Synopsis:

Thermal performance of buildings

Basic course on building physics. The first part of the course (lectures 1, 2) introduces basic principles of heat, air and moisture transfer in buildings and building components as a necessary background for further studies. The second part of the course (lectures 3 to 6) provides an introduction into the design and construction of buildings and building components with respect to building physics related issues. Typical tasks of building design and construction process related with the topics of the course will be presented as well as methods for their solution. A short information on selected diagnostic used for assessment of thermal performance of buildings methods will be presented.

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 acoustics, the listener is first introduced to the concepts of sound and noise, sound perception, basic quantities, sound sources and corresponding limits. The propagation of sound in the free and diffuse field, the propagation of sound through an obstacle or in the ear canal is also discussed. When assessing or designing the interiors of buildings, knowledge regarding sound absorption structures and sound insulation properties of dividing structures will be applied.

Requirements:

Elementary knowledge on physics corresponding to the secondary school level.

Syllabus of lectures:

The schedule of lectures may change. It will be announced at the opening lecture whether the course starts with thermal performance, acoustics or daylighting part.

Study Objective:

Thermal performance of buildings:

The student will be provided with a basic theoretical knowledge necessary for further studies of building physics. The student will be able to:

- solve elementary problems related with the heat, air and moisture transfer in buildings and building components

- solve elementary tasks of the building design process (calculation of thermal transmittance, assessment of surface and interstitial condensation, etc.)

- design technical solutions for reliable building components and energy efficient buildings avoiding the risk of failures due to deficient hygrothermal performance

Sun exposure, daylighting and acoustics:

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