Course summary

Advanced Energetics 2025-2026

Lectures + Project ( Monday: 14h15 - 19h00); Office hours (Thursdays 14h00 -16h00)


Instructor: 
Prof. François Maréchal

Assistants: 

Dr. Daniel Flórez-Orrego, Vibhu Baibhav, Pullah Bhatnagar, Federico Cazzulani


Introduction
The course is project-based: you will complete an energy efficiency analysis project in a group. Each week, we will provide you with the necessary theoretical background to solve your project's tasks. You will then receive tasks to be performed and synthesized within your group to write the final report for the project. The project will serve as the basis for the quizzes and the final exam. You can go through this GUIDE BOOK to know the different steps and milestones for your project. 

This course consists of the following sections:

  • Lecture, where you learn the theoretical concepts needed to handle the problems in the project.
  • Quiz, during the semester five quizzes are planned to help you understand the theories (the exact date of each quiz is in the planning table below). 
  • Project session, where you will work on your project and interact with Prof. Maréchal and TAs if you have any questions.

The course will cover the following milestones:
  • M1: Mass and energy balance of the CIP unit, energy bill calculation.
  • M2: Minimum energy requirement and heat exchange network design.
  • M3: Heat pump introduction and Utility integration in the energy system.
  • M4: Exploring Synergy with the Dairy process, Reporting Symbiosis benefits
  • M5: Valorization of waste product (Literature review) and reporting the benefits

TA's availability
TAs are available on Mondays during the allocated hours.
'Office' hours will take place on Thursdays. If a group would like a session, a message requesting it should be sent at least the day before with a list of questions/doubts. Last minute questions will not be answered during Office hours.

Grading

The evaluation of your work includes three sections:

  • Project report (50%)
  • Report review (15%). Comments: you are required to review the report of one other group and write a peer review on how they can improve their work.You will receive the group's report at the end of Semester (W4 Dec'25) and will have to submit your review file before the start of exam session (W2-W3 Jan'26)
  • Quizes (10%). Comments:4 distributed across the semester.
  • Written exam  - required (25%), where you will be asked to explain the methods and tools you used to complete the different tasks of the project.

Your final grade will be the weighted sum of these different sections.
Sections Weights  Grade (example)
Project report (with contribution evaluation) 50% 5.00
Report review 15% 5.25
Quizzes 10% 5.75
Written exam 25% 4.00
Total 100% 4.86

Forum

During this course, we will be using Forum for all of the communications. 

Quiz

You can find the quiz here

Flip classes

During the flip classes, questions are assigned to each group and should be answered in 1-2 min. You are free to split the questions within the group members. When it is your turn, connect to the zoom link here, share your screen and answer the question. You can stay at your table while answering the question.

Project materials

Each group will be assigned to one project and two main tools will be used for collaborative work (you DO NOT need to install them in your VMs, as they have been already installed by our IT experts):


    • Quarto - A friendly coding and reporting framework.
    • Git - a collaborative platform to share your report among group members and TAs.

The idea behind the report template is that, by updating it on a weekly basis, the final report is progressively assembled and corrections can be applied before the final version. All the templates are provided in the form of a git repository. Therefore, it is necessary to know the basic set up of git for this course.


USEFUL LINKS
Detailed project descriptions will be available here
The VMs are accessible using VMware Horizon on the server https://vdi.epfl.ch under the name STI-FM-cours-2025

Additional info:
    • Inside the 'useful material' folder you will find publicly available literature, in particular, papers, charts, etc.
    • Some of the mentioned useful references are books, which are not available for Moodle sharing. In particular Turton and Perry Handbook; the former is available up to the 4th edition, while the latter up to the 8th edition. Both are at EPFL library for request and consultation. Digital versions can be found though.

Report & Review section

Submission Section 

Final report submission:  Due Date - (19.12.2025). You only need 1 submission per group.To submit your report, wrap all your html files from the _book folder into a zip file.

Review submission: Due Date 11. January Only put your name and sciper on an extra (first) page. Do not put your name/sciper anywhere else in the document. Write a 2-4 pages review. Start with an introductive overview on the project and general recommendations on the report. Then, continue with more specific comments (try to group them by categories). Justify your comments and discuss the outcomes of the report with a critical thinking. Most important, be respectful and raise relevant feed-backs.



Good luck!!


Final Exam

You will find below the schedule (updated) for your oral exam, if you have any concerns, please contact the TA as soon as possible

- The exam will take place in room ME A2 465 from the 14th to the 16th of January 2024.
- The exam will start with your short 3-minute talk about your project. Then prof. Maréchal will ask you questions on the theory of the course. Only prof. Maréchal will ask questions. The 2-3 other experts will only record and grade your answers.
- During the exam, you will have a screen with your own summary of your project (on Miro). You can also put some theory notes and equations on it to support your answers to the theory questions. A good advice is to avoid covering your summary with the whole course, since it usually disturb the explanation, make it unclear and make the student lost in the summary.
