Regional Materials - Mileage Info

Mike, For clarification I assume you mean "numerous locations" for recovery of scrap to make new steel? If that's the case, it sounds like 47% of the weight of the materials were sourced/recovered from within a 500 mile radius of the project site. Some steel producers track incoming scrap (i.e - the step just prior to melting the scrap into new semi-finished steel products) by mill and by zip code. It's possible that any steel fabrication can be made up of steel from several mills, but not typical. The LEED 2009 addenda includes language whereby you can use the 'scrap recovery' locations or the location of steel mill melt shop. So ultimately the value you should submit is 47% of the total value of the steel product. In other words, if you have $100,000 of steel delivered to the project from a final manufacturing location which is within 500 miles from the project site, you'd include $47,000 as the regional material value.
