The purpose of this study is to clarify the changes of water usage and consciousness of water-saving in Fukuoka-city by comparing the past investigation results in 1989 with those in 1999 passed 20 years from the big water shortage, and to collect the basic data for the planning of effective water usage in houses. In this paper, we clarified the factors of distinction between the results of investigation in 1989 and those in 1999 for detached houses and apartment houses respectively. And we analyzed quantitatively the changes of the factors affecting the volume of water consumption and so on.

Passive utilization of natural energy is one of the most reasonable way to improve the urban thermal environment in the warm season. The sea-land breeze is an appropriate energy source for this purpose. Statistical method to extract and express the sea-land breeze component from the wind data and the relation between that and the solar radiation data are described in this paper. The AMeDAS and the SDP data, from 1980 to 1984, in 12 cities which are scattered in the whole country are used. The analysis period, which means the warm season, is fixed on condition that the 7-day moving average of daily mean air temperature is above 20℃. The sea-land breeze axis is decided from the wind rose in the analysis period. The sea-land breeze component means the wind vector component of this axis. Sea breeze hours and land breeze hours are fixed by the average sea-land breeze component at each time. The characteristics of the wind direction and speed in the sea and the land breeze hours correspond to the general nature of the sea-land breeze. The sea-land breeze intensity is defined as the difference between the average sea-land breeze component in the sea breeze hours and that in the land breeze hours. The sea-land breeze stability is defined as the ratio of the sea-land breeze intensity to the sum of the average scalar speed in these hours. The relation between the solar radiation and the sea-land breeze intensity or the sea-land breeze stability is examined.
