Nevada K–12 District Becomes First in U.S. to Achieve UL Verified Ventilation, Filtration Mark

HVAC and air-cleaning systems performance testing solutions provider SafeTraces recently announced that the Clark County School District (CCSD) in Nevada has become the first public school district in the U.S. to achieve the UL Verified Ventilation & Filtration (VVF) annual verification mark in its portfolio of facilities, according to a news release.

UL Verified Ventilation & Filtration launched in March 2022 and is the only performance-based rating and assessment for pathogen protection provided by public HVAC and air-cleaning systems. The verification mark is given to buildings that meet performance requirements linked to CDC ventilation targets and ASHRAE building standards, the news release reports. CCSD is the fifth-largest public school district in the country, with 374 schools and more than 315,000 students.

“We are extremely proud to become the first public school district in the nation to earn the UL-SafeTraces Verified Ventilation & Filtration mark,” said Lori Olson, Director of Environmental Services at CCSD. “This achievement demonstrates Clark County School District's leadership and commitment to ensuring a healthy learning environment for all of our students, teachers, and staff. Moreover, it is one of the best and smartest investments that we can possibly make to improve student attendance, enrollment, and performance in order to ultimately deliver on CCSD's mission and strengthen our foundation for the future.”

The verification process involves a building-level desktop audit, as well as measurement and verification of air-cleaning system and HVAC performance in high-occupancy buildings. The process uses SafeTraces’ veriDART biotechnology-enabled performance testing and analytics platform.

“Led by Lori Olson and her team, CCSD's achievement of the UL VVF mark sends a powerful message to public school districts across the country about the fundamental importance of indoor air quality and pathogen protection to a healthy learning environment,” said SafeTraces CEO Erik Malmstrom. “Public school facilities are fully capable of meeting health-based ventilation standards with strong leadership and will, and without necessarily entailing significant cost and disruption. Other public school districts should follow CCSD's inspiring example. And our society should hold our school facilities to a higher standard and support them to do achieve this standard.”
