Description

Under the background of urban renewal, the research and renovation of existing residential historical and cultural districts in China mainly focus on the overall protection of historical features, the inheritance of architectural symbols and street patterns, and the improvement of functions. At present, the research on the morphological factors and energy consumption of districts and buildings in China is mainly applied to the early stage of urban design for new projects. However, it can no longer meet the current requirement of urban development, which has shifted from "large - scale demolition and construction" to "retention, renovation and demolition" for optimizing the existing stock.Taking the historical district of HeHuaTang in Nanjing as an example, typical layout cases were extracted. Parametric modeling was conducted on the Rhino platform. Three different renovation work premises and regulations were set up in the study: 1）all buildings can be retained or demolished; 2）cultural relics protection buildings are retained, and other buildings can be freely chosen to be retained or demolished; 3）cultural relics protection buildings are retained, dangerous buildings are demolished, and other buildings can be freely chosen to be retained or demolished. Based on the typology theory and the characteristics of residential historical and cultural districts, Spearman correlation analysis was conducted on energy consumption and architectural morphological parameters. The Grasshopper plugin combined with the Energyplus platform was used to perform performance simulation on the model. The EUI of the district was calculated, the Pareto optimal solution was obtained, and then renovation schemes aiming for low energy consumption under different control conditions were generated. The research results provide suggestions and guidance for the design and renovation of residential historical and cultural districts in the context of urban renewal.
