Abstract:Vernacular dwellings in Guanzhong are the product of time and place,with typical spatial system,simple structural form and rich green experience. However,in the process of modernization,excessive reliance on mechanical equipment such as air conditioning leads to the separation of the construction system of vernacular folk houses from the quality of indoor environment. Therefore,taking overall improvement as the goal,the residential renewal of Nanbaozhai Village as the research object,separately form of promotion strategy from the space layout and structure,after integrating the improvement mode of indoor environment from the quality of indoor natural lighting and indoor thermal comfort,the integrated linkage idea is adopted to condense the overall improvement path of indoor environment and apply it to the renewal design of typical preserved residential houses. Combined with quantitative simulation software analysis to further verify the feasibility of the overall upgrade path,in order to provide visual reference value for the overall update design of vernacular dwellings in Guanzhong.
