National Wind Institute

The National Wind Institute (NWI) is a research center focused on wind engineering, severe weather, and wind energy solutions to improve safety and resilience.

What is the National Wind Institute?

The National Wind Institute (NWI) is a leading research center at Texas Tech University, dedicated to the study of wind science, severe weather, and wind-resistant infrastructure. NWI conducts extensive research on tornadoes, hurricanes, and extreme wind events to enhance building safety and storm preparedness.

NWI is recognized for its pioneering work in wind engineering, including the development of the Enhanced Fujita (EF) Scale, which improves the classification of tornadoes based on damage assessments. Researchers at NWI also design storm shelters and safe rooms to withstand extreme winds, helping communities prepare for severe weather.

The institute collaborates with government agencies, meteorologists, and industry professionals to advance wind energy technologies and improve building codes. Their studies contribute to the development of safer structures, such as above-ground and underground tornado shelters, ensuring better protection for homes and businesses.

By leveraging cutting-edge research, NWI plays a crucial role in mitigating storm damage and enhancing public safety, making it an essential resource for those in tornado-prone regions.

Installation & Service Area Info

We proudly install storm shelters across Oklahoma only — we do not travel to other states, and we’re unable to make exceptions — but there are a few things to know:

  • Above ground shelter installations over 60 miles from our office in Bridge Creek may include a delivery charge.

  • Below ground shelter installations are typically limited to a 60-mile radius, though we occasionally go a bit farther with an additional fee.

  • We do not install or remove storm shelters inside garages.

➡️ Please check our Service Area page for more details about where we travel.
