Green Star FAQs

In Regards to 19A - Life Cycle Assessment in Green Star - Design & As Built v1.2 the GBCA clarifies the following:

19A.1 – Comparative Life Cycle Assessment - Are exceeding benchmark points available for operational energy improvements beyond the three (3) capped points

The GBCA clarifies that exceeding benchmark points can only be achieved if the cumulative reduction from modules other than B6 exceeds 3 points. Please note that under this version of the rating tool no more than 2 points can be achieved for an 'Exceeding Green Star Benchmarks' claim. 

19A.2 – Material Selection Improvement -  Should Module B6 be included in the reference case (initial scenario from which reduction % is calculated) when calculating “total cumulative impact reduction (excluding B6)”. 

The GBCA clarifies module B6 is excluded from the reference case. 

19A.2 – Construction Process Improvement - Does the “percentage cumulative impact reduction” refer only to a relative reduction for modules A4 and A5

i.e. the reference case (initial scenario from which reduction % is calculated) excludes all other modules.

It is confirmed that reference case excludes all other modules, and therefore the cumulative impact reduction is relative to the sum of impacts from module A4 and A5.
