"Daylighting" part

The 6 hours course dedicated to daylighting allow to tackle the necessary basic notions required for the LICAR 1605 workshop, that is, the main photometric quantities and the metrics used in daylight.
Then, daylight strategies are approached, with notions of glare and the means to protect from it.

"Thermic and hygrothermic" part

The course starts with a reminder of the several heat transfer modes. Base on that, the way to evaluate the heat transmission through a wall in static mode can be detailed. Then the students get to learn how to draw the evolution curves of these temperatures within a wall.
Based on the diagram of moist air, students are then taught how to trace the vapor pressure curve within a wall and how to accurately assess the internal condensation risks. Then, the protection methods against that condensation are approached.
Finally, the surface condensation phenomenon and its consequences are studied.


"Acoustics" part

The content is based on the implications of construction practice of the goal criteria of acoustic comfort of the buildings. These criteria are the common thread through the course. Five major themes of the building acoustics are successively developed:

  1. basic principles of acoustics and noise of the technical equipment,
  2. reverberation and acoustic correction,
  3. impact sound insulation,
  4. airborne sound insulation,
  5. façade sound insulation.

For each of these five themes, the following aspects will be developed: theoretical notions, normative criteria, principles of dimensioning (prediction of building performance from the performance of the constituting building elements), examples and application exercises, practical case studies (analysis of building specifications, aspects of costs and constructive risks, visualization of execution details on site).

"Building and performances" part

The 30 hours of the course are dedicated to a constructive reflexion through technical detail practice. The first 9 courses aim at understanding the constructive principles of the building (mainly the individual housing) and their implication in the conception of the architectural project, by reviewing:

  • Infrastructures and buried constructions
  • Inner surfaces and walls
  • Floors and slabs
  • Façades and outer surfaces
  • Roofs
  • Openings and windows
  • Staircases.

This theoretical part is followed by a group workshop (individual housing) aiming at developing:

  • The understanding of the stakes of one particular project (structure, insulation, tightness, façades aesthetics')
  • The understanding and analysis of a building's technology:
    - How does one build a surface, a building?
    - Which are the important elements?
    - How do the different layers articulate?
    - How are connexions executed?
  • The understanding of the influence of technology on architecture: how to use the technical detail as an architectural design tool
  • The understanding of the development of and architectural project through the selection of materials, of the building processes and their performances (technical and environmental)
  • The capacity to design and draw the several details (plans/sections) techniques of a particular project
Teaching methods

 The daylighting and thermic and hygrothermic parts are lectures.

For the acoustics part:
Lecture illustrated by PowerPoint slideshow (theoretical aspects, exercises, material performances, prediction methods, execution details, practical examples of project dimensioning).

The building and performances part:

  • 9 lecture courses, each one divided in three parts:
    - An interactive and in common reflexion on the 'how to build'
    - Theoretical teaching of the constructive technology
    - Technical documents research (to be done by the students at the end of each course to put together the documentary file)
  • 6 workshops to apply theoretical principles to an individual housing architectural project: design of the walls composition and technical details.
Evaluation methods

The "daylighting" and "Thermic and hygrothermic" parts are assessed with a written exam. The goal is to assess the basic concepts knowledge. Regarding thermic and hygrothermic, the students will have to be able to apply theory to simple case studies.

The "acoustics" part is assessed using a written test in two parts. 25% theoretical part (a question among previously known type questions) -75% exercises part with formulary.

The "building and performances" part is assessed using two works (one group work and one individual work) :

  • Group work: based on plans, sections and photographs of houses designed by Belgian architects (documents provided by the teacher), students (in groups) are expected to re-draw the plans and sections at a 1/50 scale on a computerised support, to realise a full section at 1/20 and two technical details (sections/plans) at a 1/10 scale.
  • Individual work: creation of a documentary file, including the technical sheets of the main materials, technical details proposed by manufacturers (window frames, tightness, internal and external coatings') and the environmental documentation of the main materials components of the walls seen during the course.

The students have a syllabus and copies of the PowerPoints slides used during the course.
