Latest Concepts in LEED v4

New Concepts for LEED v4

Where is LEED v4 taking the green building industry next? After a mostly restructuring upgrade to LEED 2009, the US Green Building Council (USGBC) is pushing ahead with more innovative concepts in LEED v4 for making our built environment more sustainable; while continuing to fine-tune the more familiar LEED certification requirements.

The next evolution and transition to LEED v4 hasn’t been easy. After four public comment drafts, the USGBC elected to not launch the changes originally intended under LEED 2012. Instead they pushed for a planned member ballot in 2013 and renamed it to LEED v4. The USGBC is optimistic that the fifth comment period will be the last and the member ballot is scheduled for June 2013. If the ballot is approved, LEED v4 will become available sometime later in the summer or fall of 2013. LEED 2009 will remain available until June 2015.

LEED v4 is introducing a number of programs, terms, and concepts that are likely to be unfamiliar even to the most experienced LEED consultants and building industry professionals. For example, BUG ratings, LID infrastructure, Building Envelope Commissioning (BECx), and spatial daylight autonomy are a few of the new concepts in the LEED v4 certification system.

Check back often as we will summarize some of the new concepts in LEED v4 that will likely shape the green building industry for years to come.
