Practical, WA-specific research guides covering every aspect of sustainable home building — from passive solar principles to finding the right professionals.
GETTING STARTED
Planning your Sustainable Home
The essential first steps: understanding your block, solar orientation, Perth’s climate, setting a realistic budget, and navigating WA council requirements. Start here before anything else.
DESIGN PRINCIPLES
Passive Solar Design
How orientation, glazing ratios, thermal mass, eave depths, and cross-ventilation work together in Perth’s Mediterranean climate. The science behind homes that stay comfortable without mechanical heating or cooling.
MATERIALS
Eco-Friendly Building Materials
Compare rammed earth, hempcrete, cross-laminated timber, recycled steel, and conventional alternatives. Understand embodied carbon, performance in WA conditions, availability, and cost.
ENERGY PERFORMANCE
Windows, Insulation & Building Envelope
Windows, insulation, building envelope, NatHERS ratings, and how to achieve genuine energy performance — not just compliance.
ELECTRIFICATION
Home Electrification & Renewable Energy
Solar panels, battery storage, heat pumps, induction cooking — the practical guide to going all-electric in Perth’s climate.
WATER & LANDSCAPE
Water Efficiency & Sustainable Landscaping
Rainwater harvesting, greywater recycling, waterwise gardens, and sustainable landscaping for WA’s dry climate.
INDOOR ENVIRONMENT
Home Health & Comfort
Indoor air quality, natural ventilation, thermal comfort, acoustics, and daylighting — designing homes that are genuinely healthy to live in.
RENOVATING & RETROFITTING
Renovation & Retrofitting
Upgrading an existing home’s thermal performance, insulation, glazing, and energy systems — without starting from scratch.
COMPLIANCE & BENCHMARKS
Ratings & Standards
NatHERS, NCC, Green Star, Passive House — understanding the ratings systems and building standards that shape sustainable construction in Australia.
OFF-GRID & REGIONAL POWER
Off-Grid & Hybrid Power Systems
When off-grid makes sense, WAu2019s free Stand-Alone Power System program, and sizing for genuine independence.
CONSTRUCTION METHODS
Prefab & Modular Construction
How prefab, modular and alternative wall systems compare to conventional site-built construction.
FINANCE & INCENTIVES
Rebates & Incentives
Federal and WA state rebates for solar, batteries and electrification: what is currently available and how much you can get.
BUSHFIRE COMPLIANCE
Bushfire Attack Level (BAL) Ratings
What a BAL rating means, how it is assessed, and how it affects design and construction costs in bushfire-prone WA.
FINANCIAL PLANNING
Financial Planning & Green Home Loans
How green home loans work, what qualifies, and a practical framework for budgeting a sustainable build or upgrade.
SMART HOME & TECHNOLOGY
Smart Home & Energy Monitoring
Energy monitoring, automation and CSIP-AUS smart inverters – how to actually use the energy you generate.
