Synopsis:

This course provides an introduction into measurement methods used in building physics. The course consists of three blocks. The first block introduces elementary knowledge in statistics and theory o measurement as a background necessary for processing of measured data, estimation of measurement uncertainty and interpretation of the measurement result. The second block is focused on methods used for measurement of thermal quantities. The physical principles, typical application and limits of selected methods are presented. The third block introduces typical tasks of building design and construction process which solution involves measurement of thermal quantities. Practical classes consist of theoretical exercises of data processing and analysis, laboratory experiments including measurement and evaluation of measured results, educational tours and demonstrations of selected measurement methods.
