‘Watching brief’ on airborne COVID-19
The World Health Organization (WHO) has acknowledged growing concerns surrounding the airborne transmission of the coronavirus, following the publication of an open letter addressed to the Geneva-based agency, but says more evidence is still required. Since the beginning of the pandemic, the organisation has advised that the virus is primarily spread through large respiratory droplets […]

The cold reality of energy poverty
The average Australian would probably not describe theirs as a cold country. However, working from home during the COVID-19 pandemic has brought to light how many Australians are struggling with their heating and energy bills. An article on the Sydney Morning Herald website states that on average, 42 people in New South Wales end up […]

Opinion: Mario Balen on national licensing
HyChill General Manager Mario Balen, Affil.AIRAH, shares his views on national HVAC&R licensing in Australia. The HVAC&R trade is widely regarded to be under-recognised, poorly regulated and, on average, inadequately trained. Attempts have been made for many years to address some, if not all, of those shortcomings, with little success so far. The end result […]

Free webinar on integrative design
Energy efficiency is traditionally assumed as a host of separate technologies to be added in order of increasing cost – the more energy saved, the greater the marginal cost of that saving. Yet as physicist Amory Lovins would counter, designing buildings, vehicles, and factories instead as whole systems could save several times more energy at […]

Cold chain highlighted on World Refrigeration Day
World Refrigeration Day (WRD) is celebrated annually on June 26, the birth date of Lord Kelvin, after whom the absolute temperature scale is named. This year, the day will be dedicated to cold chain technology, and its vital role in food security and in preserving public health and wellbeing. Designated as the world’s biggest celebration […]

Opinion: Can HVAC systems spread COVID-19?
By Craig Roussac, M.AIRAH. All buildings are created for people, and building owners must ensure they are safe. But unfortunately, as with most things in life, there is no guidebook setting out the “ideal” way to achieve that outcome. This is especially true in a pandemic. Over recent days, research has been published in the journal Nature that […]

Opportunity for work-day building maintenance
With many buildings across Australia currently empty, AIRAH board member and Country Leader, Integrated Technologies – Digital Solution, at Johnson Controls Australia, Ura Sarfejoo, has highlighted the opportunity for facilities to consider upgrades to improve building efficiencies, without disruption to tenants. Sarfejoo believes that with the current low occupancy rates in buildings, the maintenance of […]

Plants and IAQ: an ongoing debate
Late last year, doubts were cast over whether plants actually improve indoor air quality (IAQ) after new research was published in Nature’s Journal of Exposure Science and Environmental Epidemiology. Ronald Wood PhD, BSc, from Innovative Plant Technology, has taken issue with the study in an article published in Ecolibrium. He says that a “literature review with […]

Passive House hits prime time
As Australians struggle through another sweltering summer, more families are trying to lower their power bills through better energy efficiency in their homes. A recent report on ABC’s 7.30 delved into exactly how much Australians could be saving if they had Passive House homes. Passive House (also known as Passivhaus) is a low-energy and high-comfort […]

Are you polluting your office air?
A team of engineers at Purdue University has been conducting an experiment to identify indoor air contaminants and ways to control them. The study involves thousands of sensors being installed in an office space called the Living Labs, at Purdue’s Ray W. Herrick Laboratories. It uses an array of sensors to precisely monitor four open-plan […]

Concerns over cold-housing deaths
Better Renting has released a report that estimates low-quality housing causes approximately 140 cold-related deaths per year in the ACT. The report is titled Unsafe as Houses: Cold-housing deaths in the ACT, and compares temperature data with statistics on monthly deaths from 2009–17. The report uses data from the Australian Bureau of Statistics (ABS) and […]

Five low-hanging fruit of HVAC&R
The time has come to herald the sustainability solutions offered by HVAC&R, rather than focus on its challenges. That’s the message from Andrea Voigt, Director General of the European Partnership for Energy and the Environment (EPEE). As Europe swelters through one of its hottest summers on record, cooling in the form of air conditioning is […]
