Energy audit of computing equipment - Keep IT Simple

Date

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.

Energy assessment and LED lighting - QMDC Chesterfield tractors

Date

Located in Goondiwindi, Queensland Chesterfield Australia is an Agricultural and Construction Equipment company. The Goondiwindi site has both workshop and a retail spaces requiring specific lighting. During the Financial Years 2012/13, the facility consumed 119,984 kilowatt hours (kWh) of electricity, emitting 103 tonnes of carbon. An energy audit identified potential energy efficiency cost savings of approximately $6605 a year using light emitting diodes (LEDs) upgrades, with a payback period of just 2.2 years.

Energy audit - QMDC aged care facility

Date

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.

Installing fridge timers saves energy and money - Bottle King Liquor

Date

The average small-medium retail business can use 80,000 kilowatt hours (kWh) of electricity a year. This factsheet shows how one business, Bottle King Liquor, saved on energy costs to run its fridges. By installing fridge timers, the business saved $135 a year for the running costs of each of its 7 drinks fridges, a $950 annual saving that was paid back in less than 2 months.

Demand side efficiency: Savio Pack House and Cold Storage

Date

The 14 cold storage rooms at Savio’s, a fruit packing house in Queensland, are controlled by 3 large ammonia compressors, which an audit showed consumed over 435,000kWh (costing $95,000) in ten months. By avoiding demand changes which account for 40% of Savio’s total electricity costs, the business could save $5500 a year by shutting down equipment at certain times. 

Energy efficiency improvements - Alto Hotel

Date

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. 

Energy management - Falls Festival

Date

The Falls Festival is a 3 day music festival held across Australia. Organisers of the Tasmanian event, at Marion Bay, were interested in reducing its fossil fuels consumption, and the savings that come with that. Assessments showed the primary opportunity to save came with selecting the right sized generators: there are 26 generators on site and changed practices were able to cut 90 running hours of usage by powering them down at appropriate times, and by choosing the right generator for the job throughout the festival. 

Energy management - Capilano Honey

Date

At Capilano’s Richlands honey production facility, electricity and natural gas are the primary energy sources and input costs. Of the 18,000 gigajoule (GJ) (a cost of $580,000) used on site, 25% is used by thermal loads of pasteurisation and hot water generation. An assessment took into consideration upcoming business changes (the build of a new facility was pending) and advised Capilano about opportunities to save money on lighting, solar PV, thermal system insulation and heat recovery, and compressed air heat recovery.

Energy assessment and LED lighting - Caernarvon Orchard

Date

Caernarvon Orchard in Orange, New South Wales, produces and packs 4500 tonnes of apples and 800 tonnes of cherries per annum. About 5% of its annual electricity spend is on lighting (around $3400 pa). An energy audit found that replacing high bay lighting fixtures with light emitting diodes (LEDs) would save $2120 a year (from a one off investment of $5600). Savings would also come from using electronic lighting ballasts, and replacing fluorescent tubes.

Building Code Calculator

Date

The Australian Government commissioned the development of software to estimate the emissions reduction and energy savings arising from future changes to the National Construction Code.
