Sustainable DPL
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, 2007
- Reuse of material is what libraries do. Reusing material saves the cost of producing the material. In 2007 we had 530,368 customers who borrowed 9,517,573 items.
- 43,052,707 online transactions. This includes access to the catalog, articles, books, audio books, and videos. Customers can enjoy library resources from the comfort of home or office.
- 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.
- The bookmobile service checked out 33,052 items to patrons who are not able to access a local library. The bookmobile has 19 stops near schools and senior centers.
- 86 employees (nearly 20% of staff) participated in the RTD value pass program.
- Interlibrary Loan and Prospector services fielded over 250,000 requests to borrow and loan materials from libraries nearby and around the world.
Greener Library Buildings
- In 2007, Denver voters approved funding for 3 new branch libraries. These new buildings will be LEED Silver certified.
- At all 23 library locations, the temperature set points in building 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 scheduled 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
- Library users can request most items in the collection be delivered to their local branch, saving a trip across town.
- In 2001, purchased one hybrid vehicle.
- Three delivery trucks run on biodiesel B20 fuel. Plan is to consider this option on all future purchases.
- Redesigned daytime delivery routes resulting in mileage and fuel use reduction.
- Redesigned routine facilities maintenance schedule routes resulting in mileage and fuel use reduction.
Water conservation
- Reduce water usage by replacing, as needed, the tank type toilets with low flow toilets.
Recycling
- In 2003, started recycling office waste paper and cardboard.
- 1st quarter 2007 all locations participate in Denver’s single stream recycling program.

Reduce paper use
- In 2006, software implementation reduced paper use from 5,000 sheets of paper to 1500 sheets every 2 weeks in the Interlibrary Loan department.
- Two Branch locations use print release stations for public printing, reducing unnecessary printouts and wasted paper. Customers are able to select the printouts they need and specifically which pages to print.
- Electronic distribution of in-house data reports.
- Electronic customer notification. On average, we electronically notify 3000 patrons each day regarding holds, overdues, etc.
- There are 40,044 subscribers to 23 different online newsletters, keeping people informed while saving paper and postage.
