AIRAH Building Simulation Procurement Guidelines – February 2014
Building simulation is a fundamental component of contemporary sustainable building design. Whether driving early design decisions, establishing compliance with regulations or certification schemes, meeting tenant energy performance requirements or simply proving the effectiveness of a proposed design, simulation is a powerful tool used on many new-build and refurbishment projects.
However, developers, architects, building owners, facility managers, and managing agents often encounter difficulties when engaging a consultant to complete a simulation. Common problems include confusion over the type of simulation required, a lack of understanding of the outcome needed and the steps necessary to achieve that outcome, a poorly defined modelling scope creating difficulty in comparing quotes, and a lack of confidence in the skill or quality of the simulation.
The AIRAH Building Simulation Procurement Guidelines will provide advice on these topics for those intending to engage a consultant to complete a building simulation. Types of simulations to be covered include, natural ventilation, façade optimisation, HVAC optimisation, NABERS Energy, Green Star (energy, daylight, thermal comfort and NCC JV3. The guidelines will not cover CFD, tenancy energy consumption, water consumption modelling or any residential modelling.
The AIRAH Building Simulation Procurement Guidelines may be downloaded from the Technical Resources webpage.

HVAC&R Career pathways
AIRAH is developing model career pathways for Building Services (mechanical) and Refrigeration engineers as part of a process to help identify skills gaps in the HVAC&R sector in Australia.
Building Services Engineer
The model pathway for Building Services Engineer (mechanical) has been released. The term ‘mechanical engineer’ is a broad description that covers roles beyond the HVAC industry, whereas ‘building services engineer’ more specifically refers to mechanical services such as air conditioning, heating and ventilation.
The model career pathway defines job titles, roles, tasks, skills and knowledge requirements of mechanical engineers working in the building services sector. The pathway progresses through four stages:
- Level 1, the graduate mechanical engineer or engineering officer level
- Level 2, mechanical engineer
- Level 3, senior mechanical engineer
- Level 4, principal engineer.
The report offers recommended tasks and knowledge and skill requirements for each job title.
The Australian Bureau of Statistics will recognise 'Building services engineer' as an official occupation under the specialisation 233512 Mechanical Engineer from the release of ANZSCO Version 1.2, scheduled for May 14, 2013. AIRAH undertook two activities to achieve the ABS recognition. The first was a survey of industry practitioners, the second an evidence-gathering exercise to show there are at least 300 individuals working in the occupation.
Job analysis under way. Contact firstname.lastname@example.org

AIRAH Industry Summit 2013 meeting report - March 2013
AIRAH convened the 2013 Summit 12 months after the first Summit hosted by AIRAH. At that time the industry appeared to be relatively ill prepared for the introduction of the carbon equivalent levy and was facing structural changes and pressure on a number of fronts. Following the first Summit AIRAH commenced the work of preparing an industry road map with the aim of identifying the most important elements of a critical path, and the resources required to support all sectors of the industry make as rapid a change as possible to a low--‐emissions HVAC&R industry.
The 2013 Summit was convened to update the broader industry on the progress with this work and to get direct responses to a number of issues and on the process that AIRAH had developed to author the roadmap.
The 35 members of the industry and government who attended the day endorsed both the process and the content of the road map so far and on the basis of the positive support for the project AIRAH will continue in developing this strategic plan for change.

AIRAH HVAC&R Industry communiqué to Government - May 2012
The introduction of the Australian Government’s Clean Energy Future legislative package on July 1, including the carbon-equivalent levy on refrigerant gases1, will present many challenges and opportunities to Australia’s heating, ventilation, air conditioning and refrigeration (HVAC&R) industry, and to the hundreds of thousands of people it employs. Our industry is estimated to be responsible for systems and equipment that contribute as much as seven per cent of Australia’s greenhouse gas emissions. The overwhelming majority of these emissions stem from energy use and only a very small proportion is due to refrigerant leakage. It has become apparent that the introduction of the carbon-equivalent levy on refrigerant gases will result in a number of overlooked and negative outcomes.
Since the introduction of the legislation late last year this has become a serious industry concern. On March 29 2012 the Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH) convened an industry Summit. This event brought together all industry groups. The Summit focused on formulating a best practice response to the Clean Energy Future legislative package and identified a range of potentially unacceptable effects from the introduction of the carbon-equivalent levy on refrigerant gases.
This communiqué outlines the serious concerns of the industry and proposes a number of urgent actions needed to address and avoid unwanted impacts from the introduction of this legislative package.

AIRAH Industry Summit 2012: Transitioning the Australian HVAC&R industry to a low emissions future
In response to the new “carbon tax” and the related carbon-equivalent price (CEP) that will be levied on some HFC refrigerants AIRAH organised and facilitated an industry summit to assist key stakeholders identify the issues, solutions, potential barriers and essential actions that should be associated with this policy implementation.
Some of the major points proposed at the summit include:
- Industry needs help to transition to a low-emission future. It is not sufficient for the government to impose new charges and expect market forces to resolve all the issues. Government and industry need to work together to ensure that the required policy outcomes are achieved.
- Revenues generated by the refrigerant CEP should be directed back to the industry to fund the required governance structures, industry communications, licensing and enforcement programs, training and education programs and end-user initiatives.
- A joint industry-government council should be formed. This council should be given the resources and ability to respond to issues and adapt to changing circumstances caused by the implementation of the carbon tax.
- More robust and proactive licensing and enforcement regimes must be implemented to prevent inappropriate, unsafe, fraudulent or criminal activity.
- Improved communications and trusted technical information urgently needs to be provided to industry to ensure that the policy is implemented correctly and does not give rise to serious safety issues and other perverse outcomes.
- New standards, codes of practice, training and education resources must be developed to underpin the transition to a low-emissions HVAC&R future
This report outlines the detailed discussions and conclusions agreed at the industry summit. It will be used to inform government of the industry issues and to help develop an industry roadmap for the transition period.

Energy Simulation harmonisation work
AIRAH Proposal for change - National Construction Code series - Metabolic rates for specification JV - January 30, 2012
This proposal relates to a modification of the requirements of the existing Specification JV to replace the specified metabolic rate (heat gains from people) figures with a reference to accepted national and international data sources for design metabolic heat rates.
This proposal forms part of a larger project to harmonise the specified default inputs of the three energy modelling protocols in use in Australia.

Energy modelling harmonisation project - Seeking information on metabolic rates for energy modelling - January 2012
AIRAH has been working with the Department of Climate Change and Energy Efficiency (DCCEE), the Australian Building Codes Board (ABCB), NABERS and the Green Building Council of Australia (GBCA) on a project to harmonise the default inputs in the energy modelling protocols of NCC JV3, NABERS commitment and Green Star GHG guide.
AIRAH has proposed that the metabolic rates used in the building/system design should be allowed to be used in the energy modelling protocol. AIRAH propose that the current specified metabolic values in specification JV Clause 2 (a) (iii) (A) should be removed in favour of a reference to AIRAH, ASHRAE, ISO, and CIBSE data sets (this is intended to reduce the amount of rework required for energy modelling).
The data sets are:
• AIRAH DA9 (1998) – Load Estimation & Psychrometrics
• ANSI/ASHRAE 55 (2010) – Thermal Environmental Conditions for Human Occupancy
• ISO 8996 (2004) – Ergonomics of the thermal environment - Determination of metabolic rate
• CIBSE Guide A (2006) - Environmental Design
This may be too many references to include in the NCC and there is a further option to reduce these four references to the AIRAH and ASHRAE data sets only. The question to industry is “Which source of metabolic rate data do you use in your designs” (heat load calculations) AIRAH, ASHRAE, ISO, CIBSE or some other source?

HVAC High Efficiency Systems Strategy (HESS)
HVAC High Efficiency Systems Strategy - Guide to best practice maintenance & operation of HVAC systems for energy efficiency - January 2012
It is hoped that this Guide to Best Practice Maintenance & Operation of HVAC Systems for Energy Efficiency will be a change accelerator and encourage those working with maintenance & operation of HVAC Systems to have a sharper focus on improving energy and water effi ciency.
The advice in this Guide is relevant to typical Heating Ventilation and Air Conditioning (HVAC) Systems that are installed in commercial offi ce type buildings. It is applicable to existing buildings – both old and new, small to large and different grades from premium grade city CBD to rural. The advice given in this Guide may also be applicable to buildings other than commercial offi ce type buildings. The Guide is also applicable to future buildings that are being designed – it addresses important topics to consider during the design and documentation stages of new projects.
This Guide identifies and recognises the importance of existing Australian and International standards and guidelines for maintenance of HVAC Systems and attempts to avoid the repetition of material already published. Existing publications cover factors for consideration when setting up maintenance contracts including statutory requirements for occupational health and safety, maintenance schedules for reliability, occupant comfort and contract administration. For the maintenance of HVAC Systems in Australia, the availability of the AIRAH application manual DA19 – HVAC&R Maintenance is acknowledged. This Guide focuses on energy and water effi ciency aspects of maintenance and operation, complementing the advice and maintenance schedules already published in DA19.

Download the Review of technology options for sub‑metering and wireless data-logging systems suitable for application to older HVAC systems
The measures - HVAC High Efficiency Systems Strategy - March 2007
The installed base of non-residential HVAC systems in Australia are estimated to:
Consume 9% of electricity produced in Australia and produce more than 3.6% of the total Australian greenhouse gas inventory (>21Mt CO2 pa);
Depending on the building type and use, be responsible for between 40% and 60% of all energy used in non-residential buildings;
On average create more than 55% of electrical demand recorded in CBD buildings during peak demand periods;
Involve cooling towers that consume billions of litres of water per annum across Australia;
Service approximately 120 million m2 of buildings, are part of an industry worth about $7 billion per annum and employing at least 95,000 people.
A ten year strategy designed to improve the energy performance of HVAC systems was commissioned by the Equipment Energy Efficiency committee.
The resulting strategy has received widespread industry and stakeholder endorsement and has a target of improving the energy efficiency of the installed base of systems by 20% over the life of the strategy. If that target is achieved it would reduce greenhouse gas emissions by approximately 4Mt pa and save as much as $350 million in energy costs pa.
The strategy that has been designed addresses many non-technical barriers to efficiency while identifying and promoting highly efficient technical solutions, systems optimisation processes and creating the environment in which energy efficiency gains are valued, measurable and sustainable.
More than 20 separate but complimentary measures are proposed across eight priority areas, grouped under three broad strategic initiatives.
