Abstract:

The minimization of the property life cycle cost as a criterion for making a decision regarding the economic feasibility of purchasing or building a certain real estate object compared to other objects with functional utility today has become a mandatory requirement of most regulatory and legal acts in Ukraine. At the same time, the practical implementation of this requirement faces the problem of methodical provision of life cycle cost analysis from the standpoint of the uncertainty of these costs in the future and the need to take into account the time value of money. The application of valuation procedures based on cash flow discounting, proposed in this article, can contribute to the solution of this problem. Discounting cash flows will require the classification of life cycle costs not only by content load, but also by the time of their occurrence into initial and future costs, which in turn are divided into once-only, periodic and regular costs. Acceptable units of measurement of discounted cash flows can be net present costs, equivalent annual cost, net savings; savings to investments ratio, internal rate of return, discounted payback period, each of which corresponds to its own model and valuation criterion. To solve the problem of the uncertainty of future costs and to take into account the risk inherent in their forecasting, the methods of analyzing the sensitivity of the results to changes in the market situation are proposed and the justified feasibility of using stochastic discounted cash flows models is justified.

Abstract:

<p><em>Building maintenance is an activity to maintain the reliability of the building so that it remains functional following the Regulation of the Minister of Public Works No. 24 / PRT / M / 2008 concerning Building Maintenance Guidelines; building maintenance includes architectural, structural, and mechanical maintenance. This problem must be considered during building construction to realize the use of structures that fulfil requirements for efficiency, environmental harmony, safety, health, comfort, and convenience. With regular maintenance, the building can achieve its design life with a minor frequency of damage and repair. The cost of building maintenance will increase yearly according to the inflation increase in each region. This study aims to analyze the maintenance costs of the Sports Center building using the LCC (Life Cycle Cost) method with architectural aspects (walls, ceilings, and floors) within the next 20 years. Life cycle costs (LCCs) are costs required by a building over the life of its plan. This approach assesses the total cost of an asset over its life cycle, including initial capital costs, maintenance costs, operating costs, and the residual value of an asset at the end of its life. The study's findings demonstrate how to create a model for predicting maintenance costs. According to this, the Sports Center building must spend IDR </em><em>1.445.082.148,15 on maintenance over the next 20 years. The following includes IDR 280.180.770,42 for ceiling maintenance, IDR 338.260.528,79 for walls, and IDR 826.640.848,94 for flooring.</em><em></em></p>

Abstract:

Kenaf fiber from the kenaf plant is the excellent raw material for industry because of the various diversified products it produces. To develop sustainable kenaf fiber, information is needed on the strengths and weaknesses of kenaf cultivation systems with respect to productivity and environmental impact. Therefore, a comprehensive environmental and economic impact assessment was conducted from cultivating kenaf to kenaf fiber. The environmental impact assessment uses the Life Cycle Assessment (LCA) method and economic calculations from the life cycle of kenaf to kenaf fiber to collectors use the Life Cycle Cost (LCC) method. The calculation of environmental impacts is in accordance with the stages of ISO 14040, using a single score assessment. The LCA results show that the treatment stage is the highest contributor of the three groups of impact categories. The highest to the lowest in the impact category group that was influenced by the treatment stage were resources with a value of 21.4 mPt, human health with a value of 8.76 mPt, and ecosystem quality with a value of 1.91 mPt. The cost identified through the LCC is Rp. 6,088,468,333, NVP and B/Cnet are positive. The results of the sensitivity analysis if there is a reduction in production> 6%, the business is still profitable and can be run.

Abstract:

Abstract With the ever-increasing population, volumes of wastewater treatment are a major concern in our country. The Activated Sludge Process (ASP), Biological Filtration and Oxygenated Reactor (BIOFOR), Upflow Anaerobic Sludge Blanket (UASB), and Moving Bed Bio Reactor (MBBR) are all monetarily investigated in the present study using the Life Cycle Cost Assessment (LCCA) tool. In this study, life cycle costing is done using the present value method, which involves discounting the costs for a 20-year economic life. The costs of treating wastewater per million litres per day (MLD) of wastewater treatment technology are obtained from the literature. Moreover, this study takes into account the capital, annual operation, energy, salvage, and replacement costs to compare the life cycle costs of ASP, UASB, BIOFOR, and MBBR to make the best guess of an economical technology. The LCCA demonstrates that the MBBR has the highest costs of treatment, resulting in the highest Life Cycle Cost (LCC). BIOFOR has the largest energy requirement making LCC the second-highest among the technologies. In India, ASP is one of the most widely used technologies, whose LCC is the third most advanced of the four technologies. Because of its lower energy and operating costs, UASB has the lowest LCC.

Abstract:

In addition to the environmental burden of its construction and demolition activities, the Flemish housing market faces a structural affordability challenge. As one possible answer, this research explores the potential of so-called expandable houses, being built increasingly often. Through specific design choices that enable the disassembly and future reuse of individual components and so align with the idea of a circular economy, expandable houses promise to provide ever-changing homes with a smaller impact on the environment and at a lower cost for clients. In this paper, an expandable house suitable for various housing needs is conceived through a scenario-based research-by-design approach and compared to a reference house for Flanders. Subsequently, for both houses the life cycle costs are calculated and compared. The results of this exploration support the proposition that designing expandable houses can be a catalyst for sustainable, circular housing development and that households could benefit from its social, economic and ecological qualities. It requires, however, a dynamic perspective on evaluating their life-cycle impact.

Abstract:

Black liquor evaporation is generally the most energy intensive unit operation in a pulp and paper manufacturing facility. The black liquor evaporators can represent a third or more of the total mill steam usage, followed by the paper machine and digester. Evaporator steam economy is defined as the unit mass of steam required to evaporate a unit mass of water from black liquor (i.e., lb/lb or kg/kg.) The economy is determined by the number of effects in an evaporator train and the system configuration. Older systems use four to six effects, most of which are the long tube vertical rising film type. Newer systems may be designed with seven or even eight effects using falling film and forced circulation crystallization technology for high product solids. The median age of all North American evaporator systems is 44 years. Roughly 25% of the current North American operating systems are 54 years or older. Older systems require more periodic maintenance and have a higher risk of unplanned downtime. Also, older systems have chronic issues with persistent liquor and vapor leaks, shell wall thinning, corrosion, and plugged tubes. Often these issues worsen to the point of requiring rebuild or replacement. When considering the age, technology, and lower efficiency of older systems, a major rebuild or new system may be warranted. The intent of this paper is to review the current state of black liquor evaporator systems in North America and present a basic method for determining whether a major rebuild or new installation is warranted using total life cycle cost analysis (LCCA).

Abstract:

Reflective cracking is a major and costly problem in many countries. It occurs in the top (overlay) layers above existing cracks in the lower (existing) pavement. This type of cracking can lead to premature deterioration of the pavement structure through the infiltration of moisture and debris. Although extensive research has been directed toward mitigation of the problem, work needs to be done, as it still appears to be a major problem. The problem is related in part to the fact that most of the work being done involves rehabilitation. One of the most common types of pavement rehabilitation is the use of an asphalt overlay. The focus of the present analysis is the economic benefits of reducing and treating reflective cracking before the placement of an asphalt overlay. A methodology for converting crack spacing to roughness is also presented. This information is used to examine how cracking is related to the measured international roughness index values. A model relating the amount of cracking to the loss of serviceability or a reduction in service life is presented. That model indicates that a reduction of transverse crack spacing from 5 to 20 m should result in a 5-year extension of service life, with a cost savings of $25,000 (2002 U.S. dollars) per two-lane kilometer. Measurement and treatment of cracking can also yield significant benefits. Benefit–cost ratios from the measurement of cracking can range from about 5 to 50, while proper and timely crack treatment (routing and sealing) can result in an extension of pavement life by 2 years and cost savings of $7,000 per lane kilometer.

Abstract:

During the project: Electric Hybrid Proton Exchange Membrane (PEM) Fuel Cell Transit Buses in China, the authors set up a model to calculate the life cycle cost of fuel cell bus (FCB). The model includes acquisition cost, fuel consumption cost and maintenance cost. In addition, the authors also take the government subsidies into account. After calculating, we see the cost of fuel cell is the most sensitive part of FCB life cycle cost. Using the model, we compared different bus life cycle costs. The result shows that FCB life cycle cost is 5 times more than the current diesel bus.

Abstract:

Energy consumption and pollutant emissions from buildings have caused serious impacts on the environment. Currently, research on building environmental costs is quite insufficient. Based on life cycle inventory of building materials, fossil fuel and electricity power, a calculating model for environmental costs during different stages is presented. A single-objective optimization model is generated by converting environmental impact into environmental cost, with the same unit with direct cost. Two residential buildings, one located in Beijing and another in Xiamen, China, are taken as the case studies and analyzed to test the proposed model. Moreover, data uncertainty and sensitivity analysis of key parameters, including the discount rate and the unit virtual abatement costs of pollutants, are also conducted. The analysis results show that the environmental cost accounts for about 16% of direct cost. The environmental degradation cost accounts for about 70% of the total environmental cost. According to the probabilistic uncertainty analysis results, the coefficient of variation of material production stage is the largest. The sensitivity analysis results indicate that the unit virtual abatement cost of CO2 has the largest influence on the final environmental cost.

Abstract:

With limited funding and a desire to reduce environmental impact, there is a lot of pressure on road Authorities to develop decision making policy to manage better, build and maintain the road network sustainability. One of the solutions is to use various life cycle analyses. Numerous tools are available for different analyses, but they usually evaluate the construction from one perspective (economical, environmental, or social). Therefore, it was decided to develop a tool, which combines economic (Life Cycle Cost Analysis) and environmental (Life Cycle Assessment) analyses. The given study presents the methodology of the self-developed calculation program, which compare full-depth road constructions. Paper also shows shortcomings when calculation does not include all life cycle processes. In this study, five different road pavement constructions and reconstruction plans were compared. The difference between these pavements was in the layer thickness, recycled asphalt content in asphalt layers and the use of cement or fly ash in the road base layers. The results showed that the full depth reclamation technology in comparison to the full-depth removal and replacement reduce emissions by 60% and costs by 50%.

Abstract:

This paper aims to present a method for comparing decision options for the ashore marine engine room. Based on the life cycle cost system, the life cycle stages are divided into design, acquisition, installation, operation, maintenance, and scrapping. A model of the life cycle cost of ashore marine engine room considering the time value of money was developed, and a calculation method for sensitivity analysis was developed. Regarding the actual case, the life cycle cost of the two options was estimated, the sensitivity of the cost of the two options was analyzed, and control recommendations were made. The results show that Option 2, with the highest initial investment, is the optimal solution, attributed to using an advanced two-stroke diesel engine with reduced operation and maintenance costs. This will be useful for reference by maritime academies.

Abstract:

Abstract Most innovative and eco-friendly project alternatives are rejected due to higher initial costs. This problem arises due to the general cost analysis that considers only the initial costs. It can be solved using Life Cycle Cost Analysis (LCCA) approach because LCCA helps the decision makers to select the project alternative with more economic benefits by considering the costs incurred in it throughout the life cycle. In this paper, the life cycle cost analysis of the rooftop garden was carried out and compared with the conventional roof using openLCA software. The rooftop garden includes many environmental benefits such as the reduction of the urban heat island effect, reduction of noise pollution, improvement in quality of air, management of surface runoff and conservation of biodiversity. Still, the use of rooftop gardens is not common in the projects due to their higher initial costs. Thus, LCCA was carried out to evaluate its economic feasibility. A model was developed using openLCA software to carry out the analysis. The costs considered in the analysis include the initial costs, maintenance costs, renovation costs and energy costs. The cost data were collected for extensive rooftop gardens laid in commercial buildings in and around Chennai city. The results indicate that the initial cost of the rooftop garden was 5.2 times higher than that of the conventional roof but due to the prolonged life period and the energy savings of the rooftop garden, the life cycle cost was 5.25% lower than that of the conventional roof.

Abstract:

Abstract The aim of this study is to perform a life cycle cost analysis (LCC), where the economic cost of extending service life by the impregnation of bridge edge beams is compared to the reparation of an edge beam. Previous economic analyses on bridge edge beams had shown that there was no clear economic benefit in impregnating the edge beams. However, results from this study pointed out that in most cases there is a clear economic benefit to impregnate the bridge edge beams even if it has to be repeated every 15 years.
