Homestar is a separate standard from the Passive House certification.

It is a comprehensive, independent national rating tool, run by the not-for-profit Green Building Council (New Zealand), that measures energy, health and comfort, water, waste, materials, site, home management, and an optional innovation category.

It’s a start into the right direction supporting people who want to build genuine long-lasting healthy homes. More should be done, though.

Tip: In addition, there is one major bank in New Zealand that provides a special home-loan rate when you build a healthy home with a Homestar rating 6+ which is easily achieved with a Passive House.
