Figs. 6-8 depict the histograms and CDF for the 3 analyzed scenarios: (1) personal (2) social and, (3) both personal and social. Fig. 6 indicates that, with 90% of confidence, the personal sector obtains a NPV of up to $5715/m2 ($531.62/ft2). Nevertheless, the most likely benefit is $611/m2 ($56.84/ft2). Additionally, there is a probability of 1.0% that the NPV results in a cost, not a benefit. Therefore, there is 1.0% confidence that intensive green roofs could cause losses of up to $346/m2 ($32.19/ft2). Fig. 7 shows the social benefit of intensive green roofs. The most probable social benefit is $62/m2 ($5.77/ft2) and the maximum possible benefit could be $571/m2 ($53.11/ft2), with a 90% confidence. The combination of personal and social factors represents the overall economic benefits of installing intensive green roofs. Fig. 8 shows that the most probable benefit of intensive green roofs is $696/m2 ($64.74/ft2).
