Entry Knowledge

Fundamentals in building design and building physics - acoustics and optics.

Aims

Fundamentals in room acoustics, determination of air-borne and impact sound insulation index for building constructions, design of rooms and their interiors with respect to the reverberation time. Determination of requirements for indoor acoustic comfort and design of building protection against exterior noise.
Methods for the evaluation of visual comfort in buildings, daylighting and insolation of buildings.


Reports of building acoustics and daylighting and insolation tasks.
Tasks from reports will be applicable in study projects.
