This is an in-person or online course (Green Star Advanced). Participants must have completed the Green Star Fundamentals course (formerly Green Star Practitioner) to attend.

This course is targeted at those who wish to make Green Star project submissions to the New Zealand Green Building Council. Generally, potential GSAPs will have professional qualifications in related industries such as engineering, building science, quantity surveying, architecture, project management or similar professional expertise. However other related experience and skills may be acceptable. If you are uncertain whether your background will be appropriate please contact us.

Green Star Fundamentals is the first entry level course, after which people can take the Green Star Advanced course. By completing this course, they automatically become a Green Star Associate, which they can upgrade to a Green Star Accredited Professional (GSAP) accreditation by taking the exam. The accreditation showcases in-depth knowledge of Green Star and is perfect for industry professionals who intend to act as the core member of a Green Star project team and collate and manage Green Star project submissions.

Green Star Accredited Professionals (often referred to as GSAPs) have the skills to work on projects targeting Green Star ratings and are qualified to make high-quality submissions for certification. It provides an in-depth knowledge of the Green Star Design & As Built and Green Star Interiors tool.

Green Star Accredited Energy Modeller

Accredited Energy Modellers are experts in energy modelling and have been recognised by the NZGBC as leading professionals.

Accreditation is through application only, with professionals selected based on the quality of their energy modelling reports, and the modeller’s ability to explain their assumptions, rather than the number of models submitted. 

Accredited Energy modellers can issue Producer Statements for Green Star submissions, in lieu of a full energy report.

Upon receipt of the initial application email the NZGBC will generate an invoice for the application fee and email this back to the applicant. Upon receipt of the application fee ($350 excl. GST) the NZGBC will start the review process.

The NZGBC and the Modelling Assessor Panel will review the documentation submitted and determine whether or not the applicant demonstrates the qualities required to be an AEM.

If it is agreed by NZGBC and the Modelling Assessor Panel that the applicant is eligible to become an AEM, then the NZGBC will advise the applicant of the success of their application (via email) and issue their biennial certification fee invoice ($750 excl. GST) minus the application fee of $350 excl.gst.

To ensure the integrity of the Green Star system is maintained the NZGBC requires Accredited Energy Modellers (AEM) to undergo biennial re-certification and credential maintenance.
Each AEM is required to apply every two years for their practising certificate. The fee is $750 excl. GST 
Eligibility requirements to retain their accreditation will be reviewed every four years. It is expected that they should have completed at least two Green Star models within this period.

In order to be eligible, applicants must have;

  • At least 2 years of energy modelling experience, in the modelling programs accepted by Green Star(Only modelling programs that have been independently tested by BESTEST and/or ANSI/ASHRASE standard 140-2004 will be accepted by Green Star)
