  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, and values for flows in the Life Cycle Inventory. Indicators.png

LCAQuick - Office presents a subset of these indicators due to data limitations.

NZGBC requires a further subset of indicators for the purposes of calculating the Innovation Challenge Material Life Cycle Impacts.

The table below provides a summary.

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.
