A Fine-grained Building Height Control Method for Heritage Areas from the Perspective of Visual Integrity

Abstract

This study proposes a refined methodology for controlling building heights in heritage areas. In order to protect the visual integrity of the heritage area, buildings should not obstruct the view from important site points and viewpoints to the periphery. By calculating the building height thresholds that buildings should not obscure the view from each viewpoint, the results of which are weighted and superimposed, and the values are extracted to each building unit as a refined building height control guideline. This study takes the Zhoukoudian area as a case study, applies the refined building height control criterion to the Zhoukoudian Site, and relies on this refined criterion to assess the visual integrity of the Zhoukoudian area, so as to realize the scientific planning and monitoring of the Zhoukoudian area. The refined building height control method can be applied to building height planning and visual landscape protection in large heritage areas.
