Green Star FAQs
Is 'Warm Charging' technology considered an energy-reducing process in steel reinforcement production?
Yes, 'Warm Charging' technology is considered an energy-reducing process in steel reinforcement production and project teams may demonstrate compliance with credit 20.1B Energy-Reducing Processes in Steel Reinforcement in the Green Star - Design & As Built rating tool provided that the following is also met:
- The steel manufacturer has had their 'warm charging' process peer reviewed by an independent third party LCA practitioner and agrees to comply with any recommendation made by the peer reviewer; and
- The steel manufacturer provides annual updates on the process that are publicly available, to help educate the wider industry on the benefits of warm technology process.
The benchmarks for steel reinforcement quantities remain as per the Submission Guideline whereby at least 60% (by mass) of all reinforcing bar and mesh is produced using energy-reducing processes in its manufacture.
