High-Performance Homes
What the term actually means, and the building systems that make it real.
What is a high-performance home?
A high-performance home is one that has been designed and built to use significantly less energy than a standard home — while delivering superior comfort, air quality and durability. The term covers a spectrum from moderately upgraded construction through to Passive House standard.
What distinguishes genuinely high-performance homes from marketing claims is measurable, verified performance — particularly airtightness and energy demand — rather than just better materials or higher star ratings.
The key systems
Airtight building envelope
Airtightness is the foundation. Without it, insulation is undermined by uncontrolled air movement, ventilation systems can’t function as designed, and the building loses heat through gaps and cracks. Target: ≤3 ACH50 for high-performance, ≤0.6 ACH50 for Passive House.

In an airtight home, MVHR provides the controlled fresh air the occupants need. It recovers heat from outgoing stale air, dramatically reducing the energy cost of ventilation. Essential above 3 ACH50 airtightness.
Learn more →Heat pump hot water
Hot water is typically the second largest energy load in a home after space heating. Heat pump hot water reduces this load by 60–75% compared to a direct electric element, and pairs well with solar PV.
Learn more →Continuous, high-performance insulation
Thick insulation — particularly when continuous and free of thermal bridges — dramatically reduces heat flow through walls, roof and floor. The goal is a building envelope with consistent, predictable thermal resistance.
High-performance glazing
Double or triple glazing with low-e coatings and thermally broken frames reduces radiant heat loss in winter and solar heat gain in summer — eliminating cold spots and hot zones that degrade comfort.
Why it matters in South Australia
South Australia has some of the highest electricity prices in the country. A high-performance home significantly reduces dependence on grid electricity — and when combined with solar PV, can approach net-zero or net-positive energy performance.
The SA climate — hot dry summers and cool winters — is well-suited to high-performance building. Passive cooling strategies, thermal mass, shading and MVHR with summer bypass can maintain comfortable indoor temperatures with minimal active cooling.
