The CIR appears to be written for new construction and for sale unit properties (such as condos).\nThe 2004 LEED NC CIR states that multi-unit residential buildings must meet the requirements for commercial buildings (covering common area, owner controlled areas of the building), and the following for the residential, tenant controlled areas:\nItem #1: Educate the residents on the green cleaning concepts and products via discussion and written materials upon move-in and periodically thereafter.\nItem #2: Provide an estimated six-month supply of green cleaning products to residents, as well\nas information on how to easily purchase refills and/or replacements.\nAssume that a Multi-Family Residential Apartment (Rental) Property complies with the following:\n1.\nThe property that is applying for LEED EB certification meets all the requirements for LEED EB Green Cleaning credits for common spaces/owner controlled spaces including the cleaning policy and plan, products purchased and used, equipment purchased and used, and also follows the same green cleaning procedures whenever they have access to residential apartment units (including during all " "The project has proposed an alternative compliance path for 2009 Existing Buildings: Operations & Maintenance projects that include multi-family residential units for IEQ Prerequisite 3: Green Cleaning Policy, IEQ Credit 3.1: Green Cleaning High Performance Cleaning program, and IEQ Credit 3.3: Green Cleaning- Purchase of Sustainable Cleaning Products and Materials using Innovation in Design credit requirements outlined in Formal Inquiry dated 04/08/2004 ID #766 for multi-family New Construction projects. The proposed approach is not acceptable. \n\nFor IEQ Prerequisite 3: Green Cleaning Policy and IEQc3.1: Green Cleaning-High-Performance Cleaning Program, the green cleaning policy and program includes resident areas. Additional steps should be taken to educate the residents on the green cleaning concepts and recommended products via discussion and written materials upon move-in and periodically thereafter. Examples of acceptable steps could include a written program, a brochure, a coupon for discounted purchase, or a bulk supply of cleaning supplies available at maintenance office. \n \nFor existing building projects with multi-family spaces attempting IEQ Credit 3.3: Green Cleaning- Purchase of Sustainable Cleaning Products and Materials the percent of total annual purchases must include all cleaning purchases made for the building, regardless of who purchased the products (residents or building staff).\nApplicable internationally."

When used as directed with tap water in the majority of municipalities, this low-level electric field can kill more than 99.9 percent of harmful germs.\n\n Using an ionized water cleaning system would no longer require purchase of many green cleaning chemicals; therefore, the project team has developed a new approach to documenting IEQc3.3. Rather than documenting that 30 percent of the products purchased meet the LEED sustainable cleaning criteria (by cost), the project team proposes to document the cleaning methods used during each cleaning shift. After each shift, the housekeeping personnel will document the cleaning methods and chemicals (or tap water if using the electrolyzed water system) used. Sustainable methods and chemicals that meet the LEED requirements for this alternative compliance approach will include either the use of chemicals that meet existing IEQc3.3 requirements or the use of ionized tap water.\n\n An alternative compliance table will be created by the project team to account for criteria (with regard to performance vs. purchases) in order to demonstrate compliance with the SSc3.3 requirements. " """The project team seeks allowance to satisfy the credit requirements through the use of ionized tap water in lieu of chemical cleaning solutions. This is an acceptable approach if the following criteria are met:\n •Manufacturer’s documentation of third-party performance testing is included with the credit submittal documentation. The testing should demonstrate performance comparable to Green Seal, Environmental Choice, or another standard equivalent to or more stringent than those required in IEQc3.3: Green Cleaning—Purchase of Sustainable Cleaning Products and Materials. \n •If the device is marketed and used for antimicrobial cleaning, manufacturer’s testing must demonstrate antimicrobial performance comparable to EPA’s Office of Pollution Prevention and Toxics (OPPT) and Design for the Environment (DfE) requirements as appropriate for use patterns and marketing claims.\n •A custodial effectiveness assessment is performed as outlined in IEQc3.2: Green Cleaning—Custodial Effectiveness Assessment. \n •The typical performance metric (percentage of purchases based on cost) for evaluating compliance with this credit will not apply. The project team may show compliance with one of the following:\n a) Showing, based on one year of historic cleaning chemical costs, that use of ionized tap water during the performance period has reduced the purchase of chemical cleaning and material products by at least 30%. Any changes in occupancy or other factors that vary between the baseline year and the performance period that affect the need for cleaning products must be accounted for in the analysis.\n b. Tracking the total cost of all cleaning and material products purchased during the performance period, plus the amortized cost for the ionized water cleaning system (amortized over 12 months). \n c) Tracking the total volume of cleaning and material products and ionized water used during the performance period and showing that 30% meets the existing IEQc3.3 criteria or is ionized tap water.

In order to fulfill the intent of this credit, all copy and maintenance rooms have hard ceilings and self-closing doors, and will be exhausted sufficiently to create negative pressure. Air filtration media will provide a MERV rating of 13. Walk-off mats will be installed at all regular entry points into the building, and a cleaning service will be contracted to replace the dirty mats and clean them off-site. We are asking whether the design and cleaning program of our 16 loading bays will comply with the requirements of this credit. To prevent contaminants from entering the building, our loading bay area has been designed with a continuous pit and vertical storing system for the loading docks. We use this design because it far exceeds traditional pit set-up both for cleanliness and thermal efficiency. Such a system differs from the norm for three reasons relevant to this credit: 1) The dock doors close all the way to the dock floor when not in use, preventing dirt and debris from entering. A tight seal is made between floor and door, further hindering pollutant entry. 2) The continuous pit - a space approximately 4ft deep between warehouse floor and bay door which runs the length of the dock bay area and is 18 inches lower than the warehouse floor - serves as a catch basin for dust or particulates coming into the building and allows for easy routine cleaning. 3) Vertical storing dock leveler design further supports easy routine pit cleaning and wash downs by remaining out of the way when not in use. We believe that the innovative design of our loading bays - coupled with the planned stringent cleaning program of this food-grade manufacturing plant - meets the intent of credit EQ 5. Please advise." "The project team is asking whether providing a continuous pit in the loading dock would meet the entryway system requirements of the credit. As described in this CIR, the loading dock entryways into the warehouse do not qualify as regular entry points for building users and thus do not need to be provided with entryway systems. The strategies employed by the project team to reduce indoor chemical and pollutant sources are commendable and encouraged but they are not required by this credit.\n\n **Update October 1, 2013: Applicable credits have been updated."
