A questionnaire survey on the consciousness of the residents living in the mid-to-high-rise apartment houses in the commercial district near Kawaguchi station was administered. The sunshine hours at the same apartment houses was also measured by a computer simulation. Results shows that nearly 70% of the answerers in the commercial district demand sunshine more than now. And the priority of the convenience was not related to such residents' demands for the sunshine. Therefore, the standard for the sunshine in commercial districts is necessary. In this survey, 5 sunshine hours were found to be necessary for the residents even in commercial district.
