Presentation of commercial culture and incorporation of corporate culture into commercial space are distinct to each shopping center operator. In addition to product sales and services, commercial space in high-rise buildings provides leisure facilities, dining services, accommodation, wedding and banquet venues, and conference rooms. Commercial space also serves as a key consumer attraction and landmark. This study examined key indicators of commercial space design in high-rise buildings. A literature review and in-depth interviews with experts and practitioners in various fields related to interior design were conducted, and real cases of interior designs for commercial spaces in high-rise buildings were referenced to construct an indicator framework and analyze indicator weights. Investors and operators of well-known shopping centers in Taiwan, international brand extension project operators, and commercial space design vendors were invited for interview to share their experiences and opinions. This study also used the Delphi questionnaire and analytic hierarchy process to determine key factors for commercial space design. According to the results of the questionnaire analysis, the commercial space designers and operators posited that energy conservation was the most crucial factor for the design and management of commercial space, followed by corporate identity system and tender experience. These findings suggest that designers and shopping center operators must prioritize environmental awareness and pay attention to the effectiveness of the corporate identity system. Moreover, rationality of circulation, convenience of facilities, and refined space can contribute to the popularity of commercial space in high-rise buildings and the added value of customers. Use of customer satisfaction to increase customer retention alongside use of information technology can contribute substantially to the development of commercial space in high-rise buildings.
