Method: 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.
Results: 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. As well as the results below, the annual water savings identified was 47 Million Gallons, which is a 22% reduction! Projects have an average simple payback period of 3 years.
