A new study led by sustainability scientist Matei Georgescu reveals some of the dynamics at play as one region of the country, the Central Valley of California, braces for substantial population growth and all it entails. The study, based on computer simulations of rural to urban land conversion, shows that as areas of California grow and develop, the resulting built environment could generate additional heat.
Georgescu used ensemble-based simulations employing EPA projections of urban growth to assess urban expansion climate effects by the year 2100 in the Central Valley. He first assessed the resulting rise in regional temperatures and then explored several temperature mitigating strategies for buildings: cool roofs, green roofs and hybrid approaches. He found that as the state deploys temperature-mitigating technologies, there are secondary effects that appear to take place, such as less daytime air turbulence, which could lead to higher concentrations of pollutants.
But the urban heat island effect can be mitigated using new technologies and the latest in sustainable design techniques, said Georgescu, whose “Challenges associated with adaptation to future urban expansion” appears in the April 1 issue of the Journal of Climate. Finding the right combinations of technologies and techniques will be key.

Arizona State University computer scientist Carole-Jean Wu is gaining attention for her work to improve the energy efficiency of both large- and small-scale computing nodes, encompassing everything from desktop processors, smartphones and other mobile devices to business-scale data centers.
Wu’s research focuses on designs for chip-multiprocessors and heterogeneous computing systems, energy-efficient smartphone architecture and architectural energy harvesting techniques for modern computing nodes. Rather than allowing superfluous heat generated by devices to reduce performance speed, Wu decided to harvest it with a thermoelectric generator, which converts heat to electricity using a phenomenon called the Seebeck effect.
Wu’s paper, “Architectural Thermal Energy Harvesting Opportunities for Sustainable Computing,” recently received the Best of Computer Architecture Letters (CAL) award.

The story goes that when beetles were discovered in the eaves of the great hall at New College in Oxford, everyone began wondering where they could possibly find replacements for the gigantic timbers that had held up the roof for hundreds of years. They needed oak trees almost as old as the building itself. As it turned out the founders of the college had planted oaks expressly for the purpose of repairing structures, with university foresters protecting them over generations. The great hall was completed in the late 1300s, and they were building something that they intended to last functionally forever.
Today it seems like the expected lifespan of a building is getting shorter, not longer. More alarmingly, our perception of time seems to be narrowing—we forget our history just as readily as we ignore the future.

Using a three-year $600,000 grant from the Water Sustainability and Climate program, ASU engineers and sustainability scientists Mikhail Chester and Thomas Seager are leading a project that will provide a guide to boosting the resilience of infrastructure systems against potential threats posed by climatic changes.
Seager will work on developing one of the key methods the project team hopes will encourage foresight in policymaking and planning for these infrastructure networks. Using Arizona as a case study, Seager will devise a game-based learning platform – specifically a computer game – to educate leaders about possible future infrastructure vulnerability issues and how to approach the task of assessing what can be done to deal with them sooner rather than later.
The work based at ASU’s Sustainable Urban Systems Lab, which is directed by Chester, will focus primarily on desert regions because they are especially vulnerable to environmental impacts brought on by climate-related factors.

In the latest installment of the “Sustainable Cities” series, Senior Sustainability Scientist Nancy Grimm discusses common misconceptions about ecologists and nature. She presents the idea of untouched wilderness as an example.
“We’ve recognized that there really aren’t such places, or are very few such places, left on Earth,” says Grimm, an ecologist herself who has worked in the field for more than 30 years.
Grimm is also the director of Central Arizona-Phoenix Long-Term Ecological Research, a project launched in 1997. CAP LTER is one of 26 LTER sites throughout the United States. Based at ASU, it is one of only two sites that examine urban ecosystems. Specifically, the Phoenix site answers questions about ecosystem services – benefits provided to people by the environment or wildlife – and studies how humans interact with nature in their cities.

In an effort to improve prospects for generations to come, a group of ASU scholars in the emerging discipline of environmental humanities is addressing humanity’s struggle to think in the long term. The team, which includes sustainability scholars Sally Kitch and Joni Adamson, approaches its work using a combination of humanistic scholarship and scientific research. Their aim is long-term, human-centered solutions that truly transform the way we live and think.
“We have technological advances that could go a long way to solving some of these problems. But we aren’t implementing them,” says Kitch. “We don’t have the political or social will to make the kinds of dramatic changes in our values, in our sense of comfort and well-being in the world, that are really required if we’re going to get off of the fossil fuel gravy train that shapes our current political and economic systems.”
Kitch, Adamson and others are working toward their goal through activities like leadership in the international Humanities for the Environment project, which houses its North American Observatory Branch at ASU.

ASU researchers are exploring new energy storage technology that could give the lithium-ion battery an even longer life. By combining a high-performance silicon electrode architecture with a room temperature ionic liquid electrolyte containing the new bis-fluorosulfonylamide anion, the researchers establish a highly energy-dense lithium-ion cell with an impressively long cycling life. In fact, it maintains greater than 75 percent capacity over 500 charge/discharge cycles with almost no wasted electrons.
“This study brings home the fact that energy storage technology still has a lot of room to run, with new technological changes coming at a fast pace,” says Dan Buttry, professor and chair of ASU’s Department of Chemistry and Biochemistry. “This is important when considering areas where storage is important, such as grid storage and electric vehicles.”

In anticipation of a Future Tense event on technology and the future taking place in Washington, D.C., Senior Sustainability Scientist Sethuraman Panchanathan explores the subject in Slate magazine. His article, titled “The best adaptive technologies are designed by, not for, people with disabilities,” illustrates this point using ASU graduate David Hayden as an example. Hayden, who is visually impaired, used his disability to develop an assistive tablet called the Note-Taker – a technology that his sighted peers were also eager to use.
“Truly revolutionary technologies require engagement with users throughout the design and development process. While it’s helpful to get feedback and ideas from focus groups on users’ needs, short sessions don’t give us a full understanding of the challenges and opportunities in developing assistive technology solutions,” writes Panchanathan. “It is imperative that people with disabilities play a leading role in envisioning, conceptualizing, developing, implementing, deploying, testing, and validating potential solutions, tools, and technologies.”
In a November 2014 Thought Leader Series Piece, Ray Jensen made a similar point about the importance of including disabled persons, particularly from a sustainability standpoint.

A new poll, conducted by ASU’s Morrison Institute for Public Policy and the Walter Cronkite School of Journalism and Mass Communication, articulates the top two priorities among Arizona residents: education and water.
The inaugural Morrison-Cronkite Quarterly Poll surveyed 754 Arizonan adults statewide to assess opinions on a variety of issues, from law enforcement to arts and culture. Among the 11 issues offered to respondents, “maintaining adequate water and water quality” ranks at that same level of importance (87 percent) as education.
“It’s apparent that the importance of ensuring an adequate and quality water supply for Arizona’s varied interests figures prominently on Arizonans’ radar,” said David Daugherty, associate director of Morrison Institute and director of the poll. “This is a complex and dynamic issue, but clearly one that Arizonans understand as a priority that needs to be thoroughly examined and addressed.”

Addressing a crowd of nearly 2,000 people in ASU’s Gammage Auditorium, renowned journalist and author Thomas Friedman contended that maintaining our freedom is going to require a major value adjustment. The Pulitzer Prize winner, who visited ASU on Feb. 26, explained that society has been built on situational values, which have led to unhealthy interdependencies and our current climate concerns.
Friedman went on to explain that our freedom now relies on building healthy interdependencies that mirror those found in nature, and are based on sustainable values. The impactful talk – titled “Sustainability as Freedom” – marked the first of this year’s Wrigley Lecture Series and was made possible with the generous support of sustainability visionary Julie Ann Wrigley.

Note: March 3 marks the launch of ASU’s new Biomimicry Center, established in partnership with Montana-based Biomimicry 3.8, and co-directed by Prasad Boradkar. In this essay, Boradkar describes how biomimicry can help us create solutions to address our problems in sustainable ways.
A short five-minute walk takes me from my suburban home in south Phoenix to the Sonoran Desert, from the highly standardized and manufactured human-made world into the somewhat wild and undomesticated natural world.
Satellite views show stark differences between the two landscapes: rectilinear, hard lines divide the land inhabited by people, while meandering, unrestrained territories mark the land inhabited by all other creatures. We have, by design, created in contrast to the natural world, an artificial world of products, buildings and cities.
Philosopher Richard Buchanan describes design as “conception and planning of the artificial.” Using these processes of planning, we have created everything from tiny paperclips to enormous jet aircraft, from the smallest dwellings to the largest metropolises. And though these things are made of such materials of human creation as chrome-plated steel, aluminum and reinforced concrete, they are all ultimately extracted from the natural world. From the natural emerges the artificial.
