Sydney Opera House


Creating a sustainable future for an architectural icon.

When it comes to challenging retrofits, few can match the task of helping the Sydney Opera House win a prestigious 4 Star Green Star rating from the Green Building Council of Australia. 


Completed in 1973, Australia’s most iconic structure required a series of energy efficiency improvements in order to see it become one of the few World Heritage buildings to be awarded green certification.


Two key areas to be addressed was the generation of internal hot water and the ability to remove heat from the building.




Rheem was asked to take part in the ambitious project in late 2014, due to its extensive array of hot water system expertise. 

Not surprisingly, the task wasn’t a simple one.


The Opera House represents a unique proposition, in that it bears a constant cooling load due to the lighting and people loads. The building draws water from Sydney Harbour through large capacity heat exchangers and uses it to transfer heat  (generated by chillers, which keep the internal spaces at the desired temperature) to the harbour. So the key question became: how could the heat generated by the chillers also be used to improve energy efficiency and make a powerful case for green credentials?

A unique dual benefit solution


Rheem commissioned the installation of two Rheem Thermal water-to-water hot water heat pumps deep within the Opera House structure in July 2015. Both units were designed to extract heat from the air conditioning condenser water loop at high efficiency for use in heating the building’s hot water storage capacity.


In carrying out that task, the condenser water is cooled, so the heat pump not only provides high efficiency hot water but assists with the task of chilling, or dispersing heat out of the building. When you combine the efficiencies in hot water and chilling, the Rheem Thermal Heat Pump is operating at a COP of above 7.0, making the system a crucial component of the energy efficiency improvements which led to the 4 Star Green Star performance rating.

The project was unique and required considerable direct involvement by Rheem in the application design. The expertise Rheem Thermal has in water heat pump design, and particularly around water-to-water-type heat pumps, proved to be invaluable.
