Existing residential building performance hierarchical evaluation method

Abstract

The invention discloses an existing residential building performance hierarchical evaluation method. The method comprises the following basic steps: (1) constructing a hierarchical structure model; (2) constructing a judgment matrix; (3) determining weight coefficients of the index elements; (4) calculating a conclusion in a hierarchical manner; and (5) analyzing the conclusion, and giving existing residence performance evaluation suggestions. The connotation of existing residential building performance hierarchical evaluation is based on the AHP analytic hierarchy process by utilizing the principle of system theory, the evaluation result directly reflects the value degree and level of the existing residential building performance, and a scientific and accurate existing building evaluationmethod is provided for urban decision departments and urban update and construction institutions.

Description

technical field [0001] The invention relates to the field of performance evaluation of residential buildings, in particular to a hierarchical evaluation method for the performance of existing residential buildings. Background technique [0002] my country's urban renewal construction has entered a stage of accelerated development. Along with the renewal and transformation of the old city, the existing residences are experiencing physical aging and social decline with the difference in construction age, and most of the existing residences are concentrated in the city center. The land value is extremely high, which cannot meet the urban development and the growing material and spiritual needs of residents to a certain extent. However, the structures of these residences are generally intact. Proper renovation can extend their economic life, reduce construction scale, and recycle construction resources, which is more conducive to environmental protection. Low, lack of necessary ...

Problems solved by technology

[0002] my country's urban renewal construction has entered a stage of accelerated development. Along with the renewal and transformation of the old city, the existing residences are experiencing physical aging and social decline with the difference in construction age, and most of the existing residences are concentrated in the city center. The land value is extremely high, which cannot meet the growing material and spiritual needs of urban development and residents to a certain extent

However, the structures of these residences are generally intact. Proper renovation can extend their economic life, reduce construction scale, and recycle construction resources, which is more conducive to environmental protection. Low, lack of necessary maintenance during use, prominent performance problems, urgently need to improve functions and facilities through renovation

[0003] However, in the renovation process of existing residences, from the individual level, the repair standards and guiding principles are not clear, and there is a lack of evaluation methods and guiding principles to guide practical application. As far as development companies are concerned, there is a lack of a scientific evaluation system for the goals and technical measures of residential renovation, as well as the performance evaluation of existing houses. Indexes and methods, formulate the standard "Technical Standards for Residential Performance Evaluation" GB50362, which divides residential performance into five aspects: applicable performance, environmental performance, economic performance, safety performance and durability performance. There is a certain lack of performance evaluation

Relevant qualitative and quantitative indicators need to be scientifically researched and tested, especially for the assessment of the human settlements of existing residential buildings. Protection, Identification and Assessment Measures
