Achieving Low Energy Existing Commercial Buildings in Australia Report

Date

Energy Ministers agreed on the Trajectory for Low Energy Buildings in 2019. This is a national plan that aims to achieve:

  • zero energy and carbon ready buildings in Australia
  • the National Energy Productivity Plan target of improving energy productivity by 40% by 2030

The report identifies 6 options to achieve this.

The report is by the former Department of the Environment and Energy and the COAG Energy Council.

Timing peak energy use - P. Savio & Co. pack house and cold storage

Date

An assessment of P. Savio & Co. (Savios) pack house and cold storage showed where energy use and costs could be reduced. Savios facility in Pozieres Queensland produces and packs approximately 4000 tonnes of apples per annum. It is a large facility with 14 cold storage rooms controlled by a refrigeration system that utilises 3 large ammonia compressors ranging from 22 kilowatt (kW) to 37kW in size. From May 2013 to February 2014 the pack house consumed just over 435,000 kilowatt hours (kWh) of electricity at a cost of almost $95,000 (excluding GST).

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 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.

Energy assessment and equipment upgrades reduces energy use - Majors SUPA IGA

Date

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
