Occupants’ satisfaction on green certified factory buildings in Sri Lanka

Abstract

Factory buildings play an important role in socio-economic environment in Sri Lanka while significantly contributing to the resource consumption. Therefore, the application of green building concept, which ensures the well-being of both human and environment is crucial to this end. While leaving a lighter footprint on the environment, a successful green building should be able to meet the classical building design concerns of economy, utility, durability, and comfort requirements. The occupants‘ satisfaction also needs to be given a special attention as it directly relates with the occupants‘ productivity. However, a lack of concern on the occupants‘ satisfaction can be seen in green factory buildings in Sri Lanka and thus, the research aimed at investigating the occupants‘ satisfaction and identify the causes for dissatisfaction if any. A semi structured questionnaire survey was conducted among total of 50 occupants selected from five green factory buildings in order to identify their level of satisfaction. The Mean Weighted Rating method was employed for data analysis. The research identified that the satisfaction level of occupants is at a good level though the occupants‘ dissatisfaction in green factory buildings was mainly caused by difficulties engaged with adjusting the light, room temperature, and room ventilation levels.
