Using Thermal Activation for Energy Efficiency

The Kiwi Precast System is built for energy efficiency, with insulation placed on the exterior of the precast concrete walls. This design allows the concrete to act as a thermal reservoir, using its mass to regulate indoor temperatures.

The concrete absorbs heat during the day and releases it at night, helping maintain stable temperatures inside the building regardless of outdoor conditions. Embedded water lines further enhance this process, circulating heated or cooled water through the structure to provide consistent temperature control. This approach reduces energy consumption and operational costs while creating a comfortable, eco-friendly environment.

Prefabrication for Passive House

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.
