— 01 Environmental approach

Environmental
engineering, by hand.

With extensive experience in both structural and technological systems — electrical, water, heating, photovoltaic and solar thermal — Ibba Construction provides expert guidance on environmentally responsible design and construction. Performance is engineered into the structure from day one, not tacked on at the end.

— 02 Technical commitments

Six systems,
engineered in.

Standard on every custom build. Specifications are tuned to climate zone, orientation and the way the home will actually be used.

Passive solar orientation

Building axis, eave depth and glazing area calibrated to the WA solar path — winter sun in, summer sun out.

Aligned within ±5° of true north

Double glazing

Argon-filled low-e units on all habitable rooms — typically halving the heat loss of single-glazed windows.

U-value ≤ 1.6 · SHGC tuned per elevation

Insulation

Full-perimeter insulation: walls, ceiling, suspended floors. Air-sealing detailed at every penetration.

R5.0 ceiling · R2.7 walls minimum

Photovoltaic systems

Roof-mounted PV sized to cover annual self-consumption. Tier-1 panels, hybrid inverter and battery-ready.

8–12 kWp typical · CEC accredited install

Solar-thermal hot water

Roof-mounted thermal collectors with gas or heat-pump backup. Hot water for the household from sunlight.

315L tank · 4–5 kWh/day yield

Material sourcing

Premium Perth-quality materials and Italian craftsmanship — every material has a traceable origin where feasible.

Local WA supply chain preferred

From sketch
to roof line.

Selected installations from recent builds. Photovoltaic arrays, solar-thermal collectors and the everyday detailing that lets a home run efficiently for decades.
