  • Sustainability Spotlight: Dr. John Crittenden

    Interviewed by Joseph Buehler, Student Assistant, Georgia Tech Campus Sustainability.  Republished with permission.

    Since 2009, Dr. Crittenden has led the BBISS at Georgia Tech.  He took a moment to describe some of the Institute's projects:

    "BBISS has worked on problems such as the decentralization of energy and water. In the past our infrastructure was optimized in a silo fashion, where each provider focuses specifically on their product. We look at connecting those and optimizing the system as a whole. An example that we have looked into is a combined heating cooling and power system. Basically it is a device that creates electrical energy and gives off heat. If this is close to where you live, then you can utilize that heat. In terms of water, Atlanta gets about 45 inches of rainwater per year. According to our calculations that could provide 40-50 percent of water demands. Collecting that water for use also reduces the energy impact associated with getting water because it no longer needs to be pumped from a plant to your sink. All of these play into community design which is truly dictated by what the people living there want. For a grant, we are analyzing surveys from the Atlanta Regional Commission to help determine the best way to integrate more sustainable systems into an already large infrastructure system. We have learned that the adoption rate of technologies is higher when the technologies are provided in packages and systems."

  • BBISS Fellow Dilkina and Post-Doc Lu to Study Decentralized Water and Energy Systems

    In the not-too-distant future, water and energy harvested by individuals, communities and other non-traditional systems – think rain barrels, grey water recycling, solar panels and windmills – may be integrated into centralized municipal networks.

    With these added resources flowing into existing municipal systems, water and energy supplies around the world could become more sustainable, more resilient, and more secure in the face of potential natural disasters and possible security threats.

    However, according to School of Computational Science and Engineering Assistant Professor Bistra Dilkina, getting to a point where this is possible on a broad scale is not going to be easy.


  • BBISS Grad Student to Receive ARCS Scholar Award

    Congratulations to BBISS Graduate Research Assistant Osvaldo Broesicke for receiving a 2016-17 Scholar Award from the Achievement Rewards for Academic Scientists (ARCS) Foundation.  The $7,500 scholarship recognizes outstanding doctoral students who have a record of past achievement and who show exceptional promise of making a significant contribution to the worldwide advancement of science and technology.  Osvaldo, a Ph.D. candidate in Georgia Tech’s School of Civil and Environmental Engineering, researches the interconnections between the infrastructure systems of urban areas, what we at the BBISS refer to as Infrastructure Ecology.



  • The Brook Byers Institute for Sustainable Systems’ Work in China

    China is urbanizing at an unprecedented level.  Highways, energy grids, water treatment facilities, indeed, entire cities seem to be springing forth from the Chinese landscape.  One of our main topics for research at the Brook Byers Institute for Sustainable Systems is what we call Infrastructure Ecology.  It is becoming obvious to many that the way we have been building infrastructure is not sustainable.   At the same time, much of the infrastructure in the developed world is nearing the end of its designed lifespan.  Urbanized lifestyles are not going away, in fact, they are accelerating.  It stands to reason, then, that we need new ways to think about how we build, operate, maintain, and inhabit our cities.


  • Urban Food Systems Workshop Report

    In June 2016, Georgia Tech and the Georgia Tech Research Institute released a report entitled “Urban Food Systems: Workshop Report on the Potential for Growth and Innovation in Commercial Scale Urban Agriculture at the Nexus of Food, Energy, Water, and Transportation Systems.”  Sponsored by the National Science Foundation (NSF), the report summarizes the findings of two workshops and makes recommendations for funding research within NSF’s new Innovations in Food, Energy, and Water Systems research initiative. 

    More than conventional agriculture, urban agriculture presents the greatest and most immediate opportunity to fully integrate food, energy, and water systems owing to the proximity of human, industrial, water, power, and transportation resources in cities. But while small scale urban agriculture is growing as a practice, progress at the commercial scale is hampered by many technological and knowledge barriers. The workshops surfaced, and the report conveys, 25 research topics that address barriers to commercial scale urban agriculture and the integration of food, energy, and water systems. Included among the 25 are:


  • How to Think About the Largest Things that We Build

    Cities are the largest technological artifacts that we build.  We can see them from space.  At the opposite end of the spectrum, we call the things that we build which can’t be seen with the naked eye “nanotechnology.” But we don’t have a name for the largest things we build other than “cities.”  “City” is useful as a name because we all know what is meant when the word “city” is used even though formal definitions are surprisingly vague and inadequate. We understand a city as a very large permanent human settlement comprised of all the built, natural, human, political, and economic elements within its borders; however, we don’t really understand how the mechanical and technological systems of cities function together.  How can it be that we don’t understand how cities work when we design, build, operate, maintain, and inhabit them?  We are just beginning to explore the answers to this question.  One of the things that we are learning is that it will be useful to distinguish between what we understand as a city, which includes all of the human elements, and the underlying technological artifacts that facilitate the feasibility of cities. Perhaps a better name for humanity’s largest artifacts, such as cities, would be “gigatechnology.”

  • Crittenden Awarded Clarke Prize

    The National Water Research Institute (NWRI) announced that BBISS Director, John C. Crittenden, will be the twenty-second recipient of the NWRI Athalie Richardson Irvine Clarke Prize for excellence in water research. Consisting of a medallion and $50,000 award, the NWRI Clarke Prize is given each year to recognize research accomplishments that solve real-world water problems and to highlight the importance of the continued funding for water research. Crittenden was selected as the 2015 recipient for his outstanding contributions to treating chemical contaminants in water and his leadership in addressing water demand for transportation, energy production, and domestic use in a holistic, sustainable manner. “I consider the Clarke Prize to be one of the greatest honors that one who conducts water research can receive,” said Crittenden.

  • BBISS Appoints Twelve Fellows

    The Brook Byers Institute for Sustainable Systems at Georgia tech has appointed 12 BBISS Fellows.  This diverse group of faculty and researchers come from all six of Georgia Tech’s Colleges as well as the Georgia Tech Research Institute.  The purpose of the Fellows program is to serve as a board of advisors to the BBISS; to foster the culture and community of sustainability researchers, educators, and students at Georgia Tech; and to communicate broadly the vision, mission, values, and objectives of the BBISS.

  • Grant to Study Regional Industry, Economic Resilience and Energy Consumption

    The National Science Foundation has awarded a three year, $300,000 grant to understand how regional economic activities and energy use interact with each other. The effort is led by Georgia Tech School of Economics Assistant Professor Juan Moreno-Cruz with BBISS Director John Crittenden serving as Co-PI.

  • Brook Byers Professors Appointed

    In January 2014, three distinguished faculty were named Brook Byers Professors:  Bert Bras (Mechanical Engineering), Marilyn Brown (Public Policy), and Elsa Reichmanis (Chemical and Biomolecular Engineering). Made possible by a gift from Shawn and Brook Byers, a 1968 Georgia Tech alumnus in Electrical Engineering, the Brook Byers Professorships provide resources to enable and enhance cross-disciplinary, collaborative research and education in sustainability, energy, and water. Recommended by their peers, the three recipients were chosen by the Provost and approved by the Board of Regents. The appointments recognize superior scholarly achievement and the potential for further progress. The Brook Byers Professorship is the highest title bestowed at Georgia Tech for those specifically engaged in sustainability related research and education.

  • Sustainability Quantified: The ‘Gigaton’ Problem

    The anthroposphere (the place where humans live and where human needs are provided for) needs to be recreated to exist within the means of nature. Two important implications can be drawn from this statement: (1) we must use renewable materials that nature provides, and (2) we must not overwhelm natural cycles such that they cease to provide appropriate ecosystem services. The world economy currently uses 70 Gt of materials [1], only 29% of which are renewable (Fig. 1) [2]. Excluding food and fuel from this 70 Gt results in approximately 15Gt of which only 4% is renewable. Human intervention has disrupted nitrogen, phosphorous, water, carbon and other cycles and affected human and ecosystem health through discharges of toxic compounds.

  • Tsinghua University Students visit BBISS

    Earlier this month, eight students and one faculty member from Tsinghua University’s School of Environment visited Georgia Tech for two weeks as part of a student exchange program. It was funded by a cost sharing collaboration between Tsingua University and the BBISS. The exchange provided a cultural and academic forum for students studying many aspects of sustainable urban systems to learn from each other while gaining a cultural perspective that only international travel can foster.

  • BBISS Researchers Tour Eco-Cities in China

    It would be no surprise to anyone to hear that China is well into a building boom.  The nation is very rapidly urbanizing due to its expanding manufacturing sector.  Large cities are being constructed from scratch where there once was open rural land.  It might surprise some that many of these will be eco-cities, designed and constructed with sustainable design features, materials, and infrastructure systems.  The speed and scale of these projects affords a rich opportunity for research and innovation towards a better understanding of what constitutes an “eco-city” in the real world.
