The Liberty Place building in Sydney is one step closer to its zero carbon emissions goal with the introduction of a fully automated tri-generation system.
Johnson Controls has been busy at Liberty Place installing a fully integrated building solution which has enabled the building to achieve energy savings of 20 per cent.
Liberty Place is a new premium grade office complex in the heart of Sydney’s central business district by leading developer Grocon.
Spanning five separate sites, including Legion House, a heritage building dating back to 1902, Liberty Place has a total of 58,316 square meters of office space and 2,800 square meters of retail space.
In recognition of the complex’s sustainable design and enhanced operational efficiency, it was conferred the 6-Star Green Star Rating by the Green Building Council of Australia and 5.0 Star NABERS (National Australian Built Environment Rating System) by the Office of Environment and Heritage.
At the heart of the solution by Johnson Controls lies a fully automated tri-generation plant that is integrated into the daily operations of the building.
The system allows for the simultaneous generation of electricity and useful heat and cooling in a single process.
The comprehensive solution from Johnson Controls includes:
Energy-efficient YORK YK centrifugal chillers and YORK YIA absorption chillers optimally configured in the chilled water system
Re-engineering of existing plant room to reduce footprint by a third
Re-engineering of pumping systems to reduce chiller pump power
Sabroe SABlight air-cooled chiller to provide option of generating power via synthetic gas produced by gasifier or natural gas
Central Plant Optimization 10 (CPO10) software powered by Metasys to optimize the performance of the chiller plant
Metasys Energy Dashboard software to track savings from each perimeter and provide a holistic analysis of the building’s energy efficiency
