With a commitment to net zero by 2030 for all occupied real estate globally, benchmarking of our corporate offices is vital.
Committed to reducing our carbon and energy footprint, our team was keen to measure current energy use and emissions for six Colliers offices and subsequently develop tenancy improvement plans.
Our sustainability experts partnered with the New South Wales government's funding initiative to commission National Australian Built Environment Rating System (NABERS) Ratings and improvement reports for offices in North Sydney, Sydney Central Business District (CBD), Newcastle, Liverpool, Mascot and Parramatta. Determining their current ratings provided a cross-section of office performance against peers and a roadmap for tenancy specific energy reduction action plans.
The ensuing reports cited each office's energy consumption, energy and greenhouse gas intensity as well as scope 1, 2 and 3 emissions. They also identified what level of energy and emissions reductions would be required to achieve a 5.0 or 5.5 NABERS Energy Star rating, with recommendations on how to realistically achieve each sustainability target.
Through this study, we discovered our offices ranged from 2 to 6 stars, revealing the importance of standardizing our approach to energy efficiency for our offices. The team is now implementing energy efficiency improvements such as installing occupancy sensors, switching to LED lights, maintaining HVAC temperature set points within a certain range, and reviewing energy saving settings on all office equipment. In one year, the team will rate its offices again to measure improvements in a bid to hold ourselves accountable to positive change.
