Fit an insulating jacket around the hot water geezer. This will save about 150 kg Co2 per year. If floors and doors have gaps around them, it accounts for 11% of heat loss in a home that is not insulated. If you have an air conditioner in your home, turn it down by 1°C and save 300 kg Co2 per year. Have a shower instead of a bath and use two thirds less energy and save on water. If you can afford this, upgrade to an energy saving recommended fridge freezer and save 190 kg Carbon dioxide per year. Windows and doors could also be draught proofed to save 140 kg Co2 per year. Walls leak a lot of heat. Therefore have them insulated and save approximately 1 ton of Co2 per year. A fifth of heat is lost through windows. Windows could be double glazed to save heat. If you decide to do the laundry, wash clothes at a lower temperature and use one third less electricity. When the TV and other appliances are not in use, turn them off and save on a substantial amount of energy.

  • This is little more than a description without a context - is heating the major issue for the avergae Cape Town House.

    How would you insulate the walls?

    Have you thought about the costs - e.g. double glazing in SA is really expensive.

    This reflects too closely on the reference you have provided did you consult more widely?
