. Also, rejected heat from the migrolino store’s refrigerator system is moved throughout the building for heating elsewhere. Thanks to these systems, very little additional heating is needed during the cooler months.
