Course abstract

Course of study includes information about parameters of optical radiation, electric lightning devices, as well as classification of necessary kind of lighting. Students are acquainted with types of the water heaters and heat pumps. Discussed about the basic of space ventilation as well as the classification of the ventilation system. Students performs the analyses of different sources of light, learn PC programs for lighting calculation.

Learning outcomes and their assessment

Knowledge: about types of electric lighting and basic concepts of it, about design of electric technology and operating principles of it – exam; Skills: choose a particular study and exploration of appropriate calculation methods, justifying the choice of the interpretation of the data results – test; to formulate and critically evaluate the basic issues of lighting and electrical technology projects study; define the results of the appropriate conclusions – exam; Competence: to do the electric lighting (for inside and outside) and electrical technology calculations and activities using a specially provided software, analyse the results – exam.

Requirements for awarding credit points

Written exam.
Exam consists of:
Two questions of the theoretical part;
The task of the topics learned in the study course in practical works;
The task of the topics learned in the course of laboratory work;
The student is admitted to the examination only if all tests are counted.

Criteria for Evaluating Learning Outcomes

Evaluation of study results is based on the student's answers during the examination. It is also possible to get a maximum rating of 10 (excellent) if all the work is done on time, and the student has given the appropriate knowledge.
