electrical installations.
• Modern household electrical installations (EIB / KNX).
Study and design of electrical installations with a computer. The
student is required to
complete a series of selected laboratory exercises in the above
material. In addition, the
student is required to prepare and submit at the end of the
semester a written assignment
on the subject of electrical design of a building.
Upon successful completion of the course the student will be able
