The following information is designed to assist speakers prepare and deliver their presentations at AIRAH conferences.
The following are examples of abstracts which were submitted and subsequently selected for previous AIRAH conferences.
The abstract forms part of the technical paper, and should be self-contained and as explicit as possible, setting out the topic being covered and the principal conclusions reached.

What can simulation tell us about building tuning?
Building tuning has long been recognised as a critical method for the improvement of the performance of existing buildings. However, the estimation of the potential benefits of HVAC control adjustments is difficult using normal industry calculation methods. Fortunately, with recent advances in building simulation models, it is possible to test a number of common tuning strategies to determine their effectiveness in achieving energy savings.
Based on a generic mid-sized VAV building, the authors have used an IES simulation model to assess the impacts of a number of common control algorithm adjustments, including dead band and proportional band adjustments for VAV terminals, fan control and supply air temperature control, economy cycle, minimum outside air control and chilled water reset. Results are repeated for Sydney, Melbourne Brisbane and Canberra to show the way impacts change with climate.
Combined scenarios are used to show that the difference between best practice and poor control can range as high as 50% to 90%, demonstrating the fundamental importance of control. Sensitivity to control is considerably greater in milder climates.

Title: Yarra Valley Water Mitcham Office Refurbishment
In the global market there is increasing focus on how to effectively upgrade B and C grade buildings stock. These buildings are typically outside CBDs and don’t attract the major tenants that are driving improved environmental performance in the CBD office market. The recent upgrade of Yarra Valley Water’s Headquarters in Mitcham, offers useful insights into the opportunities to improve the performance of B and C grade buildings. The YVW offices upgrade included full refurbishment of the office spaces including a new interactive team-based work environment, and a complete replacement of the building services to include a stand-alone tri-generation system. The tri-generation system was installed based on a precinct approach linking three of the main buildings into a site wide energy network.
This project represents a major milestone for YVW in their aspiration to improve their NABERS energy rating and overall accommodation standards. YVW initially approached Arup to assist them in identifying ways to optimise their environmental performance. Following a detailed feasibility study considering options including; ground source heat pumps, co-generation, and solar PV, Arup concluded that a precinct tri-generation system would offer an optimum way to achieve YVW’s objectives. The tri-generation system design was based on detailed energy modelling to optimise the selection of the plant which resulted in two propitiatory co-generation units being twinned with an absorption chiller. The precinct energy system has been operational since April 2014, providing electricity, heating hot water and chilled water across the site. Initial modelling indicated that YVW would reduce their overall site greenhouse gas production by 33%, and early trends are already showing an improved energy performance.
This case study presents lessons learnt regarding the importance of feasibility studies, challenges for authority approvals for embedded generation, technical difficulties around optimising the system performance and the benefits of taking a precinct approach.
The following are general guidelines regarding the preparation and delivery of your presentation.
- All PowerPoint presentations must use the relevant conference template. Please email email@example.com for a copy.
- Submit your PowerPoint presentation to the Conference Organiser by the nominated deadline.
- Your presentation should not have been presented at any other event, unless it contains new information and has been tailored for the audience.
- Corporate speakers should introduce their company only briefly, and should declare any conflicts of interests at the beginning of their presentation.
- If, due to unforeseen circumstances, you are no longer able to present at the conference, please notify AIRAH's Conference Organiser immediately.
- If you wish to be put in touch with any of the other conference speakers, to discuss the content of their presentation, please contact AIRAH.
- Advise AIRAH of any AV, catering or any other special requirements you have, well-ahead of the conference.
During the conference
- You will be provided with information as to when arrive at the venue, ahead of your presentation. Generally, this will be in the meal break before your session. Please be on time.
- On arrival, ask for the Conference Organiser, who will assist you and introduce you to the session chair and the AV technician.
- Bring a copy of your presentation on USB. Any video or media files should be provided as separate files.
- AV technicians will be available throughout the conference to assist with pre-loading presentations onto conference laptops before the session, and checking the formatting is correct.
- During the meal break, ahead of their session, speakers will be asked to test their presentations, the microphone and the remote control to familiarise themselves with the equipment and ensure they are comfortable.
- Please ensure you do not exceed the time limit for your presentation. A 3-minute warning bell will sound.
- Group questions and answers will take place at the end of each conference session, unless otherwise stated.
- AIRAH will provide each delegate with a conference proceedings folder, which contains the technical paper of each speaker. Where a speaker does not provide a technical paper, AIRAH may ask the speaker to provide a copy of their PowerPoint presentation instead.
- AIRAH will also provide delegates only with a non-editable PDF copy of each speaker's presentation following the Workshop. If your presentation contains sensitive information, please let the Conference Organiser know to arrange an edited version to be made available instead.
Download the technical paper guidelines.
The conference venue will be equipped with the following:
