Aquatic Plant and Control Upgrades – Saving Money, Lowering Emissions for Council

The City of Maroondah (Council) is a local government area situated in the Eastern suburbs of Melbourne, Victoria. The Council – a member of the Eastern Alliance for Greenhouse Action – is proactively seeking ways to mitigate climate change risks through energy conservation and sustainability projects in line with its Carbon Neutral Strategy & Action Plan adopted in 2015, Climate Change Risk and Adaptation Strategy (2018 – 2022) and 2040 vision for a clean, green and sustainable community. The Council identified Aquanation among other facilities to be assessed and upgraded for operational improvements, emission reduction and energy savings. Ecosave was chosen as the preferred tenderer to partner with the Council to provide services for its operation and energy optimisation plant and control upgrades at Aquanation.

 

THE SOLUTIONS THAT ECOSAVE HAVE BEEN IMPLEMENTED INCLUDE:

•Upgrade of Tridium Niagara site AX to cloud-hosted Tiridum Niagara N4 system with Ecosave Watch Data Analytics

•Chilled Water System optimisation including buffer tank installation, primary & secondary variable flow control, CHW and CDW reset

•Heating Hot Water System optimisation, new condensing boiler staging control, primary & secondary variable flow control, HHW reset (ensuring condensing mode)•Pool Heating control installation, removed from pool PLC control, replaced OPEN/CLOSE valve actuators with modulating type

•Pool Hall AHU and heat wheel optimisation, improved fan speed control for improved humidity and static pressure conditions, reduce evaporation

•Gym and Program Room, 12 x FCU Economy Damper retrofit and control As a result of these solutions, the City of Maroondah have reduced their annual electricity usage by more than 157 MWh and greenhouse gas emissions by 255 tonnes (CO2-e p.a.) – equivalent to C02 emissions from more than 55,000 kg of coal being burned – every year
