Abstract

This study examines the relationship of occupants perception of appearance of their work positions in commercial offices on the occurrence of eye symptoms.The study was carried out in collaboration with the health hazards in buildings research group also known as the LINK programme. Three office buildings with uniform lighting were selected from the LINK programme for investigation. They are Pearl Assurance Building in Cardiff, ODA Building in London, and the Sapphire Building in Reading. The survey was conducted in 1995 over a period of 2 months. In each case study, employees were selected randomly and asked to complete a questionnaire over the period of a given week. A month after the questionaires were completed, physical lighting measurements were made in the relevant offices.The study concludes that; i. the occurrences of eye symptom are related to the occupants perception of the appearance from the work position. The mean analysis shows that occupants with better perception of the appearance from the work position experience fewer eye symptom occurrences. ii. the number of eye symptoms that an occupant experiences does not vary significantly with the occupants orientation with respect to the window, iii. the perception of appearance from the work position does not vary significantly with the occupants orientation with respect to the window, iv. occupants in work positions facing the windows do not have a significantly better perception of their work positions appearance, v. occupants seated facing window do not have a significantly better physicallight attributes, vi. occupants in work positions facing the windows do not have significantly fewer symptom occurrences. vii. the appearance from the work position is not influenced by the physical lighting attributes.In essence, this study concludes that any work position can be satisfactory. The requirement for a satisfactory work position is a good light pattern which projects good perception of the appearance of the field of view, resulting in fewer occurrences of eye symptoms.
