TABLE 5.E.3 Project C&D Debris Table

10. You set up a C&D debris program at your site and recycle all the cardboard, gypsum wallboard,
steel, concrete and brick, and wood for a new construction project. Your dumpster count at the end
of the project is as listed in Table 5.E.3. Calculate the percent recycled C&D debris by both volume
and weight using the LEED conversion factors. With the weight calculation how many LEED 2009
points might you obtain? With the volume calculations how many LEED 2009 points might you
obtain? With the volume calculations how many LEED 2009 points might you obtain?

11. You are putting up a new building at a currently vacant site. You set up a construction debris
program at your site and recycle all the cardboard, gypsum wallboard, steel, concrete and brick,
and wood for a new construction project. Your dumpster count at the end of the project is as listed
in Table 5.E.3. Calculate the percent recycled C&D debris by both volume and weight using the
Columbia, S.C., study dumpster densities. With the weight calculation how many LEED 2009
points might you obtain? With the volume calculations how many LEED 2009 points might you
obtain?
12. You are planning to start designing a project, and the site engineer asks how and where the
C&D debris area should be located. Using the six categories given by LEED for typical conversion
factors, estimate dumpster sizes needed and the footprint on the ground needed for this C&D
debris recycling area. Make a sketch of the footprint. Make sure that proper access is available to
the location for both the recycling contractors and the workers, and sketch in these accessways.
Be sure to include fencing as needed.
13. Total construction cost of your new building on a site (project C) with no demolition is $15,000,000,
and Table 5.E.4 represents the materials tracked as applicable to MR credits 3 through 7. This table does
not represent all the materials used, only those tracked for LEED purposes. All new wood and all
the furniture items are listed. Include the listed furniture items (wood furniture and workstations)
in the calculations.
A. Calculate the LEED 2009 eligible points based on Table 5.E.4 for MR credits 3, 4, 5, 6, and 7.
B. Is this project eligible for any LEED 2009 EP points as related to MR credits 3, 4, 5, 6, and
7. Why?
