This thesis is composed of three life-cycle analysis (LCA) studies of manufacturing to determine cumulative energy demand (CED) and greenhouse gas emissions (GHG). The methods proposed could reduce the environmental impact by reducing the CED in three manufacturing processes.

This thesis investigates, from a life cycle perspective, environmental and cost implications of near-term bioenergy applications in the transportation and electricity sectors. Key tradeoffs related to the attributes of the systems are elucidated. Three case studies are conducted to consider the site-specific nature of bioenergy systems. The first two studies analyze the environmental and cost.Learn More

The availability of minicomputers and microprocessors, at a reasonable cost, has provided a significant stimulus in a critical appraisal of fatigue testing and analysis methods. This thesis reviews and extends some of the recent fatigue analysis methods. Two major areas investigated in detail are cycle counting methods and methods for prediction of fatigue life to crack initiation.Learn More
A typical life cycle cost analysis (LCCA) includes evaluating the costs incurred by an asset over its useful life to find the least cost solution. However, since the goals of asset management are to meet level of service (LOS) standards and reduce risk as well, the typical LCCA solution often times does not meet these needs. This has led to the development of the critical LCCA, which meets.Learn More
The present study proposes a thorough approach to the optimization of the whole-life cost of a timber building focusing mostly on its mechanical, structural and energy subsystems for a life cycle.Learn More
The analysis then extends to the other major EU economies as well. To illustrate the effects of fiscal policy on rent-seeking, the exogenous and the optimal (Ramsey) policy cases are compared and contrasted to one another. The main findings of Chapter 3 are: (i) Due to the existence of a signicant public sector wage premium and the large public sector employment, a substantial amount of.Learn More
An economic analysis process known as Life-Cycle Cost Analysis (LCCA) is used to evaluate the cost-efficiency of alternatives based on the Net Present Value (NPV) concept. It is essential to evaluate the above-mentioned cost aspects in order to obtain optimum pavement life-cycle costs. However, pavement managers are often unable to consider each important element that may be required for.Learn More
This PhD thesis will utilise building energy usage in order to compare the life cycle cost and life cycle assessment of different technologies to be retrofitted within commercial buildings. A set of different options will be measured against each other in terms of capital expenditure, incurred financial savings, and total life-cycle evaluation through purchase, installation and on-going.Learn More

He graduated from University of Technology of Eindhoven with a BSc degree in Innovation Sciences. Rob's PhD research at Columbia's Center for Life Cycle Analysis is partly sponsored by First Solar, the world's largest manufacturer and installer of thin.Learn More
Life cycle cost analysis (LCCA) illustrated the savings that can be expected using RCA as a replacement aggregate source as the cost of virgin aggregate increase as the sources becomes depleted. Multivariable sensitivity analysis showed that the LCCA results were sensitive to construction costs, discount rate, and maintenance and rehabilitation quantities. v Acknowledgements I wish to express.Learn More
