Abstract
The paper deals with the important element of proper lighting conditions at a workplace. The case study has been focused on the intelligent building “Energis” of Kielce University of Technology, where the experimental tests took place. Several groups of volunteers filled in the questionnaires related to their subjective feelings of lighting conditions in lecture rooms at different seasons. Simultaneously, precise measurements of lighting intensity were carried out. The comparison of the expressions of the room users and the measurements enabled to draw conclusions about the conditions provided in the intelligent building related to lighting. The study provides valuable information of lighting conditions in the modern, intelligent buildings which are more and more common throughout the world and serve various purposes such as office, educational or other public utility buildings.

Summary
Daylight and artificial lighting is one of the basic elements of the working environment in a workplace. It is a factor which has a significant impact on comfort, productivity and quality of work, and above all on its safety. Illumination enables a worker to perform his duties without feeling tired or having to use excessive strain on his eyes. Both excessive light and not enough light can have serious consequences for our health. A person experiences visual discomfort by the over brightness of general illumination, the appearance in the field of vision of a light source with a brightness significantly different from the general illumination, and flicker - a frequently changing light level. It reduces the level of concentration and efficiency of the employee
