Question 1

Who is the Green Star Performance certification best suited for?

Accepted Answer

Green Star Performance is best suited for owners and managers of existing commercial buildings in Australia — including offices, retail centres, universities, and hospitals — who want to benchmark, improve, and publicly demonstrate the operational sustainability of their assets. It is particularly valuable for property companies, REITs, and institutional investors seeking credible third-party validation of environmental performance to meet ESG reporting obligations or tenant expectations.

Question 2

What are the renewal requirements for the Green Star Performance?

Accepted Answer

Green Star Performance certifications are valid for three years, after which buildings must re-submit updated operational performance data to maintain their rating. Renewal involves a new assessment cycle using 12 months of current data, allowing the rating to reflect ongoing performance improvements or changes. Renewal fees apply and are based on building size and type.

Question 3

What continuing education is required for the Green Star Performance?

Accepted Answer

No formal CPE/CEU requirements are mandated for building owners seeking certification. However, Green Star Accredited Professionals (AP) who assist with submissions are required to maintain their own continuing professional development through GBCA's AP program.

Question 4

What evidence is required for the Green Star Performance?

Accepted Answer

Applicants must submit 12 months of operational performance data across all applicable credit categories, including energy consumption records, water usage data, waste diversion data, indoor environment quality measurements, and management documentation. Evidence is compiled into a formal submission reviewed by GBCA-appointed independent assessors. Supporting documentation such as utility bills, metering data, occupant surveys, and maintenance records is typically required. A site audit may be conducted to verify submitted data.

Question 5

Who should NOT pursue the Green Star Performance?

Accepted Answer

If your building is still in the design or construction phase, Green Star Design & As Built is the more appropriate rating tool. Organisations seeking a lightweight or low-cost sustainability acknowledgement may find the documentation and audit requirements of Green Star Performance resource-intensive.

Question 6

What are alternatives to the Green Star Performance?

Accepted Answer

Alternative certifications include: NABERS Energy for Offices, BREEAM In-Use, LEED Operations and Maintenance (O+M), WELL Building Standard, Living Building Challenge.

Question 7

What is the salary impact of the Green Star Performance?

Accepted Answer

Green Star Performance certification primarily benefits building asset values and operating cost profiles rather than individual salaries. Certified buildings typically command rental premiums of 5–10% and higher occupancy rates compared to non-rated peers, according to Australian property market research. Facility managers and sustainability consultants with Green Star project experience are generally more competitive in the Australian property market.
