I have a rectangular desk and a semi-circular corner desk in the same line by the same manufacturer and wanted to know if these 2 desks counted as different products for the materials calculations? They look different in that the corner desk is twice as large as the rectangular desk, so according to the LEED Reference Guide, this could maybe qualify as a different "function" instead of just an "aesthetic" difference, but I wasn't sure. The best/closest example I could find in the LEED Reference Guide was the one about a desk chair vs. a side chair counting as 2 different products, but a desk chair with arms vs. a desk chair without arms wouldn't.
