Green Building Rating System
For New Construction &
Major Renovations
®(LEED -NC)

Version 2.2


First Public Comment Draft




December 2004


NOTE TO REVIEWERS

Thank you for participating in the first public comment period for the LEED Green Building Rating
System for New Construction, Version 2.2. Any member of the public may comment on this rating
system, provided that the individual has registered a user profile on our website. The previous revision,
Version 2.1, addressed only process and documentation issues and was not required by the bylaws and
Foundations Document to be balloted. Version 2.2 contains substantive changes to credits and does
require balloting. The process of developing Version 2.2 was started over a year ago. The direction and
charge that the LEED-NC Committee was given for this version is as follows:

1. To fix known problems with selected LEED-NC v.2.1 credits
2. To clarify the intent of selected credits
3. To clarify the performance standards for selected credits
4. To expedite these edits
5. To put the recommended changes to membership vote in 2004


Additional guidelines included staying within the present credit structure of 69 points; no points can be
added or removed until NC version 3. The main sources of information for the version 2.2 revisions were
drawn from market and stakeholder reaction to LEED-NC version 2.1 and the Credit Interpretation
Request process. The changes that are proposed attempt to better define the criteria for satisfying a
credit and in some cases elevate these requirements. Your input, along with other stakeholders, will help
determine if there is consensus for these proposed changes as LEED seeks to further drive market
transformation and increase its penetration in various sectors.

In addition to commenting on the specific language proposed, feedback would be appreciated on the
potential cost impact, impact on the market, and impact to the certification process of the revision and the
methods in place to validate the credit as well as on the overall acceptance of Version 2.2. All responses
should be kept brief. Please note that there is a section in the comment form for general comments, as
well as sections for all credits.

After receipt of all comments, a revised Version 2.2 second draft will be issued, along with responses to all
comments received. The public will be welcomed to comment only on changes made since the previous draft,
and all comments made in that second review period will be responded to by the NC committee and
posted. After that secondary review, a final Version 2.2 will be put out for balloting. This is presently
anticipated for the fall of 2005.

stPlease note that this comment period will end at 5pm Pacific on February 1 2005. No comments
received after that time will be considered or responded to by the committee.

Also please note that the different colors of highlighted text do not differ in any substantive way. All
marked changes are suggested changes, regardless of color.

Thank you for your cooperation and dedication. We look forward to working with you.
