Synopsis:

Lighting technology deals with two main parts, sun exposure and daylighting. In the first part, the listener will learn which objects are subject to requirements and what are the options for verifying the time of insolation. This part also includes the connection of the results with possible boundary conditions.

The second part deals with the assessment of daylight mainly in the interiors of buildings with regard to the gradation of sky brightness, shading conditions and the characteristics of the room and the lighting opening.

In building acoustics, students are first introduced to the concepts of sound and noise, sound perception, basic quantities, sound sources and corresponding limits. The next part of the course deals with sound propagation in free and diffuse fields and sound propagation around barrier. Particular attention is paid to the sound insulation properties of partition structures and sound absorbing structures.

Syllabus of tutorials:

1) Assessment of the sun exposure of the selected apartment or family house using the shading diagram.

2) Verification of the insolation of the selected apartment or family house using a rectangular or stereographic solar diagram.

3) Assessment of daylight in a living room or in a room with permanent residence of persons.

4) Propagation of sound in outdoor space.

5) Propagation of sound in a room.

6) Calculation of sound insulation of a building element or between rooms.

Study Objective:

The ability to solve basic practical problems of sun exposure, daylightling and acoustics and to apply the results in practice.
