Abstract
In supporting the prevention of global warming, highly energy efficient cold/hot water-saving equipment has been developed and it has been increasingly introduced in houses. Especially, when it comes to the hot-water supply equipment in Japan, which takes up 30[%] of total domestic energy consumption per household, cold/hot-water saving with single-lever faucets, which very much relies on how individuals use such faucets, is put to the test. Through both an experiment with participants and Actual house actual survey and questionnaire survey on the Web, the study discusses a method for controlling the operation of single-lever kitchen faucets so as to prevent the waste of hot water, a method for using such faucets and the awareness of residents, and from the results acquired from the experiment and survey, this paper proposes a method for using such faucets and the necessity of energy conservation to be considered in product development.
