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.
