For significant savings, consider new high-efficiency lighting, HVAC equipment and other measures. New equipment requires a larger investment up front, but it usually pays for itself through energy savings in just one to four years. Paybacks are averages and may vary based on your operations.

Cash incentives from Energy Trust of Oregon and any available tax credits may help cover costs and reduce payback periods on many measures.

If major energy improvements stretch your budget, check out the Oregon Energy Loan Program from the Oregon Department of Energy. The program offers low-interest loans for energy conservation, renewable energy and other projects.

Typical measures and payback periods*
Replace T12 fluorescent fixtures with high-performance T8 lamps and electronic ballasts and save 40 percent or more: 2- to 4-year payback.

Consider ceramic metal halide track lights for a good point source spotlight that offers good color rendering, increased energy savings and long lamp life. Simple screw-in models make installation easy: 2- to 3-year payback for screw-in CMH and 5- to 7-year payback for CMH fixtures.

Consider colored LED lights for window displays. According to a study by the Lighting Research Center, these tiny lights use 30 to 50 percent less energy than traditional window-display lighting, yet create visual interest that appeals to shoppers: 3- to 5-year payback.

Install LED exit signs and save 90 percent over incandescent signs: 2- to 3-year payback.

Install occupancy sensors on lights in storage rooms, conference room, restrooms and other appropriate areas: 2- to 5-year payback.

Install a demand-controlled ventilation system that adjusts based on store occupancy: two- to four-year payback.

When purchasing new equipment, upgrade to a high-efficiency air handler or chiller: 2- to 4-year payback.

When purchasing new equipment, upgrade heating, ventilation and air conditioning controls: 2- to 4-year payback.

Even if you lease your space, discuss upgrades with your landlord. You may even team up to share costs on energy upgrades; you’ll benefit from a more inviting retail space, and it increases the value of the property for the landlord.

*Your actual results will vary based on energy use and energy-efficiency measures.
