We have very high (54%) local materials component for MR 5.1 well above the 20% requirement. This is largely due to two major materials manufactured locally - if we removed these materials we are still well in excess of the 20% requirement. One of these materials is the grass/gravel pave system which was manufactured in Denver. We introduced this company to a local company who manufactured the product for us locally and will now be the Canadian manufacturer of the product. The environment and economic impact of encouraging this to happen is obvious. The problem is that this material does not have raw materials harvested in it within 500 miles. As such, if we took the two large materials out of the 5.1 calculation we would meet the leed requirement for both 5.1 and 5.2. If we leave it in the 5.1 requirement is at 54% but 5.2 drops to 38%. This seems counter productive. The question is if we have bought products that manufactured locally do we have to include them in the 5.1 calculation if we already met this requirement so that it does not negatively impact the 5.2 calculation. It seems a little silly not to have bought these two products locally so we could get two points rather than 1point. We believe we have sufficient innovation credits and we feel that we should get the 5.2 credit based on what we achieved. Further we ask for clarification on what is meant by harvesting, extracting or recovered materials from 500 miles. To be specific if we buy a local rubber flooring product made of 100% recycled rubber does the recycled rubber component count as a extracted, harvested, or recovered material as the manufacturer obtains the recycled rubber within 500 miles of the product? The same applies for BC gypsum board which contains a recycled component of gypsum? They obviously qualify for the recycling content calculation but I am not sure whether you can also count it towards the 5.2 credit.
Our recommendation is to highlight the local/regional materials to total at least the required 20%, simply leaving out the materials that have non-locally harvested content. If the remainder of the materials have locally harvested content meeting the 50% requirement, as you mention they do, the credit should be achieved. Your efforts meet the intent and the requirements for both portions of the local/regional materials resources credit, and should be rewarded by receiving points for both. There is the option of applying for an innovation credit citing "exceptional performance" by exceeding the credit requirements for MRc5.1 by a large amount. However, as you mention having sufficient innovation credits, this would not be practical. Harvesting, extraction and recovery of materials: In response to your second point regarding the harvest, extraction and recovery of materials within a 500-mile radius, it applies to credit 5.2 IF the materials are obtained within that circle of 500 miles. Therefore, if the rubber flooring is made from 100% recycled rubber and the manufacturer obtains the rubber from a recycling facility within 500 miles (disregarding the original source), it would count towards this credit because it would be harvested from a local source. The same does apply to recycled gypsum board - if it is made from material that has been recycled within the 500-mile radius, it is considered to be locally harvested. The intent of this portion of the credit is to ultimately reduce the environmental impact resulting from transportation and to support local economies; therefore, even though some materials have an origination outside the 500-mile radius, their use as materials in a "new" product encourages a local manufacturing economy, thereby reducing the costs and environmental impacts associated with the transportation of newly manufactured items.
