Life Cycle Analysis (LCA) in line with Green Star’s requirements
“Rewild’s life cycle assessment provided clear, evidence-based insights that directly informed material and procurement decisions for our fitout. Their practical approach enabled meaningful reductions in embodied carbon while remaining aligned with cost and program requirements, supporting the project’s achievement of a 6 Star Green Star outcome.”
— RLB Project Team
Project Overview
After nearly three decades on St Kilda Road, RLB were excited to move their Melbourne head office to Level 25, 55 Collins Street.
Rewild delivered a comprehensive Life Cycle Assessment (LCA) for the RLB fit out, supporting compliance with Green Star Interiors v1.3 Credit 19 – Life Cycle Assessment.
The assessment formed a critical component of RLB’s sustainability strategy, contributing to the achievement of 17 targeted credits under the Green Star Interiors v1.3 rating tool and significantly strengthening the project’s ambition to achieve a 6 Star certified fit-out.
Key Initiatives to Achieve Embodied Carbon Reduction
Interiors: FSC-certified timber, low-VOC finishes, and modular joinery.
Environmental Product Declarations (EPDs): Use of products with EPDs allowing modelling of product value chain improvements and reductions.
Recycled Products: Use of recycled timber in interior finishes.
Local Products: Procurement of Australian-made products over international alternatives.
Our Methodology
Collected material quantification data from cost plan and sub-contractor data.
Utilised online software e-tool (developed by Cerclos) to model the Reference Design upfront carbon, and the Proposed Design (including design and efficiency improvements) upfront carbon.
Conducted a cradle-to-practical completion LCA in accordance with ISO 14040/44 and Green Star Technical Guidance.
Modelled A1–A5 life-cycle stages, focusing on fit-out components.
Benchmarked results against the Green Star fit out reference model to identify reductions in embodied carbon intensity (kg CO₂-e/m² GFA).
Applied recognised Australian data sources (e.g., EPD Australasia, ISCA Materials Calculator, thinkstep GaBi) for product-level inputs – including both EN 15804+A2 and EN 15804+A1 indicators
Rewild Agency’s Impact
Achieved a 29.7% total LCA impact reduction relative to a ‘Reference Fit Out’.
Contributed to RLB’s 6 Star Green Star Interiors V1.3 assessment.
