BASIX & NatHERS assessments in Bradfield

BASIX & NatHERS for Bradfield homes

Bradfield is the brand-new city taking shape in the Western Sydney Aerotropolis beside the new airport, with thousands of new homes, duplexes and townhouses to come. Every new dwelling needs a BASIX certificate and 7-star NatHERS rating, and the hot western Sydney climate makes summer heat the priority.

New homes and duplexes in Bradfield need a BASIX certificate and NatHERS assessment for the DA or complying development certificate. As a planned city with design controls, lots come with set orientations, so early thermal modelling helps you reach 7 stars while meeting the masterplan guidelines.

Bradfield sits in the hot western Sydney climate zone, where summer afternoons regularly push past 35 degrees. We focus on shading, eaves, light-coloured roofs and well-placed glazing to keep cooling loads down, balanced against winter solar access.

What matters when building in Bradfield

• External shading and eaves to cut harsh western Sydney summer heat
• Light-coloured roofing and high insulation to reduce cooling demand
