Thermosash Auckland's Henderson headquarters is an awesome adaptive reuse success story:

Certifications

  • 6 Star Green Star Design and As-Built NZ V1.0 Certification by the New Zealand Green Building Council (NZGBC) - awarded in May 2025.
  • Certified Gold Airscore AirRating for the internal environment measuring occupational CO2, PM2.5, TVOCs, relative humidity and temperature. Only the second building in New Zealand to receive this rating.

This makes the Henderson building a world-leader in sustainability - showcasing that Thermosash is committed to creating environmentally responsible building solutions whilst enhancing operational quality and efficiency.

Awards

'Excellence and Best in Category - Industrial Property Award' at the Property Council New Zealand Rider Levett Bucknall Property Industry Awards 2025 evening held on Friday 13 June.

Carbon Savings

  • 95% of the building façade and 95% of the existing structure was reused along with a proportion of the building's services. Adaptive reuse of the building has saved approximately 7000 tonnes of CO2 equivalent of upfront embodied carbon compared to a new reference industrial building.
  • Greenhouse gas emissions from the base building are predicted to be reduced by 70% compared to a reference industrial building using a combination of energy efficiency measures and renewable energy generation - usage excludes factory and office equipment loads.
  • The building is predicted to save 15,000 tonnes of operational carbon emissions over its typical 50-year
    building life cycle compared to a reference industrial building.
  • Including upfront and operational carbon emission savings the total savings over the 50-year building life compared to a new reference industrial building are predicted to be
    22,000 tonnes of CO2 equivalent.

Project Completion

The project was completed in 2023, 50 years after Thermosash was founded in 1973.  

Grateful Thanks

It takes teams of people working collaboratively to achieve these successes, and we congratulate and thank all involved.
