Improve operational reliability? Reduce operational cost? Improve lab/workspace environment?  Identify impact on labs and occupants (+/-) Workmen in the labs/workspaces Temperature/humidity conditions Effect of final result of the project  Safety concerns  Funding sources and incentives  Payback on investment  Image 2

Proprietary & Confidential Impact of Dynamic Control on Dilution Rates 1.5 L spill of acetone in 200 sq ft lab room, 1 sq. m spill After vaporized, dynamic system hits TLV in 20 vs. 60 min After 2 hours dynamic control has dropped level to 2.6 PPM – After 2 hours, 6 ACH system is at 302 PPM or 116 times higher! Dynamic control approach is always less than 6 ACH baseline 15 min. detection time still better than 6 ACH baseline! Lower initial ACH helps!

Proprietary & Confidential Lighting Retrofit Objective 18 The objective of the this project is to optimize fixture spacing in lab spaces to provide an average illuminance on the desktop/bench top of 50 foot candles and 10-20 foot candles on non-working surfaces. In so doing we intended to reduce total lighting consumption by 50%.
