Verified Healthy Building for Indoor Air and Water

Verification Method

UL’s Healthy Buildings Verification Mark for Indoor Air and Water 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 and water 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

535 Mission Street was developed in 2013 from the ground up as a new 28 story, 330,000 square foot office building.  The all-steel construction rocketed out of the ground sandwiched between other developments.  The modern building architecture is impressive and the building operating systems amazing.  With fan wall air systems, the building has great performance and still delivers 100% outside air most of the year.  Built with DDC systems from the ground up, made energy efficiency easy to achieve and maintain.  Destination based elevators are very versatile transportation platforms and adjust easily to tenants needs. Being immediately adjacent the Transit center, Muni at the front door and a block from BART, makes commuting a breeze.
