Water use with energy-efficient faucets (engelsk)
Abstract [en]

This study investigated the short and long term impacts of domestic hot and cold water use and associated energy use when replacing conventional faucets in 100 apartments with energy efficient faucets labeled with energy class A-B according to the Swedish energy labeling system. The study included a behavioural study to increase the understanding of the users’ perception of the faucets and to investigate the underlying reasons for acceptance of the installed products.

 

The results showed a reduction in domestic hot water use and energy use for domestic hot water of 28 %. No reduction of cold water use could be identified although changes in occupancy of the apartments might have contributed to this result. The savings in hot water use did not diminish over the measurement period.

 

The acceptance of the energy efficient faucets did not increase over time, which was likely due to the lack of feedback on the assumption that the faucets provided the indicated savings. It was also indicated that the perception of the faucets differed between contexts in the home. The acceptance was also found to be linked to factors that could not be isolated from the faucet and its function.
