Abstract
Leadership in Energy and Environmental Design Commercial Interiors (LEED-CI) versions 4 (v4) and 3 (v3) Silver and Gold projects have been widely used in both the U.S. and China. This study aimed to compare the LEED-CI-Silver and LEED-CI-Gold v3 and v4 in China and the U.S. The design of the study comprised two stages: (1) to identify all LEED-CIv4 projects in China and the U.S. at the Silver and Gold levels for 2014–2019; and (2) to collect the same number of LEED-CIv3 projects for each certification level from the same cities of China and from the same states of the U.S. at the same times, if possible. Cliff’s δ or the log odds ratio effect size was used to evaluate the difference between the achieved and the possible points, and the difference between the Silver and Gold projects in China and the U.S. The results show that, in the Silver-to-Gold transition, in China, the water–energy–site–human health saving strategy was used, while in the U.S., only the water–energy saving strategy was used.
Highlights
Green building certification is a common approach to building in a sustainable way.Due to the differing existing environmental, political, economic, social, and technological contexts of different countries, it is accepted that appropriate green rating systems can be developed for specific countries
Castellano et al [3] analyzed Leadership in Energy and Environmental Design (LEED) sustainability aspects and confirmed that 83% of the credits are related to environmental sustainability, 16% of the credits deal with social sustainability, and 1% of the credits refer to economic sustainability
Similar results were presented by Illankoon et al [4], who concluded that LEED devotes 74.59%, 18.03%, 0.82%, and 6.56% of credits to environmental sustainability, social sustainability, economic sustainability, and others, respectively
Summary
Due to the differing existing environmental, political, economic, social, and technological contexts of different countries, it is accepted that appropriate green rating systems can be developed for specific countries. Some country-specific systems have received much attention in foreign countries; the most prominent example of such a foreign-accepted system is Leadership in Energy and Environmental Design (LEED). This system was initially developed (in 1998) in the U.S by the U.S. Green Building Council (USGBC), a non-profit coalition of the building industry [1]. According to [2], sustainability should encompass environmental sustainability, economic sustainability, and social sustainability. Similar results were presented by Illankoon et al [4], who concluded that LEED devotes 74.59%, 18.03%, 0.82%, and 6.56% of credits to environmental sustainability, social sustainability, economic sustainability, and others, respectively
