How Chariho evaluated an energy-saving IEQ strategy

eventtion could support classroom conditions while reducing reliance on energy-intensive ventilation...

VENTILATION

ALONE

LOCALIZED AIR CLEANING
!

Classroom conditions and energy assumptions measured and analyzed against operational baseline.

KEY FINDINGS

Up to

34%
reduction of sub

0.5 μm particle in 5 minutes

Up to
5x more effective than ventilation alone for particle removal

Up to
57%
modeled classroom
!

heating energy reduction

Why it mattered

The district needed evidence that indoor environmental quality and energy goals could be addressed together, without adding classroom disruption.

What this made possible

A more evidence-based path for evaluating ventilation, air cleaning and energy tradeoffs in occupied classrooms
