Organisation and examination
Teaching in the first semester, review in January
Schedule
Units courses prerequisite and corequisite
Prerequisite or corequisite units are presented within each program
Learning unit contents
The course provides theoretical bases and methods for carrying out the sizing of energy
systems installed in buildings and evaluating the resulting thermal and energy performance
in the latter. The TRNSYS software and the PVGIS calculator are the simulation tools used
in the course. This course will be articulated between theory and practice.
The course includes the following chapters: General introduction; Climatology, Thermal comfort; Calculation of heating an cooling demands; Modelling and simulation of energy systems, in a sizing context.
Exercices are organized to practive the theoretical notions learned during the courses
Learning outcomes of the learning unit
At the end of the course, the student will be able to size an energy system, using the resources of numerical simulation
He will be familiar with the TRNSYS tool which is a complete and renowned STD software.
He will also be familiar with the Computer Aided Drawing (CAD) tool Google SketchUp 8
Prerequisite knowledge and skills
Background in thermal and energy processes.
Know how to use a computer. - Basic knowledge in Excel. If you are not familiar with Excel, here is a free online
course: https://openclassrooms.com/fr/courses/7168336-maitrisez-les-fondamentaux-dexcel
You must be proficient in Excel to be able to follow some of the labs given during this
course.
If the student wishes to use his personal computer during the practical sessions, he
must make sure to be able to install a computer program on his computer (in this case TRNSYS, the BEMS research team can put available for temporary licenses for students).
Planned learning activities and teaching methods
The course proposes, in alternance, theoretical lessons to present the concepts and practical sessions (sizing, thermal comfort measurement, evaluation of solutions). It also includes a series of lessons devoted to the use of a numerical simulation program (TRNSYS).
The following labs will be organised:
- Introduction to TRNSYS (in 2 parts, the aspects seen in climatology are put into
practice in this introduction to TRNSYS).
- Practical work calculation of the annual requirement in dynamic mode (in connection
with the course on the calculation of demand in dynamic mode).
- TRNSYS 3D practical work: use of the TRNSYS 3D plug-in for the modeling of a 3D building
model and import into the STD TRNSYS environment.
- Wind power practical work: put into practice the aspects seen in the course
ENVT0068-2 "Valorisation of Renewable Energies, Wind power part", with the sizing of a wind turbine in TRNSYS.
- Thermal solar practical work: TRNSYS sizing and simulation of an SDHW system.
- Photovoltaic solar TP: PV sizing with the help of PVGIS.
Mode of delivery (face to face, distance learning, hybrid learning)
Face-to-face course
Additional information:
Face-to-face in classrooms or in computer room (use of the TRNSYS simulation program)

Exam(s) in session
Any session
- In-person
written exam AND oral exam
Additional information:
Oral exam ( open-ended questions ) without course notes
Criteria: capability to retrieve and use the knowledge provided by the course to handle a problem which may occur in real life.
- Practical exam, to be carried out during Q1 and submission of report and simulation files during the January session via the e-campus platform, counts for 1/3 of the final grade.
Description:
You will be asked to carry out a project in the simulation environment of the TRNSYS software, involving the use of the different interfaces of the software. At the end of your simulations, you will have to obtain results, interpret and explain them.
This exam completes the oral evaluation that will take place in the January session and counts for 1/3 of the final grade. The submission of the work consists of a deposit of files on e-campus before a deadline indicated by the teacher. Your submission must include :
Your simulation files (.tpf, .b18, .idf)
A report of the results (maximum 2 pages, preferably in Word format), with a careful presentation of the results, interpretations and conclusions.
The examination is based on the assignment of a simulation project to be carried out by groups of two students. It is a group work (established by the assistant), its preparation will take place during the 1st term of block 2 and the submission of the different simulation files and the results report will be done during the January 2023 exam session with a deposit on e-campus.
Each simulation project is characterised by a complete file containing the main information required for your simulation. Missing information will have to be filled in with justified choices. Each group will receive a file with the information needed to carry out the simulation project.
Criteria assessed: Good application of the notions and skills seen during the various practical exercises. The student will be able to use the TRNSYS tool, encode the different simulation data and create a simulation environment with correct connections between the components. CAD (Computer Aided Design) skills and good use of the TRNSYS3D plug-in. Understanding of the specifics of building thermal and energy analysis in a dynamic simulation environment. Ability to generate consistent results, analysis, interpretation and presentation of results, and to be able to act as a consultant and present a thorough report based on the results, with suggestions for improvement of the initial project.
Work placement(s)
No internship
Organizational remarks
Course organized during the first semester with 2H or 4h periods, combining theoretical lessons and practical work.
Attendance to all practical works is mandatory. Indeed, the first sessions are intended to get to know the TRNSYS software, the rest of the practical work consists in increasing the technicality of the software, the absence of the student to the first introductory sessions to the handling of the TRNSYS software (8 hours of introductory training) strongly harms his capacity to follow the practical work which will follow and more importantly, his capacity to be able to carry out the simulation project which is the subject of the practical examination of this course (and for reminder, counting for 1/3 of the final mark).
