100 First St. - LEED for Existing Buildings Gold.

Key to KRC’s sustainability efforts are the programs that constitute its multi-pronged Green Building Operations initiative. The initiative has saved significant energy and water, increased landfill diversion rates and improved indoor air quality across its portfolio.

Water Efficiency and Recycled Water

KRC is committed to water-use reduction both inside and outside its buildings. In addition to using low/dual flush toilets and faucet aerators, it is one of the few companies with a standard practice of installing waterless urinals (which save an average of 40,000 gallons of water every year) throughout its portfolio and will continue to do so in all new development when possible. New development must achieve LEED-compliant irrigation efficiency, and KRC’s weather‑based irrigation systems reduce or eliminate watering cycles in the rainy season. The company is also pursuing upgrades to its cooling towers to manage process water use, and connects to municipal recycled water systems wherever available. KRC saved over 7.3 million gallons of water in 2011 through use of reclaimed water. Read more here.

Waste Reduction and Recycling

KRC is in the process of rolling out a recycling revitalization program across its portfolio. In this program, tenants throw away only recyclable materials at their desks, and take their non‑recyclable waste to common area bins. This change has resulted in a jump from an 11 percent landfill diversion rate to a 65 percent diversion rate in the new program’s pilot buildings, and KRC is extending this program to its Calabasas properties in 2012.

In 2011 the company launched a composting program in one million square feet of office property in its El Segundo buildings. The program has been very successful, which is why it was rolled out to additional buildings in 2012; further deployments are being considered for 2013.

The company also implemented paperless invoicing and a robust e‑waste program in all of its office buildings. KRC ensures that e‑waste providers process its electronic waste domestically and according to U.S. regulations.

The first three months of the revitalized waste reduction and recycling program saw savings of 141 cubic yards of landfill space, 252,000 gallons of water, 85 barrels of oil, 696 mature trees, and enough electricity to power 13 homes. Additionally, the implementation of paperless invoicing led to increased accounting efficiency for KRC employees.

Green Cleaning Program

KRC launched its Green Cleaning Program in 2010 by extending the highly effective green cleaning programs from two of the company’s LEED for Existing Buildings Gold properties to the rest of its office portfolio. In the program, all cleaning products must meet the relevant LEED environmental standard, either Green Seal or the California VOC limit. Vacuums must achieve the Carpet and Rug Institute Seal of Approval, and janitorial staff use microfiber cloths and rags to capture additional dirt to improve air quality. The company replaced many of its traditional plastic trash bags with a biodegradable product, others with a compostable product, and has begun reducing virgin tree fiber in restroom paper products. These efforts have led to improved air quality for janitorial staff and tenants, as well as environmental benefits.

Tenant Engagement

Tenants control a wide portion of a building’s resource consumption, and engaging them directly is an important component of Kilroy’s sustainability policy. Quarterly tenant sustainability communications address recycling, green cleaning, and energy efficiency, and periodic in-person meetings with tenants serve to revitalize participation in sustainability programs.
