While I recognize that laundry detergent is not part of this credit, I see a comment in this thread stating that you could make a case to add it. The person asking the question was working with a hotel, which I am as well right now. Laundry detergent is not only a enormous part of their budget, but they are looking to replace the entire system. While they already use laundry waste for irrigation, the new system will save more energy and water. ANYWAY, there are no GS-51 laundry detergents that have been approved or Ecologo. EPA's DfE program, however, has listed laundry detergents. So two things: 1) they want to switch to a better product in support of LEED but if they aren't going to get to "count it", and they are spending more money on the product, it's going to be tough to explain to the client later and 2) they are asking my opinion of the new system including what products could be used, and I back to the dilemma that comes with question #1. Thoughts are appreciated! Thanks!
