VIRTUAL
Hybrid energy sources for HVACR systems
WITH DISTRIBUTED ENERGY use in buildings becoming increasingly common, systems now need to meet these requirements.
Historically commercial buildings have uti- lised chilled water storage and the building thermal mass as storage to avoid electricity peak demand charges. However future out- looks envisage building HVAC systems to em- ploy a combination of storages systems, energy
sources and chillers to optimally meet build- ing energy needs.
This session at ARBS will outline an artificial intelligence-supported model predictive con- troller (AI-MPC) frame- work using a high-level model to generate pre-

dictions of system load and resources to mini- mise 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 chal- lenges existing in the framework including reli- able and efficient estimation of future status as required for multiple factors in the system and joint optimization of the entire system.
Speakers include Chirayu Shah, general man- ager of Conserve It, Subb Sethuvenkatraman of the CSIRO and Mark Hooper of Echuca Regional Health.
Australia set new records for renewable ca- pacity installation and total electricity generat- ed from renewables in 2019.
The Clean Energy Regulator estimates that a record 6.3 gigawatts (GW) of new renewable ca- pacity was installed in 2019, 24 per cent above the previous record set in 2018.
Electricity generated from renewables is also estimated to have increased to a record 44 ter- awatt hours (TWh), 20 per cent above the previ- ous year.
The Clean Energy Regulator expects that 2020 will be the biggest year yet for electricity generation from renewables (both in absolute terms and year-on-year growth) with a forecast 26 per cent increase.
Based on Bloomberg New Energy Finance data, Australia invested $7.7 billion or $308 per person in renewable energy in 2019.

SEISMIC RESTRAINT OF HVAC
This ARBS session will explain the seismic restraint of HVAC and will be presented by Jordan Bartlett of Eurofast.
He will address Part B1 Structural Provisions of the National Construction Code of Australia which calls up AS1170.4 without exception, 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.
DWYER INSTRUMENTS HAS recently released the Series IEFB Insertion thermal energy meter.
The Series IEFB is a field-adjustable insertion thermal energy meter that uses electromagnetic technology to accurately and reliably measure fluid velocity and energy consumption.
The high accuracy IEFB is adjustable to fit pipe sizes from 4 to 10" (100 to 250 mm), while the standard accuracy IEFB fits pipe sizes 4 to 36" (100 to 900 mm). The energy meter is simple to install and incorporates a temperature meter and a calculator into a single unit.
The LCD display provides clear readings of the
meter’s values, including temperature and ener- gy consumption, making it ideal for installation on chillers, boilers, and other heating and cool- ing applications.
High measuring accuracy and long lifetime keeps annual operating costs at a minimum.
In addition, it offers several output options, in- cluding selectable BACnet MS/TP or Modbus RTU communications protocol over 2-wire RS-485 and standard analog, frequency, and alarm outputs.
Series IEFB can be hot tapped which makes it easy to install and remove the unit in an opera- tional system without any downtime.
