Abstract

This study investigates the relationship between the LEED BD+C for New Construction (LEED-NC) scores achieved by projects and their scores from each credit category to assess the consistency between the expected and the actual influence of these credit categories in determining the sustainability of a project. The data was collected about all of the built LEED-BD+C for New Construction projects and the relationships between each credit category and the sustainability level of the projects, defined by LEED scores, were evaluated through multiple linear regression analysis. The findings showed the harmony between the expected and the actual influence of the Energy and Atmosphere category and Sustainable Site category in determining the overall sustainability of the projects. However, the three credit categories of Materials and Resources, Indoor Environmental Quality, and Water Efficiency did not show any harmony between the expected and the actual influence on determining the overall sustainability level of projects. The findings of this study illustrate the need for enhancing the consistency between the existing sustainability evaluation criteria and suggests more comprehensive research on the factors defining the level of sustainability of a project.
