Chappy Screenshots

Main screen

The main screen of the primary school interface is in 3D creating a more exciting and interactive environment for younger users. The calculations function in the same way as the high school interface. However the details are fewer than in the high school side, and you can jump between stages, for example choosing construction details from inside and outside of the house.

The program screen is broken up into three sections:

The 3D house environment

The 3D house environment allows the user to move from room to room, allowing you to make choices about the construction materials used to build the house, the househouse appliances in the hoiuse and their use. Along with other choices as the source of electricity used in the house.

The fitout and appliance "Discarded items box"

In the middle of the screen there is the "Discarded Items Box". This contains the appliances and fitout items, such as a pool which have not been chosen for the house. For example if you mouse over the lawn mower and choose "none" an icon for the lawnmower will appear in this box. You can mouse over it here if you wish to put it back into the scene.

The reporting and information section

The reporting and information section contains a number of choices for displaying the information.

• The results are shown by a blue indicator bar which is updated as soon as a change is made. A white arrow below the bar indicates the NSW Average for each impact.
• The attribute or impact being measured, for example Greenhouse Gas Emissions (GGE), Energy use in Giga Joules (GJ) or Water consumption (tonnes) can be selected from the "Attribute" menu on the left hand side below the indicator bar.
• The units of the indicator bar can be selected on the right hand side below the indicator bar. For example results are related to the number of trees that need to be planted to sequester the carbon dioxide, Similarly, the resource energy is related to the equivalent energy content of petrol.
• Help, tips and facts are located on the right hand side of the screen.

Report screen

More detailed results are available from the report screen. This displays an "Energy Bill" showing the cost of the household energy supply. The amount of greenhouse gas saved by using more efficient technologies is also shown, along with the cost of the greenhouse gas savings The default values for the different energy technologies can be changed to keep up with improvements in the cost of old and newer energy technologies.

The detailed histogram of each stage is also available from the stage graph button.

Main screen

On the right hand side are buttons to select the stage you wish to view. Individual items are listed on the left of the grid, with details about the items to the right.

Results

The high school results contain detailed histograms of the various impacts, such as resource energy or greenhouse gas emissions. Two bars are graphed, the average NSW impact and the example set up by the user.

Item details

In the high school interface you can look at the details of each item. The details contain the equations which calculate the material consumption, and also show the impacts of the item.

Bill of materials

A complete bill of materials can also be viewed, listing all the material consumed for each particular item.

Materials data

Following the theme of complete transparancey, CHAPPY also shows the resource energy and emissions associated with the manufacture of each of the materials used.
