China is in the stage of promoting the renovation of old neighborhoods, which requires the development of fair assessment indicators and reliable tools and methods for assessment work. In this paper, we focus on the livability of outdoor spaces in old neighborhoods, with the goal of establishing an assessment system to analyze livability levels and test whether a virtual scenario tool can replace actual spatial assessments. Based on the previous literature, standard reconstruction documents, and interview results, evaluation elements were formulated, the Delphi method was used to filter and modify the evaluation elements, the analytical hierarchy process was used to establish an assessment system, fuzzy comprehensive evaluation was applied to assess the livability grade of target neighborhoods, and virtual reality was used to implement comparative evaluation experiments between the actual space and the virtual scene. The livability evaluation results for virtual scenes are good; the rate of correct scene matches is 77%. Virtual scenes are highly recognizable, but some model details and real factors are lacking, thus affecting the restoration effect. Considering the technical difficulties of computerized image restoration and the limits of the virtual tool itself, it is considered feasible for virtual scene assessments of livability to replace those in actual space. This approach provides a basis for research using virtual reality technology and a scientific reference for the selection of methods and tools for the assessment of old neighborhoods.
