Building continuous design method based on full life cycle cost estimation

Abstract

The invention discloses a sustainable design method for architecture based on life-cycle cost (LCC) valuation, which comprises three stages of program design, preliminary design and construction documents design. Each step is composed of the following steps: 1) inputting design elements; 2) carrying out the program design, program evaluation and program selection based on a LCC sustainable design package; 3) outputting the design results. The sustainable design method for architecture based on life-cycle cost(LCC) valuation of the invention integrates LCC in the building design, forms the sustainable design package based on LCC, and establishes the sustainable design framework based on LCC, thus improves the sustainability of the building (design). Additionally, the invention improves the quota design mode, which enables the building design program to realize the lowest LCC under the condition of satisfying the quota constraint.

Description

technical field [0001] The invention relates to the field of engineering cost, in particular to a sustainable design method for buildings based on full life cycle cost evaluation. Background technique [0002] At present, many studies have paid attention to the importance of Life Cycle Costing (LCC) in achieving sustainable development, and discussed how to improve the sustainability of buildings through the implementation of life cycle cost analysis, mainly focusing on the following aspects: Three aspects: the role of LCC in submitting architectural design proposals for sustainability; constructing a full life cycle cost model, that is, how to define the composition of the full life cycle cost during the design process, and accurately predict the full life cycle cost of the design proposal, and judge The uncertainty of the cost; the application of LCC in the evaluation and selection of design schemes; the measures to strengthen the application of LCC in design and improve s...

Problems solved by technology

[0003] The above studies on the application of LCC in architectural sustainable design have the following problems: sustainable design is only a design method or concept, and has not yet formed a mature design model; Application in sustainable design; the lack of organic integration between sustainable design and LCC, resulting in sustainable design schemes may be rejected due to high initial investment, sustainable design schemes lack economic efficiency, the gains outweigh the losses, or lack of optimization schemes under financial constraints effective method

On the other hand, the quota design inhibits the further improvement of the sustainability of the design scheme. During the design process, too much attention may be paid to how to realize the basic functions of the project under the constraints of the quota, and the reduction of future operation / maintenance costs may be ignored, and Under the constraints of quotas, how to efficiently use available resources and improve the sustainability of buildings lacks effective methods
