Assessment Instructions

Intent: What is the purpose of this indicator?

This indicator assesses the entity’s strategy for managing construction and demolition waste. A structured approach helps reduce the amount of waste sent to landfills or incineration by prioritizing recovery, reuse, and recycling of materials.

Input: How do I complete this indicator?

Select yes or no. If yes, select all applicable sub-options for (1) management and construction practices (2) end of life embodied carbon of building materials and (3) on-site waste monitoring.

Terminology

Audits

A systematic review and assessment performed by qualified personnel to determine by investigation, examination, or evaluation of objective evidence, the adequacy and compliance of the contractors with the sustainability-specific requirements.

Construction waste signage

Visible signage that clearly indicates the process of properly dealing with waste generated during construction.

Diversion rate requirements

Requirements to meet a specified diversion rate which is materials diverted from landfill, incineration (WTE), and the environment / total generation.

Education on waste management

Educating employees, contractors and crews on materials recovery techniques and procedures, such as sorting and storage methods, recoverable materials and removal techniques.

Hazardous waste

A solid waste, or combination of solid wastes, which because of its quantity, concentration, or physical/chemical/infectious characteristics may either cause, or significantly contribute to an increase in mortality/serious irreversible illness. Hazardous waste might also pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, disposed of, or otherwise managed.

Incentives for contractors

Incentives, for example, to allow contractors and crews to retain a portion of revenues and/or savings from materials recovery and sales.

Management and construction practices

Measures and strategies implemented by management and construction employees throughout the construction project.

Non-hazardous waste

Waste that does not have the potential to cause harm to humans, animals or the environment.

On-site waste monitoring

Monitoring of waste generated during the design and construction phase of the building, to identify that waste generation and disposal objectives are being met.

Recovering building materials

Diverting building material waste from landfill by recovery of the material from site to be recycled or sent for energy recovery.

Recycling building materials

Diverting building material waste from landfill to an on or off-site recycling facility.

Reusing building materials

Diverting building material from landfill by reemploying the material on site or on other approved sites in the same or related capacity as their original application.

Waste management plan

Plan that addresses the collection and disposal of waste generated during construction or renovation, usually including the collection, transfer, treatment and disposal of a variety of waste types.

Waste separation facilities

A designated facility where waste is separated into different elements to be correctly disposed of, recycled, or otherwise managed.

Waste stream

The complete flow of waste from generation to final disposal.

Validation: What evidence is required?

No evidence required. Only the 'Other' answer is manually validated.

Other:

1. Other: State the waste management practice.

2. Other: State the type of waste monitored.

It is possible to add multiple other answers. If multiple other answers are acceptable, only one per sub-option will be counted towards scoring.

Validation Basics

Scoring

Scoring: How does GRESB score this indicator?

The scoring of this indicator is equal to the sum of the fractions assigned to the selected options and respective sub-options, multiplied by the total score of the indicator.

Other: The 'Other' answers are manually validated and assigned a score which is used as a multiplying factor, as per the table below:

Validation status	Score
