Summary

LED Canopy Lighting

Canopy Lighting: LED vs. HID

Exterior ceiling mounted luminaire for gas station canopies.

Synopsis:

Exterior gas station canopy lighting is an application where LED products are gaining traction. LED canopy lights can replace the traditional HID lights, providing equivalent illumination and reduced energy consumption.

Outdoor lighting luminaires employing LED technology are widely available from a number of manufacturers. The U.S. Department of Energy (DOE) is encouraging research, development and market penetration of the technology and is providing resources for objective, ongoing information about the technology. Of the almost 4,000 products listed in the DOE LED Lighting Facts database as of December 2011, over 700 (18%) are commercial outdoor products.

Energy savings over traditional canopy lighting may be significant—up to 30-75% depending on original light levels, technology and controls. Lamp life could be significantly longer than other systems in use, making it especially good in hard-to-access locations. The white light is available in a range of color temperatures and light distribution can be more precisely controlled, often providing more uniformity than most other technologies. Additionally, the DOE predicts continued improvement in efficacy and decline in price for LED lighting.

Baseline Example:

Baseline Description: Service station with MH canopy lighting
Baseline Energy Use: 30091 kWh per year per unit

Comments:

A lighting upgrade project at a service station consists of replacing 15-400W metal halide(MH) “shoebox” fixtures with 15 light emitting diode (LED) Canopy fixtures.  The MH fixtures draw 458 Watts of input power each while the LED fixtures require only 122 Watts each. There is no HVAC interaction as the canopy lights are exterior and thus located in an area with no heating or cooling requirements. The power (kW) reduction is simply 15 x (458 W –122 W)/1,000W/kW = 5.04 kW.  The lighting is controlled by a photocell and operates 12 hours per day for 52 weeks per year.  The annual energy savings are 5.04 kW x 4,380 hours/year  = 22,075 kWh of on-site energy savings.  Assume a savings or power reduction of 5 kW per service station. 

The baseline annual energy use is 0.458 x 15 x 4,380 hours/year = 30,090 kWh/year.

Manufacturer's Energy Savings Claims: Currently no data available.
Best Estimate of Energy Savings:

"Typical" Savings: 73%
Energy Savings Reliability: 6 - Approved Measure

Comments:

Savings range 30-75%. Assumes changing current lighting to LED. This is already in the BPA Lighting Calculator, so we rated the ESR 6.

Energy Use of Emerging Technology:
8,124.6 kWh per unit per year What's this?

Energy Use of an Emerging Technology is based upon the following algorithm.

Baseline Energy Use - (Baseline Energy Use * Best Estimate of Energy Savings (either Typical savings OR the high range of savings.))

Technical Potential:
Units: unit
Potential number of units replaced by this technology: 4,859
Comments:

According to the U.S. Census Bureau, there are about 121,446 gas stations in the U.S. http://www.statisticbrain.com/gas-station-statistics/  Prorating by population (the Northwest region has about 4% of the U.S. population) suggests that there are about 4,859 gas stations in the Northwest. 

Regional Technical Potential:
0.11 TWh per year
12 aMW
What's this?

Regional Technical Potential of an Emerging Technology is calculated as follows:

Baseline Energy Use * Estimate of Energy Savings (either Typical savings OR the high range of savings) * Technical Potential (potential number of units replaced by the Emerging Technology)

First Cost: Currently no data available.

Cost Effectiveness:

Simple payback, new construction (years): N/A

Simple payback, retrofit (years): N/A

What's this?

Cost Effectiveness is calculated using baseline energy use, best estimate of typical energy savings, and first cost. It does not account for factors such as impacts on O&M costs (which could be significant if product life is greatly extended) or savings of non-electric fuels such as natural gas. Actual overall cost effectiveness could be significantly different based on these other factors.
