NABERS Recognises 3E Group for 99 St Georges Terrace in Perth elevate its energy efficiency and create a comfortable, modern workplace

Ecosave services agreement

29 November 2022

NABERS have recently published a case study on 99 St Georges Terrace, Perth outlining the impact of the energy efficiency solutions implemented as part of a 10-year Services Agreement funded and delivered by 3E Group (formerly Ecosave Australia & NZ). The energy efficiency solutions implemented by the 3E Group via the agreement helped 99 St Georges Tce go from 0 Star to 4 Star NABERS Energy Rating and save $100,000 in annual energy costs – within three years.

Project Highlights

  • 99 St Georges Terrace in Perth’s CBD offers 6,123 square metres of net lettable area across 13 floors and 18 tenancies. 
  • In 2018, the building had an ageing central plant, a zero NABERS Energy rating and a 75% vacancy rate.  Mesatech (owner) and Cygnet West (property manager) understood the importance of obtaining a high NABERS rating as most businesses are looking for a 3 star NABERS energy rating as a minimum.
  • They engaged 3E Group (formerly Ecosave Australia & NZ) – a leading performance-based ESCO – who were able to provide a guarantee of 4 Star NABERS Energy Rating.
  • 3E Group designed, funded and implemented more than $750,000 worth of  energy efficiency upgrades and energy management solutions that would elevate the NABERS rating from 0 to 4 Star NABERS Energy Rating.
  • For a zero-dollar upfront cost, 99 St Georges Terrace received a full upgrade to its HVAC plant and metering, to the tune of $751,350. The owner is expected to save $140,000 in annual cost savings (energy and maintenance) when the building is fully leased.
