“…Incremental rehabilitation, instead, is a strategy that allows one to distribute retrofit actions in time, combining them with programmed maintenance interventions, as long as each step increases the performances of the building with respect to the previous one. This allows a reduction in the impact of the second major barrier, which is the economic barrier connected to the construction cost [52][53][54].…”

The decarbonization of the construction sector, which is one of the most impactful sectors worldwide, requires a significant paradigm shift from a linear economy to a circular, future-proofed and sustainable economy. In this transition, the role of designers and structural engineers becomes pivotal, and new design objectives and principles inspired by Life Cycle Thinking (LCT) should be defined and included from the early stages of the design process to allow for a truly sustainable renovation of the built environment. In this paper, an overview of LCT-based objectives and principles is provided, critically analyzing the current state of the art of sustainability and circularity in the construction sector. The effectiveness of applying such design principles from the early stages of the design of retrofit interventions is then demonstrated with reference to a case study building. Four seismic retrofit alternatives made of timber, steel and concrete, conceived according to either LCT principles or traditional, were designed and compared to a demolition and reconstruction scenario on the basis of five common environmental impact indicators. The indicators were calculated adopting simplified LCA analyses based on Environmental Product Declarations (EPDs), considering the product and End of Life stages of the building. The results of the comparative analyses confirm that LCT-based retrofit solutions are less impactful than both the traditional seismic retrofit interventions and the demolition and reconstruction scenario.

“…Previous studies have pointed out that ISR could be very advantageous in situations of limited economic resources and a great amount of buildings at risk (Dutu et al, 2013; Labo et al, 2018). Demountable dry rehabilitation techniques which may be assembled in different phases of the ISR were identified as suitable solutions for school rehabilitation due to the low invasiveness (Labo et al, 2020).…”

Life-cycle cost analysis for an incremental seismic rehabilitation project

Incremental seismic rehabilitation (ISR) consists of a set of discrete rehabilitation actions in order to decrease initial costs and to avoid long-lasting disruptions. Nevertheless, there are few cases of incrementally retrofitted buildings and few studies about its economic feasibility. The objective of this work is to evaluate the differences between incremental and single-stage rehabilitation in terms of economic losses during the building’s life span. For this purpose, this work analyzes three rehabilitation proposals to improve seismic performance of typical school buildings. Based on P58 FEMA (Federal Emergency Management Agency) methodology, expected repair costs and benefits were calculated for each rehabilitation intervention. Results confirm the potential of ISR for improving essential buildings.
