Energy efficiency improvements - Kith and Kin

Date

Townsville’s Kath and Kin Association provides opportunities for people with psychiatric and physical disabilities, acquired brain injuries, and people with disabilities.

Energy assessment - Footscray Community Arts Centre

Date

At the Footscray Community Arts Centre in Footscray, the site includes a heritage listed building and warehouse, and an outdoor amphitheatre and lawn. The site’s annual electricity spend it $27,000 (from an annual usage of 130,000 kWh) plus around $3000 in natural gas cost (from an annual usage of 200,000 MJ). An energy assessment identified this could be reduced by $11,000 per year (39% of annual spent) by implementing the suggested opportunities. 

Tank insulation - McLaren Vintners

Date

As the winemakers at McLaren Vintners well know, energy is used at every step of the wine making process.  Refrigeration is a big energy consumer, making insulation a crucial component in saving both money and energy. An audit found that if McLaren Vintners insulated all of its tanks (currently, 56% of 202 tanks are insulated), they could save over $45,000 a year on their annual electricity costs. The payback period on the outlay is only 4.5 years. 

Dust extraction system upgrade - Downs Aluminium Casting

Date

Downs Aluminium Casting is a small, family owned and operated non-ferrous foundry located in Toowoomba, Queensland. The company produces aluminium castings for the construction, power and marine industries. In 2013 it installed a 27kW solar PV system. An audit shows other improvements – including by installing a variable speed drive to the dust extraction system - could improve the company’s energy efficiency. 

Energy assessment and efficient lighting - ABC Castings

Date

ABC Castings is a privately owned non-ferrous casting foundry located in Sydney’s Riverwood. It supplies castings to niche markets in mining and rail. Energy assessments showed savings of over 50% could be made by retrofitting existing lighting with light emitting diodes (LEDs) or induction fittings. Not only would this save on energy, but the change would reduce waste, and provide better directional lighting for focused jobs. Installing skylights was also shown to save up to 30% on lighting costs. 

Variable speed drives on irrigation pumps save energy - Sunfruit Orchards

Date

At Victoria’s Sunfruit Orchards, 3 of its 4 pumping stations represent 25% of the business’s total electricity consumption.  An audit showed that installing a variable speed drive onto the irrigation motor in the orchard, at a one-off capital cost of $3700 would save $1510 a year with a payback period of 2.5 years.

Energy efficiency practices in the automotive industry - Victoria and Tasmania

Date

The Victorian Automobile Chamber of Commerce (VACC), the peak automotive body in Victoria and Tasmania, rolled out the Automotive Energy Information Program in October 2012. The program was designed to identify and promote energy efficiency practices and resources through the distribution of practical information for the industry to reduce costs and adopt energy efficiencies. This series of case studies were developed through program funded energy audits conducted by an energy specialist across a diverse range of businesses. They cover a range of topics including:

Energy efficient design and possible savings - Willowdale Community Centre

Date

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.  

Proposed building upgrades - Roselands Boarding House

Date

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.

Potential energy savings - Stockland Green Hills Shopping Centre

Date

This case study prepared by Team Catalyst showing how the design of a shopping centre in Maitland New South Wales 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 uses the Greenstar verification method (JV2) newly added to the 2019 version of Section J. 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.
