LEED 2009 is Coming Soon

LEED 2009 (LEED 3.0) is coming April 27.

The new version of the LEED rating system will incorporate all of the rating systems that address commercial buildings–New Construction, Commercial Interiors, Schools and Existing Buildings: Operations &
Maintenance–into three LEED 2009 systems:

* Green Building Design & Construction
* Green Interior Design & Construction
* Green Building Operations & Maintenance

Most credits will be very familiar, but LEED 2009 includes some important changes:

* All prerequisites and credits have undergone an alignment and harmonization, providing a pool of prerequisites and credits for all LEED Rating Systems
* Various credits are re-weighted based on impact on environment and health, with improving energy efficiency and reducing carbon emissions being the primary goal
* Regionalization of certain credits

There are some significant lighting changes related to the prerequisite and credits available or energy reduction compared to 90.1 (2007 now instead of 2004), light pollution reduction and daylighting and views.
