CLAYCO’S NEW ST. LOUIS OFFICE SHOWCASES A COMMITMENT TO ENVIRONMENTAL RESPONSIBILITY

BY REPURPOSING EXISTING SPACE AND INTEGRATING SUSTAINABLE MATERIALS, GREEN SPACES, AND EV CHARGING STATIONS, ALL WHILE REDUCING EMBODIED CARBON TO MINIMIZE ENVIRONMENTAL IMPACT.

DAYLIGHT ENHANCEMENT

We achieved an 11% increase in natural daylight availability.

Overall, we achieved...

10% reduction of glare from the South 30% reduction of glare from the East

12% reduction of glare from the West

ADAPTIVE REUSE CASE STUDY

Clayco’s New St. Louis Office

PLANNING FOR HEALTH & WELLNESS We used biophilic design—daylight, vegetation, and natural materials—to reduce stress by up to 30%. The smooth indoor-to-outdoor gym transition and integrated art gallery promote a healthy work-life balance for employees.

SITE IMPROVEMENT

We increased green space by 115%, reaching 162,000 sq ft for groundwater recharge, air quality, and communal areas. Landscaping uses 100% native vegetation for biodiversity and low maintenance. Carbon sequestration will reach 525 tons over 50 years, equivalent to removing 114 cars’ CO2 emissions annually.

The existing building at 8640 Evans Avenue was developed, designed, and built by Clayco in 2012 and was occupied by Express Scripts until 2022. Our team chose adaptive reuse over new construction, significantly reducing our ecological footprint.
