What you need to know

Gas replacement is rarely a standalone task - it’s part of a broader challenge facing ageing buildings and the people responsible for them. Whether triggered by regulation, risk, or retrofit opportunity, moving off fossil fuels can feel complex and overwhelming.

This hands-on masterclass helps cut through the paralysis. Through real-world insights, cross-disciplinary thinking, and practical steps, participants will gain clarity on how to decarbonise existing buildings.

Delivered by experts from NZGBC, Apricus Eco, and Mott MacDonald, and generously hosted by BNZ with heavy subsidy from EECA, this masterclass equips you with the knowledge and tools to confidently lead fossil fuel phase-out in existing buildings.

Learning outcomes:
  • Identify the key questions to ask - and who to involve - to kickstart a decarbonisation journey

  • Build or assess a business case for removing gas and diesel from existing buildings

  • Evaluate technical options and navigate real-world constraints in live projects

  • Understand the support mechanisms available and learn from real case studies

  • Take informed, practical action based on your role and organisational context
