“…The benefit-cost analysis was used to evaluate the economic feasibility of green roofs in many cities in North America, Europe, and Asia. These cities include New York [16], British Columbia [17], Genoa [18], Helsinki [3,13], Hong Kong [15,19], Seoul [7,20] and Kuala Lumpur [21]. The results reported by previous studies are pretty different.…”

“…However, as their results have been very different, the demand for future research has continuously increased. This is not only because the costs and benefits related to green roof constructions differ due to supply and demand, but because other criteria differ as well, including climate, economic circumstances and government policies, which affect the estimation process [9,21]. The previous studies used approaches other than benefit-cost analysis, such as a Monte Carlo simulation approach [21], probabilistic economic analysis [28] and life-cycle cost analysis [6,29].…”

“…Researchers in Kuala Lumpur used a Monte Carlo simulation approach to provide a good comparison between their results and those of previous studies due to differences in climatic and physical conditions [21]. Perini and Rosasco (2013) evaluated the economic sustainability of vertical greening systems in Genoa, Italy, through benefit-cost analysis [18].…”

Green roofs, which have various economic, environmental and social effects, have been acknowledged as an alternative green space in urban areas. This study aims to investigate the economic feasibility of green roof projects by conducting a benefit–cost analysis on the case of Jung-gu, Seoul. The analysis estimates and compares five different scenarios applied in the study area with a 20-year operation period in all cases. This set of scenarios aims to compare the most idealistic situation with more achievable and realistic situations, to provide policy implications for green roof initiative projects in Seoul. The analysis consists of estimating six cost items and eight benefit items. Among the benefit items, two non-marketable elements are estimated by the contingent valuation method. The scenario with 100% application of a green roof, has benefits exceeding the costs with a benefit–cost ratio of 1.174. However, the other scenarios with certain prerequisites have a benefit–cost ratio that is very close, but still smaller than 1. Therefore, it is possible to claim that green roof initiative projects are economically viable under specific conditions. However, there are many restrictions to engaging in green roof constructions for entire building rooftops.

“…It is found that, if built right, green roofs can be the least costly option for roofing in a 25-year perspective. In Mahdiyar et al [85], the NPV and payback time of extensive and intensive green roofs in Kuala Lumpur are analysed. They are both found to be a low-risk investment, the extensive more so than the intensive.…”

Performance of Blue-Green Roofs in Cold Climates: A Scoping Review

et al. 2018

View full text Add to dashboard Cite

Green and blue-green roofs are emerging as an increasingly popular feature of rooftops, particularly in urban areas. Particular problematic conditions render their usage complex in the Nordic countries. In order to ensure that green roofs are built durable and with the service life expected of them, it is important to know all the relevant factors surrounding their construction and operation. A scoping study was conducted in order to gain an overview on green roof research and available scientific literature. One hundred articles of particular interest for Nordic climates were retrieved and their findings summarized. It is found that the vast majority of green roof research has been conducted on a theoretical basis, or with practical measurements on green roof test beds or isolated components. There is scarcely any literature on the operation of full-scale, building-implemented green roofs, and no articles were found on the building technical performance of aged green roofs. These knowledge gaps indicate a major risk factor in green roof operation, as their performance and integrity over time has not been documented. This despite the fact that green roofs have been implemented and in operation worldwide for decades.

Green roofs are components of the building envelope that have become increasingly popular in urban contexts because other than providing numerous environmental benefits they are also capable of reducing building energy consumption, especially in summer. However, despite all these advantages, green roofs are still affected by some limitations. Specifically, there are some gaps affecting the energy modelling consisting in the absence of a proper database, information (growth stage, leaf area index, and coverage ratio) relative to the different green roof plant species, which technicians could use in case of lack of actual field data to perform energy analysis of buildings equipped with green roofs. These gaps concern also environmental and economic assessments of such technology. In fact, the currently available green roof LCA and LCC studies seem to underestimate the role of the substrate on the overall environmental impact and the role of the disposal phase on the life cycle cost of the green roof. In this chapter, all these aspects are addressed, and contributions to their solution, which arose from both experimental and modelling research, carried out by the authors are presented.
