Embodiment Construction

[0099] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0100] Calculation of comprehensive evaluation index weight:

[0101] The project invited five experts to score the weight of a building index, and then used the traditional AHP and the improved AHP to calculate their respective weight vectors and compare them. In the improved AHP, set θ’=0.9, that is to choose a slower convergence rate and a smaller deviation, set And the weights among experts are equal, that is, both are 0.2. The five experts scored in the order of human health, energy efficiency, resource efficiency, environmental responsibility, and affordability as follows:

Abstract

The invention discloses a green building intelligent energy-saving assessment management system based on a Web geographic information system (GIS) and belongs to the technical field of assessment of green buildings. The green building intelligent energy-saving assessment management system based on the Web GIS is characterized in that: buildings with different characteristics are classified by using a clustering method; primary indexes of all classes of items are determined by using a principal component analysis method; corresponding secondary indexes and tertiary indexes are established through layered breakdown by using a work breakdown structure (WBS) method; the primary index which corresponds to each class is stored, and an index database is established; credibility and compatibility are improved on the basis of the conventional analytic hierarchy process, and a weight optimization model is established; a calculation model of an energy-saving performance comprehensive index is established by using a variable fuzzy evaluation method; the weight optimization model is introduced for determination of building index systems and weights under different levels; and a set of internet-based green building assessment system is developed on a Web GIS platform. The invention has the advantages that: the original information of each expert is reserved to the largest extent; the green building intelligent energy-saving assessment management system based on the Web GIS is convenient for operation and better in universality and practicability; information is shared; and the importance of the past experience on project management is emphasized.

Description

technical field [0001] The invention belongs to the technical field of green building evaluation, and relates to a green building energy-saving evaluation method, in particular to a WebGIS-based green building intelligent energy-saving evaluation management system. Background technique [0002] In the past 20 years, the scale of my country's buildings has expanded rapidly, but correspondingly, the problem of energy consumption in my country's buildings has become increasingly prominent. At present, more than 80% of the newly-built houses in my country are high-energy-consuming buildings; among the existing houses, more than 95% are high-energy-consuming buildings. more than double. Regardless of the overall international economic climate or the general trend of China's macro economy, China's resource and energy problems have become increasingly severe, and energy conservation is imperative. Therefore, my country is facing a huge bottleneck of resource constraints and the pre...
