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.

SS Prerequisite 1: Erosion & Sedimentation Control
Required

Intent
Control erosion to reduce negative impacts on water and air quality.
Requirements
Design a sediment and erosion control plan, specific to the site that conforms to United States
Environmental Protection Agency (EPA) Document No. EPA 832/R-92-005 (September 1992),
Storm Water Management for Construction Activities, Chapter 3, OR local erosion and
sedimentation control standards and codes, whichever is more stringent. The plan shall meet the
following objectives:
• Prevent loss of soil during construction by stormwater runoff and/or wind erosion, including
protecting topsoil by stockpiling for reuse.
• Prevent sedimentation of storm sewer or receiving streams.
• Prevent polluting the air with dust and particulate matter.
Submittals
Provide the LEED-NC Letter Template, signed by the civil engineer or responsible party,
declaring whether the project follows local erosion and sedimentation control standards or the
referenced EPA standard. Provide a brief list of the measures implemented. If local standards
and codes are followed, describe how they meet or exceed the referenced EPA standard.
Potential Technologies & Strategies
Adopt an erosion and sediment control plan for the project site during construction. Consider
employing strategies such as temporary and permanent seeding, mulching, earth dikes, silt
fencing, sediment traps and sediment basins.

?SS Credit 1: Site Selection
1 Point

Intent
Avoid development of inappropriate sites and reduce the environmental impact from the location
of a building on a site.
Requirements
Do not develop buildings, roads or parking areas on portions of sites that meet any one of the
following criteria:
• Prime farmland as defined by the United States Department of Agriculture in the United
States Code of Federal Regulations, Title 7, Volume 6, Parts 400 to 699, Section 657.5
(citation 7CFR657.5)

• Land whose elevation is lower than 5 feet above the elevation of the 100-year flood as
defined by FEMA.
• Land which is specifically identified as habitat for any species on Federal or State threatened
or endangered lists.
• Within 100 feet of any water including wetlands as defined by United States Code of Federal
Regulations 40 CFR, Parts 230-233 and Part 22, and isolated wetlands or areas of special
concern identified by state or local rule, OR greater than distances given in state or local
regulations as defined by local or state rule or law, whichever is more stringent.
• Land which prior to acquisition for the project was public parkland, unless land of equal or
greater value as parkland is accepted in trade by the public landowner (Park Authority
projects are exempt).
Submittals
Provide the LEED-NC Letter Template, signed by the civil engineer or responsible party,
declaring that the project site meets the credit requirements
Potential Technologies & Strategies
During the site selection process, give preference to those sites that do not include sensitive site
elements and restrictive land types. Select a suitable building location and design the building
with the minimal footprint to minimize site disruption. Strategies include stacking the building
program, tuck-under parking, and sharing facilities with neighbors.
