IMPROVEMENT OF WORKPLACE ERGONOMICS IN ATRIUM-TYPE BUILDINGS

The aim of the study was to improve the indoor quality and ergonomics of workplaces in atriumtype buildings. The investigated atrium-type building has the atrium (15×30 metres) inside. The roof of the atrium is built from glass and there is a break between the walls and the roof. It gives the possibility for workers in rooms closed to the atrium to have some fresh air. Nevertheless, there are problems caused by shortage of natural light, high concentrations of CO2 and low room temperature in winter. The main results of the investigation were: the design of the workplaces needs to be carried out in parallel to the construction of the building; later it is difficult to improve conditions in the workplace; the air temperature in workrooms depends on the room location in the building and in winter, rooms closed to the atrium are cold; the concentration of CO2 exceed limits in rooms where windows cannot be opened. Workers are endangered by developing sick building syndrome. The concentration of dust is under the limits, but the problem of dusty air was raised by the workers. Some ergonomic improvements are possible and corresponding recommendations were given to the employers.
