“…Due to the unavailability of the data for staircase material quantities, they were excluded from the LCA. The quantity of floor coverings (e.g., floor tiles or carpet) and paint were not included in this study because they were assumed to be identical and did not result in any significant changes in terms of impacts [49]. Both houses' annual electricity consumption and water demand scenarios were assumed to be steady over their lifetimes.…”

“…Vitale et al compared two different building material types (cold-formed steel and reinforced concrete) in residential buildings with a cradle-to-grave system boundary and a building lifespan of 50 years. The study concluded that cold-formed steel (CFS) structures outperform concrete in terms of environmental performance (24% GWP) [49]. Hawkins et al contrasted the embodied carbon of concrete, steel, and timber building structures.…”

“…They discovered that the service life of a building and its components had a direct link with the environmental performance, namely the replacement intervals, and that it was recognised as the third major contributing factor to the overall environmental effects after use and pre-use [55]. Referring to previous building LCA studies [46][47][48][49][50][51][52][53], it seemed that the lifespan of buildings has ranged between 50 and 100 years, resulting in varied assessment outcomes. The condition leads to a knowledge gap in implementing environmental assessment of building products and results in varied assessment results, primarily caused by the various scopes of assessment and the unidentical design of the buildings.…”

A Comparative Study on the Life Cycle Assessment of New Zealand Residential Buildings

et al. 2022

In New Zealand, housing is typically low density, with light timber framing being the dominant form of construction with more than 90% of the market. From 2020, as a result of the global pandemic, there was a shortage of timber in New Zealand, resulting in increased popularity for light steel framing, the main alternative to timber for housing. At the same time, the New Zealand government is committed to sustainability practises through legislation and frameworks, such as the reduction of whole-of-life carbon emissions for the building industry. New Zealand recently announced reducing its net greenhouse gas emissions by 50% within 2030. Life cycle assessment (LCA) is a technique for assessing the environmental aspects associated with a product over its life cycle. Despite the popularity of LCA in the construction industry of New Zealand, prior research results seem varied. There is no unified NZ context database to perform an LCA for buildings. Therefore, in this paper, a comprehensive study using LCA was conducted to quantify and compare the quantity of carbon emissions from two commonly designed houses in the Auckland region, one built from light timber and the other from light steel, both designed for a lifespan of 90 years. The cradle-to-cradle system boundary was used for the LCA. From the results of this study, it was found that the light steel house had 12.3% more carbon in total (including embodied and operational carbons) when compared to the light timber house, of which the manufacturing of two houses had a difference of 50.4% in terms of carbon emissions. However, when the end-of-life (EOL) analysis was included, it was found that the extra carbon could be offset due to the steel’s recyclability, reducing the amount of embodied carbon in the manufacturing process. Therefore, there was no significant difference in carbon emissions between the light steel and the light timber building, with the difference being only 12.3%.

“…It is very important to note that a careful acquisition of high-quality primary data is essential to reduce the uncertainties of LCA results (Vitale et al 2018, Moncaster et al 2018. This is extremely important when the intent is to capture the environmental impact of a construction system like the CFS that is not as spread as more traditional construction systems such reinforced concrete or masonry buildings that are familiar to a large part of people across Italy and Europe (Shares et al 2017).…”

“…With the scarcity and rising cost of timber resources as well as the increasing demands for environmental protection, this type of structure has been widely used as a substitute for timber structures in many developed countries and regions such as the United States, Japan, and Australia. CFS framed wall structures offer a multitude of advantages; for example, they are lightweight, have high strength, high construction efficiency, elegant structural form, and a high degree of industrialization, use less energy, and are environmentally friendly [1]. Wind is a common natural hazard that impacts high-rise structures, long-span structures, and lightweight low-rise structures, causing various degrees of structural damage or even collapse.…”

This paper presents a comprehensive assessment method of the fragility of low-rise cold-formed steel (CFS) framed wall structures subjected to wind hazards considering the fragility of both the main structure and the cladding system. The effects of wind directions on the fragility of CFS framed wall structures were also studied. For the main structure, the fragility curve is established using the maximum interstory drift ratio (ISDRmax) as the performance index for assessing the wind fragility of the structure. For the cladding system, the probabilistic models of the wind load and the cladding component resistance are established based on Monte Carlo simulation, and then methods for the fragility assessment of single cladding components and the cladding system under wind hazards considering the influence of the number and arrangement of the cladding components are proposed. The results indicated that, under strong wind, the cladding system may be damaged before the required wind resistance capacity of the main structure is exhausted. In particular, the roof sheathing is the most prone to damage, followed by the stud wall. That is, before the main structure is severely damaged or collapses, the cladding systems may be severely damaged, rendering the structure unusable. Therefore, the comprehensive assessment of the fragility of this type of structure subjected to wind hazard considering the fragility of both the main structure and the cladding system is more accurate. This study is of great significance for the improvement of the wind resistance performance of CFS structures and the popularization of this type of structure.
