Story at a glance:

  • Snøhetta and Stantec designed the Charles Library so natural light reaches 90% of its occupied areas.
  • The Austin Central Library achieved LEED Platinum in 2018 after its completion in 2017.
  • William Rawn Associates renovated the 1895 Boston Public Library with LED lights, low-flow plumbing, and more.

Every book you can imagine, access to endless information, community services—what do you think of when you think of a library today? What about green libraries?

Modern libraries are so much more than places to check out books, though they’re certainly that, too, and we’re grateful. But some of the best libraries are also community spaces, acting as hubs for cultural programming, education, children services, and more.

As anchors in their cities, libraries new and old should also be built to last. We’ve come to depend on these institutions all over the world, and architects have told us it’s become increasingly important that the design of these buildings be sustainable.

But what is a green library exactly?

According to the International Federation of Library Associations, green libraries are “designed to minimize negative impact on the natural environment and maximize indoor environmental quality by means of careful site selection, use of natural construction materials and biodegradable products, conservation of resources, and responsible waste disposal,” and that’s just to begin with.

We think the best libraries should also stand the test of time, built with sustainable building materials that are durable.

Some of our favorite green libraries also incorporate clever daylighting solutions, have multiple methods of bringing the community together, incorporate energy-efficient HVAC, and more. These are some of our favorite standout green libraries.

Snøhetta and Stantec designed Temple University’s new Charles Library, completed in August 2019, with an impressive green roof and expansive atrium lobby, all set on a textured granite base.

The four-story, 220,000-square-foot library has natural light in 90% of its occupied areas, reducing the amount of artificial light required.

“Snøhetta was looking for large glazed windows to increase the transparency of looking into the building. The side benefit of that is that we’re bringing in natural light to 90% of the occupied areas,” Scott Sullivan, principal architect at Stantec, told gb&d.

“All of our lighting inside the building has either a combination of photoelectric sensing or occupancy sensing. If it’s a nice sunny day, the lights won’t turn on. If it’s a cloudy day or night, the lights will then turn on based on occupancy or darkness levels.”

Daylighting is also emphasized at the LEED Platinum Austin Central Library, designed by Lake|Flato and Shepley Bulfinch.

The 198,000-square-foot facility has a six-story atrium at its core that provides daylight to more than 80% of the library’s regularly occupied spaces.

“The presence of daylight makes people feel happy and more productive. It makes people want to be there,” David Lake, principal in charge for Lake|Flato, told gb&d.

Before ever breaking ground the architects made models to explore light in the space.

“We took the models outside and tried all different configurations. We wanted to harvest the light evenly around the building without glare but still have a library that could be flexible in the future,” Lake says. “It was our biggest challenge.”

Beyond natural light, of which there is also plenty in this renovation, you’ll find a beautiful 1895 building with surprisingly modern amenities and sustainable design, thanks to William Rawn Associates.

Completed in 2016, the renovation shows us what historic libraries can be, with a design that both preserves history while also becoming a community hub with multiple, updated entrances. A light-filled space spills out into a new public plaza, complete with Wi-Fi and outdoor seating on one of Boston’s liveliest thoroughfares.

“This project creates a new civic idea for public libraries—with a heightened sense of being open, welcoming, and seamlessly connected to the city streets,” Cliff Gayley, principal architect on the project, told gb&d in the initial interview.

Beyond new LED lights and increased daylight all around, the design team also installed low-flow plumbing fixtures, occupancy sensors, and VAV (Variable Air Volume) boxes to reduce energy and conditioned air usage as part of the project.

In Oklahoma, the reimagined Tulsa Library includes updated HVAC alongside historic spaces as MSR renovated the building to bring it into the 21st century.

“The historic quality of the space was important and the detail it carried. There were a lot of great things we did not want to lose,” says Dagmara Larsen, project manager at MSR, in an interview with gb&d.

The team worked to maintain the look of the existing 145,000-square-foot structure as much as possible by keeping the roof, balcony, entryway, and other aesthetic details the same. They added glass study cubes to the balcony to increase daylight, utilizing a space that was once unusable.

Now the HVAC system runs on frictionless bearing chillers, a heat-recovery chiller, and dual wheel ventilation air handlers. A fully automated lighting system utilizes daylight harvesting, scheduling, and vacancy and occupancy sensors.

In Bogotá the BiblioRed project got off the ground with services at the Virgilio Barco Library, designed by Rogelio Salmona S.A., and other libraries., in the eary 2000s.

“They made four big libraries in parks in areas that used to be dangerous or for lower income people,” saso María Elvira Madriñán, widow of famous Colombian architect Rogelio Salmona and herself a leader in architecture, share with gb&d. “[Before] there was one library downtown. Many kids didn’t have the access to go downtown to the library, so these projects started to give the kids the possibility to access to books and culture.”

Madriñán says the great network of libraries managed to have wide coverage, complemented by a network of small libraries in schools and colleges to reach all of the city.

The Virgilio Barco Public Library was built inside a park designed by Salmona, with pedestrian and bike paths, canals, lakes, and native trees. In addition to being a place of learning and community, the project emphasized the issue of water management. The UNESCO World Heritage Centre site makes great use of rainwater by integrating it into the building. According to UNESCO, the project challenges the concept of contemporary public space as it incorporates meeting places and open access so all can enjoy the space, whether they want to take a walk in nature or go inside and read.

6. Tianjin Binhai Library

Incredible daylighting and two rooftop patios make this library in China stand out.

The Tianjin Binhai library is truly a green library that makes you stop and stare, asking, “Was this made for Instagram?” as it’s almost too beautiful not to photograph.

Designed by MVRDV and the Tianjin Urban Planning and Design Institute, the 363,000-square-foot space was commissioned as part of a plan to create a cultural district in the city. The library is surrounded by four other cultural buildings, all connected by a glass-covered public corridor. A public park sits in front of the library.

Terraced bookshelves wrap the walls while also being represented on the outside—each level doubles as a louvre, allowing light and air to flow through. Glass walls in the front of the library open to the park outside to allow for nature views and enhanced daylight.
