Improving sustainability of the integrated retrofit by enforcing lct principles in the design phase
In recent years, reducing the impacts of the existing building stock has emerged as a global imperative for the transition to a truly sustainable society. While sustainability is a common goal, how to achieve this goal is site-dependent and specific to each building. In this scenario, integrated, potentially holistic measures that prioritize sustainability, comfort, safety, and resilience were proposed to address the diverse needs of buildings in a context-specific manner. Metrics were defined to calculate impacts and select the best solutions. After initial applications, however, it became clear that equivalent safety and energy efficiency performance could be achieved with very different design choices, resulting in iso-performance solutions with very different impacts. When analyzed from a life-cycle perspective, it emerged that novel design criteria, performance targets, and design specifications are required to make integrated measures more effective than traditional retrofit solutions. To reduce costs, improve well-being, and reduce environmental impacts over the building life cycle, LCT principles have been introduced to guide design professionals through each phase of the intervention design, leading to an extension of the Life Cycle Structural Engineering approach. In addition to safety, structural interventions should pursue new performance along the building LC, i.e.: eco-efficiency to reduce impacts in the construction phase; controlled damage/repairability to improve resilience and reduce costs/impacts in case of natural disasters; durability; maintainability and adaptability to future needs to limit costs/impacts and obsolescence rates in the use phase, possible implementability in incremental rehabilitation plans; ease of disassembly/recycling/reuse to reduce waste at end-of-life. This presentation will discuss these concepts through two actual integrated interventions where LCT principles were enforced in the initial steps of the design; evidence will be provided that LCT criteria ensure the ...
