A Melbourne commercial structure has been named the premiere “triple-crowned” building in Australia, attaining at once 6-Star NABERS ratings for Energy, Indoor Environment and Waste.

The 171 Collins Street building, co-owned by Charter Hall Group and Cbus Property, had been acknowledged previously for its milestones in sustainability and waste management.

While the seven-year-old structure was previously 6-Star certified by NABERS for Waste and Indoor Environment, its Energy rating only this year increased from a 5.5 to 6-Star, completing the Australian-first milestone.

In 2019, it was named the premiere office tower in Australia to attain a 6-Star NABERS Waste rating, and it has since kept a 75 per cent recycling rate.

The building maintains a 5-Star NABERS Water rating and a 5-Star Green Star performance rating.

Says Cbus Property’s chief executive officer, Adrian Pozzo, the structure–the global headquarters of mining giant, BHP Billiton–was designed to attain a 5-Star Energy rating, yet developments had proven that performance could be progressively enhanced through time.

Charter Hall’s regional portfolio manager, Nicole Ward said that 171 Collins Street attained a higher NABERS rating by:

  • Improving the operations of the building’s cogeneration plant
  • Reviewing and rendering optimum programming of the structural automation systems
  • Proactively cooperating with tenants concerning any mechanical leakage in the UFAD (Under Floor Air Distribution) that may be happening because of fitouts – an energy waster, as the plant was not operating in an effective manner.
  • Completing a deep clean of the building’s cooling towers, which has supplied an approximate 12-15 per cent increase in efficiency and bore a knock-on effect upon energy consumption.

The whole 33,000 square metre building is empowered by renewable energy by way of the City of Melbourne’s second Melbourne Renewable Energy Project (MREP2).

The power purchase agreement united seven large energy users, including Cbus, to which Tango Energy promised to supply 110 GWh of renewable energy annually from wind farms in Victoria.

NABERS director, Carlos Flores stated that 171 Collins Street was a leader for the commercial property business—in essence raising the bar regarding the performance of sustainable buildings.
