A field survey of evaluation on environments in the developing housing estate--Results of a four- year survey with questionnaire from 1994 to 1998--

摘要

To evaluate the impact of a developing housing estate, Nissin Kaguyama Estate on the quality of sunlight, air ventilation, and noise, 100 families living in the estate were surveyed annually from 1994 to 1998. The mean relative magnitudes of votes onthe quality of sunlight, air ventilation and noise levels were calculated and analyzed with a dwelling density. Dwelling density was in the range of 9--26 percent. The mean relative magnitudes of votes changed dynamically, and indicated the highest value at a dwelling density of 23 percent, with the exception of those derived from an undeveloped district. The result implies that a dwelling density of 23 percent, or less, may he recommended for future development of housing estates. High-rise apartmenthouses built in 1996 caused most existing families on the estate greater anxiety due to the increasing population and more difficulty in sharing community spirit.
