ECOLOGICAL DUALISMS UNDONE: EXPLORING THE ROLES OF IDEOLOGIES, ZERO WASTE, AND QUALITATIVE LIFE-CYCLE ANALYSIS IN PUNTA CANA’S BUILDING MATERIAL CULTURE A thesis presented to the faculty of the Graduate School of Cornell University in partial fulfillment of the requirements for the degree of Masters of Arts By Jessica Anne Ekblaw January 2012 © 2012 Jessica Anne Ekblaw A B S T R A C T Materials, as the physical human-environment interface, are key challenges and requirements for sustainable design. This study investigates the epistemology of building materials to understand the considerations and consequences of material selection, both in abstract and within the specific context of Punta Cana. By employing reflective research methods to interpret six environmental building philosophies, this study reveals the building community’s need to resolve inflexible dualisms regarding technology, globalization, and cultural meaning to overcome professional divisions that hinder interventions toward sustainability. The results call for common goals, such as zero waste, to explore a wider range of suitable building solutions and provide unified sustainable design criteria. Finally, a qualitative life-cycle analysis suggests that bamboo, a building material commonly disregarded by dualistic mindsets, may convey more environmental, economic, and social benefits in Punta Cana than concrete, the prevailing Dominican structural building material. The conclusions of this study call for increased criticism and ethics throughout the design process to avoid misleading assumptions, represent implicated stakeholders, and promote context-based building solutions. Keywords: sustainable materials, environmental philosophy, zero waste, vernacular, bamboo, Dominican Republic B I O G R A P H I C A L S K E T C H Jessica Anne Ekblaw is an aspiring interior designer and green building professional. She was raised in upstate New York and graduated from Vestal Senior High School in 2006. Her concern for the environmental impacts of buildings grew during her undergraduate attendance at Cornell University, and this interest inspired her to become a LEED Accredited Professional in 2009. In 2010, she received a Bachelor of Science with Distinction from the Design and Environmental Analysis program with a concentration in interior design. Upon graduation, Jessica enrolled in the newly created Sustainable Design Studies graduate program at Cornell University and worked to enrich learning experiences as a teaching assistant for design lectures and studios. By bringing concepts from her graduate minor, Science and Technology Studies, into the design field, she has begun to explore the design process, particularly how designers perceive their material options, and hopes to reveal how assumptions can be questioned to explore sustainable possibilities. iii A C K N O W L E D G M E N T S The insight, assistance, and encouragement of many individuals have been instrumental to the production of this thesis.

The use of dualisms in a complex and dynamic world is problematic because assumptions can preclude consideration of functional, sustainable materials and promote uncritical use of predominant, and often unsustainable, methods. By analyzing the conceptual bases for material use in new construction, this study overcomes the limitations of the many studies that focus on technical solutions alone, which neglect the need for philosophical and lifestyle changes when problems have social, rather than technical, roots.1 By revealing and resolving the underlying values and conditions that fuel divergent thinking regarding technology, sourcing, and cultural aesthetics, designers and the general public
