“…related to reductions in environmental pressures resulting from the dynamics hypothesised for the development of the experimental model (mod.2). It is evident, in fact, that the latter approach has a lower impact in terms of exploitation of primary resources [18], as well as in terms of reduction of CO 2 emissions [19][20].…”

Compliance with recent environmental regulations, the demolition phase, within the building replacement process, plays a decisive role, in terms of execution and management methods. The contribution addresses the problems related to the management of the site, in compliance with regulatory requirements for selective demolition and disposal of waste materials. Possible organisational and procedural solutions were investigated with particular reference to the phases of selective demolition (in compliance with Minimum Environmental Criteria), excavation, handling, treatment, recycling, and disposal of waste materials.

“…Table 6 shows the amounts of energy saved at the production, construction, and EOL stages of a building life cycle, along with representing the percentage of energy saved throughout the entire building life cycle by recycling or reusing materials (detailed data on energy saving were available for five studies). Reusing and recycling building materials has already been suggested as an effective strategy to mitigate energy use in the building life cycle by decreasing embodied energy [8,62]. Based on Table 6, it can be observed that this strategy led to the reduction of total building life cycle energy use by the range of 5% to 22%.…”

Application of Life Cycle Energy Assessment in Residential Buildings: A Critical Review of Recent Trends

et al. 2020

Residential buildings are responsible for a considerable portion of energy consumption and greenhouse gas emissions worldwide. Correspondingly, many attempts have been made across the world to minimize energy consumption in this sector via regulations and building codes. The focus of these regulations has mainly been on reducing operational energy use, whereas the impacts of buildings’ embodied energy are frequently excluded. In recent years, there has been a growing interest in analyzing the energy performance of buildings via a life cycle energy assessment (LCEA) approach. The increasing amount of research has however caused the issue of a variation in results presented by LCEA studies, in which apparently similar case studies exhibited different results. This paper aims to identify the main sources of variation in LCEA studies by critically analyzing 26 studies representing 86 cases in 12 countries. The findings indicate that the current trend of LCEA application in residential buildings suffers from significant inaccuracy accruing from incomplete definitions of the system boundary, in tandem with the lack of consensus on measurements of operational and embodied energies. The findings call for a comprehensive framework through which system boundary definition for calculations of embodied and operational energies can be standardized.

“…According to a study on prefabrication methods, the dry building system (with a metal or wood bearing structure) is the most functional design solution. It has emerged that the gap between the construction sector and the mass production industries can be compensated by the adoption of an off-site construction process [101,105]. The construction system in CLT perfectly meets these requirements.…”

The growing diffusion of cross-laminated timber structures (CLT) has been accompanied by extensive research on the peculiar characteristics of this construction system, mainly concerning its economic and environmental benefits, lifecycle, structural design, resistance to seismic actions, fire protection, and energy efficiency. Nevertheless, some aspects have not yet been fully analysed. These include both the knowledge of noise protection that CLT systems are able to offer in relation to the possible applications and combinations of building elements, and the definition of calculation methods necessary to support the acoustic design. This review focuses on the main acoustic features of CLT systems and investigate on the results of the most relevant research aimed to provide key information on the application of acoustic modelling in CLT buildings. The vibro-acoustic behaviour of the basic component of this system and their interaction through the joints has been addressed, as well as the possible ways to manage acoustic information for calculation accuracy improvement by calibration with data from on-site measurements during the construction phase. This study further suggests the opportunity to improve measurement standards with specific reference curves for the bare CLT building elements, in order to compare different acoustic linings and assemblies on the same base. In addition, this study allows to identify some topics in the literature that are not yet fully clarified, providing some insights on possible future developments in research and for the optimization of these products.
