Energy Saving Case Studies
Monash University cut electricity usage by 30% with EcoSwitch
Monash University Clayton Campus in Victoria conducted a two month pilot study in 2012 to determine the cost-effectiveness of installing the EcoSwitch® throughout the university’s office workstations*. With just one EcoSwitch per desk, they reduced energy consumption by 30%!
Other key outcomes from Monash University’s pilot study include:
- 87% utilisation of the EcoSwitch® reduced total energy consumption measured against BAU (Business As Usual) by around 30%
- 100% of the study respondents were using the product at least “most days”
- the EcoSwitch® saved around 10% more electricity measured against BAU than the leading SPC (Standby Power Controller) approved for IT environments under the VEET (Energy Saver Initiative) program in Victoria
- Feedback responses from the study group included “love it”, “easy”, “simple” and “want to use some at home”
- The majority of people used the EcoSwitch® because they held a positive attitude towards its implementation and ability to save power.

Monash University Pilot Study Details
A statistically representative mix of office staff workstations were selected that typically employed a Compaq desktop or a Dell notebook computer, a monitor and a standard CISCO IP Phone.
Post installation surveys were conducted after 2 months in which an 87% average utilisation rate was achieved. With this utilisation rate, based on the 12c/kWhr the estimated annual energy savings by installing 1200 EcoSwitches to a 50/50 mix of these workstations is projected to be around 53MWhr. This represents a return on investment in around 18 months.
Raqibul Hassan, Office of Environmental Sustainability, Monash University, said “Even if we had a utilisation rate of only 50% we would see a return on investment in just 2.7 years, which we are more than happy with.”
