Office Buildings

A NABERS Energy rating measures the energy efficiency of your office building. It includes the Renewable Energy Indicator, which shows what percentage of your building's energy has come from renewable sources. 

You may choose to rate any of the following spaces:

• Base building – to measure the energy performance of a building’s central services like heating and cooling systems, lifts and lobby lighting.
• Tenancy – to measure the energy performance of a specific tenancy within the building. It considers factors including a tenancy’s lighting and power.
• Whole building – this rates both the base building and tenant occupied space. This is most useful when a single tenant occupies the whole building.

Team up with tenants and save

Co-Assess makes it easier for base buildings and tenancies to be rated together, with each receiving their own NABERS Energy rating.

A NABERS Water rating measures the amount of water used and recycled in your office building. It provides a clear picture of your building’s water performance, helping you understand how efficiently water is being used and identify opportunities to reduce consumption, save costs and support your sustainability goals.

A NABERS Waste rating measures how well your building manages waste generation, recycling, resource recovery and supply chain management. The rating is calculated on the NABERS Waste Platform, which can be used to generate waste and recycling reports. 

You may choose to rate any of the following spaces:

• Base building – to measure only the waste contracted by the building owner, providing insights into the management of the building.
• Whole building – measure any waste produced in the building, where it can be reliably measured. This includes waste from both shared spaces and tenancies, suiting buildings with highly engaged tenants.

A NABERS Indoor Environment rating measures the indoor environment quality of a building, based on factors that affect people's cognitive performance, satisfaction and productivity. It considers the indoor air quality, lighting quality, temperature, thermal comfort and acoustic quality of a building. 

You may choose to rate any of the following spaces:

• Base building – for building owners and managers who generally control and maintain thermal services, air systems and building cleaning services.
• Tenancy – for building occupants who generally control and manage the design and materials used for their office fit-out and lighting. Some tenants also have control over indoor air quality too.
• Whole building – for organisations that both manage and occupy their office space, or when a single tenant occupies an entire building.

For office buildings that achieve a minimum of 4 stars for NABERS Energy, NABERS offers a pathway to achieve Climate Active Carbon Neutral Certification.

Measure the upfront embodied carbon of your new office build or partial rebuild with a NABERS Embodied Carbon rating. This tool is a certified measure of material, transport and construction-related emissions

Commit to design, build and commission an office building to achieve a specific Energy rating with a NABERS Commitment Agreement.

If you’re building or refurbishing an office building, you can commit to obtaining a NABERS rating once it becomes operational with an Agreement to Rate.
