An international ultra-low-energy building standard based on continuous insulation, airtightness, absence of thermal bridges and heat-recovery ventilation.
Definition
Passivhaus sets numbers, not intentions: heating demand below 15 kWh/m²·year and airtightness verified by blower door test.
For retrofits of existing homes we work to the EnerPHit criterion, adapted to protected buildings where the façade cannot be touched.
