The project has achieved a 5 Star Green Star Design rating and is […]
This week, international travellers began arriving in Melbourne again, and are re-entering Victoria’s revised hotel quarantine facilities. Numbers have been capped at 800 per week and will increase to 1,120 per week on April 15 provided that key recommendations are addressed – including many relating to ventilation. Focus on airborne transmission It has been almost […]
The ASHRAE Epidemic Task Force has released an updated, unequivocal statement on the airborne transmission of SARS-CoV-2 (the virus that causes COVID-19) in buildings. “Airborne transmission of SARS-CoV-2 is significant and should be controlled,” says the statement. “Changes to building operations, including the operation of heating, ventilating, and air conditioning systems, can reduce airborne exposures.” […]
The Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH) has released the program for its Refrigeration 2021 Conference, scheduled from May 17–18 in Melbourne. Keynotes Thomas Lund of Danfoss Industrial Refrigeration, Bruce Nelson, M.AIRAH, of Colmac Coil Manufacturing, and Thomas Frank of Refolution will headline a list of more than 20 speakers and four […]
The US-based Air Conditioning, Heating and Refrigeration Institute (AHRI) has released a test report that examines fire safety issues related to A2L (lower flammability) refrigerants. The fire service requested that data be developed to identify hazards to fire service personnel when responding to fire events in occupancies with the new refrigerants. Undertaken in cooperation with […]
The Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH) has held its board elections for the 2021–2023 term and voted in Paul Jackson, F.AIRAH, as the new president. He will succeed Ian Harwood, F.AIRAH, whose term ends in May. Also appointed to the AIRAH board were Bryon Price, F.AIRAH, and Liza Taylor, M.AIRAH, both […]
The Australian Building Codes Board (ABCB) has developed a discussion paper about the potential for building manuals to address long-standing problems with inaccurate and incomplete building information. Issues with building documentation were highlighted in the Building Confidence Report, published in 2018. It recommended that each state and territory require a comprehensive building manual to be […]

Twelve American states have filed a federal lawsuit against President Joe Biden for his executive climate change order, alleging that he lacks the statutory and constitutional authority to dictate specific values for the “social costs” of greenhouse gases for regulatory programs administered by the federal government. Biden signed executive order 13990 on his first day […]
Global chemistry company and refrigerant producer Chemours has announced a project to significantly reduce emissions of HFC-23 at its Louisville, Kentucky (US) manufacturing site. HFC-23 is a potent greenhouse gas with a 100-year global warming potential (GWP) of 12,400 – many times greater than most refrigerants used today. It is a by-product of producing R22, […]
NSW has announced a $750 million program to promote low-emission industries and drive the state towards its 2050 net zero target. Energy Minister Matt Kean says the Net Zero Industry and Innovation Program is about co-investing with industry to reduce carbon emissions and develop low-emissions technologies for the future. “NSW was one of the first […]
A new report prepared by the Expert Group for the Department of Agriculture, Water and the Environment lists the most common faults identified in residential and commercial refrigeration and air conditioning equipment. It also gauges the impacts of these faults and highlights how routine maintenance could significantly reduce electricity use, refrigerant leaks and emissions. The […]
A new report has highlighted the possible environmental and human health risks posed by some HFOs – the newest generation of synthetic refrigerants – breaking down in the atmosphere.
