* Recirculation efficiency could not be measured for System consisted of central air handler and fan-filter units cascading through four rooms. Average 0.49

* Recirculation efficiency could not be measured for System consisted of central air handler and fan-filter units cascading through four rooms.

Best practice topics Yellow - completed White - planned Cleanroom Best Practices Topic Organization

Demand Controlled Filtration Benchmarking confirmed large energy savings by setting back recirculation air Pilot Studies confirmed ability to control based upon particle concentrations Market is skeptical

Fan-filter unit testing Testing 2’x4’ units Performance curves based upon pressure rise, airflow, and fan kW Goal is to integrate results into deployment programs

Minienvironment studies Study of energy performance of one minienvironment suggests performance can be improved Study of cleanroom using many minienvironments addresses overall energy performance
