- All large-diameter wood used is recycled timber, pillars and doors from nearby abandoned farm buildings or from houses damaged by an earthquake that shook Masaya, Nicaragua in 2002.
- Principal wall material is brick fabricated in La Paz Centro, 50 km away
- No pesticides needed to treat wood because all new and recycled wood is naturally resistant to termites and powder-post beetles
- Roofing is a combination of fiber cement sheets and clay tiles made in La Paz Centro
- Solar panels supplement power from the traditional grid
- With vaulted ceilings and strong cross-ventilation, the building stays cool without fans or A.C.
- No lightbulbs needed during the day, thanks to skylights and large windows oriented east-west
- Users and staff live close enough to walk or ride in on a motorcycle
- The roof helps capture rainwater during the rainy season and stores it in a large tank. The stored water is gravity-fed to our gardens and used to clean the building.
- Toilets are water-less latrines
Grounds and gardens:
- Native tree species were planted to reduce erosion from the steep slope below the library building
- The wooded grounds and gardens connect the library with the forested El Nisperal Private Reserve, home to howler monkeys and 120 species of birds, including thirty migratory species.
