In a passive house, the annual heating requirement must not exceed 15 kilowatt hours per square meter. This corresponds to a heating oil equivalent of about 1.5 liters of heating oil consumption per square meter of living space per year. The focus of energy conservation in a passive house is on reducing energy losses through walls, windows and ceilings. The special energy efficiency of this demanding building standard is usually achieved through the thermal insulation of the building envelope. In the case of the concrete oasis by Gruber und Popp Architekten BDA, the passive house standard was achieved without an additional thermal insulation layer. The walls made of infralight concrete support and insulate at the same time. From the point of view of energy efficiency and sustainability, infralight concrete offers further advantageous properties: No thermal bridges are created at connections of windows or cantilevered components such as canopies and balconies. The infralight concrete ILC 700 used here has further improved thermal insulation properties compared with previous infralight concrete buildings. The concrete oasis by Gruber + Popp Architekten BDA is the first project for a public client in which infralight concrete was used. For the first time, approval was granted on a case-by-case basis for a public building. Even at the end of the building life cycle, mineral infralight concrete walls offer great advantages in terms of recyclability.
