Integration Factors of Design Participants in Performance-Based Building Design of Commercial Property

Design practice has shifted towards a performance approach that is based on an awareness of sustainability goals. Achieving this goal requires the integration of all participants through communication, collaboration, and knowledge-sharing (CCKs), specifically at the design stage. The participants are from different stages of the project which are design management (DM), project management (PM), and facility/property management (FM). The current research has not been able to clearly describe the practice in achieving design performance, especially involving the main three stakeholders (DM, PM, and FM). Thus, this study aims to fill the research gap by focusing on the influence of factors CCKs on the design performance of the commercial property, especially retail property. This will form a design, construction, and operational integration model to achieve the performance of retail properties in forming an optimal space. This study uses a method of quantitative study using a questionnaire survey. It was collected from 111 practitioners of the project participants (DM, PM, FM) in retail property development in Indonesia. There are different results in the correlation that the higher the factor value, the lower the space value performance. This correlation occurs in collaboration for PM, communication for DM, and knowledge-sharing for FM. This interesting finding can be explained empirically according to the preferences of each participant. This study contributes to knowledge about the influence of CCKs, which focus on the design of performance-based retail buildings to get the highest space value.
