Current Environmental Sustainability Practices at DC Libraries

Go Green LogoRoof Sundolier at P.S. Miller LibraryDouglas County Libraries just got a little brighter, and a little greener! Through a donation from the Sunflower Corporation, they installed a Sundolier™ daylight system for no cost at the Philip S. Miller Library. Using solar power and a battery, the Sundolier™ will actually follow the sun, tracking its brightest angle, and disburse the natural light through the main room of the library. This should help reduce electric light and cooling demands, and related emissions. It is the latest of many environmental sustainability practices Douglas County Libraries incorporates to save energy and money.

Air Quality

  • Many Douglas County Libraries employees work a flexible schedule that allows them to work 4 ten-hour days, saving them a full day of commuting.
  • Using Douglas County Libraries web-based Intranet, many employees put in several hours of work from home, sparing our environment the emissions they would use commuting to work.
  • Many employees of Douglas County Libraries participate in Webinars to further their training as an alternative to driving to a training site.
