Intent

To track and reduce the waste that is generated by building occupants and hauled to and disposed of in landfills and incinerators.

Requirements

Have in place storage locations for recyclable materials, including mixed paper, corrugated cardboard, glass, plastics, and metals. Safely store and dispose of batteries and all lamps (indoor and outdoor, hard-wired and portable fixtures).

Track and measure all ongoing waste and durable goods waste.

Measure the total weight of waste (in lbs., kg, or tons) that is generated, and the total weight that is diverted from landfills and incineration facilities for one full year or from a waste analysis. Exclude any facility renovations waste.

Input generated and diverted waste totals into the Arc platform, and calculate a Waste Performance Score for the project. Obtain a minimum Waste Performance Score of 40. Additional points for this prerequisite are awarded for Waste Performance Scores above 40, according to Table 1.

Waste Performance Score

The waste performance score rates the waste generated by the building against the waste generated by comparable LEED certified buildings.

The score is a value from 1-100 based on the project’s total weight of waste generated and the total weight of waste diverted from landfills and incineration facilities.

Waste Performance Score calculation

To calculate waste performance score, the following data is required:

  • Total waste generated (lbs., kg, or tons)
  • Total waste diverted (lbs., kg, or tons)
  • Weighted occupancy

The waste generated is converted into an average daily waste generated per occupant, using Equation 1.

Equation 1. Average daily waste generated (Adwg) = the sum of waste generated readings within the last 365 days (∑1≤d≤365wg)/ the number of days the readings belong to ∑≤d≤365 d where
d=number of days where there are readings

Example:
A building conducted a waste audit over a 1 week (7 day) time period. The results of the audit showed that

  • 200lbs of waste were generated
  • 150lbs of waste was diverted
  • Occupancy 40

The daily waste generated is converted into a daily waste generated per occupant using Equation 2.

Equation 2. Average daily waste generated per occupant (Adwg/o)= the output of Equation 1. /occupancy (TOcc)

Example continued:

The daily undiverted waste is calculated using Equations 3-5.

Equation 3. Average daily waste diverted Adwd = the sum of waste diverted readings within the last 365 days ∑1≤d≤365wd / the number of days the readings belong to ∑1≤d≤365d

Example continued:

Equation 4. Average daily waste diverted per occupant Adwd/o = the output of Equation 3. / total occupancy TOcc

Example continued:

Equation 5. Average daily undiverted waste per occupant Aduw/o = the output of Equation 2 Adwg/o – the output of Equation 4 Adwd/o

Example continued:

The project’s calculated average daily waste generated per occupant AND average daily waste undiverted per occupant are input into the waste scoring function to calculate the waste performance score.

The waste scoring function was developed using waste information reported by LEED buildings certified under LEED O+M v2009. The data set includes buildings that pursued MR credit 6. Solid waste management – waste stream audit.

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.
