## Operating question

In a high-ventilation operating environment where persistent environmental challenges remained unresolved, the team needed to understand whether a targeted intervention could improve measured conditions and create evidence decision-makers could use.

## What Metalmark did

- Established a baseline for the operating environment.
- Deployed a self-renewing air cleaning system as a targeted intervention layer.
- Measured and documented performance during the operational period.

## What changed

The live case study reports measured reductions across multiple environmental indicators during the pilot period.

**Up to67%** Reduction in non-ideal PM2.5 levels.

**Up to29%** Reduction in TVOCs.

**Up to38%** Reduction in bacteria.

## Why it matters

The case demonstrates how Metalmark frames intervention as part of a measured system: baseline first, targeted action second, documented improvement third.
