EBOM-2009 MRc1: Sustainable purchasing - ongoing consumables 1 point

Applicants are required to address all tenant spaces for all performance period building management and operational purchases in the building as they pertain to LEED-EB. This includes both sustainable and non-sustainable tenant alternative material purchases under MRc2. If tenants control some aspect of purchasing products in any of the categories relevant to this credit, the preferred approach is to acquire purchasing data from them and incorporate it into the calculations. If tenant purchasing information is not available, LEED-EBv2.0 allows an alternative approach that allows building applicant to still pursue MRc2 by assuming that all tenant purchases are non-compliant through the following methodology: 1. Calculate purchase rate of MRc2 products on floor area basis for the Applicant controlled building space Purchases [$ per SF] = (APPLICANT MRc2 product purchases [$] / APPLICANT floor space [SF]) 2. Use purchase rate from Step 1 to project purchase rate [$] in TENANT spaces Projected TENANT MRc2 products purchases [$] = (Purchases [$ per SF] * TENANT floor space [SF]) 3. Inclusion of project purchases in Step 2 in calculating the percent of compliant purchases for the whole building (With Inclusion of Non-Compliant Tenant MRc2.1-2.5 product purchases) APPLICANT MRc2 compliant purchases (%) = ((APPLICANT Compliant MRc2 product purchases ($)) / (APPLICANT total MRc2 products purchases ($) + Projected TENANT MRc2 products purchases ($))) Applicable Internationally.

In a contiguous multi-building or campus environment within a single geographic region it is permissible to assign organization-wide purchases to specific buildings based on a square-footage analysis if those purchases inherently scale with building square footage with only a weak dependence on how each building is used. For example - if the campus as a whole purchases $1,000 in adhesives and sealants, the applicant may assume that a building representing 24% of the total square footage of the campus \'purchases\' 24% of those materials ($240), and calculate compliance with EB MRc3 accordingly. A similar procedure could be followed for furniture and furnishings in EB MRc2. However, quantities of office paper in MRc2 and mercury lamps in MRp2 and MRc6 depend strongly on the usage type of each space, and in these cases the Applicant needs to either prorate based on a different metric or provide evidence that prorating by square footage is reasonable (e.g., if virtually all buildings have a similar usage type, if exceptions or corrections are made for major variances, etc.). As the Applicant noted, specialty purchases should be assigned on a building-specific basis whenever feasible, and any extenuating circumstances which might suggest alterations to the square-footage analysis should be considered and documented accordingly. Calculations based upon a per student or per occupant basis would not be permissible unless the Applicant showed that the purchases inherently scale with the number of students or building occupants. Applicable Internationally.
