Kiwi Newton specializes in constructing buildings that meet the principles of Passive House design:
Superinsulated envelopes to reduce heat loss
Airtight construction to prevent energy leaks
High-performance glazing for thermal efficiency
Thermal-bridge-free detailing to stop energy loss
Heat recovery ventilation for fresh air without heat loss
The international Passive House (Passivhaus) standard requires strict energy performance metrics:
Space heat demand: max 15 kWh/m² annually or 10 W/m² heating load
Airtightness: pressurization test result of 0.6 ACH at 50 Pa
Primary Energy Demand: max 120 kWh/m² annually
These demanding standards ensure minimal heating and cooling energy usage.
