“…Other studies vary the discount rates used to simulate the impact of changes-for example, 0%, 5%, and 10%. More unusual rates include 12% [76], 7.6% [120], 4.17% [167], and between 3% and 6% [181].…”

“…The notion of the "3 Ps": planet, people, and profit also goes along with this interpretation of sustainability. The main idea behind this three-dimensional concept is not to split up sustainability but to show that it is "a state where there exists a perfect balance between social, economic, and environmental processes" [181].…”

“…On the midpoint level, CML is most popular, followed by ReCiPe and the more recent ILCD method. Furthermore IMPACT 2002+ [183], TRACI [181], IWM-2 [172], and the Athena Impact Estimator [169,187] are used at least once. This reflects, on the one hand, the European focus of LCA studies (Asian authors also prefer the European methods) and, on the other hand, the fact that it takes several years for new LCIA method packages to be applied in publications.…”

“…In some studies, it is not clear what is done [121,125,202,203], but it is obvious that something is done. One study [126] discusses a ranking approach as well as normalization and Gencturk, et al [181] normalize only the environmental indicators and leave the other indicators in their original state. In addition, several normalization approaches are applied in some studies.…”

“…Of the analyzed case studies, 56% decided to aggregate their individual indicators to one result. Some studies aggregate only parts of their results, e.g., within one sustainability dimension [181,184,207]. Those numbers show that not all studies aggregate their normalized or ranked single results [118][119][120]199].…”

Review of Sustainability Assessment Approaches Based on Life Cycles

Many different approaches have been developed to quantify and evaluate sustainability. Here a review is performed on sustainability assessment based on Life Cycle Thinking, which mostly means Life Cycle Sustainability Assessment (LCSA). Until the end of 2018, 258 publications can be found, from which 146 include a case study. The highest number of publications appeared between 2016 and 2018 and, compared to the years before 2016, the number of authors has increased. However, in recent years the focus has been more on case studies than on methodological aspects of LCSA. The presented holistic approaches for LCSA are either too broad or too narrow for scientific guidance. Therefore, many questions concerning LCSA are still open, e.g., regarding definition of sustainability dimensions and the desire or need for multi-criteria decision-analysis. An underlying problem is the lack of discussion about sustainability concepts. The momentum in the community to perform case studies for LCSA should be used to also develop more guiding principles.

Summary The use of energy dissipaters for creation of earthquake‐resilient buildings has been paid more and more attention in recent years, and some newly developed structural fuses or dampers have been proposed to be employed in rocking and seesaw buildings. In this study, a new type of yielding‐based dampers, called curved‐yielding‐plates energy dissipater (CYPED), is introduced. CYPEDs are installed at the bottom of rocking or seesaw building's circumferential columns at the lowest story and have hysteretic behavior in their deformation occurring in vertical direction. The initial curvature of the yielding plates prevents them from buckling and gives the device a smooth force–deformation behavior. First, by performing a set of cyclic tests on three specimens of CYPED, their hysteretic force–displacement behavior was investigated. Then, to show the efficiency of this energy dissipating device in reducing the seismic response of buildings, they were employed numerically as multilinear plastic springs in the computer models of a sample seesaw steel building, and a series of nonlinear time history analysis (NLTHA) were performed on both seesaw building and its conventional counterpart. Results of NLTHA show that the proposed seesaw structural system equipped with appropriate CYPEDs not only gives the building a longer natural period, leading to lower seismic demand, but also leads to remarkable energy dissipation capacity in the building structure at base level and, therefore, keeping the seismic drifts in elastic range in all stories of the building. In this way, the building structure does not need any major repair work, even after a large earthquake, while the conventional building suffers from heavy damage and is not usable after the earthquake.
