Domestic Appliances End-use Efficiencies: The Case Of Eleven Suburbs In Greater Johannesburg

M. V. Shuma-Iwisi & G. J. Gibbon
Results from an appliance survey indicate appliance saturation and penetration levels suggesting a sizeable domestic appliance load. The largest contribution to the domestic load is mainly from universal appliances. Measurement results of appliance power consumption reveal a wide range of consumption levels in appliances with the same functionality. This was observed in all operational modes indicating lower end-use efficiency in most appliances. Appliances that meet the 1 watt standby minimum power consumption are an exception. Domestic demand tariff is an option to cover the cost to the supplier and to reduce significant demand due to apparent power components. The impact of energy inefficient appliances to the consumer and the utility companies is unknown, indicating a need for consumer education and consumer awareness programs. Keywords: end-use efficiency, appliance saturation levels, appliance penetration levels, universal appliances, power consumption levels, efficiency standards, consumer awareness.
