699 Bourke Street and 644 Collins Street

Standing next to each other above Southern Cross station in Melbourne, both 699 Bourke Street and 664 Collins Street were built with sustainability front of mind. Each asset uses onsite solar power, purchases 100 per cent renewable electricity, and utilises smart technology that collects real-time data on the buildings’ performance so that Mirvac and its tenants can improve efficiency and effectiveness. In addition, each asset has an 80,000 litre rainwater tank installed on site to service toilets and urinal flushes. This helped both assets achieve a 4 star NABERS 2 Water rating following completion, commensurate with their design.

To maintain water performance, the facilities team has implemented a rigorous hydraulic maintenance contract that ensures fixtures, domestic hot systems and potable and rainwater tanks are regularly inspected for correct operation and leaks. The contract also requires that all water from tanks is used onsite rather than disposed before cleaning. Finally, cleaners are required to report on faulty equipment in amenities (such as taps, toilet and urinal flush systems), while security patrols are asked to monitor cooling towers and plant and equipment for any leaks
