Queensland Residential Energy Compliance

Queensland allows eligible outdoor living areas to contribute nominal credits towards the current 7 Star energy-equivalence requirement. This guide explains the 0.5-star and 1-star pathways, what appears on the NatHERS certificate and how the rules differ between houses and apartments.

 

Queensland’s residential energy-efficiency pathway contains an important variation that can cause confusion for builders, designers and homeowners.

A new home may sometimes comply with Queensland’s 7 Star energy-equivalence requirement even where the modelled NatHERS building-shell rating is below 7 stars.

This may be possible where the design includes an eligible outdoor living area and satisfies the relevant conditions under Queensland Development Code Mandatory Part 4.1 — Sustainable Buildings, commonly referred to as QDC MP 4.1.

The pathway is sometimes still described informally as a “6 Star dispensation credit”. That language reflects the former 6 Star benchmark and is no longer the clearest description of the current requirement.

Preferred Current Description

A nominal outdoor living area credit used to demonstrate equivalence with Queensland’s 7 Star regulatory standard.

In Brief

How the Queensland Pathway Works

For an eligible Class 1 house or townhouse, Queensland may allow one of the following pathways:

Modelled Result

7.0 Stars

The dwelling reaches the benchmark through its modelled thermal performance without an outdoor living area credit.

Equivalence Pathway

6.5 + 0.5

A compliant outdoor living area contributes a nominal 0.5-star credit.

Equivalence Pathway

6.0 + 1.0

A compliant outdoor living area with the required ceiling-fan provision contributes a nominal 1-star credit.

The credit supports the Queensland regulatory pathway. It does not alter the modelled star rating shown on the NatHERS Universal Certificate. The applicable Whole of Home requirement must also be assessed separately.

Regulatory Context

What Is QDC MP 4.1?

QDC MP 4.1 is the Queensland-specific code covering several sustainable-building requirements.

The current version supports Queensland’s implementation of the NCC 2022 residential energy-efficiency provisions. The updated requirements commenced in Queensland on 1 May 2024.

For new residential dwellings, the framework includes two distinct performance components:

1. Building-shell performance
The modelled thermal performance of the dwelling fabric.

2. Whole of Home performance
The wider energy budget associated with fixed appliances, equipment and on-site renewable energy where relevant.

Queensland retains an optional outdoor living area credit within this pathway in recognition of the role that covered and ventilated outdoor spaces can play in the state’s housing design and climate response.

Technical Distinction

Why Does Queensland Call It Energy Equivalence?

A NatHERS assessment produces a modelled thermal-performance rating between 0 and 10 stars. The rating reflects the predicted heating and cooling demand associated with the dwelling design.

Roof, walls, floors and ceilings
Insulation and construction
Windows and glazing
Orientation and shading
Layout and zoning
Local climate

Queensland’s outdoor living area credit sits outside that modelled NatHERS result. It is a nominal regulatory credit applied when determining whether the project demonstrates an outcome equivalent to the required Queensland standard.

A home that models at 6 stars and receives a nominal 1-star outdoor living area credit has not achieved a 7-star NatHERS software rating.

It has a 6-star NatHERS building-shell rating with a Queensland credit supporting equivalence to the 7 Star regulatory requirement.

Outdoor Living Credit

The 0.5-Star Outdoor Living Area Credit

For a Class 1 house or townhouse, an outdoor living area may contribute a nominal 0.5-star credit where it satisfies the applicable QDC requirements.

The area generally needs to:

  • Be fully covered.
  • Connect directly to an indoor living area.
  • Provide at least 12 square metres of floor area.
  • Measure at least 2.5 metres in every direction.
  • Have an impervious roof.
  • Provide roof insulation with an R-value of at least R1.5.
  • Have at least two sides open or capable of being readily opened.

Where all relevant conditions are met, a home with a modelled 6.5-star building-shell rating may be able to demonstrate equivalence with Queensland’s 7 Star requirement.

Outdoor Living and Fan Credit

The 1-Star Outdoor Living Area and Ceiling-Fan Credit

A nominal 1-star credit may be available where the outdoor living area satisfies the underlying requirements and includes the necessary permanently installed ceiling-fan provision.

Fan requirements

The ceiling fan generally needs a speed controller and a blade rotation diameter of at least 900 millimetres.

Coverage requirements

Fan size and the number of fans must provide suitable coverage for the outdoor living area.

A fan with a blade rotation diameter below 1,200 millimetres may generally serve no more than 15 square metres.

A fan with a blade rotation diameter of at least 1,200 millimetres may generally serve no more than 25 square metres.

A larger outdoor living area may therefore require more than one fan. Where all applicable conditions are met, a Class 1 dwelling with a modelled 6-star building-shell rating may be able to use the nominal 1-star credit to demonstrate equivalence with Queensland’s 7 Star requirement.

Certificate Outcome

Does the NatHERS Certificate Show the Credit?

The NatHERS Universal Certificate records the dwelling’s modelled NatHERS result. The outdoor living area credit does not increase that modelled rating.

NatHERS Certificate

Shows the actual modelled rating, such as 6 stars.

Queensland Compliance

Documents the nominal credit separately as part of the energy-equivalence pathway.

A project should therefore not be described as having achieved a 7-star NatHERS rating unless the NatHERS certificate itself shows 7 stars.

Apartment Projects

How Does the Pathway Work for Class 2 Apartments?

QDC MP 4.1 also allows outdoor living area credits to be considered for eligible sole-occupancy units in Class 2 apartment buildings. However, the compliance structure differs from the pathway for a single Class 1 dwelling.

A new Class 2 residential building generally needs to achieve an average 7-star energy-equivalence rating across the relevant units.

No individual unit may fall below the applicable minimum rating.

For units, the nominal credit is used only when calculating the building’s average rating for compliance. It does not increase the NatHERS rating shown for an individual apartment.

Because Class 2 projects involve average ratings, individual-unit minimums and building-wide calculations, the pathway should be reviewed at project level rather than assumed from a single apartment layout.

Separate Energy Requirement

Does the Credit Replace Whole of Home?

No. The outdoor living area credit relates to the thermal building-shell component of the Queensland pathway.

Whole of Home is a separate assessment of the dwelling’s broader operational-energy budget, including relevant systems such as heating and cooling equipment, hot water, lighting, cooking, pool and spa equipment, solar photovoltaic systems and batteries where included.

A project using an outdoor living area credit must still satisfy its applicable Whole of Home requirement.

Previous Queensland Pathway

What Happened to the Former Solar PV Credit?

Under the former Queensland pathway, a solar photovoltaic system could provide a nominal 1-star credit.

That separate PV credit ceased on 30 April 2024. From 1 May 2024, solar PV is considered through the Whole of Home energy budget rather than as a separate nominal building-shell star credit.

Older project documents, articles or consultant terminology may still refer to a Queensland solar credit. That information should not be assumed to describe the current pathway.

Current Terminology

Is This Still a “6 Star Dispensation”?

Some project teams continue to use expressions such as “6 Star dispensation”, “QDC dispensation credit” or “6 Star plus 1 Star credit”.

These phrases may identify the historical concept, but they can also create the incorrect impression that Queensland still has a general 6 Star standard.

Preferred Term

Queensland QDC MP 4.1 outdoor living area credit.

Project Coordination

When Should the Credit Pathway Be Confirmed?

The pathway should be considered early enough for the outdoor living area to be coordinated with the architectural, energy and approval documentation.

Architectural plans and dimensions
Roof construction and insulation
Connection to internal living areas
Open or openable sides
Ceiling-fan size and coverage
NatHERS and Whole of Home modelling

A verandah, balcony, patio or terrace should not be assumed to qualify simply because it is labelled as an outdoor living area on the plans. Its dimensions, enclosure, roof, insulation, relationship to the living space and fan provision all need to be checked against the applicable criteria.

 

Frequently Asked Questions

Queensland QDC MP 4.1 FAQs

Can a Queensland house comply with a 6-star NatHERS rating?

Potentially, but only where the dwelling satisfies the requirements for the nominal 1-star outdoor living area credit and all other applicable compliance requirements. The NatHERS certificate will still show the modelled 6-star result.

Can a 6.5-star house use the smaller credit?

A dwelling with a 6.5-star modelled rating may be able to use the nominal 0.5-star outdoor living area credit where the relevant criteria are satisfied.

Does any covered patio qualify?

No. The outdoor living area must satisfy the applicable requirements for size, dimensions, connection, roof construction, insulation and open sides. The 1-star pathway also requires compliant ceiling-fan coverage.

Can the credit take a house below 6 stars?

No. A Class 1 house using the optional credit pathway still requires a minimum 6-star modelled building-shell rating.

Can the credit be used to advertise an 8-star home?

No. The credit is used for regulatory compliance and does not increase the NatHERS software rating. A 7-star NatHERS home with a nominal 1-star credit does not become an 8-star NatHERS home.

Do apartments use the credit in the same way as houses?

Not exactly. For Class 2 buildings, the credit contributes to the building’s average energy-equivalence calculation and does not increase the individual NatHERS rating of a sole-occupancy unit.
