in commercial buildings around Australia,” he said. “The outcome of this comparative simulated study provides valuable information to engi- neers and technical staff engaged in HVAC de- sign and the monitoring of how systems actually
operate in practice.
“Building managers and others who are inter-
ested in ensuring that HVAC equipment oper- ates efficiently and at the lowest energy cost will benefit from information derived in this study.”
Using data from the simulation of a typical 10 storey commercial building in Sydney, the study provides predicted energy intensity for each of the three systems.
Foundation board member, Ashak Nathawni, said specific readings are likely to vary a little at other locations, but the findings of the study pro- vide an important starting point for analysis and decision-making in other locations.
“For reasons of energy efficiency, a further im- portant outcome of the study is to draw attention to the need to ensure the HVAC equipment in- stalled is the correct size for the building it serves.
“Far too often HVAC installations are over- sized, particularly in central chilled water plant. The study underscores the important role that proper commissioning of plant plays in its opera- tional efficiency.”
With the generous financial support of ARBS Exhibitions, each year $50,000 is being added to education and re-
search in the industry by the
ARBS Foundation.

THE ARBS EDUCATION AND RESEARCH FOUNDATION HAS RELEASED THE RESULTS OF ITS LATEST SPONSORED RESEARCH WHICH IS A COMPARATIVE STUDY INTO AIR DISTRIBUTION SYSTEMS.
THE FOUNDATION JOINED with Team Cata- lyst to prepare the world first comparative study in dynamic simulation analysis of three types of HVAC air distribution systems.
They are: passive chilled beam, underfloor air distribution, variable air volume.
Foundation chair, Ian Hopkins, said he is not aware of any building simulation study that compares these forms of air distribution.
He said it was never the intention of the study to determine if one system was superior to another.
“Our intention was to compare the operational outcome of the systems which are most prevalent
HyChill factory fire
Products from the HyChill range.
THE COUNTRY FIRE Authority (CFA) and Metropolitan Fire Brigade (MFB) were called to the HyChill Australia factory in Melbourne last month to deal with a fire that originated in the warehouse.
Canterbury Road in Kilsyth was shutdown while the fire was brought under control and an employee was taken to Alfred Hospital.
HyChill issued a statement in mid-Octo- ber which said: “One of our valuable staff has sustained medium level burns in this incident and is currently successfully re- covering in the hospital. Our best wishes for a speedy recovery are with him and his
family. We are truly grateful to all the Emergency Services men and women, in- cluding fire-fighters, police, paramedics and others who bravely fought to bring the fire under control and minimise the im- pact on us and neighbouring businesses. While the exact cause of the fire is not fully clear at this stage, we know that the fire damaged the office and warehouse build- ing, but that the main storage and cylinder filling facilities remain intact.”
Recovery plans were introduced imme- diately to ensure continuity of supply for customers. ✺
