Abstract

In construction sector there is a growing interest in using Life Cycle Assessment to evaluate both embodied and operational carbon emissions during retrofitting interventions. Opting for durable interventions, even in restoration projects, with extended lifespans can result in reduced embodied carbon emissions throughout the building's lifecycle in the near and mid-term future. Preserving historic buildings during restoration poses a significant challenge, necessitating a meticulous selection of materials used for renovation. To this purpose, this paper introduces a novel methodology, named ENVISAGE, that combines Life Cycle Assessment with the concept of nearly Zero Emission Refurbishment. This dual approach aims to align sustainability and preservation goals when selecting materials for retrofitting historic buildings. Furthermore, it seeks to assess the environmental impacts of the entire retrofitting process from the implementation of the intervention to its future maintenance, taking into account the expected 100-year lifespan of a valuable building. By adopting this approach, it is feasible to determine whether this aligns with the principles of the Facility Management in the construction sector. This is one of the main objectives of the paper, namely to find a continuity between Life Cycle Assessment, Sustainability, and Conservation, deciphered in the Facility Management framework. In this perspective, the ENVISAGE method is presented at the light of the Facility Management principles, especially focusing on the principles of "operation and Maintenance" and "Repair and Renovation". Finally, ENVISAGE alignes with Sustainable Development Goals 7, 11, 12, and 13, as it prioritizes reducing water usage, waste generation, and greenhouses emission by promoting renewable energy sources implementation. Emphasizing awareness practices since the stage of the restoration planning, ENVISAGE aims to contirbute to greener and sustainable interventions for existing and historic buildings.
