The National Energy Efficiency Awards recognise and celebrate excellence in energy management, energy efficiency and demand response across Australia.
This year A.G. Coombs with Thermal Energy Solutions have been recognised with the Integrated Clean Energy Award 2022 for the gas hot water plant conversion at 101 Collins Street.
The award recognises projects that have demonstrated excellence in integrating high levels of energy productivity and renewable energy considering aspects of performance, leadership and innovation.
This project in a high-profile existing building showcases a practical and achievable technology solution to improve energy efficiency and degasify and electrify to remove Scope 1 emissions.
The project converted domestic hot water generation from the original building calorifiers, connected to the buildings natural gas-fired heating hot water plant, to a system featuring highly efficient commercial heat pumps, smart thermal storage calorifier tanks and solar PV collectors to provide off grid DC electrical energy production.
During the initial period post final commissioning the new plant reduced energy consumption by 81% compared to the previous plant and reduced associated greenhouse gas emissions.
