Greenhouse Gas Reduction Initiatives
Murdoch University is renowned for its environmental and sustainability focussed courses. In the last few
years the administration has taken measures to ensure that it is practising what it preaches by seeking to
minimise the ecological footprint of the organisation. One way that it is going about doing this is by
reducing the carbon emissions associated with its energy use.
In December 2008, Murdoch installed a 192 panel 26kW solar photo-voltaic array on the north facing roof
of the Murdoch campus main library. This was at an expense of 250,000 Australian dollars and made
Murdoch the largest private electricity generator in Western Australia. The system produced an average of
130 kilowatt hours per day. The university continued its commitment to reducing its carbon foot print by
installing an additional 171 panel 30kW system in December 2009. This more than doubled the generating
capacity to a total of 56kW, producing an average of 280 kilowatt hours per day, or enough to power 45
average Australian homes. It is expected that the combined system will reduce greenhouse gas emissions
by about 53 tonnes a year.
From a monetary point of view there were
more cost effective options available for
reducing Murdoch's greenhouse gas
emissions but the rationale behind
installing a photo-voltaic system was that
it would be a symbolic gesture to inspire
people entering the campus and would act
as an educational tool for staff and
students.
The upgrade to the system in 2009 has
also included an updated website that will
allow students, staff and members of the
community to log on and check in real
time how much energy the individual and
combined systems are producing. Data
from the newly installed monitoring
equipment for ambient and panel
temperature, wind speed and solar
radiation will also now be shown on the website. It is intended that the system will be utilised by students
in the university's Energy Studies programme. Murdoch's Environmental Programme Manager Caroline
Minton stated that “The website will be an excellent tool for all of our students because they will be able to
track the performance of each system with the variables and ambient conditions”.
Unfortunately, the 56kW system still only produces about 1% of the campus’ energy demand. The
university therefore decided to purchase 15% of its electricity as 'green power' from the state electricity

provider. The 'green power' scheme allows consumers to purchase electricity from certified renewable
energy sources at a premium rate. It was intended that the percentage of 'green power' used by Murdoch
be raised to 16% this financial year but the service provider 'Synergy' is struggling to find the necessary
generating capacity to do so. This increased demand for Green energy may also provide opportunities for
increased green energy production locally, encouraging further growth in the local sustainable energy
sector.
Murdoch's decision to employ Environmental Programme Manager, Ms Caroline Minton has been
instrumental in the administration's ability to implement these forward thinking environmental initiatives.
Further emission reduction initiatives currently recently implemented by Murdoch include:
• A detailed analysis of the University’s carbon and greenhouse footprints
• Recycling 400 twin sets of fluorescent light fittings containing polychlorinated biphenyls (PCBs) and
replacing them with safer and more energy-efficient lights.
• Development of software to better track and manage the University’s vehicle use and fuel
consumption
• The addition of three secure bicycle compounds and numerous new bike racks to encourage people
to cycle to campus.
• The drafting of a university energy policy focussed on achieving energy efficiency and greenhouse
gas reductions through comprehensive monitoring, annual reporting, green building design and
stakeholder education.
The recent initiatives by Murdoch demonstrate the organisation's renewed commitment to act as a
catalyst for positive social change and its desire to remain at the forefront of sustainable practice in the
tertiary education sector. Murdoch will continue to seek new and innovative ways to reduce its ecological
footprint, inspire its students and further the development of a sustainable global community.
