“…Based on experiments, theoretical analyses, and simulation software such as Energy Plus 8.2.0, PKPM V3.1, and DeST3.0, the insulation [27][28][29], air tightness [30][31][32], and shading performance [33][34][35] on building energy consumption of building curtain wall have been extensively investigated. The results underscore the pivotal role of curtain walls in building energy consumption.…”

Curtain wall systems stand out as a pivotal domain within the construction sector’s endeavors towards energy efficiency and carbon mitigation. To refine the evaluation framework for carbon emissions within this industry, this paper explores the calculation and assessment method for building curtain walls. The article first reviews the current research status regarding carbon emissions from materials and the impact of curtain walls on buildings in the operational stage. Based on lifecycle theory, the carbon emissions from building curtain walls are divided into six stages: material acquisition, processing and production, installation and construction, transportation, use and maintenance, and dismantling. On this basis, this paper proposes a method for calculating carbon emissions from building curtain walls. Following that, a case study is conducted using a specific glass curtain wall project for illustrative analysis. The results indicate that the carbon emissions from the material acquisition stage constitute approximately 90% of the total, serving as the primary source of carbon emissions for glass curtain walls. Furthermore, the scientific application of photovoltaics can significantly reduce the carbon emission levels of building curtain walls. Finally, an analysis was conducted on the current issues existing in the evaluation of carbon emissions.

“…The BIM approach can reduce the life cycle cost by up to 27%, optimizing the HVAC efficiency; the optimal design strategy can yield savings of up to 13% in the life cycle energy and 12% in the life cycle cost compared to the regular design approach. Using external thermal insulation can substantially decrease the life cycle cost; the heating and cooling comprise about 17-73% of the total energy consumed; and compared to curtain walls, rockwool and polystyrene walls can reduce the energy consumption by 17% and 12.7%, respectively [67].…”

Purpose: This paper conducts a review of the different research carried out recently on the behavior of non-structural elements (NSEs) and the life cycle assessment (LCA) during an earthquake. It focuses on the study conducted recently and identifies the gaps and way forward for future work. Methods: A systematic literature review was carried out among the different research works. The proposed literature review includes (i) identifying the recent research work using the keywords in available search engines, (ii) studying different research papers and selecting the relevant papers only, and (iii) vulnerability and LCA for NSEs and their research gaps. Results and discussions: A summary is given of the importance and type of NSEs under earthquakes, including life cycle cost assessment for NSE, environment life cycle assessment (ELCA) and social life cycle assessment (SLCA) for different facilities and the embodied energies. Conclusions and recommendations: This paper highlights the problems associated with NSEs. For new constructions, modifications to improve the performance of NSEs, particularly infill walls are under research, however for old buildings, their location is also vital. Numerical methods are performed using different tools available; however, implementation is a big challenge to economize the life cycle and its impact on the community.

“…The building stock inventory can be refined by integrating BIM with life cycle costing in a sophisticated way rather than manual approach [94]. The BIM approach can reduce the Life cycle cost by up to 27% optimizing the HVAC efficiency; optimal design strategy can yield savings of up to 13% in Life cycle energy and 12% in Life cycle cost compared to the regular design approach; using external thermal insulation can substantially decrease the Life cycle cost; the heating and cooling weighs about 17%-73% of the total energy consumed; compared to curtain wall, Rockwool and polystyrene wall can reduce the energy consumption by 17% and 12.7% respectively [95].…”

The response of building elements during earthquakes has been an area of concern for different researchers around the world. The NSEs are the first elements to attain failure, the buildings after damages in safety priority are classified as in “Life Safety” mode, but in reality, they are in “Collapse Safety” mode and the occupants inside the buildings are in a state of “Non-Life Safety” as a result of falling of the hazardous NSE’s like cladding's, partitions, hanging objects. In addition to the Life Cycle Cost Assessment (LCCA), the Social Life Cycle Assessment (SLCA) is overlooked by the majority of the researchers, the community must be prepared to respond to an event more efficiently without any major casualties or loss of life. It is expected that by the end of 2050, almost double the construction will take place, the embodied energy during the pre-construction, post-construction and demolition generates a lot of CO2s into the environment, hence sustainability should be given due importance, helping in the achievement of Sustainable Developmental Goals (SDGs).
