The West Australian Commercial Property Report

Charter Hall’s innovative WorkZone complex is arguably now Perth’s “greenest” office building after being awarded Australia’s most up-to-date and prestigious 5 Star Green Star rating.

The two seven-level WorkZone buildings are the only buildings in Perth, and the first in Western Australia, to be awarded 5 Star Green Star – Office ‘As Built’ certification by the Green Building Council of Australia (GBCA) under version 3 of the rating. Version 3 is the most current and rigorous Green Star rating for commercial properties.

Developed by Charter Hall and built by Broad Construction Services, the $220 million WorkZone office campus in Perth’s CBD fringe represents Australian Excellence in sustainable construction and a new generation of A-Grade office space.

The WorkZone project reflects the aims of the City of Perth’s strategic directions paper Towards an Energy Resilient City, which outlines plans to make Perth more energy-efficient by reducing energy consumption and increasing the use of renewable energy.

Leighton Contractors became WorkZone’s major tenant when it moved into the WorkZone West building last October. Of the 28,000sq m of office space and ancillary retail space across WorkZone West and WorkZone East, just 6500sq m remains available for lease.

According to GBCA Chief Executive Romilly Madew achieving 5 Star Green Star Design rating required a commitment to innovation and a holistic approach to green building design.

“In taking the extra step with Green Star ‘As Built’ rating, Charter Hall has demonstrated that the sustainable design intentions were implemented during the construction process,” Ms Madew said.

Charter Hall Senior Development Manager Simon Hulett said features such as high-performance glazing, grey water recycling, advanced T5 zoned lighting, fully active chilled beam air-conditioning, an eight metre wide brise soleil shading screen and state-of-the-art energy and building management systems helped to achieve the coveted 5 Star Green Star v3 certificate.

“The result is not only WA’s greenest and most sustainable office building, but also a highly efficient and inspiring workplace that encourages collaboration and productivity. WorkZone has created a sense of community as well as a better work environment,” Simon said.

WorkZone benefits from abundant natural light, with glass elevators that add to the open transparent aesthetic, improved airflow and access to green open spaces. The two buildings offer large flexible floors that maximise its floor to ceiling glass to provide a high level of natural light penetration to the workplace, for a more refreshing work environment.

To encourage health and wellbeing, lifestyle facilities include generous bicycle storage, lockers, showers and change rooms.

A fully integrated fitout was undertaken with Leighton Contractors in Wokzone’s West building, with the interiors having a high level of transparency to help achieve the 5 Star Green Star rating.

The design includes a wide staircase void that connects the ground floor through to the top of the building, providing vertical vistas from one level through to the next, encouraging staff movement between floors and a high level of transparency to their clients.

The resulting connectivity promotes the office as one facility, rather than as a set of separate floors. Everything was addressed from indoor light quality – including setting workspaces to the perimeter and low-VOC surfaces. In addition, a high material efficiency was achieved, in part by constructing most joinery off site. Other green aspects include chilled beam air conditioning, energy-efficient whitegoods, low-flow tapware and Geca-accredited furniture.

Broad Group Holdings Managing Director Dean Goodliffe said his team worked closely with Charter Hall to deliver a high quality and flexible office space.

“Through rigorous pre-planning and positive interaction between contractor and client teams, the targeted 5 Star Green Star benchmark was successfully achieved for WorkZone,” Mr Goodliffe said.

WorkZone is just one of the commercial properties which make up Charter Hall’s $12.1 billion property portfolio. One of the largest owners and managers of commercial property in Western Australia, Charter Hall manages 28 assets across office, retail and industrial in the state, including a $1.82 billion office portfolio across 143,000sqm of office space across Perth.

The Group’s key Perth office assets include 109, 181 and 225 St Georges Terrace, WorkZone, Bankwest Place, 144 Stirling Street, Eastpoint Plaza and Sevenoaks. Its key customers include Leighton Contractors, Bank of Western Australia, Westpac, the WA Government, Coles Myer, Woolworths, Metcash and One Steel.
