580 George Street was in need of an energy efficiency improvement upgrade to help meet its target NABERS Energy rating of 4+ Stars.
Having been designed in the 80s and completed in 1988, common plant served both the office tower and retail area, inhibiting the building’s overall energy performance.
As part of a collaboration with major tenant HSBC, and as part of an Energy Performance Contract (EPC), GPT Group undertook a building plant upgrade to improve energy efficiency and achieve a minimum 4.5 Star NABERS Base Building Energy rating.
A.G. Coombs Advisory assisted A.G. Coombs Projects in delivering the EPC. The EPC involved a number of Energy Conservation Measures (ECMs) specifically designed to improve the building’s NABERS Base Building Energy rating to 4+ Stars.
Several energy improvement initiatives were identified, designed and implemented, including:
- A chilled water plant upgrade.
- A Building Management and Control System (BMS) upgrade.
- Condenser water system engineering.
- Lighting upgrade works.
- Extensive building tuning.
- Additional energy metering.
The initiatives drove immediate improvements to energy performance, with the building soon operating above the target 4+ Star NABERS Base Building Energy rating. The findings also helped to future-proof the facility for further improvements across the building’s lifecycle.
