Abstract

This study aimed to determine the effects of industrial architecture components on improving the architectural quality of mid-rise residential buildings in Kerman and to identify the components exerting the strongest effects on architectural quality. This mixed-methods study employed qualitative and quantitative approaches and was applied-developmental in purpose and descriptive-survey in data collection. In the qualitative phase, the Delphi method was conducted with 50 architecture professors to identify the components and indicators of industrial architecture and architectural quality. The quantitative population comprised 420 licensed professionals affiliated with the Kerman Construction Engineering Organization; after questionnaire distribution and data screening, 328 valid cases were included in the analyses. The instruments were a researcher-developed Industrial Architecture Questionnaire containing 53 items across nine components and an Architectural Quality Questionnaire comprising 55 items across ten components. Face and content validity were confirmed by 15 architecture professors, while construct validity was examined using exploratory factor analysis. Data were analyzed using SPSS version 23 and AMOS version 22 through Pearson correlation analysis and structural equation modeling with maximum likelihood estimation. Pearson correlations indicated significant positive relationships between all industrial architecture components and architectural quality (r=0.14–0.39, P<0.05). The structural model demonstrated acceptable fit (χ²/df=2.74, GFI=0.91, CFI=0.92, IFI=0.921, NFI=0.901, TLI=0.902, RMSEA=0.057). Significant positive effects on architectural quality were found for computer-assisted optimization of design components and spaces (β=0.71, t=7.47, P<0.001), construction-oriented design (β=0.31, t=5.40, P<0.001), controlled factory production (β=0.29, t=3.94, P<0.001), disassembly and reassembly capability of the construction process (β=0.31, t=5.16, P<0.001), flexibility in planning processes and semi-finished component production (β=0.21, t=3.16, P=0.004), and environmental compatibility (β=0.27, t=3.54, P<0.001). In contrast, computer data-based ideation, rationalistic component and spatial design, and standardized semi-finished components had no significant direct effects (P>0.05). Architectural quality in mid-rise residential buildings appears to depend primarily on the integration of design and construction, computer-assisted optimization, flexible production and assembly processes, controlled factory production, and environmental compatibility rather than on standardization or computer-based ideation alone. Accordingly, systematic application of these industrial architecture components may provide an effective framework for improving the architectural quality of mid-rise housing in Kerman.
