Sustainable & Resilient Building Design

Buildings are major consumers of energy and material resources and can be vulnerable to natural and man-made hazards. Poor performance of a building in a number of areas, like structural integrity and energy use, can result in disruption to the regular functionality of the building and even communities. Bringing buildings back to full operation after a disruptive event can result in additional resource consumption and life cycle impacts. Making building more material, energy, and water efficient can, in turn, make them more resilient, and on-site energy generation, water collection, and water treatment may ensure continuous functionality during disruptions to the grid. This research area focuses on evaluating the sustainability and resilience of buildings during the design phase but also analyzes impacts of existing buildings and rating systems.

This project was funded by the National Science Foundation: Collaborative Research RSB: A Sequential Decision Framework to Support Trade Space Exploration of Multi-Hazard Resilient and Sustainable Building Designs

Sustainability & Resilience Metrics

There is some consensus on the factors influencing building resilience and sustainability, and both have been studied individually to inform codes and rating systems; however, little has been done in the quantification and analysis of the two aspects side by side and in regards to buildings. The goal of this research is to define quantitative metrics for characterization of building systems and components and their effect on the sustainability and resilience of the building as a whole. The approach and metrics focus on the early design phase, creating a platform for performance-based design of sustainable and resilient buildings.

Life Cycle Structural Resilience to Natural Hazards

Our approach to the quantification of sustainability and resilience of building designs builds on the typical whole building life cycle assessment approach. While typical building LCA focuses on operational energy use and embodied energy in building materials, our approach also includes earthquake engineering and water treatment methods to expand the scope of the assessment, and consider the structural integrity and water demand of the building.

Building-Scale Water Impacts and Self-Reliance

The diversity of building systems and self-reliance of the building from an energy and water standpoint is also important for the resilience of the building. As part of the development of computational approaches in this regard, and to be able to relate such building characteristics to the life cycle assessment approach, we have extensively studied a local net-zero energy and water building.

Parametric Life Cycle Assessment & Costing

This study explored the use of LCA results of parametrized reference buildings for benchmarking purposes and compared them to real building projects. The building performance is calculated using an automated process of energy modeling, life cycle assessment and costing, and seismic loss assessment. The physical model was based on the Department of Energy (DOE) Medium Office Reference Building and is adjusted using a Python algorithm based on inputs of building shape, length, width, floor-to-floor height, number of stories, and window-to-wall ratio (WWR).

The framework was used to obtain the total life cycle results for a 60-year study period for 4,608 unique design and service scenarios across seven environmental and economic metrics and two locations. Each building was represented by a single circle. As an example, the black circles in the plot below represent a single building design and service combination scenario out of the 4,608 possibilities. Many of the results were so close to each other that the circles formed a visually continuous line, but in fact they were many clustered circles. This clustering indicated that there were many buildings whose design or service decision differences yielded very small differences in the overall results in that metric. Conversely, large gaps between these clusters indicated a major influencing factor splitting the results clusters apart.


The application of the framework on the medium office building used a combination of modeled and average reported data, making it sort of a hybrid approach. Future studies could make more homogenous approach in either full bottom-up modeling of all aspects or top-down assessment based entirely on reported data. The specific scenario analyzed in this case showed a potential for revealing the worst case and best case scenarios in various performance metrics and revealed the influence of individual life cycle stages. Future studies could expand the number of considered materials, constructions, service options and other aspects affecting building performance. Once it is possible to generate more sophisticated building models and design and service options, the presented approach could be used to generate baseline buildings for real building projects.
