The EECO2 team conducted the on-site energy and water reduction assessment workshop events, working together with the site engineering teams and other stakeholders. The scope included a review of opportunities in HVAC systems serving all areas, utility generation & distribution (steam, chilled water, cooling water, compressed air systems) and water systems.
EECO2 recommended that the client’s focus should be on rapidly implementing HVAC & BMS optimisation opportunities as these have high cost reduction, short paybacks and excellent emissions reductions. As an example, since the event took place, one site implemented optimisation of controls on several HVAC systems, which delivered $190k annual savings with a simple payback of 6 months. As well as the larger energy projects, the events identified 143 ‘Just Do Its’, which are low or no cost actions that site teams can action immediately.
The identified savings based on 273 developed projects.
The average simple payback period for all projects in this case study is 3 years.
The final report to the client showed a total avoided cost of $50 Million per year is achievable by 2025.
The projects identified in this programme represent extremely good value investment opportunities to realise significant sustainability improvements, which will aid the client in meeting corporate targets.
