Page 1 IceCold Pilot Study

Page 2 Pilot Candidate: Siemens 501 Fountain Parkway 32 RTUs provide cooling to 170,000 SF of Office and Production Spaces 21 of these RTUs are Electrically Fed from 2 Dedicated Electrical Panels Pilot Test: Introduce IceCOLD Catalyst to these Units While Logging Electrical Consumption of the Dedicated Panels Before and After Installation 2 Sources of Heat Gain: Internal (Manufacturing/People – Fixed / Constant Load) and External (Weather Based) Compare Normalized Electrical Consumption of Pre- and Post- IceCOLD Addition Pilot Study Overview

Page 3 Concept: Evaluate kWh / CDD Before and After Installation Isolate RTUs to be Monitored 3 rd Party Electrical Monitoring – Pre and Post Installation Track Local Weather Variables (Min/Max Temp, CDD) Confirm No Significant Variance Production Loads Validate Strong Relationship Between Electrical Consumption and Weather “IMVP Option B” Compliant M&V Methodology Strong Correlation with Weather Dranetz PX – 5

Page 5 Under Sized Systems – If systems are undersized for the space / application served and cannot meet set points, then reductions in compressor cycling may not occur (although the space condition may improve). Implemented Control Strategies: Strategies such as free cooling (economizers) or temperature setbacks, etc, may reduce the impact of the savings potential. “New” vs. “Old” Equipment: New equipment has less fouling, potentially reducing the impact of the catalyst. (Many Panel 2 RTUs are recent replacements; Panel 1 RTUs >15 Years Old). New equipment more likely to include economizers, etc. For M&V: Must “Isolate” the equipment for comparison (so loads aren’t “shifted” from monitored units to others), account for all cooling loads (variability), show strong correlation for comparisons. Considerations for Future Candidates
