Our goal is to divert 95% of our landfill waste to recycling and/or compost by the end of 2018. A higher diversion rate is great for the environment and it lowers our refuse bill – a savings that’s ultimately passed back to you. 100 First Street is currently at an 80% diversion rate, so we’ll need everyone’s participation to boost that up to 95%!

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. 100 First Street has an excellent Green Cleaning program.

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.

Fitwel Certification

We are excited to announce that 100 First Street has achieved Fitwel certification, administered by the Center for Active Design. The Fitwel certification system, which rates the extent to which an existing building promotes positive health outcomes for occupants, was created as a joint initiative led by the US Centers for Disease Control and Prevention (CDC) and the General Services Administration (GSA) in addition to experts in public health and design over a five-year process completed in 2015. The features that helped 100 First achieve Fitwel certification at the 2 star level include: the Sun Terrace, high Walk Score™, green cleaning programs, availability of healthy food options, comprehensive emergency preparedness programs and access to water.
