From Design Intent to Operational Excellence: Mastering Building Performance in New Zealand

With building operations accounting for 28% of global carbon emissions, the challenge is one New Zealand is taking seriously. Backed by the Climate Change Response (Zero Carbon) Amendment Act, the drive to decarbonise existing buildings has never been more urgent.

From Wellington's heritage stock to Auckland's high-rise commercial assets, buildings are complex, dynamic assets whose requirements shift daily. Architects, engineers, owners and operators must balance energy, carbon, comfort and cost while meeting Green Star and NABERS NZ standards — all while bridging the gap between design intent and operational reality.

Join this session, hosted in partnership with NZGBC, to understand how to optimise your buildings, with a particular focus on data measurement and analysis, and how “performance digital twins” can be used as a route to cutting costs and carbon – helping you move closer to New Zealand’s goals of net-zero by 2050.

This session covers:

  • The problem with optimising existing buildings
  • The importance of whole-life building performance modelling across New Zealand’s diverse climate zones
  • An introduction to IES’ Performance Digital Twins
  • IES’s suite of Digital Twin tools for optimising building performance
    • IESVE for accurate whole building performance simulation
    • iSCAN for in-use building data analysis
    • IES Live for building decarbonisation and energy management
  • IES’s Digital Twins in Action
