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

Millrock Park is located in a section of Holladay, Utah that is known as Old Mill, one of the most desirable locations in the Salt Lake valley.  Millrock consists of 4 buildings containing 494,289 square feet of Class A office space occupying different elevations within the Park allowing for unobstructed 360 degree views from every building. The timeless design and traditional architecture of the Millrock Buildings provide the highest efficiency floor plates of any buildings in the Old Mill corridor.  The parking structures are largely underground, and 75% of the parking stalls are covered keeping cars out of snow, rain and sun light. This design hides unsightly concrete structures below ground leaving 37% of the entire campus as GREEN SPACE, Truly a “Park.” Millrock Park is the only Class A office project within the Old Mill Office sub-market that provides superior access from the property onto high capacity traffic arteries that connect the corridor with the high volume Freeway interchange off of Interstate 1-215.  

Millrock has 3 entrances and exits, while the competitors only have one each.  Not only does Millrock have great accessibility it is surrounded by amenities including a variety of restaurants, hotels, health clubs, day spas, and is across the street from Old Mill Golf Course.   Sitting just outside Big Cottonwood Canyon, Millrock Park is just minutes from the mountains which offer outdoor adventures all year round from hiking and biking to skiing and snowboarding.  This is a unique location and the perfect place for our tenants that seek beauty, efficiency, accessibility and more.
