Modelling the relationship between green built environment and occupants’ productivity

Purpose The purpose of the study presented in this paper is to determine the relationship and effect of built environment on occupants’ productivity in green-certified office buildings in Sri Lanka. Design/methodology/approach Two research hypotheses were tested by approaching the survey method under the quantitative phenomenon. The questionnaire survey was conducted among randomly selected occupants in three selected green-rated office buildings in Sri Lanka. The survey data were analysed by using the Spearman correlation and ordinal logistic regression analysis techniques to model the relationship existing between the variables. The SPSS v20 software was used in data analysis. Findings The findings confirm the relationship between built environment and occupants’ productivity. As it further proves that, there is a significant effect of built environment on occupants’ productivity in green-certified office buildings. Thus, critical built environment factors influencing occupants’ productivity and their effect were determined. Practical implications The findings could be practically implied as bases to strengthen the evaluation criteria of indoor environmental quality in GREENSL® national green-rating system. Originality/value The evaluation of occupants’ productivity and the built environment factors has been at the focal point of research; however, most studies have focused on single aspects of the built environment. Further, no evidences were found on “which factors” can critically influence the occupants’ productivity in green buildings. The paper, therefore, seeks to fill this gap by proving the relationship between green built environment and occupants’ productivity.
