Air Change Rates – What the team found • No codes, just guidelines • No Standard Industry Practice • Questioned client’s standard for air change rates in laboratories • Higher Rates Alone DO NOT EQUAL Assured Effective Ventilation Payette Associates Princeton Guyot Hall Addition Labs 21 Phone Forum - August 2003
Air Change Rates – Design Process • Baseline Criteria - Initial Model – Based on client standard of 10 Air Changes – Effectiveness – Layout • Intermediate Modeling – 6 Air Changes – Diffuser Locations – Effectiveness • Final Model – 8 Air Changes – Diffuser Locations – Effectiveness – Client Responsiveness Payette Associates Princeton Guyot Hall Addition Labs 21 Phone Forum - August 2003
