Recycling & Waste Management

Our goal is to divert 50% of our landfill waste to recycling and/or compost by the end of 2023. A higher diversion rate is great for the environment and it lowers our refuse bill—a savings that’s ultimately passed back to you. Columbia Square is currently at a 43% diversion rate, so we’ll need everyone’s participation to boost that up to 50%!

BOMA 360

The BOMA 360 Performance Program sets the standard worldwide for operational best practices in the commercial real estate industry. The program evaluates buildings against industry best practices in 6 major areas of building operation, including energy efficiency and sustainability. Individual buildings that satisfy the requirements in all six performance areas are awarded the BOMA 360 designation.

LEED Certification

All Columbia Square office buildings are LEED® Gold certified under the LEED BD+C: Core and Shell rating system. This certification reinforces our longstanding commitment to developing high performance buildings. LEED is an internationally recognized green building certification system that evaluates the design, construction, and operation of green buildings. Developed by the U.S. Green Building Council (USGBC), LEED buildings provide value for tenants because they perform approximately 25% better than average in terms of energy and water consumption. This translates into cost savings on utility bills and equipment repairs, amongst other benefits.


We are excited to announce that Columbia Square Living has achieved WELL certification, administered by the International WELL Building Institute. The WELL Certification system rates the extent to which a building enhances the health and wellness and comfort of its occupants. The features that helped Columbia Square Living achieve WELL certification include: the Sun Terrace, high Walk Score™, green cleaning programs, availability of healthy food options, comprehensive emergency preparedness programs and access to water.

Sustainable Purchasing

Kilroy Realty understands the significant role material selection plays in the operation of a sustainable building. Throughout a material’s lifecycle, extraction, processing, transportation, use & disposal, there are many negative health & environmental consequences. Environmentally responsible purchasing can significantly reduce that impact.

For more information, please visit our Environmental Management System (page 58-61).

Green Cleaning

Kilroy Realty has always used the most advanced green cleaning products and practices in all of our buildings. We are constantly searching for the latest information on green cleaning and update our cleaning services whenever we see an opportunity to further minimize the environmental impact of our custodial practices. Columbia Square has an excellent Green Cleaning program which can be reviewed in our Energy Management System.

Integrated Pest Management

Pest control is an important strategy for maintaining IAQ because both pests (for example, mice) and pesticides can cause health problems. The building strives to minimize pesticide use and utilize non-chemical options where feasible. To learn more about out Integrated Pest Management Police please visit our Environmental Management System (page 46-47).

Indoor Air Quality

Optimal Indoor Air Quality is vital to good health and cognitive function. We at Kilroy Realty recognize this and as such, have a robust building health program that promotes and verifies great indoor air quality (AIQ). You can find out full AIQ policy here. You can also visit the EPA’s website to learn what you can do to improve the indoor air quality in your workspace or home.
