Major Adelaide office tower undergoes digital optimisation to cut energy use and improve operational performance

Schneider Electric

• A digital services program leveraging predictive analytics and remote monitoring has reduced overall annual energy demand by almost 50 per cent, while gas consumption is down 5 per cent year‑on‑year.

• Targeted Energy Conservation Measures, have improved HVAC responsiveness, strengthened system visibility and enhanced overall building efficiency.

• By shifting from reactive maintenance to proactive optimisation, the program has extended HVAC asset life by at least 20 per cent while improving thermal comfort across all 30 floors.

Adelaide, Australia, 23 April 2026 – A major digital performance upgrade at 91 King William Street is delivering significant sustainability gains, cutting almost half of the HVAC electricity use and 5 per-cent of gas consumption annually, extending HVAC asset life by at least 20 per cent and improving thermal comfort across all 30 levels of the building.

The A-Grade office tower, widely regarded as one of Adelaide’s premier CBD addresses, has undergone a structured optimisation program to enhance digital performance, efficiency and long-term resilience. Delivered by Abacus Group, a real estate investment and asset manager, with support from Schneider Electric, a global energy technology leader, the upgrade modernises building systems and strengthens data visibility, addressing the challenges associated with ageing mechanical and electrical infrastructure.

The program was delivered through Schneider Electric’s EcoCare Advanced service model, combining predictive analytics, remote monitoring and condition‑based maintenance with on‑site engineering support, with Knight Frank supporting implementation by coordinating stakeholders and integration across the delivery teams. Continuous data analysis enabled the team to shift from reactive maintenance to proactive performance optimisation.

 

Letitia Woodforde, Capital Works and Operations Manager at Abacus Group, said the results reflect the value of a data-led and collaborative approach.

 

“It shows great results so far. The downward consumption trend and improved thermal comfort are very positive outcomes. The achievements are great!”

Leveraging Schneider Electric’s Digital Services platform, the initiative began with a comprehensive Building Management System energy audit, which identified targeted opportunities to reduce energy demand, improve HVAC responsiveness and enhance monitoring of critical systems. Stage 1 of the Energy Conservation Measures delivered immediate efficiency improvements. Following its success, Stage 2 was commissioned and is now in the final system tuning and Measurement and Verification phase to confirm and lock in performance gains.

For Abacus Group, improving the performance of major assets such as 91 King William Street is central to its portfolio-wide sustainability objectives. Strong energy performance supports the group’s net-zero ambitions while enhancing tenant comfort and long-term asset value. 

 

Louise Monger, Vice President Digital Energy at Schneider Electric, said the project reflects the growing role of intelligent, sustainable buildings in the future of commercial property.

 

“Smart, sustainable buildings are no longer a future ambition, they are a business priority. The real opportunity lies in unlocking more performance from the buildings we already have.

 

At 91 King William Street, digital services and continuous optimisation have delivered measurable energy savings, improved tenant comfort and extended the life of critical infrastructure. That’s the power of combining data, expertise and long-term thinking to create buildings that are not only more efficient, but more resilient and future-ready.”

 

With further Energy Conservation Measures planned, 91 King William Street is positioning itself as a benchmark for smart, sustainable performance in Adelaide’s commercial property sector.
