What percentage of space must be audited for achieving IEQ Credit Green Cleaning-Custodial Effectiveness Assessment?

To achieve the IEQ Credit for Green Cleaning – Custodial Effectiveness Assessment, the standard requires that a minimum of 10% of the building’s occupied space be audited. This auditing process is crucial as it enables the evaluation of the effectiveness of the cleaning programs and processes in place.

By focusing on a percentage of space that allows reasonable representation of the entire facility, the assessment helps identify areas needing improvement in maintaining indoor air quality and cleanliness, which directly impacts the health and comfort of the occupants. Conducting audits on 10% ensures that the evaluation is substantively reflective of the overall custodial practices while remaining manageable in scope for the auditing team.

Adhering to this requirement is essential for not just achieving LEED certification credits but also for reinforcing best practices in sustainable cleaning that contribute positively to indoor environmental quality.
