Park 226

So far, most structures using the method 22·26 have been office buildings. Kirchstrasse is our first larger 22·26 housing project – and a statement on energy efficiency and sustainability in residential construction. Even without conventional air-conditioning technology, the buildings maintain year-round, comfortable temperatures between 22 and 26 degrees Celsius – all with consistently good air quality. The key? Solid construction, energy storage capacity, a well-balanced interplay of façade and window surfaces, and software-controlled – but also manually operable – ventilation openings. Heat generated by users, lighting and appliances are factored in as well.
