"1. Mechanical and Electrical -- CSI MasterFormat 1995 Divisions 15 & 16 -- are to be excluded from the calculations (numerator and denominator) for MR Credit 3, Resource Reuse; MR Credit 4, Recycled Content; MR Credit 5, Regional Materials; and MR Credit 6 Rapidly Renewable. Note that this is already stated in LEED-CI v2.0 Reference Guide for MRc3 (pages 222 & 224) and MRc4 (page 229 per balloted Rating System and page 234). \n2. Plumbing products shall not be permitted to contribute to the numerator of MR Credit 3.1/3.2, Resource Reuse. Plumbing products, as well as Division 12 items (furniture and furnishings), shall be excluded from the denominator of the calculation. Note that this is already stated in LEED-CI v2.0 Reference Guide on page 223. \n3. Plumbing products are left to the discretion of the project team for MR Credit 4, Recycled Content, and MR Credit 5, Regional Materials. If plumbing products are used for one of these credits, for the sake of consistency, they must be part of the calculations for both credits (numerator and denominator). Note that this will be a Reference Guide errata item. \n4. Plumbing products are not applicable to MR Credit 6, Rapidly Renewable. Thus, the denominator of the calculation will be different than MR Credits 4 and 5 if plumbing contributes to those two credits. Note that this will be a Reference Guide errata item. \n5. Divisions 11, 13, and 14 are left to the discretion of the project team; item by item may be added to both the numerator and denominator, as long as there is consistency between MR Credits 3 - 6. 6. Note that MR Credits 1.2/1.3 (Building Reuse), 2 (Construction Waste Management), 3.3 (Furniture Reuse), and 7 (Certified Wood) use different calculations such that the ""materials cost"" (denominator) and thus this issue are not applicable. These conclusions will result in the following necessary edits to the LEED-CI v2.0 First Edition Reference Guide: A. Amend Table 2 on page 193 as follows: add an ""X2"" to the ""Mechanical"" row for MRc5.1 and 5.2; add an ""X"" to the ""Mechanical"" row for MRc6; and add an ""X"" to the ""Electrical"" row for MRc5.1, 5.2, and 6. Also, the footnote for ""X2"" should simply state ""Plumbing products may be included in calculations; if included for one credit, items must be in all applicable credits."" B. Clarify Table 2 on page 222 so that Division 12 is not part of the numerator or denominator as explained correctly on page 221. C. Add clarifications noted in #1 above for MR Credits 5 and 6. D. Add clarifications noted in #3 and #4 above." "None" "None" "LEED Interpretation" "1859" "2007-08-27" "Commercial Interiors" "MRc3.2 - Materials reuse - furniture and furnishings" "Our client has created a master plan on the relocation of their existing furniture and furnishings, which accounts for over 30% of their total new furniture and furnishings budget. Their plan is to divert approximately 15% of existing furniture and furnishings to their new facility, 30% to another office of theirs in a nearby city, less than 15 miles away. In addition, around 55% of furniture and furnishings are being sublet to new tenants of the space they are moving from. If we only account for the items being reused in their new facility we wouldn\'t be able to achieve the requirements of credit MR 3.3. However, salvaging and reusing furniture and furnishings (per the intent) reduces demand for virgin materials, as well as diverts materials from the landfill. Does this cohesive strategy meet the intent of credit MR 3.3?" "While the strategy adopted for the use of the used furniture is commendable, only furniture that is reused for the specific project can be accounted for in MRc3.3 calculations. Applicable Internationally. " "None" "None" "X" "LEED Interpretation" "5279" "2008-01-10" "Commercial Interiors" "MRc3.2 - Materials reuse - furniture and furnishings" "Our client is planning to reuse existing office equipment (e.g. computers, printers, and copy machines). These items are in use in their current space and the owner plans to move them to the new space. While old equipment may not be operationally energy efficient, unless it is ENERGY STAR, reusing it does save energy and other resources by reducing the demand for new machines. By extension, reusing products and materials supports solid waste management goals. The itemized list in CSI MasterFormat Division 12 does not specifically include any computer/electronic equipment. Furthermore, given your emphasis above, ""reducing impacts associated with the extraction and processing of virgin resources,"" please clarify the following. 1. Will the reuse of existing office equipment (e.g. computers, printers, and copy machines) help contribute in achieving LEED-CI MRc3.3? 2. What is the definition of a workstation?" "No, computers and other electronic equipment cannot be included in the calculations for MR Credit 3.3. This credit is based only on items covered under CSI MasterFormat Division 12 as stated on page 231 of the LEED-CI v2.0 Reference Guide. Please refer to page 232 for a list of typical items that may be included under this credit. A workstation can be panel-based, comprised of modular interconnecting panels, hang-on components, and drawer/filing components or a free-standing grouping of furniture items with components that have been designed to work in concert.
