What you need to know
Despite recent shifts in priorities, Homestar remains one of the most cost-effective ways to ensure homes meet appropriate standards of comfort, health, and durability—without adding unnecessary luxury or cost. We’ll unpack how Homestar:
• Supports taxpayer and ratepayer value through long-term durability and reduced operational costs
• Offers scalable, low-cost certification through the Homestar Ready pathway, (originally developed in conjunction with Kāinga Ora’s Housing Delivery System)
• Provides a verified compliance pathway for H1/VM1 via ECCHO modelling
• Addresses emerging challenges like overheating and internal moisture—issues not adequately covered by current Building Code standards
• Enables councils to lead on resilience and performance, even within existing legal constraints
This session will also clarify the misconception that performance equals luxury, and show how Homestar can be a practical, accessible solution for large-scale housing delivery.
Whether you're involved in planning, policy, development, or sustainability, this webinar will equip you with actionable knowledge to advocate for and implement better housing outcomes across your organisation.
