Parking garages shine a light on energy conservation

The lights are always on in parking garages, so increasing efficiency makes a big difference. In the coming months, lighting in several Portland State parking garages will be updated with high efficiency LED fixtures, resulting in cost savings, energy use reductions, and increased security. 

“LEDs give us the unique opportunity to meet several goals at once,” said Sarah Renkens, transportation and parking services manager. 

Energy Trust of Oregon, a nonprofit organization dedicated to helping utility customers benefit from saving energy, is partially funding projects in the Fourth Avenue and Blumel Residence Hall garages. 

Upon completion, the new lighting in the Fourth Avenue garage is estimated to save about $18,000 each year. The new LED light bulbs are more than twice as efficient as the old metal halide light bulbs.

In addition to cost and energy savings, the new LED light fixtures will require less maintenance than current systems while providing brighter light. Older bulbs, like those used in the Blumel garage, emit a dull orange glow, while LEDs are much brighter, enhancing general visibility and security in the garages.
