Energy Standards for Public Buildings
Seattle’s Sustainable Building Policy was originally adopted in 2000 and significantly expanded in scope in October 2011. This policy calls for new City-funded projects and major renovations with over 5,000 square feet of occupied space to achieve a Gold Rating using the US Green Building Council’s (USGBC) LEED Rating System. In addition, these projects must meet additional energy efficiency, water, waste, and bicycle parking requirements.
Minor renovation and tenant improvement projects that impact 5,000 square feet or more and involve changes to mechanical, electrical, and plumbing systems must also meet LEED Gold standards, as well as additional requirements for water and waste. Projects that are under 5,000 square feet or not eligible for LEED must complete the Capital Green checklist. As of December 2013, 34 LEED certified City buildings have been completed under the Sustainable Building Policy, 32 of those buildings receiving LEED certification.
