Homestar accreditations

Get qualified to deliver Homestar projects and support the industry to deliver better, more sustainable homes

Upcoming courses
Every year thousands of professionals help design and build homes with a focus on better performance and environmental outcomes. We offer several options for those seeking to learn more and get accredited to deliver Homestar certification. 

Whether you're interested in learning about sustainable home design and construction, or want to actively participate in submitting a Homestar project for assessment, we offer a range of accreditations to build your knowledge.

Our courses cover the latest Homestar requirements and sustainable home practices, providing formal accreditations to help you deliver New Zealand's leading sustainable home certification.

Homestar offers three courses: Fundamentals, Designer, and Assessor. As a certified Homestar Professional (Designer or Assessor), you’ll receive a digital certificate and permission to use the Homestar Professional logo in your promotional material.

Homestar Fundamentals

This is a self-paced, online course.

The Homestar Fundamentals course is for people with an interest in healthy, warm homes, and their sustainability. This course is for those who want to play a key role in the sustainability of the built environment and are keen to communicate the benefits of Homestar.

Those who have done the course will have good knowledge of the fundamentals of Homestar and can communicate its benefits to the market, understand how their products or services will help achieve Homestar ratings, and assist in the design and construction of Homestar projects. 

The fundamentals course takes approximately 6 hours to complete. 

There are no formal pre-requisites for this course. However, it is recommended that participants have experience in home design and construction, the Healthy Home Standards, and the New Zealand Building Code.

There is no exam element to the Homestar Fundamentals course.

Homestar Designer: Residential Energy Modelling 

This course is delivered either live via Zoom over 7 weekly sessions, or in person as two consecutive full-day sessions.

The Homestar Designer: Residential Energy Modelling course focuses on building an in-depth understanding of the theory and application of the Homestar rating tool and principles of sustainable design. Designers are trained to design and advise on the technical aspects of Homestar and the principles of sustainable design, so they can apply this knowledge when working on a Homestar project.

Attendees of the Homestar Designer training course must have passed the Homestar Fundamentals course (previously called Homestar Practitioner) and meet one of the pre-requisites listed below.

This is a technical accreditation that requires an understanding of how homes are designed and built in Aotearoa. Attendees must be able to read and interpret house plans and have a basic understanding of building science. Therefore, one of the following qualifications and/or experience is required to attend

  • Architectural designer, architect
  • Engineer 
  • Building scientist/technologist 
  • Quantity surveyor 
  • Licensed Building Practitioner Level 2 and 3 

If you feel you have equivalent experience, please contact us.

Yes. After the course participants need to pass the online examination within 4 weeks of attending the course to receive their accreditation.

  • Architectural designer or architect

Frequently asked questions

We encourage people to attend this course as an introduction to Homestar. It is particularly useful for those working for a product supplier, a local or national regulatory body, or any other organisation that needs to familiarise themselves with the requirements of Homestar and how they can be met, but who won’t be directly involved in designing, building, or assessing homes. This course is also a prerequisite for both the Designer and Assessor courses.

A Homestar Designer is trained to advise on and design homes that meet the requirements for Homestar certification. A Homestar Assessor, on the other hand, is qualified to submit a Homestar project for official certification.

This depends on your situation. To submit a Homestar v5 project, you’ll need both a Homestar Designer and a Homestar Assessor on your team. For small practices or sole contractors, this means you must have both the Homestar Designer accreditation, which allows you to do the energy modelling of the built home, and the Homestar Assessor accreditation, which enables you to perform additional calculations and submit the assessment.

In larger teams, you have the option to have both an in-house Homestar Designer and an in-house Homestar Assessor working on the same project.

There are no prerequisites for the Homestar Fundamentals course. However, you must complete this course and exam before attending the Homestar Designer or Assessor courses.

While the listed qualifications are recommended, if you have relevant experience not listed, please contact education@nzgbc.org.nz
