What does a BASIX assessment include?

A BASIX assessment reviews your residential design to ensure it meets water and energy efficiency targets in New South Wales. It looks at fixtures, appliances, orientation and building materials to assess performance.

Short answer

The assessment covers energy use, water savings and thermal comfort based on your building plans.

Full answer

The BASIX assessment involves entering design specifications into the official online tool. It evaluates three key areas:

• Energy: heating, cooling, hot water, lighting, ventilation and renewables
• Water: tapware, rainwater tanks, toilets, irrigation and landscaping
• Thermal comfort: insulation, glazing, orientation and ventilation strategy

The assessment uses climate data and simulation tools to measure performance and confirm if your design meets targets.

Why this matters

This process helps reduce future energy bills and makes homes more liveable and environmentally responsible.
