This document summarizes an energy benchmarking analysis of two paper supply stores. Key findings include: 1) Phoenix store uses more energy per square foot than Tempe store and benchmarks. Both could benefit from changing lights from 32W to 28W bulbs. 2) Switching bulb types would save an estimated $709 annually for Phoenix and $432 for Tempe, with a payback period of 2-2.5 years. 3) Actual savings after the change were greater at $2,019 for Phoenix and $1,378 for Tempe, achieving a return on investment in under 12 months for both stores.

10. Energy Benchmarking | Recommendations
10
• IFMA standards for energy efficiency state that energy usage should be between 5
kWh/FT2/Year and 20 kWh/FT2/Year
• Phoenix is an energy waster, however they are open on Saturdays while all other
locations are closed. Recommend de-lamping and changing all light bulbs from 32w to
28w.

12. Lamp Replacement | Expected Benefits
12
Recommendations
• Change light bulbs in both locations and de-lamp where possible.
Expected Benefits
• Replacement of bulbs in Phoenix and Tempe will result in annual
savings of $709, $432 respectively.
• De-lamping will provide additional savings commensurate with amount
of lamps taken out of use.

13. Lamp Replacement | Results Tracking
• Utility Bill 2014 vs. 2013
13
• We anticipated yearly savings to be $ 709 in Phoenix and $ 432 in Tempe. Actual savings was
$2,019 in Phoenix and $1,378 in Tempe.
• Cost of the project in Phoenix was $1,455.44 and $1081.92 in Tempe. We were able to achieve an
ROI of less than 12 months in both instances.
