LEED was created to:

• Define green building by establishing a common standard of measurement
• Promote integrated, whole-building design practices
• Recognize environmental leadership in the building industry
• Stimulate green competition
• Raise consumer awareness of green building benefits to transform the building market

The LEED Green Building Rating System™ is a consensus-based national standard for developing high-performance, sustainable buildings. The U.S. Green Building Council (USGBC) (external) offers this rating system, which certifies projects as LEED Certified, Silver, Gold, or Platinum based on the number of points achieved. LEED rating systems are available for new construction, existing buildings, homes, schools, healthcare facilities, tenant improvements, and neighborhood developments. Visit the LEED Supplement for King County to learn how LEED applies to new construction projects in King County.

Getting Certified in King County

The first step to achieving LEED Certification is to register your project with USGBC.

Registering during the early phases of project design will ensure the maximum potential for achieving certification.

Upon registration, project representatives receive an orientation letter and access to resources that explain and facilitate the formal LEED application process.
