CREATING SUSTAINABLE HOMES

Getting a rating – the process

Step 1: Registration

Registering your project with NZGBC is the first step towards getting a Homestar rating. This ensures the technical team is aware of the project, and can provide support and guidance. It’s a good idea to register your project as early as possible. To register a Homestar project, complete the Homestar Registration Form and email it to us.

Step 2: Pay auditing and admin fee

When a project is registered, we will send an invoice to cover audit and admin fees. You can see how Homestar Certification Fees are calculated and download the Homestar Price Calculator for your own project.

  • Within two weeks of NZGBC receiving your payment, we will send a Homestar Registration Letter that specifies the registration codes for your project. This letter can be used to support resource consent applications if needed.

Step 3: Assessment

Projects can achieve two levels of Homestar assessment: Design and Built. Of these, only the Built rating is compulsory. However, most projects choose to be assessed at an earlier stage to provide assurance and enable the Homestar rating to be used before the build is complete. All assessments must be carried out by qualified Homestar Assessors.

For new build projects, the fee you pay at the beginning of the Homestar process covers both levels of assessment.

Design rating

To carry out a Design rating, the Assessor reviews the building consent (or later) design drawings and specifications against Homestar criteria. The Assessor must personally sight each piece of documentation before awarding points.

  • The NZGBC will audit Design ratings within two weeks of receiving the submission.
Built rating

All projects must undertake a Built rating. This is carried out once the project obtains practical completion, and confirms the finished house has been constructed in line with the Homestar rating. Homestar Built ratings may be carried out for existing homes and new builds.

To undertake a Homestar Built rating, the Assessor reviews the complete property and personally sights each piece of documentation.

  • The NZGBC will audit Built ratings within two weeks of receiving the submission.

Step 4: Auditing

Whatever level of assessment your project is undergoing, it will be audited by an independent third party.

Step 5: Certification

Once the final Homestar rating is confirmed, NZGBC notifies the project team and the appropriate logos are sent out to be used in marketing and communications.
