Ultraviolet germicidal irradiation (UVGI) using electromagnetic radiation in the UV‑C wavelength band of 200–280nm can prevent the reproduction of microorganisms. Several factors related to UV fixtures, HVAC layout and the resulting airflow flow patterns can affect the performance of upper‑room UVGI applications.

Well, it has been a busy few weeks, and as I put pen to paper for this column AIRAH has just held the Future of HVAC 2023 conference, along with the Building Physics Forum and Big Data and Analytics Forum, which were all held at Marvel Stadium in Melbourne, writes Paul Jackson, F.AIRAH.

International Women in Engineering Day once again reminds us of the gender disparity in STEM (science, technology, engineering and mathematics). Some progress has been made in addressing serious barriers for attracting and retaining women in STEM occupations

Chris Wright, M.AIRAH, is a director of HVAC&R contractor TCM, based in Moonah, a northern suburb of Hobart.

This paper examines the challenges associated with removing natural gas from hospitals and transitioning to all-electric systems. It emphasises the unique energy requirements of hospitals and the need to prioritise patient care and safety over energy efficiency.

Ecolibrium chats to Brisbane-based Litmas laboratory manager, whose specialty is IAQ.

Convention, intention, and what’s next

Opinion: Learning is for everyone – all the time, writes Professor Gayle Avery.

Raising the profile of the HVAC&R building services industry is a goal that runs across all AIRAH’s activities.

By the time you are reading this almost half of 2023 will have flashed by. It’s incredible how time speeds up as you get older. How is the year progressing for you?

For Simon Witts, M.AIRAH, it’s the complex projects and designs that keep him going. We chat with the national division director, engineering for VA Sciences, based in Melbourne.

Recognising performance that goes above and beyond doesn’t always have to be expensive, writes Dr Gayle Avery. But it does have to be executed properly and appropriately.

How to ensure that budding HVAC&R building services professionals get the support they need? AIRAH firmly believes mentorship is the way forward.

It’s one thing to manage a business when times are good, but what do you do during difficult times – such as in an economic slowdown?

High-temporal-resolution precipitation data of the past along with other data of weather elements are required for applications in the design and simulation of built environments. However, the available data of precipitation is either low-resolution, e.g., daily, or not long enough to produce reliable and climate-responsive results for built environment applications.

Joe Biviano, M.AIRAH, may have left behind the hurly-burly of the workaday world, but he’s still a loyal member of the Institute.
