SITES Education

Coming soon on the ASLA Online Education and USBGC Education websites: SITES Webinar on Section 2.2 Pre-Design Assessment and Planning 

We are excited to share news regarding the next phase for SITES. ASLA and the University of Texas at Austin have transferred ownership of the SITES Rating System to Green Business Certification Inc. (GBCI), the certification body for the LEED green building program from U.S. Green Building Council (USGBC), and GBCI is now accepting applications for project certification under the SITES v2 Rating System.

We are confident that GBCI’s leadership of SITES will take the program to the next level and ensure its future growth and influence. ASLA will continue to contribute to the development of SITES as a member of the SITES advisory council and will support the Initiative through ongoing education and promotion activities. ASLA members will continue to be involved on the technical committees that support the Rating System. The role of ASLA, The Lady Bird Johnson Wildflower Center at The University of Texas at Austin, and the United States Botanic Garden in the development of SITES will be recognized in SITES materials and communications. ASLA members are entitled to discounts for all SITES materials, certification, and, when developed, credentialing.About the Rating System
