MATERIALS AND RESOURCES and Restoration Materials and Resources Credit WASTE REDUCTION PERFORMANCE MRc1 1–12 points
废弃物减量绩效 MRc1 1-12分
To prevent waste and reduce the amount of materials from building operations and maintenance disposed of in landfills or incinerators.
防止浪费并减少建筑运营和维护活动中被填埋或焚烧的材料数量。
Waste Diversion 1–12 Divert materials generated from building operations and maintenance activities from reaching landfills, incineration (waste-to-energy), or other disposal methods. Diversion includes strategies such as waste prevention (reduction), reuse, recycling, or composting. Points are awarded according to Table 1.

Track waste generation monthly and include the material type and weight of all nonhazardous solid materials. Track or estimate variations in materials management that occur outside the reporting period, such as seasonal collection or intermittent waste streams. Calculate waste diversion by tracking the amount of materials (by weight) diverted from landfills and incineration. For diverted materials, specify the diversion method (reduce, reuse, recycle, compost, etc.). If material quantities are estimated, provide the methodology and/or source references used to make calculations. If actual weights are unavailable for certain material types or hauling methods, volume-to-weight conversion average values can be used. To calculate the overall diversion rate, divide the weight of materials diverted by the total weight of materials generated for the same reporting period. Account for seasonal collection or intermittent waste streams within the calculations. See Equation 1 for the waste diversion calculation: Equation 1.
