Assignment

Part A: Company energy demand

1. Determine the total annual energy demand

  • Obtain the total annual energy demand of your training company (in kWh).
  • If this is not accessible: estimate it on the basis of the partial information available.
  • Are there any strong seasonal fluctuations over the course of the year?
  • Document your data sources.

2. Identify the three largest loads

Record the following for each of the three loads:

  • Name/designation of the device/installation
  • Photo of the rating plate with the electrical characteristics
  • Location in the company
  • Estimated operating times (h/day, days/year)
  • Calculation of the annual energy consumption (kWh/year)
  • Percentage share of the total consumption

Part B: Detailed analysis – fact sheet

Choose one of the 3 loads and create a technical fact sheet according to the following scheme:

1. What does it look like?

  • Description of its external appearance
  • Photos (if possible)
  • Dimensions and weight (if available)

2. What can it do?

  • Main function(s) of the device
  • Technical performance data
  • Areas of application

3. How does it work?

  • Basic operating principle (physical fundamentals)
  • Different designs/types
  • Special features

4. What does it look like inside?

  • Main components and their function
  • Structure (research it, do not dismantle it!)
  • Materials

5. What role does it play in the company?

  • Significance for production
  • Economic significance

Submission

Deadline: 18 October 2025
Format: PDF document uploaded to ILIAS, max. 10 pages

Structure:

  1. Title page (title as above, name, student ID number, company, date of submission)
  2. Part A: Energy demand analysis (approx. 2–4 pages)
  3. Part B: Fact sheet (approx. 2–4 pages)
  4. List of sources
  5. Declaration of independent work (link in the ILIAS course)

Additional notes

  • Respect trade secrets: anonymize sensitive data
  • Safety: no unauthorized measurements on installations
