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" "1547" "2006-07-29" "Commercial Interiors" "The project team took great care in selecting construction materials in order to attempt MR Credits 4, 5 and 6. With the exception of MR Credit 4 Recycled Content, the team\'s efforts will be for naught if furnishings are required to be included in the calculation of these credits. All major office furniture manufacturers are centrally located on the continent, most typically in Michigan and Ontario. Therefore, the manufacturers are not within a 500 mile radius of the project, as the tenant\'s headquarters is located in Vancouver, British Columbia. Another point to consider is that at the time the furnishings order was being finalized, wheat fiberboard plants were closing across North America. So although the team\'s intention was to use wheat fiberboard as a worksurface substrate, there was not the volume of board available to fulfill the large order. In the LEED-CI Pilot version, the inclusion of Division 12 Furnishings in the calculations of the Materials & Resources credits was optional. Division 12 (Furnishings) Material Value will skew the project\'s Materials & Resources (MR) calculations. Can we have the option to exclude Division 12 from the MR calculations, as long as we are consistent across the credits?" "The request to exclude Division 12 from the MR credits as described in the Inquiry is not allowed. While the rationale presented is compelling, this concept was debated and ultimately rejected by committee prior to balloting LEED-CI. Applicable Internationally; Canada."

The University will be dedicated to the research of alternative fuels and renewable energy. The entire campus will be New Construction on a Greenfield site and will consist of research labs, lab support areas, administration buildings, a library, a commons building, food service, an auditorium, conference rooms, lecture halls, offices and public areas. Regionally manufactured building materials are not readily available due to the project location and unoccupied nature of certain areas of Saudi Arabia. Only a small portion of the building materials can be obtained within 500 miles. As a result, a good majority of the materials that will be acquired for the project will be delivered by sea from adjacent countries. Similar conditions exist in Canada. The unoccupied regions of Canada influence the availability of building materials and methods to transport those materials. These conditions have allowed the Canadian LEED rating system to implement a larger distance allowance for the regional materials Credit. Different modes of transport have different fuel efficiencies in transporting goods. LEED Canada-NC 1.0 acknowledges these differences by extending the permissible transportation distance to 1500 miles for those goods transported by rail or by ship. Truck - 2127 KJ/ton*km Rail road - 373 KJ/ton*km Shipping - 138 KJ/ton*km The intent of this Credit is to ""reduce the environmental impacts resulting from transportation."" The above transport options show significant reduction in energy and fossil fuel use for rail and boat transport. Due to the project site conditions and site transport options, our project is seeking interpretation to use the Canadian requirements for the Regional Materials Credits. The Canadian requirements can be found below. Please advise on our project\'s ability to use this interpretation. Canadian LEED NC 1.0 Regional Materials Requirements Use a minimum of 10% / 20% of building materials or products for which at least 80% of the mass is extracted, processed and manufactured within 800 km (500 miles) of the project site. OR Use a minimum of 10% / 20% of building materials or products for which at least 80% of the mass is extracted, processed and manufactured within 2400 km (1500 miles) of the project site, and shipped by rail or water. OR Use a minimum of 10% / 20% of building materials or products that reflect a combination of the above extraction, processing, manufacturing and shipping criteria (e.g., 5% within 800 km (500 miles) and 5% shipped by rail within 2400 km (1500 miles))." "This CIR is requesting that the project be permitted to substitute the existing MRc5 credit requirements with those found in the Canadian Green Building Council LEED Rating System. The CAGBC LEED requirement allows for materials to be harvested from a larger area (1500 mile radius) if it reaches the site by lower emission transportation (ship and rail.) While the proposal certainly aims to reduce the environmental impacts resulting from material transportation, it does not address the portion of the credit aimed at supporting the use of indigenous materials. Furthermore, the CAGBC LEED rating system has been developed specifically for the Canadian construction and transportation industries, and it may not be appropriate to use it in place of the USGBC requirements as applied on this Jeddah, Saudi Arabia site. However, the intent of the project to reduce the emissions associated with the transportation of materials is commendable and should be pursued as an innovation point. As such, the credit submission should include a narrative explaining local common practices for transport of materials and how this strategy surpasses those for environmental benefit. Resources on past innovation points that have been pursued for Life Cycle Analysis can be found in the Innovation in Design Credit Catalog, issued on 12/7/07. The USGBC also anticipates that credit requirements for comprehensive carbon emission reduction on a building project will be available by the end of the year. If the construction schedule permits, this could be an option for the project to receive credit for their efforts. Applicable Internationally; Canada; Saudi Arabia.
