Event Details


The Great Chilled Water Debate 

Since time immemorial, or at least since the introduction of mechanical cooling into buildings, there have been passionate arguments about the most efficient and effective method of generating and circulating chilled water in buildings.

In the Great Chilled Water Debate, you will get viewpoints and drivers from design consultants, contractors, energy efficiency practitioners and building owners discussing the merits of:

  • Primary-secondary vs Variable primary flow
  • Series counter-flow vs normal parallel arrangement
  • Common control and maintenance issues associated with each

While the ultimate answer to the age-old question may continue to elude us, the Great Chilled Water Debate will deliver some light hearted but robust discussion on the merits and potential pitfalls of this hot topic.




Dr Paul Bannister - Paul has an international authority on energy efficiency in the built environment and is well known for his role as the primary technical author of the NABERS Energy and Water ratings.

 baBarry Abboud - Barry has actively participated in the HVAC industry for more than 20 years, and has worked on many projects across Australia and New Zealand. Most notable projects include Barangaroo; the largest series counter flow project in Australia with direct sea water heat rejection, and Sydney Opera House, a complex plant utilising series counter flow and series parallel arrangements combined with heat recovery and indirect sea water heat rejection. Barry also worked on the Darling Harbour Live development, delivering an optimised combination of a low load series counter flow pair combined with two main load pairs, with variable flow chilled water and condenser water pumping arrangements. Barry currently holds the position of National Sales Manager, Building Technologies and Solutions, at Johnson Controls Australia.
