In June 2016, 171 Collins Street became Melbourne’s first Premium Grade 6 Star NABERS rated office building. This milestone capped off several years of dedication by the entire project team as well as 171 Collins Street’s tenants in delivering and maintaining a truly green and sustainable building.
The building’s 6 Star NABERS rating, representing ‘world leadership’ in sustainable performance, has been applauded by the Green Building Council of Australia, with Chief Executive Officer Romilly Madew saying the building’s certification was “not just a mark of excellence in sustainability, but of quality.”
171 Collins Street was completed in June 2013 and is home to tenants including BHP Billiton, Wood Group, Evans & Partners and Myer Family. Designed to achieve a 5 stars NABERS energy rating, the challenge was to try and improve the 5 Star NABERS rating to 6 Stars whilst maintaining premium conditions to occupants and complying with all lease commitments. In order to provide further context, the difference between 5 Star and 6 Star NABERS energy ratings requires a 50% reduction in carbon emissions.
Fine tuning of the services was crucial to maximise the efficiency of the installed plant and equipment. This targeted improvement in operational performance required active and focused management of 260 smart meters, the BMCS, Access Control and the cogeneration system. With the benefit of these “smart tools”, the following processes were applied to fine tune the performance of the building services and minimise energy consumption.
