| چکیده مقاله |
| Climate change is intensifying risks for ecosystems and societies, while anthropogenic greenhouse-gas (GHG) concentrations remain at record levels despite mitigation efforts [1,2]. In Europe, the European Green Deal targets at least a 55% reduction in emissions by 2030 (vs. 1990) and a transition toward net-zero-emission buildings by 2050 [3]. Because buildings contribute roughly one-third of global CO₂ emissions, they are central to decarbonization efforts [4]. Building-emission reductions involve both operational energy use over the service life and embodied impacts from materials and components. Historically, operational impacts have dominated in Europe, which has driven policies focusing on energy efficiency and power-sector decarbonization [5]. At the same time, on-site renewables—especially solar PV—are expanding to support Paris Agreement targets, but their intermittency increases the value of battery energy storage (BESS) [6,7]. A whole-life perspective is therefore needed to avoid burden-shifting from operational to embodied carbon [8,9]. Given the long life of buildings, LCA results depend strongly on time-varying factors such as the evolving electricity mix and material replacement cycles; simplified temporal assumptions can overestimate environmental benefits [10]. To address these limitations, reliability-based approaches can help quantify uncertainty and better assess avoided emissions from technologies such as PV [11,12]. Building on this motivation, this study evaluates how future decarbonization scenarios for the grid and materials, together with on-site renewable generation, influence the environmental performance of new energy-efficient residential buildings. |
