With the increasing number and diversity of disruptive events imposed on the built environment, it is becoming more important to identify a system's resilience. Quantifying resilience is crucial because it enables effective preparation, recovery, and adaptation to the uncertainties that lie ahead. This study focuses on the resilience of building facades, which play an integral role in a building's various functions, including environmental, structural, and operational performance. Facades contribute significantly to the total building damage, yet their resilience is not sufficiently addressed in current discourse. This research aims to bridge this research gap by addressing the question: How can the integrated resilience of a facade system to multiple hazards be identified? A methodology was developed with two objectives: 1) evaluating facade resilience, and 2) integrating this methodology into the facade design process.

The Resilience-based Facade Design Framework assesses the impact of multiple hazards on a building facade, taking into account its fragility. The framework provides a quantitative approach to decision-making regarding facades, both in the early design stage and in retrofitting. Users can input project location, building geometry, and existing facade specifications to create a facade package. This package is then assessed for resilience under different hazards, including seismic and heat hazards. The resilience performance, defined in terms of resilience loss and economic loss, is integrated into a multi-attribute decision-making tool. This tool allows users to select a facade package based on its integrated resilience performance value, or to configure a facade package based on individual enhancements to resilience attributes.

Climate change and extreme heat are critical issues which have been faced all over the world. Consequently, designers strive to monitor and assess the performance of facades by developing environmental assessments at the early design stages, since design changes do not require many resources. Rapid urban expansion in many parts of the world is leading to increased exposure to extreme natural hazards, exacerbated by climate change. It is essential to come up with strategies for mitigating the vulnerability of the built environment. The concept of thermal resilience and adaptation to climate change have gained ground and international attention in the Architecture, Engineering and Construction (AEC) industry. Resilience is a multi-facet property which defines the vulnerability of the built environment. Although the qualitative assessment of resilience value, the quantification of urban resilience is not yet representative enough and there is a lack of calculating the resilience in the built environment. However, designers are called to develop building and planning proposals with taking into consideration the thermal resilience of buildings against extreme hazards. This thesis aims to fill the gap between the qualitative and quantitative evaluation of thermal resilience in buildings by considering the operational building performance and the thermal performance of the building envelope in case of extreme heat waves. Towards this direction, the most influential parameters of thermal resilience are identified by implementing a sensitivity analysis process, in the first part. Secondly, a quantification method is presented and the thermal resilience performance for buildings in Amsterdam is calculated. Last, this thesis attempts to develop a computational workflow in order to assist designers and engineers in defining the thermal resilience index from the early design stage. Defining a less computational cost and time-consuming workflow is also a goal. Due to time limitations, the multi-facet aspect of resilience and the difficulty of quantification of its indicators, this research focuses on the ex-ante evaluation of the building envelope by identifying its vulnerability to extreme heat waves.
