Verified Healthy Building for Indoor Air
UL’s Healthy Buildings Verification Mark for Indoor Air demonstrates that indoor spaces provide healthy indoor air quality (IAQ). It shows a commitment by building owners and managers to create and maintain indoor environments that support tenant health, well-being and comfort, backed by UL’s globally recognized expertise in IAQ and building health. These buildings meet rigorous performance criteria and have policies and plans in place for continual advancement of IAQ. To achieve the UL Healthy Buildings Verification Mark, spaces underwent a desktop audit and on-site visits that include visual inspections and performance testing to evaluate a range of building conditions. The program includes an annual comprehensive assessment coupled with surveillance at the mid-year point. The IAQ testing requirements verify that the building air meets rigorous standards. These standards are aligned with industry-recognized, third-party organizations such as the Environmental Protection Agency (EPA), the National Institute for Occupational Safety and Health (NIOSH), the World Health Organization (WHO) and the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), among others. All laboratory testing and analysis methodologies are informed by the EPA Compendium of Methods, ASTM D5197 and TO-17 for air sampling, and EPA methods.
The Cary Fire Department provides fire, rescue and EMS services to a population of approximately 179,000 in a jurisdiction covering about 60 square miles. It operates out of nine fire stations and an administrative office building and employs about 240 personnel. Fire suppression crews, all of whom are full-time career employees, respond to more than 10,000 emergencies per year. Cary’s Fire Station 4 is the first fire station in the world to earn the Verified Healthy Building distinction. The single-story, 9,000 square foot building opened in 1988 and crews provide 24-hour coverage protecting the citizens of Cary. Fire stations serve as work and home to their crews during their 24-hour shifts, with a “day side” providing office space, a kitchen, and living room area; the “apparatus bay” housing the station’s fire trucks; and the “night side” accommodating a common dormitory with beds for each firefighter, bathrooms, locker rooms, and laundry facilities.
