Unit 3: Energy Production and Use
Introduction to the Origin energy calculator part 1 activity guide
Estimated duration: 30 minutes Aim •
To introduce student to the Origin energy efficiency calculator as an energy auditing tool
Outcome By the end of this session, student will be able to: • Understand of the types and quantities of appliances in their own homes; • Have an overview of the energy auditing process
CD Rom Origin Energy Home Energy project (available from Origin – see below) Or
Click on the energy efficiency calculator at www.originenergy.com.au/2103/Residential‐Efficiency • • •
Computer Internet access or CD Rom Student worksheet (included below)
Note that an alternative calculator is available from the Environment Protection Authority, on their website and as a CD ROM. However, there are additional computer system requirements for this calculator (at the time of writing) which might create difficulties in using this resource if your computers need updating. We recommend you try the calculator out on the computers the students will use to ensure they work correctly. This calculator is available from www.epa.vic.gov.au/GreenhouseCalculator/calculator/default.asp.
Activity Description 1. Ask one of the students to act as a volunteer for a class demonstration showing how to use calculator. 2. Load the energy efficiency calculator and follow the prompts. Page 2 of 4
3. Show the students how the calculator works by moving through the different rooms and clicking on the icons. Emphasise that this is a demonstration and that they will need to find out the kinds of systems there are in their own homes to complete their personal audit. For example, many students will not know whether their hot water system is gas or electric, or they may have trouble identifying the type of heating system. 4. Show the students the graphs being generated in the reports section. This includes a table of costs per quarter and per year for each appliance. It also includes a pie chart showing how much energy is being used in each area as a proportion of the total energy consumption. 5. Get the students to take the worksheet home and fill it in. They will enter this information into the calculator in Unit 4. Note: There is excellent material for teachers available as part of the Home Energy Project from Origin Energy at www.originenergy.com.au/hep. Support materials are also available at www.originenergy.com.au/education.
