  Indicators

International building sustainability standards set out environmental and other indicators for calculation when undertaking building LCA . These are based on environmental impacts using Life Cycle Impact Assessment. 

Indicators.pngLCAQuick calulates the following environmental indicators:

  • Climate change (100 years)
  • Stratospheric ozone depletion
  • Acidification (land and water)
  • Tropospheric ozone formation
  • Eutrophication
  • Abiotic resource depletion - elements
  • Abiotic resource depletion - fossil fuels

In addition, LCAQuick calculates:

  • Primary energy (total)
  • Primary energy (non-renewable)
  • Primary energy (renewable)

The BRANZ SR293 study report sets out how these and future potential indicators for inclusion in the framework were derived.  It also provides information on the preferred method for their calculation and characterisation factors to use.
