Recognise good and bad conductors.
Recognise that curtains reduce energy loss through windows.
Recognise that many insulation materials contain air.
Apply the fact that air is a very good insulator to its use in keeping homes warm:
- fibreglass or mineral wool is used as loft insulation;
- double glazing in windows;
- cavity-wall insulation foam;
- reflective foil in or on walls;
- draught-proofing.
Interpret data and calculate cost savings of different energy saving strategies:
- payback time.
- State and use the equation:
efficiency = useful energy output
total energy input
Explain in the context of the home the concepts of conduction, convection and radiation (absorption and emission) in terms of:
- the design features of the home;
- the design and use of everyday appliances in the home;
- energy saving strategies.
State and use the equation:
efficiency = useful energy output
total energy input
