In order to reduce the greenhouse gas (GHG) emissions of buildings, literature has investigated many strategies tackle operational emissions, which are traditionally largest contributor overall emissions. As a result, embodied gaining increased attention, not only due decrease in relative share but also material needs, e.g. use additional thermal insulation buildings. Some these strategies, such as decarbonisation energy grid, could help building materials. The objective this paper is investigate influence renewable electricity production. It examines future trends manufacturing processes – an intensified bioenergy, improvements efficiency and introduction carbon capture storage on GHG These analysed combined "future materials" scenario macro scale within Tyrol province Austria. With focus new residential constructions, six design variations two case studies assessed using life cycle assessment. They then projected 2050 at provincial level. results materials point towards promising reduction, up 19% analysis. Larger mitigation effects would appear 2040s 2050s, meaning technologies can be seen long-term investment. Their reduction potential surpasses impact increase wooden constructions. latter achieved 7% mostly visible early decades rather than later ones. percentages remain lower those attained level, with reductions 72%. obtained discussed light other published regional global identify possible sources variations. Critical reflections storage, well renewables, additionally highlight intrinsic challenges key technologies.
