* Notes: The \(\delta\) effect size is considered to be (i) negligible if \(|\delta|<0.147\), (ii) _small_ if \(0.147\leq|\delta|<0.33\), (iii) _medium_ if \(0.33\leq|\delta|<0.474\), and (iv) **large** if \(|\delta|\geq 0.474\).

Table 5: LEED-CIv3 Energy and Atmosphere (EA) credits category: The median and 25 th–75 th reptiles and Cliff’s effect size (\(\mathbf{\delta_{1}}\)) of the difference between the achieved and the possible points, and (\(\mathbf{\delta_{2}}\)) of the difference between Silver and Gold projects in China and the U.S.  
With respect to China, Shanghai, in which most of the evaluated projects were located, is a megacity with a newly emerging and strong energy policy. For example, the Green Electricity Scheme was launched in 2006 in Shanghai; however, this was unsuccessful in its implementation due to the high prices of green electricity produced by local wind farms and the lack of awareness of the population about the usefulness of this renewable energy source [37]. Similar EA results were confirmed by other authors. [PERSON] et al. [13] analyzed LEED-NCv3 projects and confirmed that the EA category was better performed in the U.S. than in China. High performance achievement of the EA category in U.S. LEED-Civ4 projects was also confirmed by [PERSON] [38], who stated that EA achievements increased from level to level with the following median \(\pm\) interquartile range (IQR, 25 th-75 th percentiles) achieved points: 12.0 \(\pm\) 4.0, 14.0 \(\pm\) 7.5, 22.5 \(\pm\) 13.0, and 31.5 \(\pm\) 7.5 in the Certified, Silver, Gold, and Platinum projects, respectively.
