At the Albion Budget Supermarket in Brunswick West Melbourne a public event helped provide funds for sustainability improvements. Called a ‘Carrotmob’, this event promises businesses a ‘mob’ of consumers in exchange for the business owner spending some of that additional revenue on sustainability improvements. The $700 raised at this event covered the cost of replacing half the supermarkets existing lights with more efficient T5 fluorescent tubes. In turn, that has saved the owners money. The supermarket is on track to save over $600 in electricity costs every year.
Newcastle French Hot Bread, a busy bakery and café in Newcastle in NSW, used an action plan to gradually implement the improvements suggested by a local energy assessor. Changes included maintenance and repair of seals on oven doors, using an off-peak timer for the electric hot water system, and separating lights to different circuits, allowing for zoning. A bill analysis also showed they’d been overcharged by their energy retailer: working via the Ombudsman recovered the business $30,000.
Major’s SUPA IGA has served its community for more than 100 years. The owners have implemented numerous energy efficiency measures including airlocking the store entrance - creating a thermal barrier, by installing a second door, reduces air exchange between external and internal areas of the store, and cuts the heating, cooling and refrigeration load. Upgrading the heating and cooling system - installing variable speed drives to the heat pump and upgrading the cooling tower to a compressed condenser with high efficiency fans to reduce energy input to energy output requirements and increas
Queensland Murray Darling Committee Inc (QMDC) completed an energy audit on commercial premises in Goondiwindi Queensland. Over the 12 months up until February 2014, the facility consumed 23,650 kWh of electricity, emitting 20.3 tonnes of carbon. An energy audit identified potential energy efficiency cost savings worth approximately $2,603 per annum with an average payback period of 1.7 years.
Queensland Murray Darling Committee Inc (QMDC) completed an energy audit on an aged care facility near Warwick, Queensland. The retirement home consists of single level accommodation buildings and the capacity to accommodate 40 residents. During the Financial Years 2012/13, the facility consumed 114,467 kWh of electricity, emitting 98 tonnes of carbon. An energy audit identified potential energy efficiency cost savings worth approximately $4,257 per annum with an average payback period of 3.1 years.
The Australian Government is delivering an additional $10.5 million in 2019–20 to improve the energy efficiency of Australian buildings.
The Alto Hotel on Bourke in inner city Melbourne aims to lead its field in energy efficiency practices. Changes are extensive and have included equipping air conditioning with inverter and moment sensor technology (an $8000 saving); finding ways to optimise heating in an heritage building (solutions include staggered stud wall systems, multiple layers of floor coverings, and heat reflecting, double glazed windows). This factsheet outlines many of the 4-star hotel’s initiatives to bring energy efficiency to the front of its business model.
The Australian Government is undertaking a review of the CBD program to assess its effectiveness and consider the case to expand the program to other high energy-using classes of buildings, such as shopping centres, data centres, hotels and office tenancies.
This case study describes University of Queensland’s (UQ) energy efficiency program at St Lucia Campus, where centralised energy management provided a better understanding of its energy use. UQ developed user-friendly online graphical user interfaces for staff and students of varying expertise to interact with energy data. The case study was developed as part of UQ’s participation in the Energy Efficiency Opportunities (EEO) program.
