Passive House
The leading standard in energy saving in buildings worldwide
The energy saving for heating amounts to over 75% in comparison with the legally
prescribed building standards
Achieve this enormous energy conservation through the use of special energy
efficient building elements and ventilation techniques
Zero Energy House
Passive House + Domestic production of energy
It’s not meaning that no energy is consumed in buildings
Minimize active technical inputs is needed by maximizing passive technology
≤ 0.15 W/ ㎡K Wall Transmission
≤ 0.8 W/ ㎡K Window Transmission
n50 ≤ 0.6/h Airtightness
≥ 75% Heat recovery efficiency (Ventilation)
