Cutting edge technology and smart features elevate the building’s sustainability to a whole new level.

Advancing environmental efficiency

From its design to its delivery, EY Centre has had sustainability at its heart – setting new benchmarks for sustainability and heritage interpretation.

EY Centre is one of Australia’s most environmentally advanced and sustainable buildings, representing World Leadership in environmental sustainability practices. From its world-first automated Closed Cavity facade to its exclusively LED lighting, the building optimises energy efficiency on all fronts. Air quality is improved via minimisation of VOCs and formaldehyde, and sophisticated building analytics enable constant monitoring of energy and water use. Sustainable commuting is made easy for tenants through the building's location close to public transport, and by the inclusion of 300 bicycle spaces and End of Trip facilities.

EY Centre's base building has achieved a 6 Star Green Star Office Design and 6 Star Green Star Office As-Built rating, a 5.5 Star NABERS Energy rating and a 3.5 Star NABERS Water rating.

Australian first GOLD WELL Certification

Mirvac’s tenancy at EY Centre is at the forefront of health and wellbeing, having achieved the first GOLD WELL Certification in Australia.

Mirvac secured this accolade by placing employees at the centre of its design decisions and actively promoting the health and wellbeing of its workforce. Partnering with the International WELL Building Institute, Mirvac achieved credits across seven categories including air, water, nourishment, light, fitness, comfort and mind.

Mirvac's headquarters has achieved a 6 Star Green Star Interior and a 6 Star Green Star As-Built rating, and is targeting a 5.5 Star NABERS Energy rating and 3.5 Star NABERS Water rating.

EY Centre also features a water recycling system to reduce potable water consumption and a comprehensive water metering system to monitor and manage potable water usage.

Water meters have been installed on high water usage equipment such as the building cooling towers to monitor and control consumption and added to areas such as the Fire Test System and the End of Trip facilities to research usage and feedback information into future developments.

    During construction of the building Mirvac used motion sensor lighting to save energy, and recycled approximately 90 per cent of construction materials to reduce landfill.

    The property achieved a recycling rate of over 80%, through detailed onsite segregation of waste streams, strong tenant and cleaner engagement and innovation.

    The EY Centre was one of 5 Mirvac properties to implement a separate recycling stream for coffee cups and bathroom paper towels, collected by the Mates on the Move social enterprise and converted into processed engineered fuel at the Suez waste treatment facility.


    At the project’s inception, Mirvac engaged specialist archaeology firm, GML Heritage, to enable archaeological investigations from the earliest stage, developing a process to manage ‘finds’ sensitively and recycle materials from the excavation.

    More than 23,700 artefacts from Sydney’s colonial history were recovered onsite.

    Indoor environmental quality

    Market leading ‘smart’ technology at EY Centre monitors air quality, sunlight, power and water usage and adjusts the internal environment according to the needs of the building and its occupants, allowing for amenity / efficiency improvements to be made in near real time.

    Mirvac’s tenancy within the EY Centre includes a Living Lab, heavily instrumented with indoor environment sensors to research the indoor environment and test technologies and approaches that improve sustainability .

    Mirvac’s headquarters at EY Centre is the first space in Australia to achieve a WELL certification from the International WELL Building Institute (IWBI) – the only standard to focus solely on the health and wellbeing of the buildings occupants. The headquarters secured a GOLD level of WELL Certification, one of only six others at the time to achieve this feat.

The Closed Cavity Façade

One feature that’s incredible both in appearance and functionality is the Closed Cavity Façade (CCF). This is a world-first, high-performance timber blind system that adjusts automatically in response to exterior conditions – effectively controlling heat and light, and reducing energy requirements and maintenance costs.
