“The Music Center in downtown Los Angeles … is the first performing arts organization in the country to receive a UL ‘healthy building’ verification, representing high standards for air quality at four venues—Walt Disney Concert Hall, Dorothy Chandler Pavilion, Mark Taper Forum and Ahmanson Theatre,” writes Jessica Gelt in Thursday’s (3/25) Los Angeles Times. “Don’t throw away your mask just yet, though…. Sean McCrady, director of assets and sustainability, real estate and properties at UL, the safety science company that issues the Verified Healthy Buildings for Indoor Air Verification Mark … reiterated the scientific consensus that air purification and good ventilation can reduce airborne germs in indoor spaces…. The coronavirus spreads most commonly through the inhalation of droplets and tiny respiratory particles…. The UL verification program emphasizes filtration, ventilation and the overall hygiene of air systems and of buildings in general. Buildings are required to use MERV 13 air filters.… McCrady said the filter has an 85% efficacy rate and captures much of the particulate matter to which the virus hitches itself…. The Music Center hopes the UL verification will help to maintain the trust of audiences, said Chief Operating Officer Howard Sherman.”
