“…Ben-Alon et al [35] suggested utilizing an alternative wall construction (cob earthen) for conventional materials (concrete masonry and wood wall) and identified cob construction's environmental performance from a life cycle perspective. Assessing different wall systems based on their Global Warming Potential and Fossil Fuel Consumption using LCA has been studied by Dekkiche et al [36] in a certified LEED gold building. Vilcekova et al [13] analyzed different building materials for exterior walls in terms of embodied energy and embodied carbon.…”

The need to enhance the performance of building façades and mitigate adverse environmental impacts has promoted the hypothesis of integrating green materials towards sustainable buildings. Façade designers tend to select building materials based on their green characteristics (origin) or green performance; however, this study highlights the importance of integrating both into the decision process. The main objective is to develop a new assessment process for selecting green building façade materials based on green performance and green originality. Furthermore, the evaluation framework considers four green building rating systems as a reference to allocate credits for the relevant criteria. Applying the proposed criteria in this study helps maximize the points for accreditation when incorporating green building materials in building façades. Moreover, the Analytic Hierarchy Process (AHP) is used to assign the proposed criteria’s weighting importance based on the four rating systems’ average points. After that, performing sensitivity analysis to identify each criterion’s influence is conducted. The study concluded that involving minimum levels of adverse impacts is the preferable criteria regarding the green origin concept. As for the green performance, promoting the performance of indoor air quality is the most favorable selection criteria.

“…The main advantage of integrating LCA with BSAT is in helping to create a robust quantitative assessment method [138]. Some studies explore ways to integrate LCA into BSAT [149]. However, Ismaeel [150] pointed out that LCA is only partially integrated by BSAT and is not reflected at the overall-system level.…”

With the rapid development of materials science and construction technology, the concept of sustainable building (SB) and the Building Sustainability Assessment Tool (BSAT) have also evolved and developed. Understanding the development of BSAT and SB is of great significance to the sustainable development of the construction industry. This research used the bibliometric method to analyze the development and evolution in the relevant literature on SB and BSAT from 1990 to 2021, and the correlations and differences between them were investigated. We found that there are many common trends in the development of research efforts in SB and BSAT: (1) they focused solely on the environment, in the early days, and only later considered economic and social impacts; (2) the scales with which they are concerned continue to expand, from individual buildings to communities and even cities; (3) key areas, such as energy, materials, resources, indoor environmental quality, high-tech applications, adaptability, and concern for people are being given more attention by both SB and BSAT. On the other hand, the difference between them is that SB research focuses on more macro aspects, such as policy, culture, climate change, while BSAT research is more concerned with micro aspects, such as its system of tools. Furthermore, some current research gaps in the BSAT field are identified, clarifying its future research directions. By linking the evolution of the SB concept and the development of the BSAT research field, this review provides a new and valuable perspective for the sustainable assessment of the construction industry, which, itself, is conducive to the sustainable transformation of this industry, which could contribute greatly to the mitigation of global climate change.

“…The LEED rating system is a voluntary, consensus-based, mark driven rating system based on existing proven technology [25][26][27][28] [25]. LEED is a performance-based system where credits are earned for satisfying criteria designed to address specific environmental impacts inherent in the design, construction, and operation and maintenance of buildings.…”

Abstract. This paper applied the densified mixture design algorithm(DMDA) method by incorporating ternary pozzolans (fly ash, slag and silica fume; mix I and mix II) to design high strength concrete (HSC) mixtures with w/cm ratios from 0.24 to 0.30. Concrete without pozzolans was used as a control group (mix III, w/c from 0.24 to 0.30), and silica fume (5%) was added as a substitute for part of the cement and set as mix IV. Experiments performed compressive strength, four-point resistance meter to measure the conductivity, and rapid chloride ion penetrability tests (ASTM C1202) were assessed the anti-corrosion. The life cycle inventory of LEED suggested by the PCA indicated the green options for cementitious materials. Results showed that mix I and II indicated cement used, CO 2 reduction, raw materials and energy consumption all decreased more 50% than mix III, and mix IV was 5% less. The compressive strength and anti-corrosion levels showed that mix I and II were better than mix III and IV, and with ternary pozzolans could enhance the long-term durability (92 days) due to a resistivity greater 20 Kȍ-cm and a charge passed lower than 2000 Coulombs. HSC with an appropriate design could reduce the carbon footprint and improve the durability.
