“…In many of the studies, Ecoinvent was the most frequently utilized life cycle inventory library [4][5][6]13,15,29,30,51,52] The Athena library was utilized in four articles [2,8,15,42,49,50]. Some researchers employed an environmental product declaration (EPD) for impact evaluation, while others utilized an Australian database for their study [7,14].…”

“…According to Table 5, although different impact assessment methodologies have varied mid-point impact categories, only a few researchers studied a diverse range of midpoint impacts [3]. Most studies focused on carbon emissions, followed by eutrophication, acidification, embodied energy and primary energy, and abiotic depletion [3,5,[12][13][14]47,49,52]. Some articles discussed endpoint impacts such as human health, ecosystem quality, climate change, and resource availability [2,7,40,54].…”

Life Cycle Environmental Sustainability and Energy Assessment of Timber Wall Construction: A Comprehensive Overview

This article presents a comprehensive overview of the life cycle environmental and energy assessment for all residential and commercial constructions made of timber walls, globally. The study was carried out based on a systematic literature analysis conducted on the Scopus database. A total of 66 research articles were relevant to timber wall design. Among these, the residential construction sector received more attention than the commercial sector, while the low-rise construction (1–2 stories) gained more attention than high-rise construction (>5 stories). Most of these studies were conducted in Canada, Europe, Malaysia, and the USA. In addition, the end-of-life phase received limited attention compared to upstream phases in most of the studies. We compared all environmental and energy-based life cycle impacts that used “m2” as the functional unit; this group represented 21 research articles. Global warming potential was understandably the most studied life cycle environmental impact category followed by acidification, eutrophication, embodied energy, photochemical oxidation, and abiotic depletion. In terms of global warming impact, the external walls of low-rise buildings emit 18 to 702 kg CO2 kg eq./m2, while the internal walls of the same emit 11 kg CO2 kg eq./m2. In turn, the walls of high-rise buildings carry 114.3 to 227.3 kg CO2 kg eq./m2 in terms of global warming impact. The review highlights variations in timber wall designs and the environmental impact of these variations, together with different system boundaries and varying building lifetimes, as covered in various articles. Finally, a few recommendations have been offered at the end of the article for future researchers of this domain.

“…Two further LCA studies of wall elements that put timber options well ahead of the alternatives are Lupíšek et al (2017) and Pomponi and D'Amico (2017). From a cradle-to-gate (A1-A3) perspective, the former study compared a wood-based curtain wall panel with an aluminium one, and the latter study compared a timber-based double skin façade and a traditional envelope solution assessed over its whole lifecycle including the operational stage B6 and module D as an option.…”

“…Consequentially, a joint analysis of structural mass and carbon emissions could have significant benefits in terms of environmental impact reduction [14,15]. Additionally, it has been shown that, 1 Embodied carbon is here defined as the sum of CO2e emissions related to all processes and activities that occur throughout a building's life, from resource extraction and product manufacturing, transportation, construction and installation, through to maintenance and end of life activities.…”

Building structures often represent the element with the largest mass in a building project, with significant effects on the buildings life cycle environmental impacts. Amongst structural materials, steel is characterised by its suitability to a large number of structures as well as a highly pollutant supply chain. Therefore, even a small reduction of the amount of steel currently used in building structures, would undoubtedly be beneficial towards the mitigation of environmental impacts. This paper presents a computational tool that aims to help practitioners to design material-efficient structures for multi-storey buildings frames. The tool is based on an optimisation framework, which -given a small set of input parameters defining the overall frame geometry and the system of loadings-seeks for optimised cross-sections for each structural member, based on a finite set of commercially available section profiles. Results are fully compliant with British and European
