Project Overview

Featuring prominent step-form architecture, 1 Collins Street at the “Paris End” of Melbourne’s famous tree-lined street has long been a desirable location for tenants with its views and access to the Treasury Gardens and Parliament House.


With no outside air capabilities to allow for energy efficient fresh air to replace chiller operation in cooler months, an innovative approach to plant optimisation has created a virtual economy cycle for a 17-level commercial office tower in Melbourne’s CBD.


Two new 800kW GeoClima variable speed, screw adiabatic air-cooled chillers were installed by Airmaster to replace original equipment that had reached end of life. The GeoClima chillers were selected for their ability to exploit the natural process of adiabatic cooling.
