17 Iconic Portland Buildings Went Lights Out to Fight Light Pollution

On September 15, 17 iconic Portland buildings turned off their unnecessary lights, taking part in the 2017 launch of the Audubon Society of Portland’s Lights Out campaign, an effort designed to encourage Portlanders to save energy, save birds and see stars. Households and businesses pledged to turn off their non-essential lights from dusk until dawn, and then to go outside to gaze at the night sky.

On September 15, 17 iconic Portland buildings turned off their unnecessary lights, taking part in the 2017 launch of the Audubon Society of Portland’s Lights Out campaign, an effort designed to encourage Portlanders to save energy, save birds and see stars. Households and businesses pledged to turn off their non-essential lights from dusk until dawn, and then to go outside to gaze at the night sky. This event marked the start of Portland Audubon’s effort to address the growing issue of light pollution in the Portland metropolitan region.

The Portland cityscape looked different on Friday night thanks to participating iconic buildings including the Oregon Convention Center, Fox Tower, Park Avenue West, OMSI, 1201 Lloyd, Bonneville Power Administration, 200 Market, Lloyd 700 Building, Lloyd Tower, Metro Regional Center, the 911 Federal Building, East West College, the Bank of America Financial Tower, Montgomery Park, 1900 Building, the Portland Building, and Holladay Park Plaza. The Lloyd EcoDistrict cosponsored the launch event with their own district-wide effort, #LightsOutLloyd, which included 9 of the participating buildings!

“This year, we had more participating buildings than ever, with 17 buildings enrolled on the 15th to help raise awareness about the hazard that lighting presents to  migrating birds!” said BirdSafe Campaign Coordinator Mary Coolidge. “Hundreds of people have enrolled in our Take the Pledge program since our launch in July,  which demonstrates the huge interest that people have in the issue of light pollution.”

In addition to the citywide effort, over 500 people pledged to go lights out for the night, over 415 of which have Taken the Pledge to Go Lights Out, which is a long term commitment to reducing light pollution. These folks pledge to do a simple home lighting audit and to write to regional decision makers encouraging them to adopt policies and goals to reduce light pollution. They also receive a Take the Pledge to go Lights Out sign to put up in their front yard to help raise awareness about light pollution!

Portland Audubon has long been concerned about light pollution, which drowns out the stars that birds use to navigate while migrating, and lures them into cities where they are at risk of colliding with windows. Across the United States, up to 1 billion birds die every year as a result of hitting a window. What’s more, nearly 80 percent of North Americans, including Portlanders, live in places from which they cannot see our home galaxy, the Milky Way.

In addition to environmental and cultural impacts, light pollution can impact human health. Emerging research suggests links between blue-rich white light and a variety of human health concerns including sleep interruption, impaired daytime functioning, damage to the human eye, melatonin suppression, and increased risk for breast cancer, diabetes, and cardiovascular disease. In June, the American Medical Association (AMA) adopted official guidance encouraging municipalities to follow good lighting practices in street lighting selection in order to “minimize potential harmful human and environmental effects.” Light Emitting Diodes (LED) have tremendous energy efficiency benefits, but LED’s that emit blue light have potential to impact health and safety when used as streetlights and in other outdoor settings.

How can community members get involved in the Lights Out Campaign:

1. Turn out all unnecessary lighting from dusk until dawn, enjoy the stars and and help raise awareness about light pollution!

2. Do an audit of outdoor lighting at your business or home:

  • Turn off outdoor lights when you’re not using them
  • Make sure that all outside lights point down
  • Convert lights to motion sensors so they are only on when needed
  • Make sure that lights are well-shielded so that they don’t create glare
  • When converting to LED, make sure to select warm bulbs (under 3,000 Kelvins)
  • Talk to your employer/building manager about minimizing unnecessary overnight lighting.
  • Turn off or dim rooftop lighting, decorative lighting, lobby and atrium lighting

3. Make an extra effort to minimize nighttime lighting during bird migration periods:

  • Fall Migration Dates: August 25 to November 15
  • Spring Migration Dates: March 15 to June 7 

4. Support public policies that minimize light pollution

  • Audubon’s LightsOut PDX campaign is working to promote policies and practices that reduce light pollution in the Portland metropolitan area. Click here to Take the Pledge.
