We have Project intending to be registered under LEED 2009 BD+C for major renovations. This is an existing building which will undergo major renovation work for the interiors, HVAC and a large extent of the external façade (structural systems).
Following is the query related to the Materials category:
Should the documentation for the credits i.e. Construction Waste Management, Recycled Content, Regional Materials, Rapidly Renewable and Certified Wood, only focus on the renovations or should it also include the portions of the existing building.
You rely on LEEDuser. Can we rely on you?

JP - You inquiry is a little unclear. What do mean by "only focus on the renovations or should it also include the portions of the existing building"? Do you mean there are portions of the existing building that are not being renovated and do you have to deal with existing materials for the MR credits?
Here's some general info: The MR credits apply to all activities within your LEED project boundary. The MRc3-7 credits address purchases made for the LEED project.

Thanks for the reply. What I would like to clarify is:
1. When we do credit calculation for MR Credit 2: Construction Waste Management, should we include waste details at the time of construction of existing building, which happened around 10 years back and details are not available as of now. Only waste management details of renovation that is going to happen will be available. So the scope of MR CR 2 calculation is for the entire building or only for renovation works is the specific query that I have.
2. Similarly for MR CR 4 and MR CR 5 will the calculation include material cost details of existing building materials (steel, concrete, cement etc.) details of which are difficult to obtain at this time, if these are to be included it will be difficult to achieve credit points for MR CR 4 & 5 as these materials constitute a major chunk of the total materials cost.

JP - A LEED project covers the extent of the project that is currently being undertaken. In the case of an existing building being rehabilitated under LEED BD+C: NC, you are only dealing with waste generated and materials used for that renovation project - not the original construction of the building. You do NOT have to go back in history to get information on the existing building.
