Mirvac has completed the electrification of EY Centre at 200 George Street in Sydney, bringing the number of fully electrified office buildings in its portfolio to five.

Co-owned by Mirvac and M&G Real Estate, the office tower holds a 6 Star Green Star rating and a 5.5-star NABERS Energy rating. The upgrade involved replacing gas-based systems with high-efficiency electric heating and hot-water systems that use natural refrigerants.

The upgrade replaced gas-based systems with high-efficiency electric heating and hot-water systems.

Mirvac chief asset management officer Victoria Tavendale said the project supports the company’s target to decarbonise its portfolio by 2030.

“Projects like this are critical to how we decarbonise our portfolio over time. They allow us to reduce our reliance on offsets, respond to tenant demand and position our assets for the future,” said Tavendale.

“By removing gas from core building systems, we’re reducing emissions and ensuring the asset remains competitive for tenants with net‑zero commitments.”

Electrification is being driven by growing demand from corporate occupiers. JLL’s 2025 report, The race to decarbonise Australian office markets, found about 85 per cent of large Sydney CBD tenants have net-zero targets, many with deadlines by 2030. It also found the supply of all‑electric office space remains limited, creating an opportunity for commercial property owners who act early.

“We’re seeing sustainability move from a differentiator to a core requirement in leasing decisions,” said Tavendale.

M&G Real Estate head of Australia Alex Banzic said the upgrade will help meet occupier expectations while improving the building’s environmental performance.

“The electrification of EY Centre builds on the asset’s strong track record in innovation and sustainability, helping ensure it remains relevant, resilient and attractive to occupiers over the long term,” said Banzic.

Mirvac CEO, Investment Richard Seddon said electrification supports the company’s net positive carbon target and helps meet demand for lower-carbon office buildings.

“EY Centre forms part of Mirvac’s wider program to electrify its office portfolio, which is now embedded into Mirvac’s portfolio-wide strategy and strategic asset planning processes,” said Seddon.
