Target 'Outstanding' 

The long-term energy savings, reduced environmental footprint, and occupant well-being and productivity benefits affirm the project's sustainability credentials.


Target 5 stars

NABERS is a simple, reliable sustainability rating for the built environment. The Design for Performance Agreement forms the basis of a rigorous project energy strategy by acting as a shared, tangible target for all parties involved from planning and design through to construction and operation to deliver an energy efficient, high-performance office building.

Smart tech monitoring energy performance

Power sockets indicate when energy is being supplied from renewable sources, encouraging use when energy is green, and enable the likes of computer monitors and printers to be turned off during out of office hours.

Measurable Energy
Smart power solutions’s solution is designed to eliminate ‘Small Power’ waste, that is energy not required by devices that are plugged in or directly wired, such as printers, AV equipment, chilled/hot water taps, monitors, and heaters, which are often left fully on or in standby mode overnight. According to’s analysis, up to 40% of total electricity usage in most commercial office buildings can be attributed to this type of ‘Small Power’ energy use. 

Water monitoring & management

Using artificial intelligence a team of cleantech innovators have created an ultra-affordable and easy-to-use IoT sensing solution, with the potential to completely transform the efficiency and environmental impact of the global water monitoring and management sector.  Their technology will enable customers to become more sustainable by saving water, reducing carbon emissions as well as saving costs and simplifying compliance with statutory water monitoring obligations.
