“The way we cool our buildings right now is totally wrong,” said Indian architect Monish Siripurapu in a video produced the United Nations' Environment program. The words are bleak, but arguably true; the electricity and hydrofluorocarbons most modern cooling systems demand ironically warm the planet overall while they cool our conditioned spaces. On top of that, with global temperatures rising and worldwide populations growing, demands for cooling are only increasing. More eco-friendly options are urgently needed, and Siripurapu’s New Delhi–based firm Ant Studio has proposed an affordable, scalable, sustainable, and aesthetically appealing solution to the problem of air conditioning. Ant Studio’s mission is to combine “art, nature, and technology,” and its temperature-regulating solution is designed to be as much an art installation as a cooling system. The Beehive, as the system's first iteration is called, was built to ameliorate high-temperature conditions for laborers at the Noida, Uttar Pradesh–based manufacturer Deki Electronics, where generators and other equipment output their own heat, adding to high outdoor temperatures. The Beehive is part of a larger exploration by the firm that leverages terracotta tubes and water as part of a low-energy cooling system. The Beehive, so-named for its honeycomb-like structure, follows an Indian tradition of using earthenware to cool water. “Traditional architecture has so much wisdom,” said Siripurapu. The ancient process has been wholly modernized, with tools such as computational fluid dynamics modeling, as well as the addition of low-energy water pumps and, if needed, electric fans. But instead of using fans with the Beehive installation, Ant Studio’s cooling device was placed right in front of the exhaust vents of the diesel generator near where workers at the factory were active. This was able to drop the “scorching” air being expelled from the generator from 122 degrees Fahrenheit to 97 degrees Fahrenheit, while lowering the overall temperature in the area and reportedly consuming 40 percent less energy than other cooling systems, not to mention using no refrigerants. The cooling system consists of arrays of open terracotta cylindrical cones (designed in such a way to maximize surface area and fired at “mid-level” temperatures to maintain the clay’s ability to absorb moisture from the air) over which water is poured. The water, which adheres to the clay, naturally lowers in temperature due to evaporative cooling, which in turn cools the air passing through the tubes. The water can be recycled throughout the system, requiring only infrequent topping off, and biofilms of microalgae that grow on the clay surfaces can actually aid in air purification, according to the firm. Further, as explained in an informational video from the firm, “all materials are recyclable, reusable, or biodegradable.” While the Beehive at Dika Electronics took on a particular nature-inspired form, the system can be designed in all manner of shapes and sizes, and is inherently modular, making fabrication and assembling on-site simple. The overall hope with the project is to devise a system that is “functional and visually appealing at the same time.” Ant Studio views the cooling systems as a work of sculpture as much as a functional tool. The terracotta cooling systems also could have broader social impact. Besides being a cheap, energy-efficient way to cool factories and public spaces, the craft required to manufacture the tubes creates local employment and skill-building opportunities. It also keeps alive traditional manufacturing techniques that provide a unique, hand-hewn character that industrial cooling systems certainly lack. The clay-based materials also mean a net reduction in embodied energy for these cooling systems. Ant Studio has also proposed a smaller system which they’re calling ETHER, a cooling device for personal use and small spaces that resembles something like a cross between a Dyson fan and an ancient artifact. Ant Studio’s cooling projects were one of the twelve winners of the United Nations’ Asia-Pacific Low Carbon Lifestyles Challenge and have been nominated for the Clean Energy Challenge from What Design Can Do, a “platform” and series of global conferences on design. Nominated teams are given the “opportunity to improve their project” with the final winners to be announced on March 6.

What does climate change sound like? Working with the Natural Resources Defense Council (NRDC), Chicago-based architectural installation artists Luftwerk hope to answer this question for pedestrians along the Chicago River. White Wanderer will be a large scale visual and audio installation that will bring the sounds of Antartica's melting and moving ice to 2 N. Riverside Plaza in the West Loop. The 17,000-square-foot Larsen C ice shelf has been watched by scientists for the past 20 years as warming seas threatened to break it apart. This past July, 2,300 square miles of the ice shelf broke off Antarctica and floated into the Wendell Sea. It is this new massive iceberg that is the inspiration of White Wanderer. The installation will include sounds rarely heard by humans. An eerie soundtrack of melting and shifting glaciers will fill the plaza. On the front of the historic 1929 Holabird & Root–designed Riverside Plaza building, the artists will install a graphic of the 120-mile rift formed by the ice drifting away from Antarctica. “White Wanderer allows people to hear and see how climate change is impacting our world right now, and contemplate how the consequences of climate change—like flooding and sea level rise—will dramatically change the way our lives will be lived in the not-too-distant future,” said Rob Moore, senior water policy expert at the NRDC, in a press release. To realize the project, the team has launched a Kickstarter campaign to raise $17,000. Rewards include downloads of the icy soundtrack, renderings of the rift, and a limited edition vinyl album. If funding goals are reached, the installation will be on show from September 7 through October 1, 2017. The show will also be seen on Navy Pier as part of EXPO Chicago and the Chicago Architecture Biennial from September 13 through September 17, 2017. Petra Bachmaier of Luftwerk said in a press release, “By bringing this remote Antarctic place to an urban center like Chicago, we hope to instill a sense of wonder of the natural world to inspire people to take action to protect these extraordinary places.”
To avoid total inundation and more of those hot, sticky summer days, New York City is trying hard to forestall the impact of global warming. While tackling coastal resiliency, the city is turning its focus to buildings, the source of 75 percent of the city's greenhouse gas emissions. To address the issue, last month Mayor Bill de Blasio unveiled the NYC Retrofit Accelerator, a program that will provide consulting and support, for free, to building owners who would like to conserve electricity and water, and upgrade to clean energy systems. Officials hope that, in addition to slashing emissions, energy retrofits will reduce building owner's operating costs. This program builds on the success of 2012's NYC Clean Heat, a component of PlaNYC that was introduced by the Bloomberg administration. The program works towards goals outlined in 2014's One City: Built to Last, which set a goal of reducing emissions 80 percent by 2050. By 2025, officials hope the accelerator will serve over 1,000 buildings per year, and reduce greenhouse gas emissions by one million metric tons each year. This would save property owners $350 million per year in utility costs. The biggest climate offenders are buildings that burn heavy heating oil. Consequently, the program primarily serves these buildings, as well as any building that participates in a Housing Development Corporation (HDC) or a Department of Housing Preservation and Development (HPD) program. Efficiency experts at the Retrofit Accelerator will help owners select appropriate retrofits, conduct energy audits, apply for related permits, get financing, apply for tax credits, train maintenance staff, measure energy efficiency over time, and comply with local laws. Interested property owners can visit the Retrofit Accelerator's website or call 311 to determine their eligibility.
A collection of grain silos and railroad tracks next to the University of Minnesota's Minneapolis campus is set to become a “living laboratory” for climate resilience, according to its designers and allies in city and regional government. Prospect North would be a mixed-use development with a “science park,” library, business incubators and new industrial spaces all plugged into a local power grid dedicated to the eight-acre development. Sandwiched between Highway 280 and the TCF Bank Stadium northeast, the project benefits from the recently completed Green Line—an 11-mile line that connects the Twin Cities by light rail for the first time in decades. “We saw that development was going to happen here,” Richard Gilyard, an architect working on the plan, told Next City's Rachel Dovey. So, Gilyard continued, he and other residents of the nearby Prospect Park neighborhood rallied support for a new kind of development from the City of Minneapolis, Hennepin County, the Public Housing Authority, the Mississippi Watershed Management Organization and the University of Minnesota, and other local players. Gilyard and others saw the former industrial area as a proving ground for afuturistic, climate resilient neighborhood-scale technologies. “You don’t have this in Cambridge or Berkeley,” said Tom Fisher, dean of the University of Minnesota College of Design, in a brochure for the project. “It’s a great opportunity for the Twin Cities to show what a 21st Century city could be like. How do we live? How do we educate ourselves? How do we live sustainably?” Prospect Park 2020 is still in planning phases. But its partnership with local agencies is rooted in previous climate action in the Twin Cities. Citing data from the U.S. Global Change Research Program, the city's climate action plan warns Minneapolis could see a substantial increase in heavy precipitation due to climate change, as well as higher average temperatures. That could push already aging infrastructure past its breaking point. The plan also calls for Minneapolis to reduce energy use by 17 percent by 2025, in part by generating 10 percent of its electricity from “local, renewable sources.”
A web-like dome in Saginaw, Michigan changes colors to reflect the level of carbon dioxide in the air. Solar-powered LED lights connected to an onsite CO2 monitor illuminate the structure’s fibers in timed patterns to create the appearance of an organic response. On display in Saginaw’s First Merritt Park through October 31, the installation is part of the Great Lakes Bay Region’s “Art and Sol” celebration of art, culture, and science. The structure of Loop.pH’s SOL Dome was inspired by molecular biology. SOL Dome, eight meters in diameter, was constructed on site by volunteers over three days.
Hang up those snowshoes. The NYC Parks Department has officially canceled this year's Winter Jam, an annual event that invites New Yorkers to come try out an array of snow sports in Brooklyn's Prospect Park. What gives? Not only is there no snow in the forecast for the planned February 4 date, but average temperatures are too high for the city to even fake it. "It is simply too warm to make snow, and the long-range weather forecasts and current ground temperatures make it extremely unlikely that snow could be made," said Parks Commissioner Adrian Benepe.
