Charter Hall Group and Cbus Property have been awarded a six star rating for their 171 Collins Street asset in Melbourne, for the second consecutive year.

171 Collins Street is the only building in Australia to have achieved this National Australian Built Environment Rating System (NABERS) rating, making it the nation’s most waste-efficient building – with an impressive 74 percent recycling rate over consecutive 12-month periods.

Waste initiatives implemented at 171 Collins Street include daily on-site measuring of all building waste, separation of bins by tenancy and floor in order to track waste on a micro level, and biannual waste audits. There are also specialist recycling activities involving paper hand towels, e-waste, coffee cups, batteries and printer cartridges.

Monthly waste monitoring is reported to all tenant customers to allow them to see how they measure up in terms of waste. This is helped by ongoing waste management education with tenants, utilising the building’s waste and contamination data to provide actionable recommendations and solutions.

NABERS Waste Ratings measure the percentage of building waste recycled, which can include additional recycling initiatives, such as those for e-waste, coffee pods and printer cartridges. Implementing sophisticated recycling methods and achieving a high rating is dependent upon key factors, including collaboration and community, environment, education, tenant engagement, and collecting and analysing building data.

The six star rating reflects the co-owners’ combined focus on sustainability and strategic asset management at 171 Collins Street. The asset management team partnered with tenant customers, including BHP, Evans and Partners and VicSuper, to implement a variety of innovative recycling and waste management measures.

The building’s waste and contamination data is also monitored daily by environmental consultancy Ausnviro to identify any trends and areas for improvement. This real-time monitoring provides critical reference points and a holistic overview as to how the building is tracking.

Charter Hall’s regional portfolio manager, Nicole Ward, says the significant NABERS result is due to the dedication and hard work of the team at 171 Collins Street, including Knight Frank, Ausnviro and the building’s tenant customers.

“We’re proud to have achieved the highest NABERS Waste rating in Australia for the second consecutive year,” she says. “This shows how a collaborative, innovative and data-led waste management strategy can deliver an industry-leading sustainable workplace, evidenced by what the team has achieved at 171 Collins Street.

“While water and energy may usually be the focus when it comes to sustainable commercial buildings, waste is an important part of a building’s eco system and can be a significant contributor to sustainability performance. With our partner Cbus Property, we’ve taken a long-term approach to waste management at 171 Collins Street and the commitment and support of our valued tenant customers has been extraordinary so far.”

Cbus Property’s CEO, Adrian Pozzo, congratulates the on-site management team for its ongoing efforts in bringing waste reduction and recycling to the fore of 171 Collins Street’s building operations. “The program implemented at 171 Collins shows how an effective recycling program can be delivered, and the importance of engaging positively with our tenants and having access to quality, timely data to monitor progress.

“We will continue to learn from this success and apply the knowledge to our other investments, as part of our broader vision to reach a 75 percent recycling rates across our commercial office portfolio by 2022.

“171 Collins sets an impressive new benchmark with its six star NABERS Waste, six star Indoor Environment Quality and 5.5 star NABERS Energy ratings. It is now being powered by 100 percent renewable energy through our involvement in the second Melbourne Renewable Energy Project, facilitated by the City of Melbourne, making it one of the most sustainable commercial buildings in Australia, if not a world leader in sustainable design practice.”
