“…Recently, Gulotta et al [20] assessed the energy and environmental impacts related to the reduction of the thermal transmittance of the EU28 building stock (including buildings realized before 1945 up to 2010) through the employment of four different insulation materials: wood board, cork slab, cellulose fibers, and stone wool. In addition, they compared the renovated building stock with the no-renovated option.…”

“…The building types under investigation are urban residential multi-family houses (MHFs) in Italy and representative of three construction periods: 1945-1969, 1970-1989, and 1990-2010. About 93% of the Italian residential houses, both MFHs and single-family houses (SFH), are built before 2010, the year of the first EPBD Directive [21], thus it can be safe to assume that the overall building stock in Italy has a high energy saving potential [20].…”

“…This action allows to reduce the U values of the buildings examined from the original values reported in Section 2 to 0.49 W/(m 2 K). This U value refers to the average transmittance values for MFHs in warm climatic zone calculated in Gulotta et al [20]. The average U calculation method accounts for the different thermal transmittance levels identified for the nZEB concept implementation in EU Member States national legislation on buildings [29].…”

The refurbishment of the building stock is a key strategy towards the achievement of the climate and energy goals of the European Union. This study aims at evaluating the energy and environmental impacts associated with retrofitting a residential apartment to improve its vertical envelope thermal insulation. Two insulation materials, stone wool and cellulose fibers, are compared. The life cycle assessment methodology is applied assuming 1 m2 of retrofitted vertical envelope as functional unit. Moreover, to estimate the net energy and environmental benefits achievable in the retrofitted scenario compared with the non-retrofitted one, a second analysis is performed in which the system boundaries are expanded to include the building operational phase, and 1 m2 of walkable floor per year is assumed as reference. The results show that the use of cellulose fibers involve lower impacts in most of the assessed categories compared to stone wool, except for abiotic resource depletion. In detail, the use of cellulose fibers allows to reduce the impact on climate change up to 20% and the consumption of primary energy up to 10%. The evaluation of the net energy and environmental benefits shows the effectiveness of the retrofit energy policies.

Purpose This paper reviews the state-of-the art research in life cycle assessment (LCA) applied to buildings. It focuses on current research trends, and elaborates on gaps and directions for future research. Methods A systematic literature review was conducted to identify current research and applications of LCA in buildings. The proposed review methodology includes (i) identifying recent authoritative research publications using established search engines, (ii) screening and retaining relevant publications, and (iii) extracting relevant LCA applications for buildings and analyzing their underpinning research. Subsequently, several research gaps and limitations were identified, which have informed our proposed future research directions. Results and discussions This paper argues that humans can attenuate and positively control the impact of their buildings on the environment, and as such mitigate the effects of climate change. This can be achieved by a new generation of LCA methods and tools that are model based and continuously learn from real-time data, while informing effective operation and management strategies of buildings and districts. Therefore, the consideration of the time dimension in product system modeling is becoming essential to understand the resulting pollutant emissions and resource consumption. This time dimension is currently missing in life cycle inventory databases. A further combination of life cycle impact assessment (LCIA) models using time-dependent characterization factors can lead to more comprehensive and reliable LCA results. Conclusions and recommendations This paper promotes the concept of semantic-based dynamic (real-time) LCA, which addresses temporal and spatial variations in the local built and environmental ecosystem, and thus more effectively promotes a “cradle-to-grave-to-reincarnation” environmental sustainability capability. Furthermore, it is critical to leverage digital building resources (e.g., connected objects, semantic models, and artificial intelligence) to deliver accurate and reliable environmental assessments.
