“…To do so, construction must embrace a multidisciplinary approach with different features to improve building characteristics, which have been the subject of several studies. Some examples of feature studies have investigated materials with improved performance [ 48 , 49 , 50 ], reuse of water and materials [ 51 , 52 , 53 ], reduction of GHG emissions [ 54 , 55 , 56 ] and energy-efficient buildings [ 43 , 57 , 58 , 59 ].…”

The main goal of this study was to review current studies on the state of the art of wood constructions with a particular focus on energy efficiency, which could serve as a valuable source of information for both industry and scholars. This review begins with an overview of the role of materials in wood buildings to improve energy performance, covering structural and insulation materials that have already been successfully used in the market for general applications over the years. Subsequently, studies of different wood building systems (i.e., wood-frame, post-and-beam, mass timber and hybrid constructions) and energy efficiency are discussed. This is followed by a brief introduction to strategies to increase the energy efficiency of constructions. Finally, remarks and future research opportunities for wood buildings are highlighted. Some general recommendations for developing more energy-efficient wood buildings are identified in the literature and discussed. There is a lack of emerging construction concepts for wood-frame and post-and-beam buildings and a lack of design codes and specifications for mass timber and hybrid buildings. From the perspective of the potential environmental benefits of these systems as a whole, and their effects on energy efficiency and embodied energy in constructions, there are barriers that need to be considered in the future.

“…Regarding the life cycle assessment of the assumed integrated retrofit technique, a preliminary step consists in identifying the appropriate system boundaries to be considered. According to UNI-EN 15804:2012 [51], the relevant boundaries generally used when performing a LCCA are: cradle to gate, cradle to site, cradle to handover, cradle to end of use, cradle to grave, and cradle to cradle, but in the definition of embodied energy (EE), common references are cradle to gate and cradle to handover boundaries [39]. Definitions for embodied carbon (EC) were found considering cradle to gate and cradle to handover.…”

“…A sound way to notionally define direct costs of an integrated intervention is the embodied energy (EE): "EE can be defined as the energy consumed during a building whole life cycle; this excludes the operating energy, but includes raw material extraction, product production, manufacturing, installation, on-site construction, maintenance, repair and replacement, and finally the demolition and disposal of a building" [37][38][39]. Embodied carbon (EC) is an analogous concept.…”

Environmental and Economic Impact of Retrofitting Techniques to Prevent Out-of-Plane Failure Modes of Unreinforced Masonry Buildings

This paper presents an innovative methodology to assess the economic and environmental impact of integrated interventions, namely solutions that improve both structural and energy performance of existing masonry buildings, preventing out-of-plane modes and increasing their energy efficiency. The procedure allows the assessment of the environmental and the economic normalized costs of each integrated intervention, considering seismic and energy-saving indicators. In addition, the work introduces in relative or absolute terms two original indicators, associated with seismic displacement and thermal transmittance. The iso-cost curves so derived are thus a powerful tool to compare alternative solutions, aiming to identify the most advantageous one. In fact, iso-cost curves can be used with a twofold objective: to determine the optimal integrated intervention associated with a given economic/environmental impact, or, as an alternative, to derive the pairs of seismic and energy performance indicators associated with a given budget. The analysis of a somehow relevant case study reveals that small energy savings could imply excessive environmental impacts, disproportionally increasing the carbon footprint characterizing each intervention. Iso-cost curves in terms of absolute indicators are more suitable for assessing the effects of varying acceleration demands on a given building, while iso-cost curves in terms of relative indicators are more readable to consider a plurality of cases, located in different sites. The promising results confirm the effectiveness of the proposed method, stimulating further studies.

“…Computation of the life cycle energy and embodied energy is significant because every building component is built using high-energy materials such as steel, cement, burnt bricks, concrete and its products, etc. [10,11]. The usage of these materials has increased considerably, and a huge amount of energy is consumed during their manufacturing and transportation [12].…”

As the building industry takes up a significant part in the energy utilization of a country, builders and engineers are searching for better approaches to limit the energy utilization in buildings in order to prevent environmental pollution [1,2]. The operational energy (OE) of buildings alone corresponds to 30-40% of the complete power consumption globally [3]. The building sector may be looked at while the motorist that is prominent of use and greenhouse gasoline emissions if embodied requirements. Hence, EE and OE linked to building materials and transport requirements linked to the transportation to build people tend to be taken into consideration [4].
