Passivhaus (German terminology)
Passivhaus (or Passive House) is a rigorous standard for energy-efficient building design, originating in Germany. It focuses on minimizing energy use for heating and cooling through superior insulation, airtight construction, high-performance windows, and ventilation with heat recovery. This design reduces energy consumption by maintaining a steady indoor temperature, regardless of outside weather. As a result, Passivhaus buildings are highly comfortable, environmentally sustainable, and cost-effective over time, requiring little active energy input. The approach emphasizes quality craftsmanship and precise engineering to create healthy, low-energy structures that significantly cut carbon emissions.
