| pubmed-article:3256516 | pubmed:abstractText | The Authors have taken under study 6 office buildings and a total of 165 work stations with VDTs. Lighting conditions, postures, indoor climate and air-quality have been evaluated, besides worker's subjective approach sounded by individual questionnaire. Concerning visual comfort, it has been noticed that the most simple and well-known rules are often disregarded, such as avoiding to place a screen in front of a light source because of its glare. Also, operators postures are often incorrect, making problems related to their own fixity worse. Air conditioning systems assure almost excellent conditions for thermal comfort, but air changes are often poor and microbiologic quality suffers from plant's inadequate servicing. Finally, the survey of questionnaires shows a complaint percentage which only partly corresponds with the objective data collected, reflecting instead an uneasiness to the kind of work and its organisation. | lld:pubmed |
