Pillars

The Six Pillars of a Passive Dwelling

Pillar 1 — High-Performance Insulation

Premium-rated insulation is installed across the floor, walls and ceiling, creating an unbroken thermal envelope that keeps warmth inside during winter and blocks heat gain in summer

Pillar 2 — Airtight Building Envelope

Every junction, penetration and service entry point is sealed to prevent heated or cooled air from escaping through gaps in the external skin of the building.

Pillar 3 — High-Performance Glazing

Windows and sliding doors are specified with low-E coatings and insulated frames that maximise useful solar warmth in cooler months while minimising unwanted heat transfer year-round.

Pillar 4 — Elimination of Thermal Bridges

A thermal bridge occurs wherever there is an uninsulated break in the building envelope — for example, a steel lintel or an un-wrapped stud. Removing or mitigating these weak points stops heat from conducting straight through the structure.

Pillar 5 — Correct Building Orientation

The granny flat is positioned on the block to capture low-angle winter sun for passive heating while using eaves, louvres or deciduous planting to shade the interior during the hotter months.

Pillar 6 — Heat Recovery Ventilation (HRV)

An HRV unit extracts stale indoor air while recovering most of its warmth and transferring that energy to the fresh air being drawn in, keeping the interior ventilated without losing temperature control.
