This study provides a mathematical model that delivers fundamental data for developing a pricing strategy for fuel cell electric vehicles (FCEVs). A mathematical model that transforms the life-cycle cost of a hydrogen vehicle into the corresponding gasoline vehicle is designed using cost-benefit analysis and life-cycle analysis. The FCEV obtains economic advantages when its life-cycle cost is l...
Design decisions are increasingly required to take full account of life-cycle-cost to facilitate specification choice for different building and engineering components. To this end an integrated framework for life-cycle analysis through identification of contributory elements and sub-elements allows analysis via an appropriate tool. The framework presented discusses the opportunity for the util...
Abstract This study analyses, by means of lifespan cost and assessment, the production binary concrete admixtures compound artificial pozzolan demolition waste. Ten formulations were developed, differentiating them in terms mixtures, binder aggregate content, order to verify their potential use columns. The replacements 25% Portland cement for fly ash rice husk ash, 15% 30% natural coarse aggre...
The environmental performance of existing buildings can have a major role in achieving significant reductions CO2 emissions: In the UK, around 75% 2050's housing stock has already been built. While building improvement efforts mostly focus on operational performance, impact is result processes that occur throughout their life cycle. To achieve emission an economically viable way, this study use...
Ballast as a part of the railway system plays an important role in the operation of the railways and also has a great impact on repair and maintenance activities. Hence most of the repair and maintenance activities in traditional railway systems are due to the defections in the ballast layer and therefore most of the maintenance budget is spent on repairing these defects. These repair and maint...
this paper presents the results obtained from the life cycle assessment (lca) of the productionof sicilian artichokes (cynara scolymus) with the aim of reducing impacts, interpreting the results, suggesting possible improvements and enriching the sustainability knowledge already existing in the agro food field. artichokes represent one of the excellent italian agricultural products even if stil...
urban sinks accumulate phosphorus and other elements and may serve as sources of secondaryraw materials. this paper evaluates phosphorus sources based on their environmental impact. in a life cycleassessment (lca) the conventional production was used as a yardstick against which tomeasure the performanceof two recycling options: spreading of sewage sludge and phosphorus recovery from municipal ...
