Type 2 Energy Audit for a medium sized Disability Care facility in NSW identifies potential annual energy savings of $32,000


The disability care facility consisted of Main Office, Learning Centre, Cafeteria and Auditorium.   


The objectives of the energy audit were to:  

  • Evaluate the overall energy consumption of the site; 
  • Evaluate what the energy is used for; 
  • Identify and assess options where savings can be made; 
  • Estimate costs for viable savings opportunities; and 
  • Provide a list of recommended options complete with energy and cost savings, greenhouse gas reductions and budget cost to implement. 

EMS personnel spent two part-days on site, met with key personnel and service contractors and provided two Wattwatcher monitoring devices which were installed on the two main air conditioning systems. A third temporary electrical logger was installed on a third air conditioning system. 

EMS analysed the data from the monitoring devices and estimated the energy consumption of the various major equipment and areas of highest energy use. 

EMS analysed potential energy saving opportunities then contacted suppliers to provide budget prices for various potential energy upgrades. 


The buildings incorporated a mix of new and old equipment and had an overall estimated Nabers rating of 5.5 which was above the average for office buildings. However, EMS still managed to find 12 electrical opportunities with a total estimated saving of $21,000 pa and a payback of just 2.9 years.  These opportunities were principally associated with improving air conditioning system controls and some lighting upgrades.  An additional 36 kW of solar panels could save another $10,960 pa with a payback of 7 years. The longer than normal solar payback was the result of substantial shading issues. 

The total identified potential electricity savings of 102 MWh pa represented a 42% reduction in current electricity consumption and a 3 month payback on the cost of the energy audit.
