BASIX CERTIFICATE South Nowra

---

This custom designed residential project in South Nowra, NSW involved a new single‑storey home paired with a self‑contained granny flat, designed to deliver functional living, long‑term flexibility, and strong energy performance outcomes.

Assessify provided full BASIX and NatHERS compliance services, ensuring the development met NSW sustainability requirements while supporting efficient construction and cost‑effective design decisions.

Our Scope

• BASIX Certificate (Energy, Water & Thermal Comfort)
• NatHERS thermal performance modelling
• Glazing, insulation, and building fabric optimisation
• Shading and orientation recommendations
• Cost‑efficient compliance pathways tailored to the builder’s specification

Energy & Water Outcomes

• Achieved required NatHERS star rating through efficient building fabric improvements
• Reduced predicted heating and cooling loads through orientation‑led design
• BASIX water targets met using efficient fixtures and rainwater reuse strategies
• Compliance achieved without unnecessary specification upgrades, supporting buildability and cost control

Why This Project Matters

This South Nowra development demonstrates how thoughtful design and targeted modelling can deliver strong compliance outcomes for dual‑occupancy sites. By integrating performance strategies early, the project achieved a smooth BASIX approval process and a more comfortable, efficient home for future occupants
