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.

This is a reminder that the Board of Directors of IBPSA is seeking nominations for the 2015 Class of Fellows. The IBPSA membership grade of Fellow recognizes individuals who are:

A member who has attained distinction in the field of building performance simulation, or in the allied arts or sciences, or in teaching of major courses in said arts and sciences, or who by way of research, simulation code development, original work, or application of building simulation on projects of a significant scope, has made substantial contribution to said arts and sciences, and has been active in the field for at least ten (10) years”.

The IBPSA Board of Directors elects new Fellows on a two-year cycle, culminating with recognition at the biennial Building Simulation conference, which will take place in Hyderabad, India next year.

Nominations may be made by IBPSA members other than the nominee. The application package will include details of the nominee’s qualifications, a CV, supporting letters, and other relevant materials. The details of the nominee’s qualifications shall include summaries of accomplishments in one or more of the following categories: industrial leadership, research, simulation code development, application of building simulation on projects of significant scope, educational leadership, and significant technical contributions to the allied arts and sciences. The application form and instructions are available on the web at:


Nominations must be submitted via email to the Chair of the Awards and Fellows Committee, Pieter de Wilde, at The deadline for nominations is 31 January 2015. Please contact Pieter de Wilde to discuss a possible nomination if required.
