Homestar Governance

As part of our commitment to improving the health, efficiency and sustainability of homes across Aotearoa, we work with experts across industry and government to regularly review Homestar while maintaining its reputation as one of the leading independent certification tools for new homes.

Central to our work is a focus on home health, carbon and decarbonising the built environment. Our advisors consider the impact of carbon at each stage of the building lifecycle including operational carbon, embodied carbon, energy reduction, water efficiency, surface water run-off, waste to landfill, waste reduction, and the circular economy in supporting resilient communities.

The Advisory Committee and Expert Reference Panel have been established to:

  • Provide specialist technical advice related to Homestar as a holistic certification tool
  • Bring independent thinking and drive continuous improvement to adapt to change in the regulatory, environmental and social conditions across Aotearoa New Zealand
  • Evaluate the views of stakeholders as submitted through the stakeholder consultation process

Homestar Advisory Committee

The Homestar Advisory Committee works across the Expert Reference Panel (ERP) to consolidate recommendations for the NZGBC Leadership Team and Board on all matters relating to the development of Homestar. In doing so, they are committed to ensuring that the Homestar certification system remains rigorous, market relevant, and valued by industry.

Members of the Homestar Advisory Committee are sustainability leaders with experience in rating systems and the role of independent certification in driving change. They hold senior positions in their organisations and understand the economic, social and environmental drivers that affect the adoption of sustainable building practices.
