Verified Healthy Building for Indoor Air

Verification Method

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.

About the Company

Nestled just one block from the center of Uptown Charlotte is Carillon, a 24-story office tower. Featuring dramatic, neo-Gothic architecture—including a 300-foot central spire shaped like a bell tower—and museum-quality interiors and artwork, Carillon is nothing short of striking. Designed by Thompson, Ventulett, Stainback & Associates, the spire resembles the architecture of the adjacent historic First Presbyterian Church, originally built in 1857. Carillon was completed in 1991 spanning 486,994 square feet with 9-foot floor-to-ceiling windows providing maximum natural light and a stunning copper roof. What makes Carillon unique is its artistic allure. It is home to several masterpieces listed on Charlotte’s Public Art Walking Tour that attracts hundreds of visitors each year. Most notably is Jean Tinguely’s “Cascade”, a celebrated 40-foot kinetic sculpture that is suspended above an indoor fountain in the lobby of the Carillon building. It is the last kinetic sculpture ever made before Tinguely’s death in 1991. The property is LEED Silver-certified and Energy Star-rated, providing an eco-friendly and productive work environment that is 39% more energy efficient than the average U.S. office building.
