Challenges Against Hiring Native American Engineering Faculty: An Institutional Perspective

[Accepted] 2020 Construction Research Congress (Conference Paper)

Engineering schools have been unable to recruit Native American (NA) faculty in the United States. Consequently, NA engineering students lack role models in academia, and research universities miss the opportunity of producing research that is relevant to NA issues. To understand what are the challenges to hiring NA faculty as perceived by the institutions, the authors interviewed engineering Deans from various research institutions across the country.

Design for disassembly: An analysis of the practice (or lack thereof) in the United States

[Accepted] 2020 Construction Research Congress (Conference Paper)

This study aims at identifying the barriers and opportunities for Design for Disassembly (DfD) and building components reuse in the current design practice in the United States. The authors recorded, transcribed, and coded open-ended interviews with 13 architects from large design firms in the United States in order to answer the question of why architects do not currently design for disassembly.

Project Validation: A Guide to Improving Owner Value and Team Performance

May 2019, Lean Construction Institute (Report)

Project Validation aims at proving or disproving with limited or no design whether the team can deliver a project that satisfies the owner’s business case and scope within the owner’s allowable constraints of cost and schedule and with an acceptable level of risk. It sets the commitment of the team towards achieving project goals and accepting the shared risks of failure to do so. . This Guide is the result of a primary research effort by the Lean Construction Institute (LCI) to document validation and provide guidance to practitioners. 


Reusing exterior wall framing systems: A cradle-to-cradle comparative life cycle assessment

May 2019, Waste Management (Journal Article)

Can reuse offset the environmental impacts of materials with high embodied energy (e.g. steel)? If so, in what conditions? In the study presented in this paper, the authors used two different life cycle assessment (LCA) methods to compare a single-use wood-framed wall against a reusable steel-framed wall in a tiny house in the U.S. The analyzed impact categories were global warming potential, embodied energy, and water use.  


Circular Economy in the Built Environment: Designing, Deconstructing, and Leasing Reusable Products

2019, Reference Module in Materials Science and Materials Engineering (Elsevier Encyclopedia)

This article summarizes the efforts and opportunities associated with the implementation of a circular economy (CE) approach in the built environment. The concepts of Design for Disassembly and Product-service Systems are investigated and discussed at large in this article as fundamental resources in support of the challenging implementation of CE in the built environment. 


Project Validation – A Novel Practice to Improve Value and Project Performance

July 2019, International Group for Lean Construction (Conference Paper)

Project validation aims at proving or disproving with limited or no design whether the team can deliver a project that satisfies the owner’s business case and scope within the owner’s allowable constraints of cost and schedule and with an acceptable level of risk. This article characterizes what validation is, when it is performed, how it should be implemented, and its benefits.  When properly implemented, subject matter experts express that validation virtually eliminates cost and schedule deviations. 


Beyond Recycling: Design for Disassembly, Reuse, and Circular Economy in the Built Environment

May 2018 (Doctoral Dissertation)

Dealing with resource scarcity demands us to think beyond the incremental changes from recycling waste; it demands an urgent, systemic, and radical change in the way we design, build, and procure construction materials. This dissertation aims to answer three research questions: 1) How can researchers estimate the environmental benefits of reusing building components, 2) What variables are susceptible to affect the environmental impact assessment of reuse, and 3) What are the barriers and opportunities for Design for Disassembly and materials reuse in the current design practice in the United States.  


Steel or Wood Frame? A Life Cycle Comparison of External Wall Systems through Deconstruction and Reuse

April 2018, Construction Research Congress (Conference Paper)

This study compares the embodied energy, global warming potential, and water use of a wood frame and a steel frame for a manufactured home in the United States. The analysis assumes the wood frame would be demolished and rebuilt for three life cycles, while the steel frame was assumed to be continuously reused. The analyses showed that, by using a cradle-to-cradle (C2C) framework, both methods generate conflicting results. The impact of the results to manufacturers, designers, policy-makers, building owners, and researchers are discussed. 


The need for detailed gender-specific occupational safety analysis

June 2017, Journal of Safety Research (Journal Article)

According to past studies, women suffered from workplace injuries and illnesses that were less prominent among men.  In this paper, the authors analyze prior public data on fatal and nonfatal injuries to understand why we need to differentiate genders when analyzing occupational safety and health issues. Also, the reader will become aware of the current lack of data and knowledge about injuries and illnesses separated by gender and industry. 


Analyzing the Impact of Outside Temperature on Energy Consumption and Production Patterns in High-Performance Research Buildings in Arizona

February 2017, Journal of Architecture Engineering (Journal Article)

This study uses continuous real-time data from four high-performance research buildings and presents the results from a set of correlations and regression analyses between several variables, i.e., outside temperature, heat index, electricity consumption, and the production of solar energy. The authors found no relationship between electricity use and outdoor temperature, and between electricity use and heat index. Conversely, the efficiency of the production of solar energy was affected negatively by higher outdoor temperatures.


Low-Investment Energy Retrofit Framework for Small and Medium Office Buildings

May 2016, Procedia Engineering (Conference Paper)

We present an eight-steps framework for an energy retrofit assessment in small and medium office buildings. Through a bottom-up approach and a web-based retrofit toolkit tested on a case study in Arizona, this methodology was able to save about 50% of the total energy consumed by the case study building, depending on the adopted measures and invested capital. While the case study presented is a deep energy retrofit, the proposed framework is effective in guiding the decision-making process that precedes any energy retrofit, deep or light. 


Women and Accidents: The Need to Separate Gender Database

May 2016, Procedia Engineering (Conference Paper)

This study shows that women faced different types of workplace hazards and the risks have been increasing over the past years. Some analysis suggests that some jobs better protect women and the others. The study also finds that there is a lack of understanding of the different safety issues each gender faces, and the lack of data or separation of data between genders. This paper focuses on the main events of fatal and nonfatal injuries among women in all industries, especially on homicides and assaults to shed lights on the gender gaps on safety issues and the need for more gender-specific research and data. 


Design for Disassembly and Deconstruction - Challenges and Opportunities

May 2015, Procedia Engineering (Conference Paper)

This study aims to find the challenges in the current practice of deconstruction activities and the gaps between its theory and implementation. Furthermore, it aims to provide insights about how Design for Disassembly can create opportunities to turn these concepts into strategies that can be largely adopted by the construction industry stakeholders in the near future.
