The UL Verified Healthy Building Program by Underwriters Laboratories (UL) aids building owners in fostering spaces that prioritize both occupant health and environmental sustainability. Through rigorous evaluations of factors like indoor air and water quality, the program aligns with standards from renowned bodies like ASHRAE and WHO. The verification process involves an in-depth assessment by UL experts, followed by actionable recommendations. Post-implementation, a second review ensures enhanced indoor quality. This program's significance lies in its focus on indoor health, given our extensive time spent indoors, and its contribution to broader sustainability goals, offering a competitive edge in real estate.
