Wall of Wind Mitigation Challenge Overview:
The International Hurricane Research Center (IHRC), located on the campus of Florida International University (FIU), has developed the Wall of Wind Mitigation Challenge (WOW! Challenge) for South Florida high school students. This community education outreach project is graciously supported in large part through a grant from the Florida Division of Emergency Management.
The NHERI Wall of Wind (WOW) Experimental Facility (EF) located at FIU’s College of Engineering and Computing was funded by the National Science Foundation (NSF) to be a national facility that enables researchers to better understand wind effects on civil infrastructure systems and to prevent wind hazards from becoming community disasters. The WOW is the largest and most powerful university research facility of its kind and is capable of simulating a Category 5 hurricane with winds over 157 mph. Essentially, it is an array of 12 very large electric fan motors that are used to test structures, materials and products and their ability to withstand hurricane force winds.

The WOW! Challenge is a judged competition. Teams of high school students are challenged to develop an innovative mitigation concept and solution within well-defined guidelines developed by the WOW Research Team. Student teams prepare three components for the competition to address the hurricane wind mitigation challenge: a physical test, an oral presentation and a written technical paper. The mitigation concepts are tested by the WOW on the day of the live competition.
The WOW! Challenge requires problem solving, teamwork, and creativity, and the topics of science, technology, engineering, mathematics, architectural design, and business entrepreneurship. The high school students are inspired to pursue STEM education and careers in wind engineering and hurricane mitigation and be the next generation of engineers to address natural hazards and extreme weather. The competition has real world applications and benefits society as a whole by developing hurricane mitigation techniques that can lead to enhanced human safety, property loss reduction, insurance cost reduction, and a culture of hurricane preparedness.
2025 Wall of Wind Mitigation Challenge:
- The objective of the 2025 Wall of Wind Mitigation Challenge is for student teams to design a way to reduce the impact of wind scour on a building’s flat roof. Each team’s task is to develop a mitigation solution that will improve the flat roof’s aerodynamic performance to prevent pea gravel on the roof from being blown away by up-to hurricane-force winds. The mitigation solutions will be tested by the NSF-NHERI Wall of Wind in a controlled wind field to evaluate the effectiveness of the mitigation solution.
- The competition will require a written technical paper, an oral presentation and a physical wind test of a building model by the NSF-NHERI Wall of Wind. For all the details, please refer to the specific documents describing the exact instructions found in the WOW! Challenge Documents section below on this web page.
- Teachers can have as many students as they wish to participate in the Challenge. However, teams can only have up to four students be the official participants representing the team, and they would do the oral presentation. But, all other students and teachers on the team can assist with preparing all three components for the Challenge.
2025 Important Dates:
- The Wall of Wind Mitigation Challenge is Thursday, March 20th, 9am to 12:30pm.
- Written technical papers are due electronically as a PDF document by Monday, March 17th at 12:00pm.
- Pick-up or drop-off of wind mitigation barrier models will be Monday, March 17th and Tuesday, March 18th.
