Occupants’ Perceptions of Amenity and Efficiency for Verification of Spatial Design Adequacy

Abstract

The best spatial design condition to satisfy the occupancy needs of amenity and efficiency is determined through analyzing the spatial design adequacy (SDA). In this study, the relationship between the space design elements and space on future occupants’ perception are analyzed. The thirty-three participants reported their self-evaluated SDA that describes the quality of eight alternative housing living rooms with different spatial factors. The occupants were guided through the perception processing elaboration in order for them to evaluate the actual perception in the real space. The findings demonstrated that the spatial size (e.g., width, depth, and height) is significantly correlated with the overall satisfaction of amenity. It is also found that the spatial shape (e.g., the width-to-depth ratio, the height-to-area ratio, and room shape) may significantly influence the overall satisfaction of efficiency. The findings also demonstrate that the causal relationship between the spatial factors and space is clearly present in the occupants’ perception, reflecting the time-sequential characteristics of the actual experience divided into amenity and efficiency. This result indicates that the correlation between the spatial factors and space of SDA under the occupants’ perception processing elaboration can be a useful guide to predict the occupancy satisfaction of amenity and efficiency in real spaces.

The Effect of Interior Design Elements and Lighting Layouts on Prospective Occupants’ Perceptions of Amenity and Efficiency in Living Rooms

“…Results of the study indicated that the correlation between spatial factors (size and shape) and SDA based on the elaboration of occupants' perception processing can be a useful guide to determining spatial size and shape and predicting occupants' satisfaction regarding amenity and efficiency in real spaces [4].…”

“…In the first step, findings of a previous study demonstrated that the causal relationship between the spatial size and shape factors (e.g., spatial size, shape, and configuration of spatial elements and space) was clearly presented in occupants' perceptions, which reflected the time-sequential characteristics of an actual experience according to amenity and efficiency [4].…”

“…Spatial design adequacy (SDA) means the spatial design qualities that can satisfactorily fulfill occupants' goal in an actual space [4]. Amenity, or comfort, is subjective satisfaction; occupants 2 of 30 feel agreeable in spatial conditions that align with their lifestyles and social, cultural, and personal background, and their own experiences [4].…”

“…Spatial design adequacy (SDA) means the spatial design qualities that can satisfactorily fulfill occupants' goal in an actual space [4]. Amenity, or comfort, is subjective satisfaction; occupants 2 of 30 feel agreeable in spatial conditions that align with their lifestyles and social, cultural, and personal background, and their own experiences [4]. Efficiency, or convenience, refers to the subjective satisfaction of occupants when they are not stressed because of spatial conditions that agree with certain behaviors and activities [5][6][7][8].…”

“…(2) the actuality was not fully investigated in actual space [14]; and (3) redundancies existed between amenity and efficiency [4].…”
