Description
Applicable Scenarios
Credit SN-2 credit is an example of the
complications that can arise when pursuing the
Credit SN-2 is used in the Office Building/Full
LEED recycled content material and regional
Faade Renovation scenarios 4B (Silver) and 6B
harvesting credits simultaneously. In the Office
(Gold).
Building "Full Faade Renovation" scenarios, it is
assumed that "synthetic" gypsum wallboard (with
90% or greater post-industrial recycled content) is
procured to achieve credit MR-4.2 (recycled
content for 10 percent of the total value of
materials). However, since the plants that make
this high recycled content gypsum wallboard are
limited, it assumed that the material is shipped
from beyond a 500 mile radius of the site. This
disqualifies the gypsum wallboard from applying to
the Regional Material credits (MR-5.1 and MR-5.2).
To achieve the MR-5.2 material extraction credit, it
is therefore assumed that a regionally
manufactured ceiling tile is procured. For the
purposes of the study, it is assumed that the raw
materials for the ceiling tiles are obtained within a
500 mile radius of the site. A cost premium is
defined based on the assumption that the regional
ceiling tile manufacturer may not be the low bidder
for the project.
Two credits are achieved with the SN-2.
Basis for Cost Assumption
The synergistic cost for credit SN-2 is defined as
the individual credit cost of MR-4.2 / Full Faade
(which is the premium to use synthetic gypsum
wallboard) plus a premium for purchasing
regionally-produced acoustical ceiling tiles.
