User Experience and Perception in First-Generation Green-Rated Office Buildings in India

Abstract

This study explores the ubiquitous links between human behavior and perception of first-generation green buildings in India. It is generally assumed that similar rated green buildings should invoke similar levels of user satisfaction. However, this remains significantly under-researched in case of India’s first-generation green buildings. The level of user experience and perception is studied through a five-point occupant questionnaire survey across three similar green-rated office buildings in India. The case study buildings are located in Delhi-NCR and lie in the same climatic zone. Twenty-five attributes related to user satisfaction are taken into consideration. The questionnaire responses are statistically analyzed using data reduction method of factor analysis to understand the latent variables that affect human experience. The results indicate that there is significant non-uniformity in the user experience and perception. The study suggests that human behavioral aspects should be considered in the design process as only physical attributes and environmental factors may not be sufficient to evaluate the performance of a green building. The broader aim of the study is to create higher acceptability of green buildings among the users that would enable across urban sectors.
