4 SMARDT chiller performance curve

5 Red line represents probable power line if only one chiller in operation Settled out at 1120 Power 368 kw Peak power at 377kw at 1240 Started chiller #1 at 1240 (Two chillers operating) Power settled back down to ~325kw ~0830 Started chiller #1 (Two Chillers Operating) 1040 Secured chiller #1 Power: 324 kw just before

6 Just before turning chiller #1 off at Left both CW pumps and both CDW pumps running to get a comparison with only the chiller being secured.

7 Just before starting #1 back up again.

13 Jimmy Pastor Hangar Manager, Corporate Real Estate Hawaiian Airlines Hangar Lighting Retrofit

14 CHARLES I. ELLIOTT MAINTENANCE & CARGO FACILITY Located at Daniel K. Inouye International Airport 283,000 square-foot office & industrial facility Supports 24-7 Operations for Hawaiian Airlines Maintenance & Engineering, Cargo, Fleet Service, Supply, and Claims departments Equipped with energy efficiency systems

15 ISSUE DEFICIENT LIGHTING IN HANGARS Light levels from the 6-Lamp T5HO fluorescent fixtures did not meet specifications Location # of Fixtures* Req. Illumination (IES/BOD) Avg. Illumination** Maintenance Hangar fc 45.0 fc Cargo Hangar fc 41.4 fc *Original fixtures are 6-Lamp T5 HO Fluorescent consuming 360-watts **foot-candle (fc) measurements taken using calibrated light meter at 30-inches above floor Proper lighting is crucial to night operations Safety of personnel and equipment Aircraft maintenance and inspections Maintain productivity

16 Lighting Measurements in Deficient Spaces

17 OPTIONS CONSIDERED Option #1: Add 40% 6-Lamp T5 HO Fixtures Install 172 more fixtures to existing system Installation assumptions - Lower material cost, Higher labor cost 40% Higher electrical and maintenance costs over life of system Higher load on Emergency Generator Option #2: Retrofit existing fixtures to LED One for one replacement of fluorescent fixtures Installation assumptions Higher material cost, Lower labor cost Lower or same electrical costs. Lower maintenance cost over life of system Lower load on Emergency Generator

18 Data Analysis Base case and Options were analyzed for costs & benefits Case Total kw Utility Cost Maint. Cost Simple Payback Base Case $249,778 $25,000 N/A Option #1 Add Fluorescent $349,226 $30,000 No Option #1 Fluorescent w/ Controls $254,145 $30,000 No Option #2 Retrofit to LED w/ controls $118,379 $1, yrs. Option #2 Retrofit to LED was the value option

20 PROJECT OUTCOMES Project successfully addressed deficient lighting Reduced electrical and maintenance costs by >55% Reduced generator emergency load by 20 kw Qualified for > $100,000 Rebate from Hawaii Energy

21 CONCLUSIONS Focus on life cycle for long term solutions Hawaii Energy may have tools to assist you explore options and solutions A dollar saved in operating cost, is equal to one dollar of profit to your organization

22 Dissecting the Data Dan Mestas, VP Engineering Bank of Hawaii Corporate Real Estate & Facilities

23 kw per ton ON load Two chillers = Total plant kw/ton of 0.85 Three chillers = Total plant kw/ton of 0.74

24 kw per ton OFF load Condenser not matching load due to being constant flow

25 kw per ton OFF load - continued The plant has CTs on all four condenser fans Compiled interval data from EMS Used COUNTIF= to count all non-zeroes Divided this by total number of data points to arrive at a load factor, in this case, 47% So roughly two of four fans are always running The fan laws would tell you it is more efficient to run all four fans at 50% than two fans at 100% 4 x (50%)^3 versus 2 x (100%) 75% reduction in fan energy!!!

26 What else is incentivized? Engage your local energy engineering contractor and Hawaii Energy rep to do a site visit Example: We found there was an incentive to implement Demand Controlled Ventilation for our kitchen downtown Project Cost: $22,000 Annual Savings: $5,000 Incentive: $10,000
