In this regard, present study aims to assess the economic justification of green roofing in Tehran. Considering two criteria of air pollution and green space per capita, district 2 of the municipality was selected which is a host to a variety of social and economic classes. Discrete choice experiment(DCE)method was used to determine the economic value of green roof environmental services. In addition, Net Present Value(NPV),Internal Rate of Return(IRR), and Benefit-Cost Ratio(BCR)indices were utilized for Cost-Benefit Analysis(CBA)of green roofing.Based on the results, citizens were willing to pay an average of 182.1 $/m2 to enjoy the aesthetic and environmental benefits of the green roof.Moreover, green roofing in the study area was economically justifiable so that the average IRR was 44% and NPV was $187during 2020.However, the IRR increased by175% to an average of121% considering the environmental benefits of this technology and the NPV grew by about 388% to $914. | ||
