Abstract

Natural lighting creates a pleasant environment, promotes healthier conditions and saves energy, and is an important factor in the design of education institutions. Many research indicates the positive impacts of better daylighting integration in educational spaces for student’s health and wellbeing.  For this research, an in-depth lighting integration analysis was carried out in three typical classrooms in Berrewaerts college Kandy, Sri Lanka. A field study comprised of a questionnaire-based survey and measurement of illuminance was combined with daylight simulation using Autodesk Ecotect 2011 & Autodesk Revit. The study reveals that lack of awareness in integration of natural light with the design can either result in increasing the negative effects of excessive daylight exposure or lack of adequate daylighting. In upper levels and east facing classrooms the main problems were associated with high levels of daylight such as excessive shadow and light patches, uneven light distribution and color distribution and impede perception of objects and text. At ground floor level and south facing classrooms, when natural light is not properly integrated with the design resulted in uneven light distribution, non-uniformity of light resulted in difficulty in reading at work plane and impede the visual perception of objects and text.
