Here is a another link to leed and clay points

http://www.americanclay.com/leed

From vinyl siding to clay you can find material that fits into LEED certification. Is there products that do not fall into the certification or comes with very small points? They all add up to the 90-129 points needed. It now becomes a juggling act to find the products with more points. So, if you build a very simple building with very few products you will not reach the grade needed to certify. Is that a problem? If so, go out and purchase more products and systems to reach the grade.
