Goal Framing to Encourage More Sustainable Engineering Design Decisions for the Built Environment Across Cultures

The Middle Eastern and North African (MENA) region is one of the fastest developing in the world, however, some of its countries are the slowest in implementing sustainable construction practices. One of these countries is Kuwait, which contributes one and a half times more global greenhouse gas emissions per capita than the U.S. The dissertation starts by identifying potential barriers to more sustainable design and construction practices among professionals in Kuwait. The barriers identified are not technological, but behavioral, related to perceptions of risk and awareness. Behavioral science offers potential solutions to address these barriers through a concept called choice architecture. Professionals who design and construct our built environment use decision tools such as rating systems to inform their design decision making. These tools are inherently embedded with choice architecture. More intentional choice architecture among rating systems that align individual preferences and beliefs may increase the pursuit of more environmentally sustainable design solutions. One form of choice architecture is called goal framing, which describes the outcome of a choice as either a positive consequence of engaging in a behavior or a negative consequence of not engaging in a behavior. Goal framing was applied to the Envision rating system for sustainable infrastructure to emphasize how long-term sustainable outcomes align with decision makers immediate project needs, preferences, and values. Engineering professionals from the U.S. and Kuwait were randomly assigned either the original version of Envision or the goal framed version. The results indicate that goal framing the credits about people and finances, not just the impact on the environment, increased participants motivation and encouraged them to set higher goals for sustainable performance, specifically among professionals who hold a pro-social paradigm of the world. These findings have relevance to those who design, use, and mandate the use of rating systems during the design and construction process of buildings and infrastructure. Future research should continue to explore how engineering professionals make decisions and what choice architecture modifications can support design and engineering towards more sustainable outcomes.
