LCAQuick live webinar


Life cycle assessment calculates the potential environmental impacts and carbon footprint of a building design across the life cycle. 

This webinar provides a basic introduction to using the BRANZ building life cycle assessment tool, LCAQuick. It builds on the life cycle assessment webinar by providing a practical demonstration of LCAQuick, going over the basic inputs and outputs of the tool.

The latest version of the tool includes:

  • evaluation of different building typologies
  • a reference building library for:
    • 10 commercial office buildings in three climate zones
    • 10 stand-alone houses, one medium-density housing and one apartment building in three climate zones
  • environmental impact of materials used in commercial office building and residential housing construction in Aotearoa New Zealand
  • operational energy use from grid electricity
  • comparison of alternative constructions based on embodied carbon
  • a tool to calculate material quantities of windows and doors based on window/door type and frame material
  • a Green Star outputs worksheet that puts LCA results into a format that can be pasted directly into the New Zealand Green Building Council's LCA calculator tool [XLSX, 383 KB]
  • a separate editable PDF template report to support a Green Star submission for obtaining the LCA points under credit 19A.
