Is it a requirement for the April 2012 template to use all materials ( we are not using Div. 12 materials) across the template for Recycled Content, Regional Materials, and Certified Wood? Under L-3 we have listed all materials we are using and some do not contribute credits to 4, 5 or 7. We have a figure for total materials cost but does that mean that all materials listed including Div. 12 materials are to be listed under L-3? Some materials like iron fencing do not use wood but it is local and pre-consumer recycled so do we list that for MR 7 too?
