Developing a framework for delivering quality towards a sustainable built form future
Peter Phillips, F.AIRAH Member ASHRAE (Ret), Fellow AIRAH (Ret)ABSTRACT Delivering successful, high-quality, sustainable, future-proofed, built-form projects requires planning and coordination of complementary factors. This includes broad-based statements and detailed...

Development of a whole-house energy rating tool for new housing
In 2019, Australian energy ministers agreed on the need for the Trajectory for Low Energy Buildings (the Trajectory). One of the key aspects in the Trajectory for residential buildings is to expand the Nationwide House Energy Rating Scheme (NatHERS) to offer nationally accredited whole-of-home (WoH) tools to enable compliance requirements in the National Construction Code (NCC).
Streamlining electrification in support of decarbonisation
Our industry has increasingly focused on the electrification of building utilities coupled with low-carbon electricity to support the global decarbonization effort. Examples include the University of California’s system-wide ban on the use of on-site fossil fuel combustion in new construction and major renovations, and the City of Seattle’s recently passed measure to prohibit the use of natural gas for space heating in new construction and major replacements of heating systems in commercial buildings, as well as for water heating in new hotels and
large apartment buildings. This column presents an approach to integrating the production of domestic hot water with an electric heat-recovery chiller plant as a streamlined solution.
Feasibility study of wastewater energy transfer for an existing campus building cluster
The HVAC-related energy usage of a group of three existing buildings on a Canadian university campus (the “Cluster”) was simulated. Two scenarios were compared: (1) an ambient loop paired with conventional HVAC equipment (boiler plant and cooling tower), and (2) an ambient loop using wastewater energy transfer (“WET”). The study aimed to assess the feasibility of implementing WET as a heating and cooling method for cold-climate institutional buildings, as well as to measure the effects of WET implementation on energy usage, greenhouse gas emissions, and energy costs
Pushing the Boundaries of Net Zero in the Australian Outback
Using a hybrid of dynamic thermal simulation and detailed hourly spreadsheet calculations, the analysis identified design and operation strategies to size PV and batteries for various degrees of grid independence.
Optimisation of Economy Cycle Operation and Supply Air Temperature Control for VAV systems
In the future, many Australian HVAC systems may be required to deal with harsher environmental conditions due to more extreme climatic conditions and a push to increase population centres in more northern and central regions of the country.
Minimizing Transmission In High Occupant Density Settings, Part 1
By David Rothamer, Ph.D.; Scott Sanders, Ph.D.; Douglas Reindl, Ph.D., P.E., Fellow ASHRAE; Timothy Bertram, Ph.D.ABSTRACT In this first article in a two-part series, we review the current base of knowledge regarding transmission of COVID-19. After briefly introducing...
Exploring the potential of personal radiant cooling systems
In the future, many Australian HVAC systems may be required to deal with harsher environmental conditions due to more extreme climatic conditions and a push to increase population centres in more northern and central regions of the country.
Lessons for the future of Australian HVAC from Pilbara mining
In the future, many Australian HVAC systems may be required to deal with harsher environmental conditions due to more extreme climatic conditions and a push to increase population centres in more northern and central regions of the country.
Simon says
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. When did you first decide you wanted to be an engineer, and how did you get to where you...

The life aquatic
Students and academics from the University of Melbourne joined forces with industry consultants and local government representatives to explore achieving net zero carbon design for those most energy-intensive buildings: aquatic centres. The university’s Brendon...
Condair appoints new MD
Condair has appointed Virender Rana as its new managing director. Rana will succeed Ian Eitzen, Affil.AIRAH, who is taking on a new position in the company as senior technical adviser. Rana brings more than 20 years’ experience in the HVAC industry to the role....
Monitoring key to better IAQ
Reliable Controls has added its considerable support to the push for better indoor air quality (IAQ), in particular through monitoring. “Integrating IAQ sensing technology into your building allows you to collect building data that helps you optimise building...
Rewards program
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.You’d think that using rewards would be a cinch – just give someone some money or something else...
