What is LEED NC v2.2?

Thu, 2009-09-24 00:32

LEED for New Construction and Major Renovations (LEED NC v2.2) is a rating system for buildings that was designed to guide and distinguish high-performance buildings that have less of an impact on the environment, are healthier for those who work and/or live in the building, and are more profitable than their conventional counterparts.

Just when many of you are becoming familiar with LEED NC v2.2, it’s time to get ready for the launch of LEED 2009, scheduled for April 27.

What’s Changing with LEED New Construction? 

The rating system will now start to be revised on a periodic basis, incorporating a “transparent environmental/human impact credit weighting” scheme, and adding some form of regionalism into the point system. LEED-NC, LEED-CS, LEED-CI, LEED-EB, and LEED for Schools are all being edited under the new system. 

The credits themselves will barely change. Some of these include a Water Efficiency prerequisite (the 20% threshold is now a prerequisite). The EAc1 points are now based on ASHRAE 90.1-2007. The credit for CRI Green Label carpets (EQc4.3) expands to include other flooring options. Bonus points can also be earned based on the building’s regional location.
