February 6, 2020 BY ARBS

The ARBS 2020 Speaker Series is in the final stages of development and if this sneak peek is anything to go on, we are in for an incredible series with some of our industry’s top names presenting on a diverse range of HVAC&R and building services topics, updates and trending issues.

The ARBS Speaker Series runs in conjunction with Australia’s only international air conditioning, refrigeration and building services trade exhibition, ARBS 2020. Each session will provide attendees with invaluable learning opportunities and the opportunity to accrue Continuing Professional Development (CPD) Points.


Infrastructure Without Tears: How to transition from commercial to industrial contracts without losing your shirt

by Melissa Kirby & Murray Walls, Sharpe & Abel & RMIT University

This will be a unique presentation for ambitious HVAC&R companies and commercial building services contractors to learn both the theory and the practice of transitioning from commercial to industrial infrastructure projects.

With increased quality assurance, monitoring and evaluation, as well as complex risk management, HVAC&R companies and commercial building services providers are looking for guidance when considering upcoming industrial infrastructure opportunities. This seminar will seek to provide these answers as presenters will share case studies from the complex infrastructure world – the good, the bad, and why these projects can turn sour. Topics to be covered include the differences between commercial and infrastructure contracts whilst exploring the patchwork of contracts, legislation and relationships that mechanical, refrigeration and commercial building services contractors need to navigate to find long-term success.


Decommissioning of existing HFC based, air-cooled refrigeration plants and replacement with NH3 DX based solutions

by Stefen Jensen, Scantec

A truly informative seminar which will detail the decommissioning of several existing HFC based, air-cooled refrigeration plants servicing a refrigerated warehouse and replacement of these with a central, low charge, dry expansion, NH3 based refrigeration plant.

The session will draw on comparisons between the recorded energy performances of the new DX, NH3 system and those of the previous HFC based systems. The analysis will review the supply authority records of the electrical energy consumed by the HFC plant and the consumption records generated using the SCADA system of the new ammonia plant, as well as an economic comparison between NH3 DX and an equivalent transcritical CO2 system.


The efficiency of air movement systems – Improve your ROI by focusing on upgrading your HVAC&R systems

By Susanne Lohmann & Thomas Heine, ebm-papst

European markets such as the Nordic region and Germany have pioneered the use of higher efficiency air movement systems and driven down the usage of electricity in housing and building stock. However, HVAC continues to use the most energy in commercial buildings and this is the area where energy reductions benefit the bottom line the most.

This seminar will outline the new technologies and improvements that have been made on the European stage and shares tips and lessons learnt to enable Australasian designers to improve their systems. Examples will be provided of building upgrades on a typical high-rise in Melbourne. It will also explore the options for fan upgrades in commercial buildings as stand alone or in combination with upgrades of other HVAC systems such as chillers, cooling towers, VAV systems and controls.


The Future of NABERS Energy

By Corine Mulet, National Australian Built Environment Rating System (NABERS)

Over the last 20 years, NABERS has achieved world leading results – including a 40% drop in energy use for buildings that have participated in the program over 10 years. Today, the future of NABERS Energy project is looking at how NABERS will adapt to achieve the same results over the next 20 years. This informative seminar will discuss emerging sector-wide trends that are being considered which include:

– Rise of net-zero carbon building design: Net zero carbon buildings are highly energy efficient and fully powered from renewable energy. This project considers how NABERS can recognise and reward buildings using zero emissions energy sources.

– A decarbonising grid: Considering what amendments NABERS should make across all its energy rating tools, over what timeframe, to ensure rating results remain relevant over the next decade and beyond.

In this session, NABERS will speak about the findings of the project to date, proposed solutions, impacts to ratings, future plans and how participants can input into the project.


Cold Hard Facts: An Annual Update

By Michael McCann & Peter Brodribb, Expert Group

The update to Cold Hard Facts will be revealed in this much anticipated session which will review the annual updates with a focus on changes to the bank of refrigerants in Australia. This review is expected to provide the annual rates of change in adoption of new technology and new refrigerants, data and trends that will enable improved forecasting of demand for HFCs against the Australian commitments to phase down HFCs under the terms of the Montreal Protocol.

As the market introduces and employs increasing non-HFC refrigerants that are not required to be reported at the point of importation, capturing data on imports of pre-charged equipment and on consumption of bulk gas, will require active industry participation.

The Department of the Environment and Energy has employed The Expert Group to produce the report. And given Cold Hard Facts is widely recognised as the most comprehensive inventory available of the Australian HVAC&R sector, this will be a session not to miss.


Seismic Restraint of HVAC explained

By Jordan Bartlett, Eurofast

This session will address Part B1 Structural Provisions of the National Construction Code of Australia which calls up AS1170.4 without exception, therefore including Section 8 Parts and Components which can apply to restraint of Building Services.

The presentation will detail why restraints are required and who can design them, when section 8 applies to a building and what the listed exemptions apply to. The content will assist participants to improve tendering, ensure an audit trail and implement an integrated approach.


HVACPRO – AI: MPC for Optimisation of HVACR Systems with Hybrid Energy Sources including Renewables

By: Chirayu Shah, Subbu Sethuvenkatraman & Mark Hooper, Conserve It, CSIRO & Echuca Regional Health

With distributed energy use in buildings becoming increasingly common, systems now need to meet building energy needs. Historically commercial buildings have utilised chilled water storage and the building thermal mass as storage to avoid electricity peak demand charges. However future outlooks envisage building HVAC systems to employ a combination of storages systems, energy sources and chillers to optimally meet building energy needs.

This session will outline an artificial intelligence-supported model predictive controller (AI-MPC) framework using a high-level model to generate predictions of system load and resources to minimise operation costs. AI methods will be applied to continuously learn and update the system models based on feedback from measurements and to generate predictions and define optimal trajectories.

The AI-MPC will focus on addressing challenges existing in the framework including reliable and efficient estimation of future status as required for multiple factors in the system and joint optimization of the entire system.
