Study On The Evaluation Of Residential Depreciation Caused By The Infringement Of Daylighting Right

With the development of economy,daylighting has become a main technical index reflecting the quality of people’s daily life.The intensity of light and the range of daylighting have a great impact on our life.In contemporary times,the internal ventilation,daylighting and sunshine of buildings have become one of the topics of increasing concern in the society.With the increase of urban land value and the increase of highrise buildings,these changes lead to more and more problems related to daylighting and sunshine.Therefore,the depreciation of housing market value has also become an important basis to measure the amount of compensation for daylighting infringement.According to the relevant literature,in China’s existing practice,the calculation of house depreciation caused by the influence of daylighting right is not mature enough.On the one hand,there is a lack of relevant specific regulations to specify how to accurately calculate the amount of compensation.On the other hand,the amount of compensation caused by personal factors is often subjective.In the current calculation method,the cost method calculates the increased expenses of the house due to the influence of daylighting,so as to determine the amount of compensation,but this method will calculate part of the amount less;The income obtained in the income method is difficult to measure.Based on the above background,on the basis of scholars’ research and reading a large number of documents,this paper uses the market method to calculate the housing depreciation.In the calculation,taking the daylighting blocked houses in dingxiangyuan community as an example,the selection of comparable examples and the measurement of the weight of relevant factors are determined by the fuzzy comprehensive evaluation method and analytic hierarchy process in machine learning,Then obtain suitable comparable cases and further calculate the depreciation amount of housing value.The results show that :(1)after comparing the market method,income method and cost method,it is feasible to use the improved market method to calculate the house depreciation caused by daylighting right.This method can provide new ideas for the compensation disputes caused by the lack of daylighting right in our country.(2)The fuzzy mathematics method solves the calculation of fuzzy variables.Through the theory of fuzzy mathematics and analytic hierarchy process,the weight of various factors affecting house daylighting is determined.This model analysis can solve the problem of factor correction of comparable cases in the market method.The houses affected by daylighting are adjusted by various factors,It is reasonable that the obtained house price is lower than the normal house price range.
