Harvey Mudd College Biennial Conference for Sustainable Design and Solutions
The Biennial Conference for Sustainable Design and Solutions is one of Harvey Mudd College’s staple sustainability events. Organized and hosted every two years by the Hixon Center, the conference welcomes students, faculty and staff from across the Claremont Colleges, as well as sustainability professionals and government officials from around the state of California and the country, to attend, present, and lead workshops at the conference.
2018 Sustainable Design and Solutions Conference – Thank you for attending!
The 2nd Biennial Conference for Sustainable Design and Solutions took place on Friday, October 5th, 2018. Most sessions were held in the R. Michael Shanahan Center for Teaching & Learning and in the Platt Campus Center. The conference was a successful zero-waste-to-landfill event. We thank everyone for attending, and look forward to seeing you again in 2020!
About the Conference
The first Sustainable Design and Solutions Conference was held on October 8th, 2016. The conference, held every two years, intends to raise academic and personal awareness regarding environmental sustainability issues on local, regional and global scales. More specifically, the conference is centered on design – focusing on methods and processes we apply to create sustainable solutions. We must train individuals to carry a multidisciplinary knowledge of environmental issues, and to apply a transdisciplinary approach to finding and implementing sustainable designs and solutions. This requires us to embrace the fluid, creative and sometimes nebulous processes inherent in addressing environmental problems.
In other words, how we achieve sustainable solutions is just as important as the solutions themselves.
To learn more about the conference, please visit the official conference website (hmc.edu/sds-2018).
Note: Accessible online versions of the 2018 and 2016 conference programs are available below.
2018 Conference Program
- Environmental Policy and Sustainability: An Environmental History
Teresa Spezio, Visiting Assistant Professor, Pitzer College
In this presentation, Professor Spezio will discuss how an oil spill off the coast of Santa Barbara in 1969 gave environmental decision makers the ability to develop a proactive approach to comprehensive federal environmental policy. Exploring the interconnections between the National Environmental Policy Act of 1970 (NEPA) and the spill, she will show how NEPA became one of the foundational documents for 21st century sustainability and resilience programs.
- Locally Grown Power: The First Non-Profit Solar Panel Assembly Factory in the World
Richard Haskell, Professor Emeritus, Harvey Mudd College; Peter Saeta, Professor, Harvey Mudd College; and Devon Hartman, CHERP, Inc.
Locally Grown Power (LGP) is a program of CHERP (Community Home Energy Retrofit Program) that aims to create an assembly plant for solar photovoltaic (PV) panels in Pomona, California, that is designed to be replicable in cities across the state. The primary mission of this non-profit, social enterprise is to install solar systems on the roofs of low-to-middle income families who are currently being left out of the ongoing energy revolution. Over 200 local workers will be trained to assemble, test, and install solar PV systems that incorporate newly patented technology.
The LGP program will be described in detail followed by Q&A and invitations to the audience to become involved. (45 minutes) A review of the patented idealPV panel-controlling strategy and electronics will follow with its own Q&A session. (30 minutes)

Single Workshop Track
- Human-Centered Design for Sustainability, Shannon Randolph (The Hive)
Learn human-centered design (HCD) tools to design locally suited interventions to persistent sustainability challenges. HCD can be used to reframe issues from the perspective of natural resource or energy users, and then to design interventions that meet their needs as they relate to sustainability issue. This tool can equally be applied to climate change, wildlife trade, government capacity building or any environmental problem. There are three main phases to the HCD process: (1) empathetic research and reframing of problem space from extreme users’ perspectives, (2) rapid prototyping and testing of solutions, and (3) iteration to design salient solutions based on user feedback. You will be provided with brief examples from international conservation work and will engage in a rapid experiential workshop on the human-centered design process.
- Sustainable Benefits of Drones, Warren Roberts (Claremont Colleges Library)
There are many benefits that drones have brought to the field of environment and sustainability. Learn the benefits of how UAV technology is applied from capturing imagery of large tracts of land to determining health of crops or perform runoff analysis to generating surfaces to quickly determine areas, slopes and aspects. We’ll cover the workflow in collecting imagery and surfaces from flight planning, accuracy, risk assessment & Data capture (sUAV) to data processing into GIS.
Duo Workshop Track
- Composting 101, Peter Staub (Pomona College Farm Manager)
Come join the farm manager from the Pomona College Organic Farm to learn the basics of composting. This will include a brief lecture on how composting actually works, stages of the process, and different methods of composting. Primarily, though the workshop will be a hands-on exercise in how to build and subsequently turn a compost pile. No previous experience or equipment required, just be ready to get a little dirty (and maybe a bit smelly)!
- Searching for a Green Career, Brad Tharpe (Pitzer College) and Paul Hardister (Harvey Mudd College)
Come learn a strategy for looking for jobs and internships, including resources specific to “green careers.” You will have the opportunity to create individualized action steps that you can take to explore or plan for a career in green or environmental fields!
Poster Session Descriptions
- CapSol: Off-Grid Lighting Solution for Rural Haiti
Tejus Rao, student, Harvey Mudd College
For the past couple summers and during the 2017-2019 school year, students working for Professor Yang have been developing low-cost solar-powered lighting for a rural Haitian village. Prof. Yang has a contact at UCI who has been working with this village for several years and has made a well and a school, among other things, there. He requested that we design a cheap, efficient, and robust solar-powered light that students and their families could use. One of the designs that was created at the end of last summer, which has since been improved and re-designed, employs a donated pill-bottle as the main housing for the electronics of the light. The design has been optimize to reduce cost and make the light easy to assemble by anyone regardless of skill level, including children and the villagers themselves. This design, though there have been a couple others with modifications to electronics, structure, and software, will serve as an educational tool for youth in the community, a job opportunity for rural workers in hopefully many places in Haiti, and a well-designed solar-powered lights that will hopefully brighten the students’ lives.
- NGO Corporate Partnerships
Rebecca Chung, REC Team Manager, Claremont McKenna College
Our presentation will examine the rationales and opportunities for mutually beneficial partnerships between from corporations, environmental NGOs, and government. Recognizing that alternatives to partnerships exist, the poster will explain the considerations that should guide whether a corporation or NGO should seek partnerships, what exchanges between corporations and NGOs could be mutually beneficial, what roles government agencies could play in fostering constructive partnerships, what the risks are in pursuing and undertaking partnerships, and how the arrangements can maximize the benefits while minimizing the risks.
- Intelligent Air Quality Sampling via Mobile Sensor Networks
Jacob Donenfeld, student, Harvey Mudd College
We optimized both Route planning and Surface mapping algorithms through a combination of modeling and field studies. The long term objective is to use the results of this work to create a network of autonomous vehicles for real time pollution monitoring throughout the Los Angeles megacity in order improve the spatial and temporal resolution of air quality measurements and to improve air quality predictions.
- A Novel Design for an Energy-Harvesting Fish Tracking System
Christopher Ferrarin, student, Harvey Mudd College & Richard Zhang, student, Harvey Mudd College
Existing technology for observing and tracking aquatic species is presently limited by the size, longevity, and complexity of active underwater tracking tags. This work describes a method of bypassing these limitations by establishing an acoustic communication link between an array of transducers on a boat at the surface of the ocean and a passive energy-harvesting tag underwater. Previous research on this system is expanded to establish an underwater acoustic power link between a transmitting piezoelectric tube on the boat end and a receiving resonant voltage booster on the fish end. Improved boat-end power amplification and fish side receive circuitry enable a consistent power link between the boat-side and the fish-side, and power down to the fish side has been characterized for a maximum of 4.5 micro-watts at a distance of 0.5 meters.
- Octocoral Species Identification and Distribution in the Gulf of Mexico
Katie Erickson, student, Harvey Mudd College
Deep water corals were affected by the 2010 Deepwater Horizon spill in the Gulf of Mexico; however, the limited knowledge on these corals and their ecology made it difficult to assess their condition after the spill. To be better equipped to understand and respond to the impact that future environmental disasters may have on these deep sea coral populations, researchers are assessing the connectivity of octocoral populations in the northern Gulf of Mexico. An important step in this process is obtaining accurate species identification for the coral samples used in the study. Using DNA barcoding of mitochondrial genes for the octocorals Paramuricea biscaya and Callogorgia delta, we were able to confirm the in situ identification of these coral samples, or identify samples as cryptic species. We determined the number of haplotypes for each species across their collection sites, and contributed vital information to an ongoing study of octocoral connectivity.
- Micro-Grid Systems to Provide Electricity and Clean Water to Rural India
William Cullen, REC Student Manager, Claremont McKenna College; Sustainable Development Policy and Finance Team, Roberts Environmental Center, Claremont McKenna College
India faces a unique triple challenge: meeting growing per capita energy demand, cutting pollution, and expanding energy access to rural areas. Decentralized renewable energy technology, where solar energy is connected to a small micro-grid system, can provide clean, affordable, and accessible energy and has the potential to empower communities, reduce pollution, and provide sustainable sources of income, especially women, in these rural areas. One model in particular, created and operated by a social enterprise in Delhi, India called Grassroots and Rural Innovative Development (G.R.I.D.) uses decentralized renewable energy technology to create solar-based employment opportunities for women in rural areas. Projects include solar-based Reverse Osmosis/ Ultraviolet water purification plants and micro-grids for rural electrification. Our poster will demonstrate the technical components as well as the socio-economic and environmental benefits.

Morning Presentation Descriptions
- Empowering Undergraduates for Sustainability Research and Education in Chemistry
David A. Vosburg, associate professor | Department of Chemistry, Harvey Mudd CollegeVosburg will describe projects that engage undergraduates with sustainability concepts in the classroom, the teaching laboratory and the research laboratory. Examples include comparisons of the greenness of industrial or academic syntheses of pharmaceutical drugs, several new laboratory experiments and biomimetic syntheses of medicinal natural products. Both published and unpublished work will be presented.
- POCACITO– Post-Carbon Cities of Tomorrow: Innovation Councils for Participatory Sustainability
Max Gruenig, senior fellow | Ecologic Institute, Washington, D.C.Post-Carbon Cities of Tomorrow creates local Innovation Councils in six U.S. cities (Denver, Detroit, Houston, Las Vegas, Memphis and Minneapolis) in order to develop post-carbon visions and solutions in a participatory exchange with sustainability leaders from European cities.
In each U.S. city, world cafe-style workshops unite diverse participants, including city officials, urban planners, researchers, non-governmental organizations, community-based organizations and citizens, maximizing learning and implementation potential. The POCACITO approach is open-ended and fluid. It does not prescribe specific outcomes. Thus, the results are highly localized and situation-specific. Surprisingly, the outcomes of the Innovation Councils are comparable and allow conversation and discussion between the different U.S. cities along the major topical axes of building sustainable communities, sustainable water management, and sustainable mobility and accessibility.
The insider-outsider perspective and co-creation approach in POCACITO has proven its ability to advance the sustainability discussion at the local level and beyond.
- Environmental Justice and Water Policy During a Drought Event: Community Fragility and Cutback Assignments
Heather Campbell, Trish Miller and Kristoffer Wikstrom | Claremont Graduate University; University of MontanaIn an effort to curb water use in drought-stricken California, the state recently implemented reduction measures whereby each water district is required to reduce water consumption. While there is no doubt that Californians must limit their water use, questions remain regarding the fairness of the mandated cutback assignments. De jure, water districts that previously consumed larger quantities of water are required to reduce consumption by a larger assigned percentage than communities that originally consumed less water. But do these cutback assignments disproportionately affect fragile communities or racial and ethnic minorities? Using GIS matching techniques and regression analysis, we analyze the amount of water each district is allowed to use (after mandated reduction) and variables found in the CalEnviroScreen 2.0—an index of community fragility—to see if these water reductions are prone to the same environmental injustice issues that have been seen in other research.
- Route 66 Pathways Project
John N. Bohn (AIA, LEED AP) and Benjamin Hackenberger | Southern California Institute of Architecture and Pomona CollegeOver the first half of the second millennium, Japanese artisans used Emaki scrolls to document important events that unfold across multiple and technically complex spaces in a single continuous drawing. In preparation for the 100th anniversary of the completion of Route 66, The Pathway Project is an Emaki-inspired live drawing of this “great American pathway”—a uniquely American blend of myth and reality that underpins the development of the American West. As an experiment in visual environmental and cultural representation, the Project aims to unfurl across 78 9-foot panels focusing on architecture, human occupation, parkland, cities, suburban landscape, history and hardscape of the past and present, adapting and developing emerging technologies of architectural representation along the way. The story of this tool for working with cultural space reveals potential problems and solutions for the design of the built environment.
- LADI and the Trawl: A Low-cost, DIY Surface Trawl for Marine Microplastics Monitoring and the Promotion of Citizen Science
Coco Coyle ’17 (engineering) | Harvey Mudd College and Civic Lab for Environmental Action Research (CLEAR), Memorial University of Newfoundland, CanadaMore than 5.25 trillion pieces of plastic clutter the ocean surface, and over 92 percent of these are smaller than a grain of rice. These microplastics absorb toxic chemicals, are consumed by small and large animals, and are wreaking havoc on marine ecosystems. Monitoring marine plastics is the first step in developing effective solutions: clean-up technologies cannot compete with the scale of the problem, and current monitoring tools are expensive and limited to experts.
In the summer of 2016, Coyle led the design, implementation and validation of a surface trawl to be used for marine plastics monitoring. This trawl, the Low-tech Aquatic Debris Instrument (LADI), intends to promote collaboration between experts and citizens in the effort to understand of microplastic contamination, by being exceptionally accessible, sharable and easy to construct. This presentation discusses the project as an example of building equity, justice and citizen science into your scientific process.

Afternoon Poster Session Descriptions
- Transcriptonomics of bleaching in the Alcyonacean octocoral Sympodium sp.
Jennifer Havens ’18 (mathematics) | Harvey Mudd CollegeCoral bleaching is a major threat to octocorals (soft corals and sea fans), which represent up to half of the primary substrate available on many shallow-water reefs. Corals are extremely sensitive to environmental conditions, such as rising sea temperatures associated with global climate change. Environmental stressors can lead to coral bleaching, a potentially lethal breakdown of the relationship between corals and their photosynthetic endosymbionts. Previous research has found that the impact of bleaching varies among members of both the scleractinians and the octocorals, thus it is important to understand the different mechanisms. The holobiont transcriptome, sampled at key time points in the bleaching process, is used to characterize the bleaching of the Alcyonacean octocoral Sympodium sp. The experimental time points showed significantly different transcription. The biological processes of genes differentially expressed during bleaching appear consistent with scleractinians and Aiptasia bleaching responses.
- Formation of Secondary Brown Carbon in the Multiphase Simulation Chamber (CESAM) Through Aldehyde and Anime Initiated Maillard Reactions
Lelia Hawkins, Barbara Stokes Dewey Assistant Professor of Chemistry, Jason Casar ’18, Elyse Pennington ’17 and Hannah Welsh ’17 | Harvey Mudd CollegeLaboratory measurements suggest that secondary organic compounds-with absorbance spectra characteristic of atmospheric humic-like substances (HULIS)-can form in aerosol and cloud water. Atmospheric HULIS have features such as broad, wavelength-dependent absorbance tailing into the visible region, highly functionalized and high molecular weight character, and appreciable organic nitrogen. In this work, we simulate the formation and evaporation of clouds in the presence of aldehydes and amines using a multiphase simulation chamber at the University of Paris-Est Creteil, France. Particle absorbance was determined with a Particle Into Liquid Sampler-Capillary Waveguide system and normalized to integrated particle mass measured with a scanning mobility particle sizer. Measurements indicate that browning occurs prior to cloud formation in the presence of methylamine and methylglyoxal but increases following formation. Further, artificial sunlight appears to bleach the products, reducing aerosol absorbance. A second round of experiments conducted in summer 2016 provide more chemical detail and reproducibility of preliminary measurements.
- Active Transportation: A Mobile App for a Walking Bus at Claremont
Julie Medero, assistant professor of computer science, and Yiqing Cai ’17 | Harvey Mudd CollegeActive transportation app is dedicated to address the concern about heavy traffic around elementary schools. Parents drive their kids to school mainly because of safety issues. The app offers an easy way to manage walking school buses by providing a variety of tools including checklists, real-time map tracking, easy notification and more. This mobile app can encourage more parents and schools choose walking school bus and thus help resolving the traffic issues near elementary schools. Reduced traffic means a safer and cleaner environment for kids in Claremont.
- Combinatorial photoconductivity mapping of thin film semiconductors for photovoltaics
Olivia Schneble ’17 (engineering), Angela Fioretti, Adele Tamboli ’04 (physics), Andriy Zakutayev | Harvey Mudd College, National Renewable Energy Laboratory (Golden, CO) and Colorado School of Mines (Golden, CO)The Rapid Development of Photovoltaic Materials project at the National Renewable Energy Laboratory (NREL) develops exploratory methods of fabricating and characterizing thin film earth-abundant semiconductors that could be used in solar panels. As part of this project, an existing four-point probe conductivity measurement system was upgraded to measure photoconductivity in a mapping style. Photoconductivity under various wavelengths gives information about minority charge carrier dynamics and light absorption in a thin film sample, which allows researchers to approximate its performance in a photovoltaic device before fabricating the entire cell. Four LED sources were attached to the probe setup and the existing LabView control was adapted to produce sheet resistance maps across a two-dimensional surface under each light. Igor Pro procedures for calculating conductivity were also adapted. The system was tested by measuring several absorbing samples, some of which showed significantly reduced sheet resistance (indicating increased conductivity) under illumination.
- Automated Aerial Flower Species Classification in Southern California

- Active Transportation
Julie Medero, assistant professor of computer science, and Erin McCarthy SCR ’17 | Harvey Mudd College and Scripps CollegeDuring drop-off and pick-up times, traffic around schools results in long waits for parents and numerous cars emitting pollutants. Parents say they are hesitant to let their children walk to school because of safety concerns. To make it easier for families to identify safe walking routes, schools in California are required to have maps that show stop lights, cross walks, intersections and suggested routes to walk or bike to school. These maps often do not exist because of liability concerns. This project aims to give schools and parents tools to generate maps showing preferred walking routes using existing tools like the Google Maps API and Open Street Maps. We generate two types of visualizations: isochrone maps, which show the area that is within a certain distance of the school; and walking directions, which show suggested paths to take to school from anywhere within the walk radius of a school.
- Metal Retention in a Pomona College Bioswale
Zachary Evans ’18 (chemistry) | Harvey Mudd CollegeBioswales are an up-and-coming type of green infrastructure that slow storm water runoff and sequester heavy metals. This study focuses on a bioswale at Pomona College to characterize the sequestration of metals in soils and uptake into plants. Principle component analysis reveals this bioswale effectively sequesters metals because the largest variance in surface soil samples occurs between three successive water catchment basins. This trend is confirmed by statistically significant (P<0.1) decreases in concentration of anthropomorphic metals such as Zn, Pb, Co, Mn and Cu along the bioswale. In addition, initial depth studies reveal little effect on metal concentrations in soil, uptake of metals by local Carex vernacula, Juncus patens, Epilobium ciliatum subsp. ciliatum, and introduced Phoenix dactylifera does not appear significant, and sequential metal extractions reveal most metals reside in the organic fraction of soil.
- Residential Buildings Benchmarking in Los Angeles County
Anthony Seto ’19 (engineering) and Justin Lauw ’18 (engineering) | Harvey Mudd College, Res-IntelRes-Intel, a software firm located in Claremont, develops software solutions to improve the performance of residential and commercial buildings to reduce global warming pollution and reduce occupants’ spending on utility bills. Part of the solution involves benchmarking of buildings in the EPA’s Energy Star Portfolio Manager. In order to allow the mass-scale benchmarking of buildings, EPA has developed a data-exchange web service for Energy Star Portfolio Manager. This summer, we helped develop a data-exchange interface exchange that sends building consumption data and receives EnergyStar’s benchmarking score. In conjunction with building benchmarks, we used Esri’s ArcGIS software to clean and prepare Los Angeles County parcel data. This can then be used to calculate statistical data regarding multifamily residential buildings.
- Updates to the Nitrogen Cycle
Dr. Matthew Seaman P16, FACEP, ABIMRepresentations of the nitrogen cycle, up to now, have focused on the flow of nitrogen at the soil surface, within soils and within air. Only rarely do representations of the nitrogen cycle acknowledge leaching of nitrates downward through sediments and rocks before entering the subsurface aquifer. Toxic levels of nitrates within subsurface aquifers is currently ubiquitous. Evidence indicates that ingestion of groundwater nitrates, with conversion to nitrites, cause impaired methylation of DNA leading to neural tube birth defects in the human population. In addition, nitrate interaction with sediments and rocks result in the change of inert, mineralized uranium to dissolved uranium within subsurface aquifers. In the High Plains (USA) dissolved uranium levels are 80-fold the toxic limit and in the Central Valley aquifer (California) dissolved uranium levels are roughly 190-fold the toxic limit. Ingestion of uranium is associated with cancer and birth defects. Long-term ingestion of uranium-contaminated drinking water now represents an emerging public health concern. The continued use of the subsurface aquifer for irrigation of crops also represents a significant threat to food-safety. Pump-and-treat facilities, applied at a large scale, may be necessary to mitigate the adverse impact of nitrates and dissolved uranium on human health.
- Energy Audit for Mt. San Antonio Gardens
Anthony Burre CMC ’19, Lauren D’Souza CMC ’18, Lillian Liang HMC ’18, Jenna Perelman SCR ’16 and Nova Quaoser CMC ’19 | Claremont McKenna College, Harvey Mudd College and Scripps CollegeA team of students from the Roberts Environmental Center worked on an energy audit for the Mt. San Antonio Gardens Retirement Community. The project was advised by Sam Tanenbaum, professor emeritus of engineering at Harvey Mudd College and Gardens resident. The team studied financial and environmental effects of updating AC units and evaluated nine proposals for solar array installations at Gardens facilities. At the conclusion of the study, the team recommended that the Gardens update AC units to SEER 14 and accept SunPower’s proposal; their analyses will inform the Gardens’ energy conservation plan, which is currently in its first phase.
- Bio-Inspired Dehalogenation Reaction
Rilke Griffin, Christopher Ye, and Katherine Van Heuvelen | Harvey Mudd CollegeCarcinogenic chlorinated hydrocarbons such as perchloroethylene (PCE) and trichloroethylene (TCE) are pollutants that have been found in groundwater throughout the United States. These halogenated compounds can be metabolized by enzymes called reductive dehalogenases that decompose PCE and TCE under environmentally-friendly conditions. The reductive dehalogenases use a cobalt-containing active site, but the fundamental chemistry behind this important reaction is poorly understood. We investigated this reaction through the synthesis of bio-inspired molecular model compounds that resemble the enzyme active site and reacted these models with PCE and TCE. Reactions were monitored using UV-visible spectroscopy and gas chromatography-mass spectrometry. Our results show that our molecular models successfully carry out the first dechlorination step necessary to degrade PCE.

Skill Building Workshops
- Design and Decomposition: A Composting Workshop
Aaron Burton Cyr-Mutty, farm manager, Pomona CollegeWhen people think design, steaming piles of compost generally don’t jump to mind, but green waste management is one of the many areas where intelligent design can create opportunities for sustainable development, especially given the enormous amount of food waste in our current agricultural system. Composting, however, isn’t simply throwing food scraps into a pile, but requires a careful balance of inputs to support the whole ecology of bacteria, fungi, insects and worms. Come join Pomona College’s farm manager to design the perfect pile and talk about how composting can be a part of sustainable design at a personal and institutional level.
