A BASIX Assessment is required for residential developments in New South Wales to demonstrate compliance with the state’s sustainability targets for energy, water efficiency, and thermal comfort.
We provide accurate and council-ready BASIX Certificates to support your DA (Development Application) or CDC (Complying Development Certificate) submission.
Our assessments ensure your project meets BASIX requirements while keeping the design practical, cost-effective, and aligned with your architectural intent.
We evaluate your project across three core performance areas:
| Category | What We Review |
|---|---|
| Thermal Comfort | Building fabric, insulation levels, glazing, shading, passive design & NatHERS modelling |
| Energy Efficiency | Lighting performance, hot water systems, heating/cooling equipment, PV solar potential |
| Water Efficiency | Fixture ratings, landscaping, rainwater storage & reuse opportunities |
We focus on achieving compliance without unnecessary specification upgrades or design compromises.
