Solatube International Receives First ICC 500 Storm Shelter Listing Report

Solatube International

What is it?
Remaining committed to delivering the most advanced, Solatube International Inc., energy-efficient daylighting technology on the market, the worldwide leading manufacturer and marketer of Tubular Daylighting Devices (TDDs), announced the achievement of another daylight industry first: The ability to daylight an ICC 500 storm shelter and FEMA P-361 safe room using the Solatube SolaMaster 750DS TDD.

Why is it needed?
An increased effort to build more tornado shelters, especially in schools and emergency response facilities, has been a priority in tornado-prone areas since the devastating tornado that hit Jarrell, Texas, in 1997. The ICC 500 ICC/NSSA Standard for the Design and Construction of Storm Shelters provides minimum design and construction requirements for storm shelters, containing basic occupant life safety and health requirements for “these shelters including means of egress, lighting, sanitation, ventilation, fire safety, and floor space”.

What are its uses?
In many cases, these storm shelters serve as dual-use facilities such as gymnasiums, cafeterias, classrooms, senior centers, or entire buildings.

Why is it important?
It is an affordable daylighting solution that delivers high protective effectiveness and pleasing design aesthetics to any facility that a community may depend on to provide safe, sheltering environments. After rigorous evaluation by the ICC Evaluation Service (ICC-ES), The Solatube SolaMaster 750DS TDD (model S750DS-O-DPI-FC CCI-EXX E-L2P) was awarded the first-ever ICC 500 Storm Shelter Listing Report, making it the only rooftop daylighting device in the world compliant for use in horizontal surfaces of tornado or hurricane storm shelters – even in EF 5 and CAT 5 territory.

What are the key aspects?
Cost-effective, energy-efficient, and eco-friendly, a Solatube TDD harvests daylight at the rooftop, transfers it down a highly reflective tube, and distributes it evenly into an interior space through a diffuser at the ceiling — on both sunny and cloudy days — with virtually no maintenance. Solatube is proud to offer the highest Light Transfer Efficiency (LTE), the most consistent Color Temperature Maintenance (CTM), and the best light-to-solar heat gain ratio of any daylighting system on the market.

The first Solatube product was sold in 1991 and today more than 2 million people have improved their homes with Solatube TDDs, and millions more have enjoyed the benefits at department stores, schools, hotels, hospitals, grocery stores, offices, and athletic facilities. Well-known Fortune 500 brands have enhanced their customers’ experiences while reducing their corporate energy costs by incorporating Solatube products into their stores, offices, and facilities. Solatube is a Safe Room Component manufacturer as well as a member of the National Storm Shelter Association (NSSA).
