“…In more recent studies, researchers have implemented concepts of PBEE. In comparison to HAZUS, PBEE has been used for more detailed studies that include a configuration of damageable components, including the direction of components and floor location of these components (Chhabra et al 2018;Clemett et al 2022;Hossain and Gencturk 2016;Huang and Simonen 2020;Welsh-Huggins et al 2020;Liel 2015, 2018). Ramirez et al (2012) demonstrated that HAZUS could lead to underestimation of damages and losses, compared to using the PBEE's methodology by a factor of 1.6-2.4 times using a concrete building case study.…”

“…Some researchers have conducted scenario-based assessments (Comber and Poland 2013;Simonen et al 2015) and risk-based assessments (e.g. time-based, multiple-stripe) (Clemett et al 2022;Wei et al 2016a, b;Welsh-Huggins and Liel 2018).…”

“…Planar (2D) models also have been used for structural analysis in some studies (Chhabra et al 2018;Hossain and Gencturk 2016;Welsh-Huggins et al 2020;Welsh-Huggins and Liel 2018). Tridimensional models have been used for considering optimal retrofitting of an existing building considering environmental impacts (Clemett et al 2022). In another recent approach, for example, Gavrilovic and Haukaas (2021) employed finiteelement models created from BIM models based on visual damage to determine the cost of environmental damage.…”

“…This methodology has been used to translate seismic repair activities to environmental impacts in several studies in the US (Comber et al 2012;Comber and Poland 2013;Huang and Simonen 2020), and it has been implemented in Performance Assessment Calculation Tool (PACT) (Simonen et al 2018) developed by FEMA. Clemett et al (2022) implemented the EIO approach and adjusted the US cost consequence to the national context to calculate environmental consequences for repair activities in Italy. In that work, researchers used the approach by Silva et al (2020) to translate the cost of the seismic repairs to European values and use these economic values to calculate environmental metrics for seismic repairs.…”

Seismic losses due to earthquakes have been shown to have significant economic, social and environmental consequences. Over recent years, research to predict potential economic and social impact due to seismic risk has been increasing. Recognizing that the traditional philosophy of life safety design can lead to extensive damage and demolition which has a large environmental cost, incorporating environmental impacts associated with the expected seismic damage over a building’s life is a key step as the building industry moves towards both sustainable and seismically resilient design. This paper introduces a framework that uses environmental indicators quantifying losses from seismic response that can then be used to advocate for a change in seismic performance objectives. First, existing literature and previously developed approaches for quantifying potential environmental impact due to seismic damage are summarized. Next, performance based earthquake engineering concepts are used to demonstrate a probabilistic approach to quantify potential environmental impacts using a range of environmental and resource use indicators over the life span of a case study building. In addition, a case study is presented to compare different environmental indicators between a Code Minimum building and the same building redesigned for a higher seismic performance. The majority of the composition of the environmental indicator values are from the inclusion of the non-repairable scenario, and from the repair activities, the majority of the impacts are from damage to drift sensitive components including curtains walls, partitions and elevators. For the Code Minimum building the non-repairable scenario contributes to between 8 to 11% the total seismic cost. For the Stronger Stiffer building, the non-repairable scenario contributes around 3% of the initial impact. Neglecting non-repairable scenarios does significantly reduce the potential environmental impacts when analyzing buildings designed for current code minimum structural standards.

“…The choice of the best and worse solutions is then made by calculating the distances of each retrofit option to fictitious positive and negative solutions. An applicative study of this approach was carried out by Clemett et al (2020), including environmental impacts among the set of decisional variables considered.…”

Multi-criteria decision-making approach for optimal seismic/energy retrofitting of existing buildings

et al. 2023

Given the current climate emergency and the ambitious targets of carbon emissions reduction worldwide, retrofitting strategies on existing buildings are typically aimed at reducing their energy demand, decarbonizing the power supply, and addressing embodied carbon stored in construction materials. However, the contribution of potential earthquake-induced impacts has been traditionally not considered, while the consequences of several past events highlighted their relevant impact on the environment due to post-disaster rehabilitation activities. This study presents a multi-criteria decision-making approach for the identification of optimal renovation strategies for existing buildings, based on economic and environmental life cycle impacts (including both earthquake-induced losses and energy consumption), payback period of the retrofit investment and expected loss of life due to seismic hazard, through its application to a case-study building. Such parameters are thus suggested as meaningful decision-making variables for the choice of the best retrofitting strategy for a given building, that is the one that leads to an optimal balance between reduction of seismic vulnerability and increase of energy efficiency, based on the climatic conditions and the seismic hazard at the site of interest.
