This is a performance-based prerequisite that must be documented through the Arc platform. There are two parts to the prerequisite—an occupant satisfaction survey and indoor air quality testing. These components roll up into a single “human experience” score.

This credit requires you to develop and implement an ongoing indoor air quality (IAQ) management program, with the intent of maintaining good IAQ and avoiding complaints and air quality hazards.

The credit should be no- or low-cost to implement, and is non-technical in nature. Any project team would do well to consider attempting it.

I-BEAM is the basis of the credit

Central to the credit is the U.S. EPA Indoor Air Quality Building Education and Assessment Model (I-BEAM).

To earn this credit, 75% of your cleaning products and materials purchases must meet the credit criteria. You can earn exemplary performance if 100% of your purchases meet the criteria.

This prerequisite lays the groundwork for achieving the green cleaning credit. There are two options for complying with the prerequisite. The first is to develop and implement a green cleaning policy. The second is to use a certified cleaning service.

This prerequisite lays the groundwork for achieving the EQ credits for green cleaning.

There are two options for complying with the prerequisite. The first is to develop and implement a green cleaning policy. The second is for using a certified cleaning service, which is new compliance option in LEED v4.

This credit covers materials purchased for both renovations and routine maintenance. There’s no minimum scope of work for this credit, so remember to include all materials purchased to maintain your building (e.g. paint touch-ups) in addition to products purchased for renovations or fit-outs.

Purchases for all maintenance and renovation activities (environmentally preferable and not) must be tracked. Teams must track relevant purchases made by both the building management and tenants during the performance period.
