|
| Course description :
This course includes special matters in building acoustics and lighting techniques that complete the introductory course ELEN0077-3. More precisely, the techniques that can solve the most frequent problems in room acoustics and sound insulation in buildings are described and applied.
Contents :
- room acoustics: wave-based, statistical and geometrical approaches
- air-borne and structure-borne sound insulation
- room acoustics project
- introduction to colorimetry
- luminaires
- interior artificial lighting design
- daylighting |
|
Learning outcomes of the course :
|
| At the end of the course, it is intended that the student will be able to:
- understand the effects of eigenmodes in rooms and determine their frequencies,
- calculate and measure reverberation times,
- identify the most frequent problems in architectural acoustics and propose solutions,
- propose and apply simulation models in room acoustics, in order to reach well-defined quality criteria (RT, EDT, D50, C80, etc...),
- identify the most frequent problems in building sound insulation and propose solutions,
- evaluate the transmission index of simple walls,
- identify the main properties of lamps and luminaires that are used in a lighting project,
- design an artificial lighting installation for an interior space,
- evaluate the amount of daylight available in an interior space, depending on its dimensions, the location and area occupied by the windows. |

Prerequisites and co-requisites/ Recommended optional programme components :
|
| ELEN 0077-3 (30h + 15h) |
|
Planned learning activities and teaching methods :
|
| The first part of this course is organised in modules, each of them consisting in a general presentation ex cathedra, followed by applications and exercices with the teacher. Sometimes, these exercices are included in the general presentation.
Some labo demonstration can be organised, if possible.
In a second part, it is intended to carry out a project in room acoustics. During this project, the student will use a room acoustics software in order to reach well-defined quality criteria for his/her room model. This project will be concluded by a report.
It is recommended that the students actively participate to the general presentation by answering questions and formulate critics. Also during the exercices, the students must be equipped with a calculator.
It is also recommended to read and understand the theory and exercices of the previous lesson before assisting to the next one. Additional exercices will also be proposed: it is strongly recommended that the students try to solve them by themselves and ask the teacher to evaluate their solution. |
|
Mode of delivery (face-to-face ; distance-learning) :
|
| Face-to-face learning.
The project is supervised by the teacher. The mode is to be defined following the availability of computers. |
|
Recommended or required readings :
|
| The students must have the following book (available at the students' Centrale des Cours):
(in french)
- Acoustique du bâtiment (J.J. Embrechts 2008).
For the "lighting techniques" lessons, ask the teacher. |
|
Assessment methods and criteria :
|
| The evaluation is first based on an oral examination during which the student will answer to questions concerning the theoretical matters that have been exposed during the presentations ex-cathedra. He/she will also solve one or two exercises (bringing a calculator is essential).
All books and notes can be consulted for the solution of exercices, except if otherwise stated.
Finally, the report of the project in room acoustics is also part of the evaluation. |
|
Organizational remarks :
|
| This course is organised during the autumn semester.
