At the IBPSA Special Interest Forum in Sydney on July 14th, Dr Paul Bannister will be talking on supply air temperature control.  We asked Paul what sorts of insights we might expect from the talk.
 
“It’s been a bit of a voyage of discovery preparing the work for this talk “said Dr Bannister. “and I’d have to say, I don’t think it’s over yet.  To put this in context, the findings of the works so far show a reduction of 8% in energy use relative what I would have considered good to best practice.  That’s no small beer!”
 
So what role can simulation play in this? “The work so far has taken scores of simulations, which gives a level of insight that just can’t be achieved by fiddling with the metaphorical dials on a real building” say Paul. “That said, I think it’s increasingly possible to see where the balance between theory and practice is likely to play out in real-world implementation; all along I have been looking for something that gives optimum performance theoretically but can actually be implemented with real controls in a real buildings – and still work.”

It’s heartening to see that in spite of a senate gridlock that makes Australia’s senate issues look like a rather dainty garden party, the US has managed to pass legislation looking towards major steps for energy efficiency in the commercial buildings sector.  Who knows, in time they may even catch up with our NABERS and CBD schemes!

The Chartered Institute of Building Services Engineers (CIBSE) have a Building Simulation Group who host regular events in the UK, and publish all of the presentations online. Previous events have included topics on CFD,  zero carbon buildings, indoor environmental quality, and operational energy modelling. The next event is on 14th May this year, and is titled “Linking Building Design Performance with BIM” – keep an eye out for the presentations on the website:

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.
