There has long been a lack of understanding of the costs and benefits of energy-efficient renovation of existing buildings, which discourages the participation of stakeholders. This paper studied the energy-saving renovation of existing buildings, analyzed the incremental cost and incremental benefit based on the whole life cycle, and constructed the economic evaluation model of energy-saving renovation of existing buildings to provide a scientific theoretical basis for the economic evaluation of the energy-saving renovation of existing buildings and provide references for the decision-making of stakeholders, and promote the energy-saving renovation of buildings from an economic point of view.

Economic Evaluation Model

With the shortening of product life cycle, and the constant increasing of End-of-life Electromechanical Products, the processing of waste products appears especially important and urgent. This paper, based on an existing recycle model, has established an economic evaluation model of end-of-life electromechanical products. Based on the collection of a large amount of data and tests, the research and evaluation of the engine has proved it is suitability for remanufacturing.

The Impact

In the established model of economic evaluation, it considers the impact of construction conserves energy elements of existing buildings and adopts payback period of dynamic energy as the evaluation criteria. It proves that the model has practical value by using DeST-h software to simulate building energy consumption of existing buildings and retrofitting buildings.

Hierarchy Process

To solve technical and economic evaluation in the design stage of energy-saving buildings, rank the rationality and economic performance of energy-saving technologies under limited condition and provide basis for the amendment and optimization of energy-saving building schemes, technical and economic evaluation model which is according to matrix evaluation method and analytic hierarchy process is put forward and is used in an project to verify its feasibility. This model chooses energy saving rate, renewable energy contribution rate, add capital ratio and payback period of investment as indexes to describe, explain and evaluate the energy-saving technologies. And this model which can truly realize energy saving in the initial design is well adapted.

Purpose: This manuscript explores the link between Spare Parts Management and Total Costs of Ownership or Life Cycle Costs (LCC).Design/methodology/approach: First, this work enumerates the different managerial decisions instances in spare parts management that are present during the life cycle of a physical asset. Second, we analyse how those decision instances could affect the TCO of a physical asset (from the economic point of view). Finally, we propose a conceptual framework for incorporating the spare parts management into a TCO model.Findings: The recent literature lacks discussions on the integration of spare parts management with the Total Costs of Ownership (TCO). Based in an extensive literature revision we can declare that the computation of costs related to spare parts management has been neglected by TCO models.Originality/value: The contribution of this paper is twofold. First, a literature review and identification of a series of spare parts management decision instances and its relationship with TCOs is presented in this paper. Second, a conceptual framework is suggested for linking those decisions instances to a total cost of ownership perspective. Some research questions and future research challenges are presented at the end of this work.

We have viewed a business in the south of the Great Plain Region from an economic point of view in 2004-2005. The main activity there is pear growing and storage. Four varieties of different time of ripening and storing are grown there. We have measured all the relevant activities, worked out a local normative and prepared a detailed technology. The economic evaluation was based on this data. Activities, like disinfection, pre-storage disinfection and selection, in-storing and out-storing, classification after storage, packaging, as well as loading trucks, were monitored by variety. Storage loss was determined and widely varied according to varieties, length of storage and time of out-storing. Different varieties resulted in different quality classes after storage. Price depended on the quality classes. Economic evaluation was carried out when all the relevant costs and revenues were known. Fixed and variable costs of storage were determined, break-even point was calculate and the market position of the product was evaluated.

The purpose of this study is to analyze the production of copper nanoparticles (Cu NPs) on an industrial scale in an engineering perspective and economic evaluation perspective. Energy is needed because of various energy related applications. Evaluation of Cu nanoparticle production in an engineering perspective is carried out from the selection of processes that are adapted to industrial scale, calculation of mass balance, to the adjustment of commercially available equipment. Evaluation of production from an economic point of view is done by calculating economic parameters: Gross Profit Margin, Internal Return Rate, Payback Period, Cumulative Net Present Value, Profitability Index, and Break Even Point. Briefly from the production process, we use Copper acetate hydrate (CuAc2.2H2O) (as a source of Cu), Tween 80 (polyoxyethylene-(80)-sorbitan monooleate) and ethylene glycol (as a reducing agent). The engineering viewpoint shows this process is capable of producing Cu nanoparticles which can be used as conductive nanoionic. Economic evaluation determines the process is beneficial, discussing with positive values ​​all economic parameters. However, for some variations this process is not profitable, so economic evaluation is needed.
