“…The scope definition needs an explicit description of the subject to be studied (e.g., an engineered wood product), functional unit, system boundary, data requirements, impact categories selected, and other scope definition items. , Previous LCAs of engineered wood products commonly select product-level units as their functional units (e.g., 1 m 3 of wood product, 1000 board feet of wood product). Among those, 1 m 3 of engineered wood products is the most adopted in previous literature. − Other product-level functional units are related to specific constructional applications (e.g., 1 m 2 of the roof, 30 m 2 of surface decking) to compare with traditional building materials (e.g., steel). − For example, Petersen and Solberg used 1 m 2 roof as the functional unit to compare the life-cycle energy consumption and greenhouse gas (GHG) emissions of glulam and steel . Besides, stand-level functional units (e.g., 1 ha forest land) can be used to incorporate the effects of forest management strategies and forest yield into the LCA of wood products …”

The building sector, including building operations and materials, was responsible for the emission of ∼11.9 gigatons of global energy-related CO2 in 2020, accounting for 37% of the total CO2 emissions, the largest share among different sectors. Lowering the carbon footprint of buildings requires the development of carbon-storage materials as well as novel designs that could enable multifunctional components to achieve widespread applications. Wood is one of the most abundant biomaterials on Earth and has been used for construction historically. Recent research breakthroughs on advanced engineered wood products epitomize this material’s tremendous yet largely untapped potential for addressing global sustainability challenges. In this review, we explore recent developments in chemically modified wood that will produce a new generation of engineered wood products for building applications. Traditionally, engineered wood products have primarily had a structural purpose, but this review broadens the classification to encompass more aspects of building performance. We begin by providing multiscale design principles of wood products from a computational point of view, followed by discussion of the chemical modifications and structural engineering methods used to modify wood in terms of its mechanical, thermal, optical, and energy-related performance. Additionally, we explore life cycle assessment and techno-economic analysis tools for guiding future research toward environmentally friendly and economically feasible directions for engineered wood products. Finally, this review highlights the current challenges and perspectives on future directions in this research field. By leveraging these new wood-based technologies and analysis tools for the fabrication of carbon-storage materials, it is possible to design sustainable and carbon-negative buildings, which could have a significant impact on mitigating climate change.

“…Some studies were published on how to separate attached cement mortar from the aggregate surface from waste concrete (e.g., via heat treatment and abrasion or separation by microwave heating) [25,26]. The LCA method is one possible way to compare the environmental impacts of concrete structural elements [27].…”

The main goal of this study was to compare two use cycles of natural aggregate concrete and recycled aggregate concrete, which is another way to compare the environmental impacts of recycled materials. A series of concrete mixtures with various replacement ratios of primary resources with recycled ones were prepared for this study. The mechanical properties of concrete mixtures were examined and were used for the design of structural elements in the same utilized properties. The two use cycles of a structural element were compared using life cycle assessment (LCA). In the first use cycle, the LCA of the structural element containing only primary raw materials was assessed. In the second use cycle, the LCA of a structural element in which primary materials were partially replaced by recycled ones was assessed. The obtained results confirm the potential use of high-quality recycled aggregate originating from local sources in some applications in building structures. Furthermore, the environmental assessment indicates the benefits of using recycled materials, such as environmental savings, especially the reduction of primary resource use, embodied energy, and embodied emissions, as well as reduction of the pressure on landfill sites.

“…LCA: In order to make the LCI, data collection and quantification of energy input-output were required; as well as the affectation made by the analyzed systems. The database used for the LCI was Ecoinvent V3.0 [28], which is of recognized use in various European investigations due to its representativeness, evaluation transparency and accuracy of the data [9,13,[29][30][31]. The Swiss Federal Offices and the ETH Zurich developed this database, which has a global level, and contains a wide spectrum of activities and systems; its selection for this research is because the information available in the Spanish field is limited or null.…”

Numerous studies have been done with the purpose of identify and try to reduce the impact generated by the construction industry, mainly focused on the use stage in the search to increase the energy efficiency. However, as these stage has been improved and the impact produced has been reduced, it has become evident the need to focus the research on the elements and life cycle stages that follow on the affectation scale. Therefore, the present research analyzes the importance of the embodied energy and the affectation generated by the materials with a LCA perspective, comparing one square meter of three different systems used as interior partition walls: hollow clay brick (HB), hollow concrete block (CB) and gypsum board (GB). The analyzed stages are from production of the materials to the building construction (stages A1–A5), using the Eco-invent database with the LCA manager software. The results of the analysis indicate the values of the environmental affectations and the consumptions made by each element during the analyzed stages. The comparison allowed to find that the constructive solution with mayor environmental affectation in the analyzed categories is the GB wall, and that is mostly done in the production stage (A1–A3).
