“…Among the scientific gaps presented by the authors, the need for studies that address the use of CLT in buildings located in regions with a temperate and tropical climate stands out, that is, regions without considerable super-heating requirements, to analyze the energy consumption of cooling during the operational stage of the life cycle, among other implications of the use of the material in these regions (Dodoo, Gustavsson, Sathre, 2014a;Dong et al, 2019;Vidal, Sánchez-Pantoja, Martínez, 2019).…”

Cross Laminated Timber (CLT) is an engineered wood material that has been used in civil construction in structural functions previously reserved for materials such as steel or concrete. As it is a renewable material and promotes carbon sequestration, its use in civil construction is linked to mitigating global warming promoted by the industry. However, the increase in demand for this material raises questions about sustainability and what the environmental burden would be resulting from its mass production. Life Cycle Assessment (LCA) is an environmental management tool that can analyze this product chain as it maps and quantifies emissions and resource consumption from the production process, providing support for the calculation and analysis of environmental impacts. The goal of this study was to observe how the most recent research has been developed methodologically in terms of scope and what are the main scientific gaps presented in LCA studies of CLT material throughout its life cycle. To this end, a systematic literature review was carried out based on the Systematic Search Flow (SSF) method by Ferenhof and Fernandes (2014). The review points out the growing interest of the scientific community in the environmental profile of the product and the scope definitions were mostly cradle-to-grave study boundaries; the most applied functional unit is m² of building; impact analysis focus on quantifying global warming potential, energy resource consumption and carbon sequestration. The studies point to the end of life and the accounting of the material's biogenic emissions as scientific gaps, as well as the lack of studies with Brazilian data.

“…In the category of housing buildings, in a study on a multifamily mass timber dwelling in the city of Granada, Spain, Vidal and colleagues [1] determined a quantity of 65 kg CO 2 eq/m 2 of floor area for module A5. Specifically, this metric resulted from the consumption of 1878 kWh of electricity and 9000 L of diesel during the building construction phase.…”

Today, the application of green materials in the building industry is the norm rather than the exception and reflects an attempt to mitigate the sector’s environmental impacts. Mass timber is growing rapidly in the construction field because of its long span, speed of installation, lightness and toughness, carbon sequestration capabilities, renewability, fire rating, acoustic isolation, and thermal resistance. Mass timber is close to overtaking steel and concrete as the preferred material. The endeavor of this research is to quantitatively assess the ability of this green material to leverage the abatement of carbon emissions. Life cycle assessment (LCA) is a leading method for assessing the environmental impacts of the building sector. The recently completed Adohi Hall mass timber building on the University of Arkansas campus was used as a case study in an investigation to quantify greenhouse gas (GHG) emissions throughout the construction phase only. The energy used in building operations is the most dominant source of emissions in the building industry and has galvanized research on increasing the efficiency of building operations, but reduced emissions have made the impacts of embodied carbon (EC) components more noticeable in the building life cycle. While most studies have focused on the manufacturing stage, only a few to date have focused on the construction process. Consequently, few data are available on the environmental impacts associated with the installation of mass timber as a new green material. The present study began with the quantification of the materials and an inventory of the equipment used for construction. Then, this study determined the EC associated with running the equipment for building construction. The GHG emissions resulting from the transportation of materials to the site were also quantified. Based on data collected from the construction site, the results of this study indicate that earthwork ranks first in carbon emissions, followed by mass timber installation and construction. In third place is ready-mix poured concrete and rebar installation, followed by Geopiers. A comparison of these results with those in the existing literature shows that the EC generally associated with the building construction phase has been underestimated to date. Furthermore, only emissions associated with the fuel usage of the main equipment were considered.

“…Given that it is possible to fabricate it using recycled materials, the waste generated is also reduced, nearly 60% in comparison to other traditional construction materials: reinforced concrete, ceramic, or metallic materials [34]. To this must be added the low effect of transport on the total impacts [35], as it is a product whose manufacture is widespread since it does not require high technology to produce it.…”

A Research Methodology for Mitigating Climate Change in the Restoration of Buildings: Rehabilitation Strategies and Low-Impact Prefabrication in the “El Rodezno” Water Mill

New environmental challenges, coupled with the fact that 80% of the residential buildings that will exist in Europe in the year 2050 have already been built, mean that rehabilitation and restoration must be prioritised over new buildings. Construction is one of the largest generators of CO2. Using prefabricated and industrialised products and systems can help to mitigate its harmful effects thanks to the greater control and environmental evaluation that can be carried out on these products from their manufacture until the end of their useful life (LCA). In the county of the Sierra de Cádiz (Andalusia, Spain), there are 85 water mills, many of which are derelict and in disuse, which, due to their location, size, and characteristics, are ideal for rehabilitation and restoration for residential use. Taking the “El Rodezno” mill as a case study, this paper proposes rehabilitation strategies using prefabricated industrialised elements that have a low environmental impact. The methodological discussion takes as its starting point the process of design and testing that Alvar Aalto applied in 1940 and from subsequent studies that have confirmed a research structure based on the project design and the built project with the appropriate field of study and confirmation of the applicable strategies and solutions. To this end, this article is written on the basis of the two main phases of Alvar Aalto’s method, using the same terms that the Danish architect defined: Scientific Observation, for the study of preceding works and projects in light prefabrication and for the analysis of certain construction products and systems that, based on other research, have evaluated their LCA, and Construction Period, for the rehabilitation strategies of the “El Rodezno” mill, considering the studies and analyses of Scientific Observation. For the roof solution, we took as an example the rehabilitation of the roof carried out with the same methodology, construction criteria, and prefabricated products analysed in this article and used in the intervention strategies in “El Rodezno”. The paper concludes with the validity of the methodology applied to test the starting hypotheses that lead to intervention strategies that confirm the environmental and economic advantages of industrialised prefabrication, the importance of the design and synergy that results from combining different construction systems, and technologies that improve the acceptance of prefabrication by the inhabitant and boost the circular economy.
