NABERS measures the environmental performance of buildings, developments, homes and tenancies. The Embodied Emissions Reporting helps measure the carbon released during the process of building a home, development or tenancy and its total impact on the surrounding environment.

To understand whether you need an Embodied Emissions report, you first need to understand what embodied carbon/emissions are.
Embodied carbon refers to the carbon emissions released throughout the entire process of constructing a building. This includes the extraction of raw materials, the manufacturing and refining of materials, transportation, installation, and even the disposal of old supplies. All of these stages contribute to the production of embodied carbon emissions.
As of 1 October 2023, NSW has adopted NABER's methodology of capturing the exact quantities of key materials used in a project and listing their Embodied Emissions.

How is the Embodied Emissions Report assessed?

Accredited NABERS Assessors audit the architectural and engineering documentation package and extract quantities of materials. This is then curated and entered into the Embodied Emission Material form. The proposed building is broken down into the following four categories:

1. Structure

2. Envelop

3. Permanent internal walls and doors

4. Services

5. External works

Whenever possible, the direct cost of materials to construct the building. and permanent elements of the proposed building will be recorded. Labour or equipments should not be accounted for.

The catchment for materials recorded should cover at least 80% of the total bill of materials. 

Below is a step-by-step illustration of how the embodied energy of materials are quantified and reported in Worksheet 2 of the  Embodied Emissions Materials Form.

Step 1

Our technicians model the proposed development.

Step 2

The proposed development will then be broken down into Structure/Envelop/Permanent Walls and Doors/External Works.

Concrete elements 492-1

Walls 492

Fig 4.  Permanent Internal walls ( in square meters) and doors/windows (quantity in numbers)

Step 3

The quantities of materials from our model will then be entered into the corresponding section in the Embodied Emissions Material Form.

As outlined by the NSW SEPP all new residential and non-residential applicants from 1 October 2023 will be required to disclose the quantities of materials and associated embodied emissions when applying for a development application and a construction certificate.
An Embodied Emissions Report is now required in NSW for all non-residential developments. 
Residential projects can refer to BASIX, where a new Material Index has been introduced to calculate and report on embodied emissions.

Costing and Time Commitments

Since the process of conducting an Embodied Emissions report is quite thorough and varies on a project-by-project basis, the cost of conducting the assessment can also vary greatly. Depending on the size and complexity of the project, we recommend that you contact us and obtain a quote. 

As for the time it takes to conduct an Embodied Emissions Report, our turnaround will typically be between 3-10 business days. In light of this, if you have a deadline, let us know and we will make arrangements to meet it.

To obtain an Embodied Emissions Report, please send in your plans for quoting and if you are satisfied with the quote, we will proceed and produce a draft report promptly. Once the draft is approved and payment is received, we will gladly issue a final certification for the project. 




Embodied Emissions Report FAQ's

  • What is an Embodied Emissions Report?

    An Embodied Emissions Report outlines the quantities of key materials and associated embodied emissions throughout the entire process of constructing a building.

  • When is an Embodied Emissions Report required?

    As of 1 October 2023, all new non-residential developments are required to submit an Embodied Emissions Report at the Development Application and Construction Certificate stages.

    Residential developments can opt-in for a materials index report within the BASIX.

  • What is the cost of an Embodied Emissions Report?

    The cost of an Embodied Emissions report can range between 2-4.5k depending on the size of your project.

  • How are Embodied Emissions reported?

    For residential developments, a new Material Index was introduced by the State in the Building Sustainability Index (BASIX) to calculate and report the embodied emissions of construction materials in new developments.

    For all non-residential developments, a NABERS Embodied Emissions Material Form must be completed, with material quantities (and later embodied emissions) to be calculated at the development application stage and again at the construction certificate stage. The form is an interim reporting tool until the NABERS Embodied Emissions Framework and related online tools are released in mid-2024.
