Abstract

The purpose of this study is to identify the necessity of improving external environmental quality in the regeneration of old residential complexes and to analyze the influence of outdoor spatial planning elements on thermal comfort. The Chegongzhuang district in Xicheng, Beijing, was selected as the case study area, and its land use, building and population density, transportation systems, greening patterns, public spaces, and facility distribution were examined. Three typical block layouts—linear, enclosed, and mixed—were analyzed in terms of spatial organization, internal circulation, public zones, and greenery. Using ENVI-met simulations, the impacts of pavement materials and greening strategies on outdoor thermal comfort were quantitatively evaluated. The results show that high-albedo pavement can reduce air temperature by about 1°C but increases radiant heat load in unshaded areas. In contrast, increasing the green coverage ratio from 12% to 33% lowered PET by up to 4°C, and taller trees improved thermal comfort by as much as 10°C. Mixed tree–shrub planting was more effective than single-species arrangements. Overall, greening strategies proved more effective than pavement modifications in enhancing outdoor thermal comfort, emphasizing the need for integrated consideration of vegetation design and material selection in the sustainable regeneration of old residential complexes.
