BASIX & NatHERS for Leppington homes

Leppington is a key part of south-west Sydney’s growth corridor, with master-planned communities such as Emerald Hills and a future town centre around the Leppington rail line. The western-Sydney climate means summer heat management - through glazing, shading and insulation - is central to hitting a 7-star NatHERS rating.

New homes in Leppington need a BASIX certificate and NatHERS assessment as part of any DA or complying development certificate. Leppington straddles the Camden and Liverpool council areas and is being delivered largely through developer-led estates, so lots tend to be compact and orientation is often dictated by the subdivision - all the more reason to get the modelling right before you lodge.

Leppington has the hot summers and cool winters typical of south-west Sydney. East and west-facing glass drives summer heat gain, while ceiling and wall insulation governs winter comfort. We assess each home against the correct local NatHERS climate zone so your rating is accurate for Leppington, not a generic Sydney figure.

What matters when building in Leppington

  • Glazing control and shading on east and west elevations to limit summer heat
  • Lighter roof colours to reduce cooling load on exposed lots
  • Ceiling insulation to R5.0 or better, with appropriate wall insulation
  • Window sizing matched to floor area so you reach 7 stars without over-glazing
  • Whole-of-home compliance for hot water, lighting and solar PV under NCC 2022
