The cost of this credit is project-specific.
OPTION 1: DIVERSION
See MRp2: Construction and Demolition Waste Management Planning.
OPTION 2: REDUCTION OF TOTAL WASTE MATERIAL
A requirement to not generate more than 2.5 pounds of construction waste per square foot of the building’s floor area could reduce construction costs, at the expense of more time and attention for careful quantity take-offs and ordering, and ultimately front-end consideration for waste reduction efforts through the design of the building.
Anything one throws away on the job site is something that was purchased, transported, and handled. Realizing that “‘waste” equals “dollars” will generate project-specific cost savings, dependent upon construction methods and building type. Modular construction and prefabrication lend themselves towards achieving high levels of waste reduction.
Because this credit option is new in LEED v4, there aren’t yet a lot of case studies (and cost data) from projects pursuing this kind of strategy.
