1 Energy Made-to-Measure in textile and clothing industry Energy Saving tools for Textile/Clothing Manufacturing A quick introduction Samuele Branchetti ENEA CROSS-TEC 1

2 Outline Energy Saving Scheme (ESS) EDST EMBT SAT Energy Consumption Reduction Tool Consumption analysis Investment evaluation Examples 2

3 Energy Saving Scheme (ESS) The Energy Saving Scheme ESS is supported by three Excel based tools, which are: Energy Distribution Support Tool EDST Energy Management and Benchmark Tool EMBT Self Assessment Tool SAT 3

4 EDST- Energy Distribution Support Tool How and where is energy being consumed? To understand the organization s energy matters the best tool is an energy audit, which should be conducted by internal or external specialists by means of consulting. If an audit is not feasible, an internal approach can be made in order to access energy flows using the EDST. The EDST allows to input technical and work load data and produces the electrical and thermal energy distribution by use type and productive process/section. 4

5 EMBT - Energy Management and Benchmark Tool What is the energy content of my product? What is the carbon footprint of my product? How can I evaluate my consumption on a regular basis? How is the company performing, energy wise, when compared with its counterparts? The EMBT allows to match the company s energy bills and production data to calculate energy indicators and report on the evolution of consumption: regression analysis (energy vs. production charts) benchmark, based on data collected in five countries, Bulgaria, Germany, Italy, Portugal and Romania monitoring of energy indicators by continuing to use the tool month by month and checking evolutions 5

6 SAT - Self Assessment Tool A tool for an energy check-up: to analyze the energy consumption of own company to select a list of energy saving measures and costs reduction to evaluate the saving achieved by energy efficiency improvement does not replace an energy audit conducted by specialists 6

7 SAT / ENCORE 7

8 SAT / ENCORE Consumption analysis It provides energy consumption and cost indicators compared to benchmarks for each kind of production: consumption and cost / turnover (Eurostat benchmarks) energy consumptions distributed by source specific electrical and thermal consumption by product/productive process (ARTISAN benchmarks) total CO2 emissions It identifies saving measures to reduce energy consumption: list of recommended Best Practices 8

9 SAT / ENCORE Download 9

10 SAT / ENCORE Consumption analysis Example: a clothing company sewing machines and ironing presses turnover of Euro ,00 production of units electricity and natural gas consumption 10

11 Example: SAT / ENCORE Consumption analysis company that leads a steaming process of yarn finishing activities high using of thermal energy customized products turnover of Euro ,00 electricity and natural gas consumption 11

13 ENCORE Investment evaluation Is the energy efficiency improvement profitable? A specific module is available to make a cost-benefit analysis: for assessing the ability of an investment to offer a net benefit to select the best choice out of many solutions costs and benefits estimated in monetary terms and discounted for the time value of money 13

14 ENCORE Investment evaluation NPV Net Present Value NPV = CF n j= Ti j I 0 IRR Internal Rate of Return DPB Discounted Payback Period PI Profitability Index The rate that sets the NPV of the cash flows equal to zero (the discount rate at which the costs equals the benefits) The amount of time that sets the NPV equal to zero, i.e. the years required to cover the cost of investment The amount of value created per unit of investment Sensitivity analysis The variation in the NPV under different values of input Ti, CF, n e Io 14

15 ENCORE Investment evaluation Example: cogeneration improvement Present situation Ameliorative situation A Revamping of cogenerators Ameliorative situation B Replacing of cogenerators Cogeneration plant that includes n.2 identical cogenerators running since 15 years Need of an in-depth updating Updating of cogeneration units in order to bring them back to the rated operating conditions Replacement of cogenerators with new plants that provide the same rated power Efficiency to 33-34% due to wear Efficiency to 37% Efficiency to 40% 15
