Mirvac’s EY Centre in Sydney has taken out the top award at the CIBSE Building Performance Awards this year.

For demonstrating excellence in functionality and sustainability, the Chartered Institution of Building Services Engineers awards named Mirvac’s EY Centre Project of the Year – International. The 33 storey Sydney development was recognised by CIBSE judges for its delivery of “premium-grade office space whilst achieving demanding sustainability targets”. 

The use of a world-first timber-and-glass closed-cavity façade (CCF) system was key to this sustainability performance. 

“The facade is characterised by the revolutionary use of timber,” Mirvac Construction general manager, design management & construction Jason Vieusseux said.

Prior to the EY Centre, a closed-cavity façade had never been used on a high-rise before. We wanted to reimagine the commercial high-rise as an art form.

“The best thing about the project is its sense of place; the vision was to use natural materials, in this case timber and stone, to make it more inviting.”

This is not the first award the EY Centre has received. It also took out the Construction Award at the 2018 Council on Tall Buildings and Urban Habitat (CTBUH) awards.

Lark Rise, London

CIBSI’s Project of the Year – Residential was awarded to bere:architects’s  Lark Rise for its outstanding in-use performance, energy efficiency and reduced carbon emissions.

The London home is as energy efficient as it is visually attractive – generating twice as much energy as it uses. A certified passive house, Lark Rise has a 12kW rooftop solar array that – after two years of monitoring – has been found capable of exporting ten times as much energy as it imports from the grid. 

In 2018 a 13kWh battery was installed in the home with the intention of taking the 65 per cent self-consumption statistic to 85 per cent, further reducing the building’s reliance on the grid.

CIBSE’s Building Performance Awards recognise completed projects which demonstrate outstanding in-use performance, architectural design and facilities management, as well as products for their contribution to delivering outstanding building performance.
