The former site of Emu Brewery in Perth has been awarded a 6 Star Green Star rating for office design from the Green Building Council of Australia (GBCA).
The new home for Woodside Petroleum, Tower 1 Capital Square has achieved a 6 Star Green Star Office Design v3 rating - which represents world leadership in building design.
NDY associate and senior sustainability consultant Peta Earley said the 54,000 sq m tower on Mounts Bay Road will be the global headquarters for Woodside.
"Capital Square is one of the most significant commercial projects underway in Perth and to achieve a 6 Star rating is an outstanding result," he said.
“This is the only project in Perth to have achieved a 6 Star Green Star rating for Office v3 Design and demonstrates the commitment, drive and appetite from a client that understands the long term benefits of Green Star-rated projects."
GBCA CEO, Romilly Madew said the project was awarded 10 Innovation points for pioneering approaches to acoustics, lifecycle assessment and end-of-trip facilities, and has challenged the industry to meet higher benchmarks for sustainable design.
The sustainability team achieved a perfect 10 out of 10 score for ‘innovation’, and 12 out of a possible 12 for ‘management’.
“We managed to score a very highly regarded total of 77 points out of 100 for the overall 6 Star result with strong results across the ratings categories of transport, materials, energy and water,” Earley said.
The ‘unseen’ achievement of re-orientating from a focus on 5 Star to a 6 Star rating was a remarkable feat, according to NDY sustainability consultant Leigh Gibb.
“It was only late in the design phase – having been originally designed to achieve a 5 star Green Star rating – that we realised a 6 star rating was obtainable so NDY worked with the base building and tenant team to make this a reality," Gibb said.
Project leader and NDY senior associate Paul Bradbury, said collaboration has been integral to the project’s rating success.
“We have collaborated closely with the owners, architects and builders to create tailored solutions for this unique project,” Bradbury said.
“Being engaged for the mechanical, electrical, fire, hydraulics and vertical transportation services, together with specialised Green Star, sustainability, acoustics and fire engineering consultancy, has allowed NDY to take a holistic view of the tower – and the broader precinct – and accommodate innovative, cost-effective and sustainable long term designs."
Tower 1 is part of the broader Capital Square precinct which also comprises of a 30 storey residential tower with a 120 room hotel at the lower levels, a 40 storey prestige residential tower, and a vibrant public square that will accommodate retail, a crèche, gymnasiums, spa, swimming pools and restaurants.
In a bid to make it one of the most energy efficient and highly rated buildings in Western Australia, Tower 1 is also targeting a 5 Star Green Star – Office As Built v3 rating and a 5 star NABERS Energy rating.
