Radevski Coolstores in the Goulburn Valley Victoria is a major supplier of apples and pears to Coles. It undertook a $1.15 million upgrade of 2 cool store systems, to allow the plant to operate on ammonia as a refrigerant, and to use condenser fan speed control (using variable speed drives) to further improve performance. The results were significant: one site recorded 60% reduction in its maximum electrical demand, and the upgrades will cut the company’s energy costs by 25%.
Aquatic Centres use an enormous amount of energy. But with efficiency measures, YMCA Spark pilot site Peter Krenz Aquatic Centre managed to cut electricity use by 8.5% and identified opportunities to save a further 20%. This Aquatic Centre found that by being more energy efficient and making some smart energy investments, they could have a reduction off their energy bills of at least $30,000 per year.
The ‘Watts in Your Business’ project conducted by Apple and Pear Australia Ltd completed energy audits of 30 packhouses and orchards Australia-wide. This fact sheet shows how refrigeration changes can cut energy use and save money.
The average small-medium retail business can use 80,000 kilowatt hours (kWh) of electricity a year. Makin’ Groceries in Brunswick Victoria saved on the energy costs of running its walk-in cool room by implementing simple actions including replacing door seals, turning lights off when the cool room is unoccupied, storing produce as soon as it arrives to prevent heat gain from ambient air, regulating temperatures between 3 and 4°C, and keeping the cool room three quarters full (this is more efficient than running it half full).
Case study prepared by Team Catalyst showing how the design of a community centre in a retirement village in western Sydney might change if the building had been designed to comply with the 2019 version of the energy efficiency provisions in Section J of Volume 1 of the National Construction Code, rather than the 2016 version. The case study focuses on the building fabric provisions. The case study was completed in early 2018 using an early draft version of Section J 2019 and does not fully reflect the final version published in February 2019.
The Boarding House project at Roselands New South Wales is still in design development stage, and consists of 9 sole occupancy units and a communal lounge. Out of the 9 units, 6 are proposed to be two storey structures, with a mezzanine bedroom. The 3 remaining units and communal lounge room are proposed to be single storey structures. The project is a class 3 building under the NCC, located at Roselands, inner western Sydney which falls in NCC Climate Zone 5.
Mitchell is a small town servicing landholders in the western downs district of south west Queensland. Mitchell business owners were offered a level 2 energy audit to gather information on the typical energy use by their business and to gain an understanding of potential energy efficiency opportunities across the project area. Mitchell Butchery participated in the audit activity.
The owners of a black Angus breeding and fattening operation on a small, pastoral property north west of Roma Queensland, were using dated refrigeration units to cool and store beef as well as other household perishable goods. An officer from Queensland Murray-Darling Committee’s (QMDC) Energy Efficiency Information Grant project was engaged to conduct an audit of the property’s energy use to ascertain whether savings could be achieved.
