Operating question
The Chariho pilot focused on whether a targeted self-renewing air cleaning system could support environmental readiness in a school setting and how that intervention should be understood alongside other operating layers.
What Metalmark did
- Evaluated Tatama® in a school pilot environment.
- Connected intervention performance to a broader view of environmental strategy.
- Documented findings in a downloadable case study PDF for stakeholder review.
What changed
The Chariho case study reports classroom particle-removal performance and modeled energy implications from using localized air cleaning alongside ventilation strategy.
Up to5xMore effective than ventilation alone for particle removal.
Up to34%Reduction of sub-0.5 micron particles in 5 minutes.
Up to57%Modeled classroom heating energy reduction.
Why it matters
Schools and campuses need practical, defensible decisions across complex occupied environments. The Chariho case shows how one intervention can fit into a broader readiness and verification framework.
