Learning unit contents

  • Preamble
The energy optimum, in the sense of the first or even the second law of thermodynamics, can't lead to the best choice (optimal choice) of realization of an energy installation (choice of investment). An investment in energy saving must last several years during which the value of the currency is modified. Direct calculations of go-no-go for such investment and the optimization calculations of installation (dimension, functioning parameters,..) must take into account both scientific and economic aspects. All energy sectors are concerned. The financial (economic) costs of acquiring the facilities (CAPEX) , their cost of operation and maintenance (OPEX), and the cost of capital play a decisive role. It is necessary to know how to mix with rigor the aspects of the sciences of the engineer (thermodynamics, thermal, mechanics of the fluids) with the financial computations. The methodologies to be acquired in this course can be applied to the other domains of the engineering sciences.








  •   Objectives and content of the course

    - How determine the profitability of energy investment?
    - How to compare two energy investments, and make a choice?
    - What is the Net Present Value (NPV) of an energy investment
    - The Time of Return, a concept to handle with care
    - The Internal Rate of Return (IRR) of an investment.
    - Optimal achievements. Optimal dimensioning of installations from simple to complex: optimal thermal insulation thickness, the diameter of a fluid pipe, ..
    - Thermoeconomy and energy integration.
