“…The structural element is assumed to be lightly-loaded and its thickness is ruled by durability constraints, for conventional reinforced concrete, and ruled by bond requirements in TRC. Then, as in [ 14 ], thicknesses of 60 mm and 18 mm are considered for the conventional reinforced concrete and for the TRC solutions, respectively. For the sake of simplicity, the remaining dimensions of the element (width and length) are 1 m.…”

“…Savings up to 75% have been claimed by Curbach et al [ 13 ]. Laiblová et al [ 14 ], in a comparison between TRC and conventional reinforced concrete, through Life Cycle Assessment, have considered a volume reduction of 70%. They defend the idea that TRC has potential for use in sustainable construction, as well as the claim that, besides reducing production costs, TRC also brings savings in transportation costs as the elements are lighter.…”

Textile reinforced concrete (TRC) is an emerging construction material with interesting potential concerning sustainability, providing corrosion-free and lightweight solutions. Ordinarily, fiber bundles, impregnated with resin, are used. In this research the performance of reinforcement with unresin fibers is investigated. Control of cracking is considered the key performance factor and is assessed through tensile testing. However, economic and environmental aspects are addressed as well. Then, four different mixes/matrices were considered, without the addition of special/expensive admixtures. TRC ties were subject to direct tension tests, with load and deformation monitoring to assess the influence of mechanical reinforcement ratio on the cracking, failure and toughness of these composites, as well as of the matrix properties on the maximum load. It was observed that at a macro-level TRC behaves like conventional reinforced concrete, concerning crack control. Based on the maximum loads attained at the different composites, it was found that this particular TRC is economically viable. It is suggested that matrix workability may influence the maximum load.

“…Therefore, at this stage, it is infeasible to evaluate all LCA indexes in the integrated model. In this regard, we analyzed some building LCA cases, building materials LCA cases and some related studies and found that the indexes related to greenhouse gases, sulfur oxides, nitrogen oxides, photochemical oxidants, and resource consumption were concerned in the construction field [48][49][50][51]. Considering the limitations of actual conditions, at present, the selection of LCA indexes in the integrated model would focus on the environmental impact brought by the above substances.…”

The Impact Assessment of Campus Buildings Based on a Life Cycle Assessment–Life Cycle Cost Integrated Model

et al. 2019

The development of higher education has led to an increasing demand for campus buildings. To promote the sustainable development of campus buildings, this paper combines social willingness-to-pay (WTP) with the analytic hierarchy process (AHP) based on the characteristics of Chinese campus buildings to establish a life cycle assessment–life cycle cost (LCA–LCC) integrated model. Based on this model, this paper analyses the teaching building at a university in North China. The results show that the environmental impacts and economic costs are largest in the operation phase of the life cycle, mainly because of the use of electric energy. The environmental impacts and economic costs during the construction phase mainly come from the building material production process (BMPP); in this process, steel is the main source. Throughout the life cycle, abiotic depletion-fossil fuel potential (ADP fossil) and global warming potential (GWP) are the most prominent indexes. Further analysis shows that these two indexes should be the emphases of similar building assessments in the near future. Finally, this study offers suggestions for the proposed buildings and existing buildings based on the prominent problems found in the case study, with the aim to provide reference for the design, construction, and operation management of similar buildings.

“…That research project further illustrated that an optimized design, for example, multifunctional vacuum‐insulated façade element made of GFRC, reduced the overall impact more than a pure material substitution (−74 kg CO 2 ‐eq/m 2 ). More recent, Laiblová et al 36 also studied an experimental façade with application of cradle‐to‐grave LCA. Again, CCC showed on average lower environmental impacts as compared with SRC.…”

The narrative sustainable building is core message of European politics. Strategies discussed in this regard concern above all material minimization by using new more efficient manufacturing technologies, new form finding approaches for load-bearing structures or new high-performance materials. The goal of the research project V2.10, funded by the German Federal Ministry of Education and Research, refers to the latter by assessing the sustainability potential of building components made of innovative textile reinforced concrete. We conceptualized a life cycle sustainability assessment framework and applied it to variants of sandwich wall systems made of carbon concrete composites and steel-reinforced concrete. Results indicate hotspots in technology and material choices that could be addressed by circular strategies, for example, refuse, reduce or recycling. Overall, one design variant made of carbon concrete composites is the best performing with respect to all dimensions of sustainability.

These approaches are consistent with the international ambitions of achieving Sustainable Development Goals #9 to #13. 11 The European Construction Products Regulation already requests, among others, to consider reuse and recyclability of the construction
