“…However, already for London, only one of the CTB designs is better than the conventional UK wall, while without considering transportation there are 15 preferable designs in the UK (see Figure ). This shows that including LC stage A4 is important when preparing a new product for future market entry (Göswein et al., ).…”

The built environment is the largest single emitter of CO2 and an important consumer of energy. Much research has gone into the improved efficiency of building operation and construction products. Life Cycle Assessment (LCA) is commonly used to assess existing buildings or building products. Classic LCA, however, is not suited for evaluating the environmental performance of developing technologies. A new approach, anticipatory LCA (a‐LCA), promises various advantages and can be used as a design constraint during the product development stage. It helps overcome four challenges: (i) data availability, (ii) stakeholder inclusion, (iii) risk assessment, and (iv) multi‐criteria problems. This article's contribution to the line of research is twofold: first, it adapts the a‐LCA approach for construction‐specific purposes in theoretical terms for the four challenges. Second, it applies the method to an innovative prefabricated modular envelope system, the CleanTechBlock (CTB), focusing on challenge (i). Thirty‐six CTB designs are tested and compared to conventional walls. Inclusion of technology foresight is achieved through structured scenario analysis. Moreover, challenge (iv) is tackled through the analysis of different environmental impact categories, transport‐related impacts, and thickness of the wall assemblies of the CTB. The case study results show that optimized material choice and product design is needed to reach the lowest environmental impact. Methodological findings highlight the importance of context‐specific solutions and the need for benchmarking new products.

“…Therefore, a sensitive analysis is recommended before considering the transportation scenario. For example, the method developed by study of Göswein et al [105] can be used to obtain a sensitive analysis. According to ELCD core database V3.0, two main types of lorries (medium sized lorry transport, low impact, maximum capacity of 17.3 tonnes; articulated lorry transport: high impact, maximum capacity of 27 tonnes) are used to transport raw materials to concrete plant (Table 4).…”

The aim of this critical review is to show the applicability of recycled fine aggregates (RFA) in concrete regarding technical performance, environmental impact, energy consumption and cost. It is not possible to judge the performance of concrete by considering one dimension. Thus, this study focussed on the fresh and hardened (e.g., mechanical and durability) properties and environmental and economic life cycle assessment of concrete. Most literature investigated showed that any addition of recycled fine aggregates from construction and demolition waste as a replacement for natural fine aggregates proves detrimental to the functional properties (quality) of the resulting concrete. However, the incorporation of recycled fine aggregates in concrete was proven to enhance the environmental and economic performance. In this study, an extensive literature review based multi criteria decision making analysis framework was made to evaluate the effect of RFA on functional, environmental, and economic parameters of concrete. The results show that sustainability of RFA based concrete is very sensitive to transportation distances. Several scenarios for the transportation distances of natural and recycled fine aggregates and their results show that only if the transportation distance of the natural aggregates is more than double that of RFA, e the RFA based concrete alternatives would be considered as more sustainable.

“…Increased construction activity is exacerbating raw materials scarcity and emissions associated with the transportation and manufacturing of building materials [37]. Industrial by-products and waste materials like waste foundry sand [38,39], ground granulated blast furnace slag [40,41], steel slag [42,43], imperial smelting furnace slag [44], copper slag [45,46], bottom ash [47,48], class F type fly ash [48,49], silica fumes [50], palm oil clinker [51], rice husk ash [52,53], bagasse [54,55] and composites [56] have been found to improve buildings' structural and environmental performance when used instead of fine aggregates.…”

A Review of Residential Buildings’ Sustainability Performance Using a Life Cycle Assessment Approach

Achieving sustainable buildings is a challenging task. Building sustainability involves "green building" design and construction, taking account of both environmental elements and economic benefits, along with social obligations to the society we live in. This article aims to critically review and analyse studies of the building and construction industry that deal with aspects of sustainability, including environmental life cycle assessment, life cycle costing, social life cycle assessment and cleaner production strategies, and to examine the research gaps in order to generate recommendations for further research. About 807 refereed research articles on residential buildings published over the last 10 years (2009-2019), were downloaded, having been searched from online databases (including Scopus, Web of Science, ScienceDirect and Compendex) using keywords. Building materials, embodied energy and operating energy were found to contribute chiefly to the environmental and socioeconomic objectives of the construction industry. Many studies covered only the life cycle tools (such as environmental life cycle assessment, life cycle costing, and social lifecycle assessment) used in the sustainability assessment process. The "carbon footprint" concept is the most commonly used indicator in building sustainability assessments, underlining the urgent need to deploy more diverse environmental impact categories in order to avoid trade-offs among environmental, social and economic objectives. The social life cycle assessment tool needs a methodological breakthrough to improve its application in the building industry. In most of the studies, only an approximate evaluation of buildings' service life is the main consideration in life cycle assessments, while the important factor of the quality of the materials used in buildings is often neglected. However, a methodological approach to estimate the service life of structures that considers the durability of different building components would provide a more realistic life cycle assessment. Hence it would be judicious to address the thematic and methodological gaps identified in this paper, thereby optimising the understanding and communication of life cycle outcomes in building sustainability.
