Making Use of Energy 7 e) How energy from a houses can be restricted e.g. loft insulation, double glazing, cavity wall insulation and draught excluders the cost effectiveness and efficiencies of different methods of reducing energy loss from the home: to compare their effectiveness To use data to compare the economics of domestic insulation technique- including the calculating of payback. The economic and environmental issues surrounding controlling energy loss how data can be obtained and used to investigate the cost of using a variety of energy sources for heating and transport.
