i CHANGING MINDSETS: SUSTAINABLE DESIGN IN HISTORIC PRESERVATION A Thesis Presented to the Faculty of the Graduate School of Cornell University in Partial Fulfillment of the Requirements for the Degree of Master of Arts by Jennifer Lynn Buddenborg August 2006 © 2006 Jennifer Lynn Buddenborg ABSTRACT At a time of rapid resource depletion and world population growth historic preservation rests at a pivotal point in the advancement of sustainable development and design. Historic preservation is inherently sustainable. Unfortunately, current green building practices focus more on the ever-growing technological innovations that can be applied to new construction. A lack of education and collaboration amongst historic preservation and sustainable design practitioners, scholarly research and publications that join the two fields, and building research, pose additional roadblocks in greening historic preservation in the United States. The question is whether or not historic preservation and green building practice can effectively work together. They can and they do. The key to integration is the changing of mindsets. Educating industry stakeholders as to how and why this linkage can be made is a vital component to effectively taking green building and historic preservation to higher elevations of outreach and implementation. This paper investigates this statement in two ways, by [1] providing a theoretical and evolutionary framework of sustainable design and the inherent role that historic preservation plays within it, and [2] comparing the two sets of standards that guide the two practices: in historic preservation it is The Secretary of the Interior’s Standards for Rehabilitation and in green building it is the widely used Leadership in Energy and Environmental Design (LEED™) rating system. The methodologies used to substantiate these points are varied. They include a literature review of sustainable development publications, a brief survey of the ‘green’ education of State Historic Preservation Officers (SHPO), an analysis of the LEED New Construction (NC) and Existing Building (EB) rating systems and their considerations of historic preservation, and a case study analysis of the green iv rehabilitation/renovation of the Jean Vollum Natural Capital Center in Portland, Oregon. Combined, this analysis proves that historic preservation is inherently sustainable in the most basic sense, and as a result lends itself to green building rating systems. However, it also proves that there are many kinks to be worked out on both sides before a full integration is a reality. The rules and regulations surrounding The Secretary of the Interior’s Standards for Rehabilitation and LEED can be cumbersome, and this paper is a reminder that while both systems are worthy tools in the stewardship of natural and cultural resources, they are not hard and fast rules. They are basic guidelines, and the fusion of the two holds the potential to more closely align the fields of historic preservation and environmental conservation, and to allow the field of historic preservation to assert itself as a viable and integral means to promoting sustainability. iii BIOGRAPHICAL SKETCH Jennifer Lynn Buddenborg was raised in the Great Lakes State in metropolitan Detroit. She attended Wayne State University in Detroit where she earned a Bachelor of Arts in History with a minor in Anthropology. After two and a half years working as a Research Development Coordinator for a social anthropologist at Wayne State University’s Institute of Gerontology, and as a last hurrah before beginning graduate studies, Jennifer set off on a five month thru-hike of the Appalachian Trail from Georgia to Maine. Already possessing a deep interest in the ties between historic preservation and environmental conservation, it was the simple living amongst nature over this 2,174 mile footpath that first introduced her to a sustainable way of life. She tailored this new perspective to her studies at Cornell University and life in Ithaca, New York, where she became involved in the burgeoning field of sustainable design in historic preservation. iii iv ACKNOWLEDGMENTS After completing my thru-hike of the Appalachian Trail I was told by a number of people that I could accomplish anything in life. I knew, however, that writing a Master’s thesis would present me with a formidable task. This proved true. Hence, I have many people to thank for providing guidance and motivation throughout the thesis writing process. First and foremost I would like to give gratitude to my advisor and friend, Michael Tomlan. He kept me afloat in any number of ways, always with the bright light of knowing that we were “moving right along.” Jack Elliott, my second Committee Member, provided the yin to the yang, offering the valuable insight of a LEED accredited professional and, more importantly, the perspective of a like-minded sustainable-living advocate. I could not have asked for a better pairing of minds. My Cornell preservation colleagues: My time in Ithaca would not have been the same without the close ties I made with Alec Bennett, Liz Blazevich, Jayme Breschard, Jess Evans, and Matt Gundy. Sara Shreve, a late installment in our initial group of six, became my compatriot in the world of thesis, and good friend. In addition, all of the amazing friendships made during my extra year in Ithaca, and those friendships that followed me to Ithaca, provided much needed support and, oftentimes, mind-clearing distraction. A certain gap-toothed friend, who shall remain somewhat anonymous, deserves special thanks for never giving up faith in me. And of course my family, who ever so gently poked and prodded, providing unceasing support. It is my parents, I believe, who deserve the accolades for this thesis, for without their love and encouragement, I may never have landed where I have today. iv v TABLE OF CONTENTS Biographical Sketch iii Acknowledgements iv List of Figures vii List of Tables viii Introduction 1 Chapter One: Sustainable Design: A Fuzzy Concept or a Concrete Goal? 11 Definition of Sustainability 12 Definition of Sustainable Design 16 Joining Historic Preservation and Sustainability 26 Conclusion 29 Chapter Two: Reinventing the Wheel, With an Added Spoke 30 The Industrial Revolution and the Machine Age 32 Post-World War II Development 35 1960s and 1970s Environmentalism 36 Toward a Modern Sustainable Design 46 Conclusion 61 Chapter Three: A Look at LEED 63 A History of LEED 64 How LEED Works 70 Analysis and Criticism 74 Conclusion 83 Chapter Four: Standard v.

The concept of sustainability in all of its various forms and definitions has become common to our everyday vocabulary. In the world of architecture it takes on various monikers, including ‘high-performance design,’ ‘integrated design,’ ‘sustainable design,’ or ‘green building.’ Buildings negatively impact people and the environment through the over- consumptive use of virgin materials like wood and minerals, energy resources, and water, and the production of waste and unhealthy indoor air. They account for one- sixth of the world’s freshwater withdrawals, one-quarter of its wood harvest, and two- fifths of its material and energy flows.1 Such significant resource use wreaks havoc on our environment, causing deforestation, air and water pollution, stratospheric ozone depletion, and the risk of global warming.2 And within the construction of most modern buildings about half of the energy used in the building construction and operation is expended in creating an artificial indoor climate in heating, cooling, ventilation, and lighting systems, a climate that often leads to sick building syndrome.3 These numbers alone should encourage the preservation and green retrofit of our existing built environment to reduce resource use and health threats, as opposed to the wasteful enterprise of demolition and new construction.
