Innovation 2 guidance and available credits - New Build
Technical Clarification Number

Guidance
2021-06-23
Where projects target New Build Innovation 2, the GBCSA would expect to see a viable justification for the degree to which the benchmark is exceeded (i.e. the threshold) and how this translates into an innovation and significant environmental impact. Projects are therefore required to either make use of the existing credit thresholds/benchmarks as per the Inn-2 table below, or motivate for new credit thresholds/benchmarks.
The process for assessing Inn-2 credits is as follows:
As a general rule, where quantitative thresholds required to eliminate environmental impact, or to have a restorative environmental impact of at least 5%, are nominated in the Inn-2 table below, these will be accepted. This assumes that all documentation and Technical Manual requirements are met.
Innovation 2 credits, however, may also be submitted for assessment where quantitative thresholds required to eliminate/restore environmental impact are not nominated by the Inn-2 table below or are new credit nominations by the project. In such instances, the GBCSA will assess the credit during Round 1. If the proposed quantitative thresholds required to eliminate environmental impact is queried, the GBCSA will request a CIR or TC to be submitted prior to Round 2 to confirm if it is available to be targeted. Projects must ensure that an approved motivation/request is provided where a credit is not included within the scope of Inn-2 as defined by the Inn-2 table below, clearly indicating why exceeding the current Green Star benchmark would have an environmental benefit. If approved, this will be considered for inclusion in the Inn-2 table below.
The available Green Star New Build (Office, PEB, Retail, MUR) credits are shown in the table below (with their corresponding thresholds to achieve points under this innovation credit:
|
