“…The figure also indicates that the operation and maintenance stage is the key link in GGE reduction for large-scale public buildings, which is consistent with previous studies [34,40,45,46]. Managers can adopt measures, such as using more energy-efficient facilities and improving users' behavior to further improve the sustainability and environmental performance of a building.…”

“…It can be seen that the amount of GGE generated in summer is higher than the other three seasons because more energy is consumed on air conditioning for cooling the high temperature. The result is different with the figure for buildings located in regions with a hot summer and cold winter like Nanjing or Hefei [34,40]. The monthly GGE of buildings during the operation and maintenance stage in these regions usually has two peak values.…”

Exiting green building assessment standards sometimes cannot work well for large-scale public buildings due to insufficient attention to the operation and maintenance stage. This paper combines the theory of life cycle assessment (LCA) and building information modeling (BIM) technology, thereby proposing a green building assessment method by calculating the greenhouse gas emissions (GGE) of buildings from cradle to grave. Life cycle GGE (LCGGE) can be divided into three parts, including the materialization stage, the operation and maintenance stage, and the demolition stage. Two pieces of BIM software (Revit and Designbuilder) are applied in this study. A museum in Guangdong, China, with a hot summer and warm winter is selected for a case study. The results show that BIM can provide a rich source of needed engineering information for LCA. In addition, the operation and maintenance stage plays the most important role in the GGE reduction of a building throughout the whole life cycle. This research contributes to the knowledge body concerning green buildings and sustainable construction. It helps to achieve the reduction of GGE over the whole life cycle of a building. This is pertinent to contractors, homebuyers, and governments who are constantly seeking ways to achieve a low-carbon economy.

“…Numerous tools and frameworks to improve the BIM-LCA workflow and interoperability have been developed to enable faster and better assessment as [49,[59][60][61] but are limited to data exchange and do not take into account the capacity of the designer to change the design and offer no design option to reduce the environmental impact. However, Wastiels, L. [58] takes also into account BIM-LCA to give real-time feedback on design decisions.…”

A BIM-Based Framework and Databank for Reusing Load-Bearing Structural Elements

et al. 2020

In a context of intense environmental pressure where the construction sector has the greatest impact on several indicators, the reuse of load-bearing elements is the most promising by avoiding the production of waste, preserving natural resources and reducing greenhouse gas emissions by decreasing embodied energy. This study proposes a methodology based on a chain of tools to enable structural engineers to anticipate future reuse. This methodology describes the design of reversible assemblies, the addition of complementary information in the building information modeling (BIM), reinforced traceability, and the development of a material bank. At the same time, controlling the environmental impacts of reuse is planned by carrying out a life cycle assessment (LCA) at all stages of the project. Two scenarios for reuse design are applied with the toolchain proposed. A. "design from a stock" scenario, which leads to 100% of elements being reused, using only elements from stock. B. "design with a stock" scenario, which seeks to integrate as many reused elements available in the stock as possible. The case study of a high-rise building deconstructed to rebuild a medium-rise building demonstrated that the developed toolchain allowed the inclusion of all reuse elements in a new structural calculation model. Sustainability 2020, 12, 3147 2 of 24 the largest exploiters of natural resources [8], accounting for between 40% of the total raw materials consumption [9] and 50% [10].This growing development has repercussions on the emission of GHGs, among other indicators. In France, the construction and building industry is the leading emitter of GHGs [11], i.e., 33% of total GHGs. Several studies confirm this number worldwide [6,12,13]. Kumar Dixit et al. [8] define the embodied energy (EE) and embodied carbon (EC). EE during the construction phase is the amount of energy used for the extraction of raw materials, the production and transport of building components as well as the building construction and end-of-life (EOL). Moreover, EC refers to the associated GHG emissions [3]; the operating energy during the operation phase as energy consumption and associated operational carbon emissions during the use phase of buildings (heating, cooling, etc.). The average value of EE is 50% of the total primary energy demand [14]. The share of operational energy seems to decrease recently (even disappearing in passive or zero energy buildings) with technical progress and, therefore, the share of EE increases [15].Another impact of the construction sector is due to waste generation [5,16]. Most of the literature focuses on waste management, which shows a great interest in reducing the construction and demolition waste (CDW) generated by the construction sector as it represents around 40% of the waste produced [17]. Cai et al. [18] and Lismont et al. [19] explained that in Europe, about 25-30% of the waste result from the building sector amounting to 870 million tons annually and Brütting et al. [3] estimated this share at more than a third ...

“…The relevance of carbon emissions and low-emission window films on energy spending was studied in [22] and applied to an existing UK hotel building. In [23], a methodology was built for the investigation of carbon emissions in a hospital building, which allowed the generation of an information model and an evaluation of its life cycle. In [24], an optimization of reinforced concrete columns was optimized considering several environmental impact assessment parameters.…”

Black Hole Algorithm for Sustainable Design of Counterfort Retaining Walls

The optimization of the cost and CO 2 emissions in earth-retaining walls is of relevance, since these structures are often used in civil engineering. The optimization of costs is essential for the competitiveness of the construction company, and the optimization of emissions is relevant in the environmental impact of construction. To address the optimization, black hole metaheuristics were used, along with a discretization mechanism based on min–max normalization. The stability of the algorithm was evaluated with respect to the solutions obtained; the steel and concrete values obtained in both optimizations were analyzed. Additionally, the geometric variables of the structure were compared. Finally, the results obtained were compared with another algorithm that solved the problem. The results show that there is a trade-off between the use of steel and concrete. The solutions that minimize CO 2 emissions prefer the use of concrete instead of those that optimize the cost. On the other hand, when comparing the geometric variables, it is seen that most remain similar in both optimizations except for the distance between buttresses. When comparing with another algorithm, the results show a good performance in optimization using the black hole algorithm.
