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 commenton changes made since the previous draftonly , 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. Please note that this comment period will end at 5pm Pacific on February 1st comments2005. No 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. The LEED NC Committee Jim Goldman, chair Tom Scarola, vice-chair Lee Burgett Craig Kneeland Joe Higgins Harry Gordon Muscoe Martin Chris Dixon William O'Dell Chris Schaffner Wayne Trusty

Sustainable Sites
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 Letter Template, signed by the civil engineer or responsible party,Provide the LEED-NC 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.

9
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
Letter Template, signed by the civil engineer or responsible party,Provide the LEED-NC 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.

SS Credit 2: 1 Point
Intent
Development Density & Community Connectivity
Channel development to urban areas with existing infrastructure, protect greenfields and preserve habitat and natural resources.
Requirements
Construct or renovate building in an established, walkable community with a minimum density of 60,000 square feet per acre net (two-story downtown development),
OR
Construct or renovate building within ½ mile of a residential zone or neighborhood with an average density of 10 units per acre net AND has pedestrian access to, and is located within at least ½ mile of, at least 10 of the basic services listed:
1) Bank; 2) Place of Worship; 3) Convenience Grocery; 4) Day Care; 5) Cleaners; 6) Fire Station; 7) Hair Care; 8) Hardware; 9) Laundry; 10) Library; 11) Medical/Dental; 12) Senior Care Facility; 13) Park; 14) Pharmacy; 15) Post Office; 16) Restaurant; 17) School; 18) Supermarket; 19) Commercial Office; 20) Community Center. This credit is not available for projects locating in a greenfield development.
Submittals
architectProvide the LEED-NC Letter Template, signed by the civil engineer, other responsible party, declaring that the project has met the credit requirement
or
Provide density for the building and for the surrounding area with an area plan, highlighting the building location
OR
Provide an area plan highlighting the building location, the residential zone or neighborhood, and 10 or more of the basic services located within ½ mile of the project space (inclusive of the applicant building).
Potential Technologies & Strategies
During the site selection process, give preference to urban sites with pedestrian access to a variety of services.
