An investigation into aspects of energy labelling with special reference to washing machines

Abstract

The purpose of this research was to investigate whether the performance of domestic washing machines is adversely affected by reduced levels of energy use. This was felt particularly worthwhile because of the introduction of energy labelling for washing machines in April 1996. Results were determined by conducting tests derived from BS EN 60456. This research also aimed to discover consumer awareness of energy labelling and factors likely to influence the future purchase of washing machines. The results indicate that washing performance may be adversely affected by lower levels of energy consumption and that washing machines with a higher energy consumption achieve a better washing performance. From the survey carried out, it was discovered that the most influential factors when purchasing a washing machine were price, washing performance and brand reliability. Environmental factors such as reduced energy consumption and reduced water consumption only played a minor role in consumers' considerations. However, the research indicates that consumers' decisions may, in the future, be affected by the information displayed on energy labels.
