The present thesis reports of the activities of a Team project“ Assessment Project for Criteria for Human Life Quality”, established by several members of the Department of Life Environmental Sciences. Preliminary research was mainly conducted in areas of consumer products use, housing facilities, as well as the cultivation of public opinion and attitudes towards low energy life. The high accumulation of systems and functions, the rational and rigid differentiations of tasks and areas, typical of city life, aggravate the alienation of the individual and accelerate the consumption rate of material and energy resource. Further research is necessary, therefore, to relocate the areas in which the needs for privacy and property can be reformulated to embrace a more organic and cyclic concept of life.
