abstract
PurposeLiterature review indicates that Leadership in Energy and Environmental Design Accredited Professionals (LEED APs) practicing during the first ten years of LEED in the building industry hold perceptions that have influenced the adoption of LEED. These perceptions may include that some LEED credit points are more difficult to obtain than others, LEED projects have higher first costs, and LEED projects have higher levels of complexity. The literature also indicates that the relationship between these three topics merits research attention, in an effort to discover the magnitude of those perceptions. This paper aims to address these issues.Design/methodology/approachBoth selfadministered questionnaires and interviews are utilized to secure information directly from practitioners. Out of a pool of 8,000 possible interviewees, a total of 102 qualified respondents participated in the crosssectional survey. Statistical Package for the Social Sciences (SPSS) software is used to analyze the data derived from the survey information and to arrive at conclusions.FindingsThe survey identify which LEED credit points are perceived by LEED APs as more difficult, as contributing to higher initial costs and as increasing project complexity. The conclusions indicate a trend toward a higher adoption rate of points that are perceived as having lower initial costs and a lower level of complexity. These findings are primarily due to two reasons: increased cost in managing project documentation; and increased cost in project complexity.Originality/valueThe results of this study can be used by designers, construction professionals, and facility managers who are involved in new construction projects. The trends in credit point adoption, and the professionals' perceptions of their initial cost and level of complexity, may encourage others to consider using systems that introduce sustainability concepts into their design and construction process.
