ABSTRACT

The conservation and renovation of Beijing siheyuan courtyard houses require a balanced consideration of the preservation of intrinsic heritage values and the effectiveness of contemporary adaptation. Existing evaluation approaches are often limited by single dimensional frameworks and therefore struggle to provide comprehensive and scientific assessments. This study proposes a comprehensive evaluation model that examines the coupling relationship between the intrinsic value base of Beijing siheyuan and the effectiveness of renovation interventions. Four principal dimensions of intrinsic value are identified, including architectural character and artistic features, architectural value, cultural continuity, and historical integrity. These dimensions are used to establish a graded evaluation of intrinsic values and to determine objective weights. At the same time, four dimensions of renovation effectiveness are incorporated, including functional adaptability, cultural continuity, techno economic performance, and ecological sustainability, forming a quantitative evaluation framework based on key indicators. Factor analysis is employed to determine the weighting of intrinsic value dimensions, while the extreme value method is used for indicator normalization. A value level adjustment coefficient is introduced to construct a coupling calculation model that integrates intrinsic value and renovation effectiveness. Empirical analysis based on typical siheyuan renovation projects in Beijing demonstrates the operability and reliability of the model. The results indicate that the model enables more precise and differentiated evaluation of renovation outcomes, providing a quantitative tool and decision making reference for hierarchical conservation and targeted renovation of Beijing siheyuan. The framework also offers methodological insights for the evaluation of conservation and adaptive reuse in historic architecture.
