Concept 22/26, a High Performance Office Building Without Active Heating, Cooling and Ventilation Systems
Abstract
The introduced building concept goes beyond the conventional high performance building discussion by introducing an office building without any active systems for heating, cooling and ventilation. The building is accomplished in July 2013 and is located in the cold climate of Austria. The intelligent control of the building façade is the heart of the innovative building energy concept. It controls automated natural ventilation openings by using demand optimized automation strategies. Results of the first two years of building operation are demonstrating that the comfort level is acceptable in all seasons and that there are no complaints from beside the occupants. The exemplary realized building project demonstrates how innovative building automation technology can be used to reduce the total energy demand for building operation in a cold climate. Its technology can be used in other climate regions as an innovative hybrid ventilation concept.
