Elective at semester(s) 6, 8, ECTS: 3
Generic Competences: Ability to search for, process and analyse information from a variety of sources using the necessary technologies, Ability to work autonomously, Ability to work in an interdisciplinary environment, Ability to design and manage projects.
Knowledge, Comprehension, Application, Analysis, Synthesis, Evaluation
The course objectives after finishing the lectures/exercises are:
1. Familiarity with current technology. Making the standards for the appropriate technology to be applied in the design according to the requirements.
2. Basic knowledge on the biological impacts of lighting.
3. Taking control of the lighting system design process to make sure both regulatory and aesthetic requirements are met. The students practice with basic equipment and at the same time learn to use the relevant software tools.
4. Awareness of the daylight and artificial light interplay and its effect on the energy balance of the building.
The course presents the basic design principles and regulatory requirements for lighting design in the built environment.
The course consists of a number of lectures with accompanying exercises in each section and is structured as follows:
1. Lecture #1: Introduction. Design evolution and contemporary requirements that need to be met. Emphasis on quality while achieving low energy consumption. Discussion of the biological background of practices, countering lighting within the framework of energy regulations. Examples.
2. Lecture #2: Visual system, perception, and color.
3. Lecture #3: Basic principles of photometry. Quantities and units. Exercise.
o Laboratory: Instruments for measuring lighting and brightness. Their use
4. Lecture #4: Use of the above quantities in design practice.
5. Lecture#5: Technology: Light sources. Principles of operation of light sources, regulations related to the measurement of their characteristics.
o Laboratory: Demonstration of light source operation
6. Lecture #6: Luminaires. Classification, Principles of reflector design. Analysis of photometric diagrams.
7. Lecture #7: Design theories. Review .
8. Lecture #8: Calculations. Detailed presentation of the Lumen method as well as presentation of all methodologies used in lighting calculation algorithms. Presentation of software capabilities (RELUX & DIALUX software are used). Exercise
9. Lecture #9: Functional lighting. Investigation of the requirements of standard EN 12464-1,2. Exercise
10. Lecture #10: Daylighting. Basic definitions, availability, presentation of design techniques.
o Workshop: techniques for assessing the visual environment in relation to glare (HDR photography).
o Workshop: Use of artificial sky/sun using models
10. Lecture #11: Energy saving techniques. Assessment in the early stages of design of the percentage of savings from the use of natural lighting in accordance with EN 15193-2007.
11. Lecture #12: Basic economic analysis. Payback period, net present value. Comparison of lighting systems based on IES RP-31-14 "Recommended Practice for the Economic Analysis of Lighting."
·12. Lectures #13 & #14. Design requirements for spaces (offices, museums) and outdoor spaces. Exercise.
1. Completion of exercises during lectures (small project with specific requirements (individual) during the course)
2. Final submission of a project related to the design of a building lighting system, accompanied by an oral examination.
