tbl-edmondsonTransport for NSW’s newly proposed Sustainable Design Guidelines (SDG) v4 were critically assessed for financial, environmental and social performance over a 50-year lifetime, using the Edmondson Park Interchange as a case study.

The performance of each compulsory requirement of the new SDG v4 was confirmed and used to help inform further development of the SDG v4.

Life cycle costing, life cycle assessment and social value analysis was completed for all variants of all SDG v4 compulsory requirements. Three scenarios (Pass, Silver and Platinum) were then compared to a benchmark scenario (minimum compliance) to ascertain the environmental, financial and social comparative performance.
