GUIDELINES FOR PLANNING INNER-PLAZA ATRIUMS BASED ON USERS' ASSESSMENT : Multiple regression analysis of satisfaction and ease of access from staying-user questionnaire survey data

Satisfaction and ease of access were proposed as primary indices of the users' assessment of inner-plaza atriums through factor analysis of twenty-two sample questionnaire survey data involving 1,503 staying users. Their explanatory variables were then identified through multiple regression analysis, which allowed the development of a set of calculation charts for the easy evaluation of atrium proposals. As much as 91.8 to 95.6% of variance was explained with factors of access, openness, atrium scale, events and spatial capacity for staying along with exterior open space, landscaping, and link-to-outside factors in predicting satisfaction and an amenity or centrality factor in predicting ease of access.
