Lighting and health of building occupants: a case of Indian information technology offices

摘要

This pilot study explores the possibility of using architectural design to positively influence the health and well-being of information technology (IT) professionals using more daylight in their offices. Literature review, visual observation, office lighting survey and illuminance study at the premises of two IT companies in Kolkata, India indicated common health issues of their occupants which can be more critical than sick building syndrome. This can be possibly linked to disruption of the circadian clock or in turn lack of exposure to daylight and its natural variation. Mere 18% contribution of sunlight in the indoor illuminance affirmed this point. Bespoke space planning and fenestration design to allow more daylight without compromising the privacy were set as the goals of a further study to augment the latest research in healthy office lighting.
