S.F.'s 350 Mission Becomes World's Largest Commercial Building To Receive Zero Waste Certification

Kilroy Realty's 350 Mission, also known as Salesforce East

San Francisco can now boast the world's largest commercial property to receive TRUE Zero Waste certification.

Kilroy Realty Corp.'s 350 Mission St. is the first commercial building in San Francisco to receive the certification, and at more than 455K SF, it is the world’s biggest. The U.S. Green Building Council awarded the building gold-level certification, adding to its LEED Platinum, Energy Star and Fitwel certifications.

“We wanted to take a bold and meaningful stance on waste management to reaffirm our commitment to minimize the environmental impacts of our buildings,” Kilroy Director of Sustainability Maya Henderson said. “Undergoing the rigorous TRUE certification process also had the added benefit of helping to optimize building operations and cost savings.”

The building, known as Salesforce East, is part of Salesforce's seemingly insatiable hunger for space in the city. Salesforce leased all of the office space in 350 Mission before it completed in 2016. The company now occupies more than 2M SF across 123 Mission St., Salesforce East, Salesforce West at 50 Fremont St. and the newly opened Salesforce Tower. In the fourth quarter of last year, the company signed a lease for Transbay Parcel F, which isn't even permitted yet.

The TRUE Zero Waste certification recognizes facilities that achieve at least 90% waste diversion. 350 Mission St. achieved 91.9% diversion and met other performance requirements, according to Kilroy Realty.

To reach the goal, the company invested in reusable pantry supplies and ordered in bulk, developed ongoing education and awareness programs, replaced individual desk trash cans with central waste collection and started post-sorting services.

Kilroy Realty has been recognized for its sustainability efforts across its portfolio. In 2018, GRESB recognized the company as North American leader across all asset classes and global world leader among all publicly traded real estate companies. At the end of the third quarter, the company's stabilized portfolio was 59% LEED certified and 77% of properties eligible for Energy Star held that certification.
