BASIX & NatHERS for Edmondson Park homes
Edmondson Park is a fast-growing south-west Sydney suburb anchored by master-planned communities such as Frasers Property’s Ed.Square, with a town centre and rail station driving steady new-home and townhouse construction. The western-Sydney climate puts summer heat at the centre of every 7-star NatHERS design.
Whether you are building a detached home, a duplex or a townhouse in Edmondson Park, you will need a BASIX certificate and a NatHERS assessment for your DA or complying development certificate. Lots here are typically compact and part of developer-led releases, so orientation and window layout are often fixed early - making upfront thermal modelling valuable.
Edmondson Park sits in Liverpool City Council and experiences western Sydney’s hot summers and cool winters. West-facing glazing is the main source of summer heat gain, while insulation and sensible glazing ratios carry winter performance. We model each home against the correct local NatHERS climate zone for an accurate Edmondson Park rating.
