Green Features


Block 300 is Energy Star certified, and was awarded by BOMA as being the second most energy efficient building in Portland in 2008. The property was also recognized as being the first entire private office building in the city to become certified under the BlueWorks recycling program, which involves extensive building-wide recycling, food composting, and donating reusable items to local schools.

In keeping with ownership’s commitment to the health of the building’s occupants and the environment as a whole, Block 300 is pursuing LEED certification from the U.S. Green Building Council. These additional green enhancements will reduce tenants’ energy costs and further increase occupant comfort.
