The manufacturers of the household cleaners (non-concentrates) currently in use at the residence have provided MSD sheets and letters confirming that they meet and/or exceed GS-37 requirements. In other words, they are all green, environmentally friendly cleaning products that meet the intent of the credit, in our opinion. We hope that USGBC accepts these products for the corresponding point(s)." "To meet MRc4\'s Sustainability Criteria A, cleaning products must be Green Seal GS-37 certified or establish equivalency via third-party verification. It is not enough for the Building Applicant to just submit a MSDS and a letter from the manufacturer that the cleaning products meet or exceed Green Seal GS-37 requirements. The Building Applicant must also provide documentation that summarizes and verifies on a point by point basis how the cleaning products meet or exceed the Green Seal GS-37 requirements. Building Applicants may only default to Sustainability Criteria B California Code of Regulations maximum allowable VOC level requirements for cleaning products not covered by GS-37 categories.

For MRc4 we would like to use a cleaning product line that has Environmental Choice certification (CCD-110,146 and 148) but not GS-37 certification. Since the new version of LEED-EB accepts Environmental Choice as a qualifying third-party verification standard, will you approve the substitution for our building certification?" "The following sustainable purchasing standards or criteria for cleaning materials and products, disposable janitorial paper products and trash bags are acceptable for documenting qualifying purchases on a cost basis to meet the LEED-EB v2.0 MRc4 sustainability criteria. Cleaning products: o Green Seal GS-37 for General-Purpose, Bathroom, Glass, and Carpet Cleaners Used for Industrial and Institutional Purposes. o Environmental Choice CCD-110 for Cleaning and Degreasing Compounds. o Environmental Choice CCD-146 for Hard surface Cleaners. o Environmental Choice CCD-148 for Carpet and Upholstery Care. If the above standards are not applicable for a specific product category (e.g., for products such as disinfectants, metal polish, floor finishes or strippers), products shall meet one or more of the following programs for the appropriate product category: o Green Seal GS-40 for Industrial and Institutional Floor-Care Products. o Environmental Choice CCD-112 for Digestion Additives for Cleaning and Odor Control. o Environmental Choice CCD-113 for Drain or Grease Traps Additives. o Environmental Choice CCD-115 for Odor Control Additives. o Environmental Choice CCD-147 for Hard Floor Care. o California Code of Regulations maximum allowable VOC levels for the specific product category. Disposable janitorial paper products and trash bags: o U.S. EPA Comprehensive Procurement Guidelines for Janitorial Paper and Plastic Trash Can Liners. o Green Seal GS-09 for Paper Towels and Napkins. o Green Seal GS-01 for Tissue Paper. o Environmental Choice CCD-082 for Toilet Tissue. o Environmental Choice CCD-086 for Hand Towels.

"10301" "None" "X" "LEED Interpretation" "2460" "2009-04-06" "Existing Buildings" "The project building proposes to earn credit toward EQ 3.4-3.6 by purchasing high density plastic trash can liners that contain less than 10% recycled content but also have a thickness of no more than 0.70 mils. This proposed exclusion to the EPA\'s procurement guidelines for plastic trash can liners is based on the principal of source reduction and the desire to minimize the project building\'s purchase of virgin plastic. The proposed guideline of 0.70 mils is based on the California Recycled Content Trash Bag Program outlined in the California Code of Regulations Title 14, Chapter 4, Article 5. While the EPA\'s procurement guidelines call for plastic trash can liners that contain a minimum 10% recycled content, it is impractical for liner manufacturers to produce a functional plastic trash liner which contains at least 10% recycled content but is also 0.77 mils thick or less. Major manufacturer\'s Heritage Bag, Pitt Plastics and Berry Plastics each produce bags with 10% recycled content, but the minimum thickness of these bags is 1.0 mil. These manufacturers have informed the project team that it is impractical to manufacture a thinner bag with 10% recycled content without compromising the tensile strength of the bag and consequently requiring ""double bagging"" in the field. From a source reduction standpoint, a 0.70 mil virgin bag contains 24% less virgin plastic than a 1.0 mil bag that contains 10% recycled content. The California Recycled Content Trash Bag Program requires trash liners to contain at least 10% recycled content, but the Board also provides an exclusion for liners with a thickness of 0.70 mils or below. Please clarify whether the US Green Building Council would allow the project building to earn credit toward EQ 3.4-3.6 for the purchase of high density plastic trash can liners that contain less than 10% recycled content but also have a thickness of no more than 0.70 mils." "In order to count towards EQ Credit 3.4-3.6, disposable plastic trash liners must contain at least 10% post-consumer recycled content. However, liners less than 0.70 mil in thickness can be excluded from the calculations (not being counted as a compliant or non-compliant purchase) . To exercise this exclusion, include information about the excluded product, including manufacturer documentation demonstrating thickness. Applicable Internationally. " "None" "None" "X" "LEED Interpretation" "5404" "2009-07-29" "Existing Buildings" "The building management team is planning to implement a LEED-EB compliant green cleaning program that includes the purchase of compliant cleaning chemicals. The building management team is considering using the Procter and Gamble cleaning products listed below, and has requested from Procter and Gamble documentation from a third party testing laboratory that summarizes and verifies on a point by point basis how each of the listed Procter and Gamble cleaning products meets or exceeds the requirements of the applicable standard for each chemical (Green Seal GS-37 or CARB VOC). Once we have this documentation in hand for each of these cleaning chemicals so it is available to submit with the certification application for our building, will these be considered compliant chemicals for the LEED-EB Sustainable Cleaning Products and Materials calculations? General Purpose Cleaners Covered by GS-37: Mr. Clean Finished Floor Cleaner, Spic and Span Liquid Cleaner, PGPL Heavy Duty Spray Cleaner Disinfects Covered by CARB VOC: Spic & Span Disinfecting All-Purpose Spray & Glass Disinfectant, Comet Disinfecting Bathroom Cleaner, PGPL Daily Sanitizing Restroom Cleaner, PGPL Disinfectant Floor Cleaner, Comet Disinfecting Cleaner with Bleach, Mr. Clean Toilet Bowl Cleaner/Restroom Disinfectant, Clean Quick Broad Range Quaternary Sanitizer, PGPL Carpet Extraction Cleaner Sanitizer Floor Finishes Covered by CARB VOC: PG ProLine Super Durable Finish, PG ProLine All Around Finish, PG ProLine Spray Buff and Mop-on Maintainer Floor Strippers Covered by CARB VOC: PGPL Floor Stripper Carpet Cleaners Covered by CARB VOC: PGPL Bonnet/Traffic Lane Cleaner, PGPL General Use Carpet Spot Remover, PGPL Tannin Spot Carpet Spot Remover" "It is acceptable to provide 3rd-party assessment demonstrating compliance with the LEED green product certification criteria, providing that the testing performed assesses all aspects of the applicable standard and is performed in accordance with the testing protocols employed by the cited standard. The burden of demonstrating equivalency to the cited standards and testing protocols is the responsibility of the project team. Additionally, many of the products listed above seem to inappropriately be classified as covered by CARB VOC limits when Green Seal GS-37 criteria would apply. Most general purpose cleaners, restroom cleaners, carpet cleaners, and glass cleaners are expected to fall under the GS-37 criteria. Reverting to the less robust CCR (California Code of Regulations) classification to avoid testing against GS-37 criteria is not appropriate for any product that falls under GS-37 based on the definitions provided under Section 2 of that standard. For example, GS-37 defines glass cleaners as ""products used to clean windows, glass, dry erase boards, and mirrored surfaces."" Any product used in the project building in that capacity must be tested against the GS-37 criteria for glass cleaners. It is the responsibility of the project team to justify that GS-37 criteria do not apply for all products for which the less robust CARB VOC is used. Applicable Internationally. " "None" "None" "X"
