“…Considering the building life time, the designer should also account for the climate change. C. Roux et al (2016) performed a LCA and life cycle cost (LCC) assessment and X. Song et al (2017) an energy consumption analysis on residential buildings, both incorporating a weather data prediction on the climate on future years.…”

“…First, a shift toward renewable energy sources is expected (Passer, Ouellet‐Plamondon, Kenneally, John, & Habert, ), which would benefit not only the building's use phase, but also the production impacts of the building's components. Global warming's influence on life cycle impacts should also be analyzed (Roux, Schalbart, Assoumou, & Peuportier, ). It is likely that in European countries, heating demands will decrease but cooling demands increase (Berger et al., ).…”

The built environment is the largest single emitter of CO2 and an important consumer of energy. Much research has gone into the improved efficiency of building operation and construction products. Life Cycle Assessment (LCA) is commonly used to assess existing buildings or building products. Classic LCA, however, is not suited for evaluating the environmental performance of developing technologies. A new approach, anticipatory LCA (a‐LCA), promises various advantages and can be used as a design constraint during the product development stage. It helps overcome four challenges: (i) data availability, (ii) stakeholder inclusion, (iii) risk assessment, and (iv) multi‐criteria problems. This article's contribution to the line of research is twofold: first, it adapts the a‐LCA approach for construction‐specific purposes in theoretical terms for the four challenges. Second, it applies the method to an innovative prefabricated modular envelope system, the CleanTechBlock (CTB), focusing on challenge (i). Thirty‐six CTB designs are tested and compared to conventional walls. Inclusion of technology foresight is achieved through structured scenario analysis. Moreover, challenge (iv) is tackled through the analysis of different environmental impact categories, transport‐related impacts, and thickness of the wall assemblies of the CTB. The case study results show that optimized material choice and product design is needed to reach the lowest environmental impact. Methodological findings highlight the importance of context‐specific solutions and the need for benchmarking new products.

“…Häflinger et al [25] showed the importance of sensitivity analysis of different types of materials, which can result in significant different results depending on the modelling. Roux et al [26] performed a building's LCA with climate change scenarios and the development of the French energy mix. It showed that these future scenarios have a major impact on LCA results.…”

Life Cycle Assessment of Building Renovation Measures–Trade-off between Building Materials and Energy

The scope of this study is to assess how different energy efficient renovation strategies affect the environmental impacts of a multi-family house in a Nordic climate within district heating systems. The European Union has set ambitious targets to reduce energy use and greenhouse gas emissions by the year 2030. There is special attention on reducing the life cycle emissions in the buildings sector. However, the focus has often been on new buildings, although existing buildings represent great potential within the building stock in Europe. In this study, four different renovation scenarios were analyzed with the commercially available life cycle assessment software that follows the European Committee for Standardization (CEN) standard. This study covers all life cycle steps from the cradle to the grave for a residential building in Borlänge, Sweden, where renewable energy dominates. The four scenarios included reduced indoor temperature, improved thermal properties of building material components and heat recovery for the ventilation system. One finding is that changing installations gives an environmental impact comparable to renovations that include both ventilation and building facilities. In addition, the life cycle steps that have the greatest environmental impact in all scenarios are the operational energy use and the building and installation processes. Renovation measures had a major impact on energy use due to the cold climate and low solar irradiation in the heating season. An interesting aspect, however, is that the building materials and the construction processes gave a significant amount of environmental impact.
