A note for our project teams, property owners and developers who are working hard to transform our built environment with environmental sustainability as a priority.
With the annual GBCSA Convention in a few months, and the end of the year in sight, it’s important that project teams involved in certifying projects with GBCSA are aware of key dates that may affect their planning.
- GBCSA’s annual convention takes place 11-13 November 2025. During this time, we will unfortunately not be available to process certifications or payments. Should you wish to have projects included as entrants into the 2025 convention awards, they are required to be certified on or before 1 July 2025.
- Festive season closure: This is a reminder of GBCSA’s annual closure for the festive season from 19 December 2025 to 7 January 2026. During this time, we will not be available to process certifications or payments. Should you wish to get projects registered and/or certified in 2025, and benefit from the current rates, we urge you to get your projects registered in good time. Please consider the full payment process when factoring in the time required to finish the invoicing and payment requirements of your company.
In general, please consider the entire certification process required for Round 1 and Round 2 within your project programme. Green Star APs and/or EDGE Experts and Auditors are responsible for communicating this to project owners and guiding projects teams by taking these timelines into consideration.
Please take note of the following timelines in relation to Convention:
GREEN STAR, NET ZERO & EWP CERTIFICATION
The entire GBCSA assessment timeline is 12 weeks – seven weeks for Round 1 and five weeks for Round 2.

ACTIVATION AND PAYMENTS
- If there is a project that you would like to be fully activated before the GBCSA office shutdown, please ensure that a signed certification agreement and payment is received by 10 December 2025.
- If you would like your project to benefit from 2025 fees, please ensure the GBCSA receives payment and that the signed certification agreement is uploaded by 31 December 2025. Full activation, however, will happen once the GBCSA team is back from the end of year shut down.
- For bulk registrations, please make certain of your account procedures for the invoicing and payments process when seeking to benefit from 2025 fees – this process can take between 2 – 4 weeks from project registration (for Green Star via the Certification Engine or manually and EDGE via the EDGE App) to tax invoice, to make payment runs. \
- The GBCSA team will not be contactable from 12h00 on 12 December 2025.
We expect that 2025 could be an excellent year for Green Star, EDGE, Net Zero and EWP certifications as building owners and occupants continue to reap the health, environmental and financial rewards delivered by certified green buildings. We look forward to helping professional teams meet their green goals this year.
Thank you for your support.
