Kilroy Realty’s 350 Mission Street Building Earns LEED Platinum Certification

Kilroy Realty Corporation today announced that its 350 Mission Street building located in San Francisco, California has achieved LEED Platinum certification under the Core & Shell rating system created by the US Green Building Council. The office component of the 30-story, 450,000 square foot project is 100% leased to Salesforce and represents KRC’s first ground-up development project in San Francisco. Sustainable elements were incorporated into many aspects of the building design.

KRC has a successful track record of sustainability achievements. GRESB, widely recognized as the most rigorous standard for measuring the sustainability performance of real estate companies and funds, named KRC the North American leader in sustainability for the past two consecutive years.

“We are thrilled to achieve yet another milestone in pursuit of KRC's commitment to high-performance work environments that minimize environmental impact,” says Chris Heimburger, Senior Vice President of Development at KRC.

The 450,000 square foot building is an environmentally-focused design that includes the following features:

  • 33% energy savings over LEED baseline
  • Reuse of stormwater in irrigation and domestic restrooms
  • Underfloor HVAC
  • Abundant daylighting
  • Capability of using 100% outside air for cooling
  • Destination-controlled elevator system
  • Innovative structural system that reduced steel requirements by 1.2 million pounds and concrete by 600 truckloads
  • Materials purchasing focused on recycled content, regional sourcing and FSC wood
  • Efficient lighting and mechanical systems
  • Enhanced commissioning
  • Low-emitting materials and rigorous construction air quality management
  • Electric car charging stations and Zipcar parking spaces

The project was designed by Skidmore, Owings & Merrill, LLP and WSP Flack & Kurtz created the mechanical, electrical and plumbing design. Webcor Builders oversaw the construction of the project, and Environmental Building Services executed the commissioning work.

350 Mission is located in the vibrant South of Market (SoMa) District and adjacent to the future Transbay Transit Center and Caltrans rail. With the completion of 350 Mission and 333 Brannan, KRC’s San Francisco commercial real estate portfolio, primarily centered in SoMa, totals approximately 2.8 million square feet.
