  • 2. Passive House | Passivhaus ! TM ! “A rigorous, voluntary building energy standard focusing on highest energy efficiency and quality of life at low operating cost.” ! ! ! The Passive House Standard is the most rigorous building energy standard in the world. Consultants, projects or building components that have obtained the right to carry the logo have committed themselves to design excellence and the Passive House energy performance criteria.
