Comparative Life-Cycle Assessment of restoration and renovation of a traditional Danish farmer house

Construction and operation of buildings are a major contributor to environmental impacts. Assessments impacts often focus on new buildings, while studies the existing building stock energy efficiency renovation. However, historical traditional cultural visual importance, which should be kept. Hence, key question is if maintaining original aesthetic via restoration at expense environment or it possible maintain appearance keeping comparable that To investigate this, we conducted Life-Cycle Assessment (LCA) two options: renovation an old from 1887 located Bornholm, Denmark. The scenario focuses use materials house. modern complying with requirements for renovated buildings. results show that, scenarios similar magnitude, performs slightly better in majority impact categories default LCA-model. A Monte Carlo simulation showed in, least, 90% simulations 8 15 categories. This study indicates potentially viable alternative as means keep heritage also levels
