Overview

Breaking News: The Submission Deadline for the Cooling Solutions Challenge is extended to February 24, 2022!

Extreme heat is a silent killer, and according to the Centers for Disease Control and Prevention (CDC) is the nation’s leading cause of weather-related deaths. Protecting the public from heat-related illness and death during extreme heat events or in connection with other disasters is an important part of disaster preparedness and resilience. This is a crucial part of the Department of Homeland Security's (DHS) mission, and we need your help.

Contestants now have until February 24, 2022 to enter the Cooling Solutions Challenge and compete! We extended that date to give you plenty of time to submit your entry for a great solution to help cool a first responder, someone in your family, someone who is displaced because of power outage, or yourself! Submitting an entry is simple, see the "How to Enter a Submission" section for the submission instructions. The total prize pool is $195,000. Finalists will receive $5,000 each and automatically advance to the next round of judging with a chance of winning additional money. The grand prize is $50,000 and the runner-up will receive $20,000. We plan to announce the Finalists in March 2022 and the Prize Winners in May 2022 (dates are subject to change).

This Challenge is looking for innovative climate-friendly cooling solutions that can provide people in public and residential areas with access to technologies or ways to keep them cool during extreme heat conditions. Your solution should be eco-friendly and energy efficient, while being cost effective, scalable, durable, and also allow for alternate power sources. These features will make the cooling solutions well suited to reduce extreme heat risk during or after disasters when there is a power outage.

The Challenge is in four areas and is designed to help first responders, individuals, households and displaced or homeless populations. The Challenge is to propose a solution, that during heat events, would help those at the greatest risk of heat-related illness including infants and young children; people 65 years of age or older; people with illnesses or chronic health conditions; and homeless or displaced populations. In addition, this Challenge includes help for First responders or those required to work outdoors in support of community lifelines who are at risk for heat-related illness or require solutions to support encounters with heat-related illness.

This Challenge is part of the DHS’s effort to implement a proactive approach to climate change adaptation and resilience. This will be the first in a series of Challenges to address hazards posed by extreme weather due to climate change.

BACKGROUND
Promoting national resilience against the many threats associated with climate change, including extreme heat, is a DHS priority. According to the Centers for Disease Control and Prevention (CDC), the National Oceanic and Atmospheric Administration (NOAA), and the Environmental Protection Agency (EPA), extreme heat events have become more common across the United States in recent decades and are expected to become more common, more severe, and longer lasting as global temperatures continue to rise.

Extreme heat events and their effects significantly impact the United States. Extreme heat events are one of the leading causes of weather-related deaths in the United States, and a reason for many emergency departments visits and hospital stays. For example, record-breaking heat indexes in the Pacific Northwest in June 2021 caused more than 2,500 people to seek emergency department treatment for heat-related illness. In addition to causing extreme heat events, rising global temperatures produce extreme weather conducive to wildfires, flooding, and hurricanes, and that extreme weather can have large cascading effects of extended power outages coupled with high temperatures. This is causing large populations in communities across the country to be more vulnerable to heat-related illness. In the wake of the extended power outages caused by Hurricane Ida, for example, Louisiana has recorded several heat-related deaths.

There are some simple safety measures that people can take to protect themselves from heat-related illnesses or death, including avoiding unnecessary sun exposure, avoiding unnecessary hard work or activities outdoors, drinking water often, wearing light and loose-fitting clothing, and staying in an air-conditioned area during the hottest hours of the day. However, many Americans who experience extreme heat events lack access to conventional air conditioning. Solutions are needed to protect them, and to do so in an energy-efficient, user-friendly, and cost-effective way.

Overall, the judges will consider how user-friendly (easy-to-install or retro-fit and easy-to-use) and cost effective the solution is, and how well it meets the judging criteria.
We will choose Stage 1 Finalists based on how well the proposed solution(s) addresses the cooling problem and “Use Cases” including:

  • How well does the submission address the problem and criteria? Explain how your solution is applicability to the “Use Case(s)”. In other words, how would your solutions be used by First Responders, for Personal Use, by a Household, and in Indoor/outdoor venues accessible to homeless or displaced populations in public settings?
  • How is your solution unique?
  • How will your solution benefit those in the “Use Cases”?
  • If it you are submitting a technology, wow has that technology been used and validated
  • Are there potential benefits or tradeoffs?
  • And what is your business model or financial plans?


Stage 2 will be judged on the following criteria:

  • All the criteria indicated in Stage 1
  • Cooling capacity – The solution must achieve a cooling temperature within 10% variance of difference between the dry and wet bulb temperature of 35 degrees Celsius (for both indoor and outdoor scenarios). Ability to sustain the reduced temperature for 95% of the time that the temperature remains at 35 degrees Celsius during a 6-hour test scenario.
  • Energy usage – Demonstrate 35-50% reduction in energy consumption compared to a traditional Air Conditioning (A/C) cooling baseline unit.
  • Water consumption – Demonstrate 25-50% reduced water consumption compared to a traditional A/C cooling baseline unit, as applicable.

ANNOUNCING THE WINNERS OF THE COOLING SOLUTIONS CHALLENGE!

The U.S. Department of Homeland Security (DHS) announced the winners of the Cooling Solutions Challenge prize competition. The winners were each awarded funding, which totaled $195,000, for their innovative and creative ideas that sought climate-friendly cooling solutions to protect people in extreme heat conditions. In September 2021, DHS Secretary Alejandro N. Mayorkas, announced a new series of prize competitions focused on strengthening nationwide resilience to climate change.

The Cooling Solutions Challenge was designed to find groundbreaking solutions to protect the public against extreme heat, the nation’s leading cause of weather-related deaths. The challenge sought innovative ideas to help first responders, individuals, households, or displaced populations keep cool during extreme heat events, which have become more common across the United States with increasing frequency, intensity, and duration.
“Extreme heat is the leading cause of weather-related deaths in the country, often hitting underserved communities the hardest,” said FEMA Administrator Deanne Criswell. “That is why we must bring together and empower bright minds with bold ideas to solve one of our nation’s most dangerous and complex climate challenges.” 

“All of the DHS prize competition finalists deserve recognition for the innovative and creative solutions they brought to the table to combat climate change,” said Kathryn Coulter Mitchel, DHS Senior Official Performing the Duties of the Under Secretary for Science and Technology. “Our grand prize winner’s submission was a standout that will have a real-world impact on energy consumption and the effects of extreme heat on the public.”
Winners were selected by a judging panel of experts in climate change, resilience, and emergency management using specific selection criteria to identify solutions that will help combat extreme heat events.

Grand Prize Winner
The Grand Prize Winner is Zephyr Innovations, Inc. (Jacob Miller, CTO), of Somerville, MA. Zephyr Innovations will receive $50,000 for the Ultra-Efficient Air Conditioning via Liquid Desiccant Dehumidification and Evaporative Cooling solution. Zephyr Innovations’ solution is a cooling system that uses a compressor-free/refrigerant-free technology to significantly reduce energy consumption and the associated carbon emissions. The cooling solution scored the highest in all judging criteria.

Most Innovative
For the “Runner-up,” now renamed the Most Innovative Solution, the judges awarded $25,000 to Small World Sciences LLC (Don Chernoff), Morrisville, NC, for its Improved Cooling Textiles for Clothing, Solar Shades, and Temporary Structures. This unique concept will develop fibers with heat reflective and emissive properties based on biomimicry (mimicking the behavior) of animals that have evolved to survive in extreme desert conditions, for use in clothing and building materials to reduce heat stress and save energy. Essentially, the concept takes a page out of nature and is based on how ants cool themselves. The judges were incredibly impressed with the innovative solution and decided to change the category and add another $5,000 to the original $20,000 in this category. 

"Use Case Category Winners
Four “Use Case” Category Winners will each receive $10,000:

  • TAC Jacket Cooling Solutions (Nanohmics, Inc., Austin, TX), for first responders’ personal use or helping survivors who are at risk from heat-related stress.
  • Hybrid Cooling Wrap (Team: Young Ko, Evelyn N. Wang, and Jeffrey C. Grossman, Cambridge, MA) for personal use and helping cool individuals in indoor or outdoor environments.
  • Fuel-Flexible Ultra-Efficient Air Conditioning System for Improved Resilience (Micro Nano Technologies, Gainesville, FL) for household, group quarter or multi-person use as an alternative to conventional air conditioning or built-in cooling solutions.
  • Radiative Cooling of Structures (Hal Greenberger, Better Stuff LLC, Natick, MA) for use in indoor/outdoor venues to cool homeless or displaced populations in public settings.


Honorable Mention
The judges also designated an Honorable Mention for Creativity to CalidGear: Wearable Thermoregulatory Device (Tayyaba Ali, Wilmette, IL), which will receive $5,000.

S&T along with FEMA and its government partners plan to continue working with the providers of the most promising Challenge solutions and provide mentoring and follow-on opportunities.

DHS uses prize competitions to crowdsource innovation and harness the creativity of the American public to solve critical homeland security challenges. DHS established the first-ever Climate Change Action Group (CCAG), which is comprised of senior officials from across the Department, to focus on promoting resilience and addressing multiple risks, including flooding, extreme heat, drought, and wildfires. The CCAG oversees the implementation of the Climate Action Plan and guides the Department’s approach to managing the climate crisis.
