IBPSA-Australasia is keen to improve the collaboration, knowledge sharing and networking opportunities for our members and are asking for your feedback. After the first extremely successful forum on CFD – it is clear our members are keen to see and get involved in more. So could you take 10 minutes to fill in our survey.

The survey will be open until 5pm, 24 April 2015

IBPSA – Australasia Survey – https://www.surveymonkey.com/s/63NJQJD

The Building Codes Assistance Project (BCAP) is asking assistance of ASHRAE members in completing a survey about the current use of energy modeling software by design professionals.  While modeling at any stage provides valuable data on how much energy a building will consume, energy modeling during the conceptual stage influences design decisions, promotes cost-effective energy savings, and facilitates energy code compliance in the later phases of the project.

More design teams are choosing to pursue energy code compliance using the performance path as opposed to the prescriptive path.  The performance path requires the use of computer simulations of operational energy usage.

BCAP will use the results of this survey to identify and remove barriers to the widespread use of building energy modeling software, so that even more design professionals will have the option of choosing the performance path.  Feedback will better prepare professionals for the evolving demands of an industry increasingly concerned with energy usage.

To access the survey go to https://www.surveymonkey.com/s/WXZWTSY.  The survey closes April 30.

Based on the outcome of the election held in late 2014, the new IBPSA Board of Directors is now in place.  Half of the elected Directors will serve for 1 year and the rest for 2 years (term lengths were set by random draw).  Half of the Board will be elected each year from now on,  starting in the fall of 2015.

Thank you for your support of IBPSA.

On February 10th 2015, IBPSA Australasia held its first special interest evening, which aims to get more people in the building performance simulation industry talking to one another and discussing hot topics. This session was focussed around computational fluid dynamics, or CFD, in the built environment and hosted three guest speakers; Nicki Parker (IBPSA Australasia Vice President) from AECOM, Jason Gaekwad, formerly of Aurecon, and Andrew Ooi from the University of Melbourne. The presentations varied from performance in data centres, to computational wind engineering, and complex physics in double skin facades.

Over 20 attendees participated in the event in Melbourne, with several people signing up for IBPSA membership. There was some great feedback and a big appetite for these events in the future. IBPSA Australasia’s next event will be held in Sydney in July, and focus on energy modelling. It is the aim of the committee to engage with members on a more regular basis, running local networking and learning events. Hopefully this will raise the standard and profile of building simulation in the Australian construction industry.

Come along to hear our three guest speakers talk about their views on the use of computational fluid dynamics in the industry and how they use CFD in their day-to-day work. Each guest will present on what they believe are the key tricks of the trade, providing case studies of where CFD can really add value both commercially and in a research environment.


Nicki Parker (AECOM)

Nicki works on a wide range of projects from pedestrian comfort studies through to large scale energy strategies, however one of the most interesting sectors she works in is mission critical data centres. Nicki will introduce some of the different types of cooling she has simulated using CFD, leading on the main focus of her presentation – what happens during cooling unit failure?

Andrew Ooi (Uni of Melbourne)

Andrew will discuss turbulent flows driven by gravity and how this can affect heat transfer in the built environment. His presentation will concentrate some of the formulas that industry have used and how recent findings and data have provided insight into why these formulae might not be applicable when buoyancy effects are important.

Jason Gaekwad (Aurecon)

Last but not least, Jason will present on the use of CFD in wind engineering, covering the fundamentals of atmospheric boundary layer flows, as well as the interaction of wind with buildings and the urban environment. Different applications will be discussed, along with potential issues in using CFD for this type of analysis.
