About this manual
This manual is a practical resource for students to assess home and school energy consumption and develop energy saving solutions. It aims to show students the connection between energy use, resource consumption and greenhouse gas emissions. It also aims to show how their lifestyle choices impact on the environment.
This kit enables students to conduct a comprehensive audit of home or school energy use. Auditing is the process of measuring and monitoring the use of resources. It allows you to effectively manage your environmental impact and provides a comprehensive strategy to encourage ongoing environmental improvements.
This manual can be used in the classroom or as a project for a school council or special interest group.
How to use it
This manual consists of 4 main steps for students to follow.
1. Project Book- Students should be given the take home Project Book at least 1-2 weeks prior to the planned CHAPPY computer session. Students can complete it individually or as part of a group.
2. CHAPPY- Once the Project Book is complete, students are ready to perform the computer analysis in CHAPPY. The information collected should provide the answers to all questions asked in CHAPPY, but remember, its OK if a student is unable to obtain all the information required. The program is set with the default values of an average NSW family and this will usually suffice.
3. Work Book- After generating results from CHAPPY and while still in front of the computer, students should work through the CHAPPY Workbook. This requires students to analyse different aspects of their energy consumption, interpret their results and provide energy saving solutions.
4. Optional School Audit- Once the home energy audit is complete, teachers may wish to organise a group of interested students to complete a school energy audit. The processes involved in this are explained in Step 4 of the manual. Alternatively, students could repeat Steps 1-3, inputting school data rather than home data into the CHAPPY program.
The benefits
Setting a practical model of teaching by example Increased awareness of environmental issues Potential dollar savings Experience in practical problem solving Potential to apply learning outside of school Opportunity to learn about new energy-related technology
Case Study - Newcastle City Council
Greater energy efficiency can be achieved through the implementation of common-sense initiatives, its as simple as changing to more energy-efficient light bulbs. The following are some of the measures taken by Newcastle City Councils green energy team, AMEIF, to reduce Councils electricity bill. Total cumulative energy savings achieved by Council between 1995 and 1999 amount to almost $600 000.
 
Turton Rd Works Depot Over the past 9 years, Councils Works Depot has reduced its energy costs by more than 60%. This was achieved through implementing a number of initiatives, including replacing incandescent light globes with a smaller number of high quality halide globes, installing light timers and replacing existing heaters and hot water systems with gas-fired units.
The total cost to Council over the 9 years is estimated at $100 000, with cumulativesavingsof $400 000
City Hall Newcastle City Hall contained 380 recessed downlights utilising 100Watt incandescent reflector lamps. These were replaced with 18Watt compact fluorescent downlight adaptors and lamps. The refit resulted in an 80% cut in energy consumption and paid for itself within 2-3 years.
Council Administration Centre The focus of efforts was the lighting systems within the centre. 40Watt fluorescent lamps were replaced with high efficiency tri-phosphor lamps, and the standard ballasts, which control the lamps, were replaced with efficient iron core fluorescent ballasts. An automated timing control system was installed to turn off lights outside work hours and a motion sensor system was installed in all toilets. These initiatives resulted in a 40% reduction in electricity bills.
Initial organisation
Identify project team, whether it be a class, special interest group or school council group
Appoint coordinator
Provide brief introduction to energy - its use, conservation and related topics
Decide on extent of involvement and develop action plan
Provide Pro ect Book to students

About CHAPPY
Sustainable development is the goal of governments, businesses and communities around the world. The concept encourages us to think globally and act locally, which means beginning at home with an analysis of the lifestyle and purchasing decisions we make as a family.
CHAPPY is a Life Cycle Analysis (LCA) model that enables students to calculate the environmental impact of their family. These impacts include the consumption of resource energy and water, atmospheric emissions of greenhouse gases, sulphur and nitrous oxides, and dust. These impacts are the result of the various lifestyle choices we make, including:
 Type and size of home  Home appliance type, size and use  Repairs, maintenance and refurbishment  Transportation  Recycling of household waste.
The results of the LCA are compared to a NSW average and are given in terms of total greenhouse gas emissions and resource energy consumption. These figures are related to the number of trees that would need to be planted to absorb your familys greenhouse emissions, and the length of time your annual energy needs would run a 100Watt light bulb.
Getting the most out of CHAPPY
In order for students to get the most out of CHAPPY, they will need to put effort into collecting the information required. The results are more effective if they can be specifically related to their own home.
Students will need at least 1-2 weeks to collect all the information from home and will probably require help from their parents. While in some cases it may not be possible to collect all the information required, encourage students to be as thorough as possible. Where information is missing from a family profile, default values for an average NSW family will be substituted.
Desired outcomes
This manualaimsto:
 Develop student awareness, understanding and appreciation of energy and its impact on lifestyle and quality of life.  Help link lifestyle choices with environmental impacts.
 Develop student understanding of energy management and conservation issues.  Develop an understanding of Life Cycle Analysis and the associated life cycle of energy use. It is expected that through use of this manual, students will developknowledgeand skillsin the following areas:  Researching and identifying missing information and drawing conclusions  Self-observation, self-analysis, structuring personal behaviour-change, and influencing the behaviour of others  Communication and effective presentation of information  Action planning and implementation  Analysis of facts and figures.
Project ideas
Describe the ways energy is used in a kitchen. Make a poster showing energy use in the kitchen. Select an energy source and show the purpose for which it is usually used. Discuss alternative energy sources. Solve the problems of a week without electricity. Analyse the energy sources used in transporting students and staff to school. Investigate the manufacturing steps of a product whose packaging was found in schoolyard litter. Identify times of the year and days when electricity use is highest in the school and discuss causes. Predict energy laws that might be needed in the year 2010. Investigate the impact on the Greenhouse Effect of using different structures and materials eg. in building a home. Organise a school roster system for daily reading/recording of gas, water, electricity meters. List 20 materials used to construct buildings - categorise as natural or processed, thermal conductors or insulators, energy intensive or benign etc.
Compare domestic housing design across different world climatic zones eg. igloos to dugouts, for their effectiveness in controlling the climate within. Present findings on a chart.
Document the human behaviours that impact on energy consumption in your home/school.
