ARBS 2020 PROJECT EXCELLENCE AWARD FINALISTS

NEWTON PLANT INSTALLATION – TRI TECH REFRIGERATION AUSTRALIA & MAYEKAWA AUSTRALIA

This project is the first installation of Japanese OEM Mayekawa’s ammonia/CO2 NewTon system in the southern hemisphere. NewTon systems are renowned in Japan and globally for their modular design, low ammonia charge, next generation compressors and inherent safety as a CO2 cascade and recirculation platform. Of the approx. 2000 NewTon plants installed since 2008, none had been built in Australia. As the first plant of it’s type in Australia, this is significant in that it will instill a greater degree of confidence in end users and contractors seeking to use pre-packaged and low ammonia charge CO2 cascading systems like the NewTon, but who were previously reluctant to do so as it had not been done locally before.

 The NewTon systems installed in this project also use semi-hermetic, permanent magnet motor, internally compounded and economised ammonia compressors which are also a first in Australia. This project therefore is the beginning of an installation base for such compressors which will allow more of them to be installed. This is significant as semi­ hermetic ammonia compressors allow for simpler, safer and lower charge ammonia plants, particularly in smaller applications where there is a growing need to transition to low GWP solutions, but where there have been limitations associated with the cost and/or safety of using ammonia.

 

THE WOOLWORTHS ENERGY MANAGEMENT CENTRE – BUENO & WOOLWORTHS

In every industry, the latest technology concepts are changing the way we do business. Facilities Management of the Built Environment is no exception. However, in many cases the application of technology has not progressed past initial trials or single site concepts. This project demonstrates the successful application of the latest in data and analytics technology – at considerable scale with commercially viable returns on investment.

The Woolworths Energy Management Centre (EMC) was designed and built to use data and analytics to optimise the energy consumption across 980 Supermarkets across Australia.

Using a combination of 4,000 existing IoT devices, 6,500 newly installed sub meters, 7 different OT communication protocols, and purpose built cloud and network architecture, connection was made to the key energy intensive assets at each site.

Consuming 350 million granular data values per day, bespoke analytics were developed for Refrigeration, HVAC and Lighting, which make up over 85% of a sites energy consumption.

The application of analytics at this scale has delivered benefits in both energy reduction and operational value, as a new data driven operations approach becomes the norm.

Analytics at this scale has not been achieved elsewhere and is a first in the Refrigeration and HVAC space.

Delivered 2 years early and 25% under budget, it is an excellent example of a results orientated partnership between Bueno and Woolworths.

 

177 PACIFIC HWY – FREDON

More clients and businesses are seeking cheaper, energy-efficient HVAC solutions and 177 Pacific Highway introduces a solution for the future.

177 Pacific Highway is a 31-storey commercial building in St Leonards built by CPB Contractors. At 195m tall and having a net lettable area of 40,000m2, the project demonstrates that it is possible for buildings of any size to have an economical and eco-friendly HVAC system without traditional green energy systems such as green power, chilled beams and Cogen solutions.

Fredon brought its trademark project management and design expertise to deliver the building’s energy targets, achieving a 5.5-Star NABER rating and 5-Star Green Star rating in 2018.

The project stands out as it exhibits conventional mechanical solutions being altered and customised to increase energy savings. A low-temperature VAV system and two AHUs were used to control the whole building, with customised solutions in the chilling plant to maximise savings and minimise energy costs.
