Why It Matters

Labs exhaust large volumes for safety, creating a heavy conditioning load. Recovery lowers that load while maintaining the strict air changes required.

Typical Energy Savings

Sensible recovery on make-up air commonly removes 50 to 70 percent of the heating and cooling demand.

Recommended Technology

• Plate cores where airstream isolation is mandatory
• Run-around or coil systems for contaminated exhaust

What to Watch

• Never mix fume-hood exhaust with supply air
• Balance energy savings against safety and containment
