Energy Rating Requirements in Tasmania
Everything you need to know about energy compliance, minimum star ratings, and how to connect with accredited ESD consultants across Tasmania.
Overview
Tasmania has adopted the National Construction Code (NCC) 2022 energy efficiency provisions, which set a minimum 6-star NatHERS energy rating for new residential buildings. Whether you are building a new home, undertaking a major renovation, or developing a multi-unit residential project in Tasmania, understanding the state's specific energy compliance requirements is essential to obtaining your building approval.
Energy ratings measure how well a building's thermal shell (walls, roof, windows, insulation, and floor) performs in the local climate. A higher star rating means less energy is needed for heating and cooling, translating into lower utility bills and improved occupant comfort. In Tasmania, meeting the 6-star benchmark ensures your building aligns with Australia's trajectory toward net-zero emissions by 2050.
Tasmania has deferred adoption of 7-star requirements. Currently 6-star minimum applies.
Key Legislation
Energy efficiency requirements in Tasmania are governed by the Building Act 2016, working in conjunction with the National Construction Code (NCC). The NCC sets the baseline performance standards, while state-level legislation and regulations may impose additional requirements or alternative compliance pathways.
For residential buildings (NCC Volume 2, Class 1 and Class 2 buildings), the primary compliance pathway involves achieving the minimum NatHERS star rating through an accredited energy assessment. Commercial buildings (NCC Volume 1, Class 3 through 9) must comply with Section J energy efficiency provisions or demonstrate equivalent performance through a JV3 verification method.
Minimum Star Rating: 6 Stars
Tasmania requires a minimum 6-star NatHERS energy rating for all new residential construction and major renovations subject to building approval. This is assessed using accredited NatHERS software tools such as FirstRate5, AccuRate, or BERS Pro, depending on the climate zone and building type.
The star rating is assessed on a scale of 0 to 10, where 10 stars represents a building that requires virtually no artificial heating or cooling to maintain comfortable temperatures year-round. Achieving 6 stars requires careful consideration of building orientation, glazing specifications, insulation levels, thermal mass, and ventilation design.
An accredited NatHERS assessor evaluates your building plans and produces a certificate confirming compliance. This certificate is a mandatory document for your building approval application in Tasmania. We connect you with accredited consultants who specialise in Tasmania's climate zones and compliance requirements.
State-Specific Programs
Tasmania follows the National Construction Code without additional state-specific energy programs. However, local councils may still impose supplementary requirements. Working with a local consultant ensures you meet every applicable standard.
Residential and Commercial Compliance
Residential projects in Tasmania typically require a NatHERS assessment to demonstrate compliance with the minimum 6-star energy rating. For commercial buildings, the compliance pathway involves Section J of the NCC, which covers the building fabric, glazing, air conditioning, lighting, and other energy-using systems. A JV3 assessment offers an alternative verification method using thermal simulation modelling.
Regardless of your building type, our network of accredited consultants across Tasmania can guide you through the right compliance pathway for your project.
