The Szencorp Building’s Ratings
In Australia, there are three separate star rating systems. The Szencorp achieved the maximum star rating under each of the Australian rating systems.

NABERS Water: 5 Stars
5 stars which is the maximum achievable and is equal to “best building performance”.

NABERS Energy: 5 Stars (formerly ABGR)
5 stars is the maximum achieveable and indicates industry best practice.

Green Star: 6 Stars (Green Star Office Design v1 Certification)
6 Stars is the maximum rating achievable under Green Star Office Design Certification from the Green Building Council of Australia and is considered to be ‘world leadership’ standard.

To achieve a 6 Green Star rating a building must score a minimum of 75 points. The Szencorp Building obtained a score of 83. Read the GBCA’s case study on 40 Albert Road here.

How do the rating systems work?
NABERS Energy and Water
NABERS is a voluntary, performance-based environmental rating system for office premises. NABERS ratings for offices include NABERS Energy (previously ABGR), and NABERS Water.

NABERS Water measures the water consumption of an office building on a scale of one to five stars, reflecting the performance of the building relative to the market, from least efficient (one star) to best practice (five stars). Two and a half stars is the current market average. NABERS Energy does the same, but with energy use (including gas, electricity, coal and oil).

Unlike rating systems which are based on a building’s design, NABERS reflects the way energy and water is managed. NABERS is a national initiative managed by the NSW Department of Environment and Climate Change and rates a building on the basis of its measured operational impacts on the environment.

Green Star
The Green Building Council of Australia (GBCA) launched the Green Star environmental rating system for buildings in 2003. Green Star rating tools are a design-based suite of tools that aim to help the property industry improve the environmental performance of buildings, increase occupant health and productivity, and achieve cost savings, while advancing innovation in sustainable building practices.
The Green Building Council of Australia is a national, not-for-profit organisation. For more information on the GBCA and on Green Star go to
