The Denver Public Library is serious about sustainability. We look daily for ways to reduce our consumption of resources, use renewable resources, reduce our pollutants and create alternative methods for connecting people with materials.

The Denver Public Library’s Green Achievements
- Reuse of material is what libraries do. Reusing material saves the cost of producing the material. In 2009 we had 638,169 customers who borrowed 9,681,017 items.
- 58 million online transactions in 2009. This includes access to the catalog, articles, books, audio books, and videos. Customers can enjoy library resources from the comfort of home or office.
- Interlibrary Loan and Prospector services fielded 283,287 requests to borrow and loan materials from libraries nearby and around the world.
- Two Reading Rocket bookmobiles provide weekly bookmobile service to 31 Denver Public Schools. In 2009, over 4500 children received library cards through the bookmobile and checked out over 60,000 items.
- In partnership with Xcel Energy, the Denver Public Library has added portable Watts Up? meters to our circulating collection. Accurate and easy to use, these meters have helped hundreds of individuals and businesses save energy and make appliance decisions.
- Eco-friendly book bags! The Denver Public Library is pleased to announce this option for transporting your library materials. This reusable tote is made from recycled materials and can be recycled at the end of its life. Available at all locations for $1.
- The Booklovers’ Ball went green. The event featured some of the latest ideas in green event planning, including an opportunity to purchase carbon credits for travel to and from the event, low impact event invitations, décor, catering supplies, locally grown food, local organic wine and other environmentally friendly programs.
- In April and May of 2007, Fresh City Life devoted a month of programs to Greenprint Denver, culminating in an event with Academy Award winning producer and climate change activist Laurie David.
- 15% of staff participate in the RTD Eco-pass program and many more bicycle and walk to work each day.
Greener Library Buildings
- In 2007, Denver voters approved funding for 3 new branch libraries. These new buildings will be LEED Silver certified.
- Better Denver Bond funded improvements and renovations:
- Upgraded mechanical/electrical systems
- New A/C systems and/or HVAC units at four libraries
- New boilers at four libraries
- New building automation systems at five libraries
- Upgraded electrical distribution systems at seven libraries
- At all 23 library locations, the temperature set points are maintained between 68 and 74 degrees. We heat up to 68 and cool to 74.
- Eight locations have digital controls to control the temperature set point.
- Two locations have digital lighting controls and are able to set a lighting schedule.
- Infrared motion sensor lighting installed where possible.
- Three locations have HVAC equipment rated at 85% efficient. (Hampden, Barnum and Bear Valley)
- The HVAC replacement at Woodbury Branch Library is rated at 90% efficient.
- 19 locations have energy efficient lamps and ballasts.
- We use low VOC (volatile organic compound) painting practices. VOCs produce a volatile gas when applied, diminish air quality, and may be detrimental to health.
- Carpet replacement projects use Interface eco-friendly carpet; no glue, no VOC, recycled content.
- Waste carpet from the carpet replacement projects are sent to a carpet recycler.
- Facilities methods and practices directed toward green compliance; cleaning products are eco-friendly when possible, rags are laundered for reuse and we use microfiber mops and walk-off mats at all entrances.
- Replacement countertops are solid surface and/or solid wood surfaces instead of laminate.
- Full participation of all 23 libraries in Denver’s recycling program.
Energy and Emissions
