Changes to Green Star – D&AB v1.2, Interiors v1.2 and Communities v1.1

The use of Life Cycle Assessment (LCA) is gaining greater recognition in sustainability assessment.  An LCA credit is embedded as a core credit in the Green Star rating tools Design and As Built v1.2, Interiors v1.2 and Communities v1.1.

eTool have completed and peer reviewed over 50 LCAs for Green Star projects and we have a great group of eToolLCD users that are constantly providing feedback to improve the way we quantify and improve project performance using Life Cycle Design.

In early July 2017, Green Star released the 1.2 version for Design and As Built and Interiors rating tools and the Materials Life Cycle Impacts credit was further improved, as follows:

  • Points may now be easier to achieve for some projects provided there’s early engagement of LCA consultants
  • Projects registered with Green Star after September 2017 will need to engage early. Projects that wait until very late in the design process to begin the LCA may be limited to 4 points of the available 7.
  • Points allocation have been adjusted with operational energy reductions capped.
  • Further Additional Reporting initiatives were added with extra points available.
  • Additional guidance throughout to improve clarity and other updates.

Design and As Built v1.2 points breakdown – Up to 7 points in total:

  • Up to 6 points for performance (limited to 3 points for operational energy improvement)
  • Up to 1 point for LCA Design Review (early stage)
  • Up to 1 point for material changes informed by the LCA
  • Up to 1 point for construction process change informed by the LCA
  • Up to 1 point for reporting additional indicators
  • Innovation: 1 additional point where the cumulative impact reduction as defined within the credit is increased by 20% to a total of 150%.

Interiors v1.2 points breakdown – Up to 19 points in total:

  • Up to 18 points for performance (limited to 12 points for operational energy improvement)
  • Up to 1 point for reporting additional indicators
  • Up to 2 points for material changes informed by the LCA
  • Up to 2 points for construction process change informed by the LCA
  • Up to 2 points for LCA Design Review (early stage)
  • Innovation: 1 additional point where the cumulative impact reduction as defined within the credit is increased by 20% to a total of 150%.

Communities v1.1 points breakdown – Up to 5 points in total:

  • Up to 4 points for performance (whole of site impact reduction)
  • Up to 1 point for reporting additional indicators

The Life Cycle Design process using eTool services will now be:

  • Target Setting Study conducted at Concept Design Stage
  • Life Cycle Design Services conducted later in the design project when energy modelling has been undertaken

Note to eToolLCD users: The Indicator verse Life Cycle Phase Summary report can be used for LCA Design Review. The Target Setting report will be updated soon to include multiple indicators.

eTool hosted a webinar to present the recent changes in Materials Life Cycle credit and how to maximise design value using LCA methodology.

Stay tuned for other updates and get in touch if you need further details.
