Green Building Standards

Green Building Practices

As The Greenest Zoo in America®, all new habitats are built to Leadership in Energy & Environmental Design (LEED) standards.

Sustainability brags include:

The Zoo partners with the Metropolitan Sewer District to divert all of the rainwater that drains into the site off the storm water grid. Phase I alone replaced more than one acre of pavement with an acre of green space. Upon completion of Africa, nearly eight acres of green space have been added, which takes one-third of the Zoo’s storm water off the grid. Pervious concrete, bio-swales, and a large rainwater re-use tank are used to pump out the water for irrigation.

Going for Gold

Phase III of the Africa exhibit, which includes naturalistic spaces for lions, cheetahs, painted dogs and mixed hoof stock, achieved LEED Gold certification in part due to what’s under the exhibit.  A 400,000-gallon underground detention tank below the painted dogs collects rainwater that’s filtered and used to feed the streams, waterfalls and tanks in Africa and other Zoo exhibits.

Contributing Green Features

Other green features that contributed to gold certification include:

  • Restored a once-asphalted parking lot into a natural habitat (hauled off 3700 tons of asphalt, which was able to be reclaimed)
  • Capturing and reclaiming rainwater for reuse (this water is held in the 400,000 gallon reservoir under Painted Dog Valley).
  • Water use reduction thru draught tolerant plants and efficient plumbing fixtures (faucets, toilets, waterless urinals)
  • Energy efficient buildings
  • Diverted over 95% of the construction waste to recycling centers and away from landfills
  • 12% of materials used were recycled
  • 56% of materials used were regional
  • Used solar tubes for natural lighting of the animal holding areas
  • Used low VOC materials on the interior of the buildings
  • The Base Camp Café is the Greenest Restaurant in America as determined by the Green Restaurant Association.

The solar array over the Zoo’s exemplary parking lot provides 20% of the power for the exhibit/restaurant. Learn more here.  

Cincinnati Zoo Connections to Africa

Dung research in Kenya

The Zoo partners with the African Conservation Centre in Kenya. The Centre’s primary aim is to bring together the people and skills needed to build East Africa’s capacity to conserve wildlife.

The Centre is located in the South Rift Valley of Kenya, stretching from the Maasai Mara National Reserve through Amboseli National Park, and is one of the most spectacular wildlife areas on the planet. Each year, the Zoo, in conjunction with Miami University’s Project Dragonfly, leads an Earth Expeditions course titled Kenya: Wildlife & People in Integrated Landscapes. Up to 20 teachers, primarily from the United States, travel to the South Rift Valley to engage in community-based conservation in this dynamic landscape. This effort builds on the decades-long research of Dr. David Western, former head of the Kenya Wildlife Service, and the centuries-long research of the Maasai pastoralists, who have long co-existed with wildlife in an open grassland ecosystem populated by elephants, lions, giraffes, zebra, wildebeests, and a remarkable diversity of other species. With the rise of nontraditional lifestyles, private ranches, and fenced lands that prevent needed wildlife migrations, communities of the South Rift have recognized the need to understand the impact of these changes and to work together for a better future.

100% of Proceeds Support Olkiramatian Women’s Group in Kenya

While in the AFRICA exhibit at the Zoo visitors will have an opportunity to help one of our conservation mission’s back in Africa. Beaded bracelets, made by the Olkiramatian Women’s Group that manage the Lale enok Resource Center in the South Rift of Kenya, are being sold in the AFRICA exhibit. These bracelets are an unchanging symbol of the Maasai – a tangible cultural icon and a means to maintaining healthy livelihood. The Lale enok Resource Center provides the community with important information including good places to graze cattle, recent lion activity, water sources, etc. The Resource Center also houses lion conservation research teams that track and follow the resident lion prides using GPS collars provided to them by the Zoo.

These collars help the researchers alert the community about where the lions are, which helps the herders keep their cattle safe and reduces the number of lethal conflicts between lions and humans. So, they also protect lions. The Women’s Group not only uses money from the sale of bracelets to support the Resource Center (and hence the lion research), but also to support tuition for Maasai girls at local schools. The Resource Center focuses on improving human health and livelihoods while also helping protect wildlife.

“The bracelets are a symbol of the coexistence of humans and wildlife – and the Zoo wants to inspire it’s visitors with this message of coexistence in hopes that they will take the sustainability and conservation messages they hear at the Zoo and put them into place in their homes and communities,” said Maynard. “By purchasing a bracelet, Zoo visitors are supporting the coexistence of lions, humans, and other wildlife in the South Rift.”

The Zoo has a long-standing partnership with the Cheetah Conservation Fund (CCF). Founded in 1990, the CCF’s mission is to be the internationally recognized center of excellence in the conservation of cheetahs and their ecosystems. Each year, the Zoo, in conjunction with Miami University’s Project Dragonfly, leads an Earth Expeditions course titled Namibia: Great Cat Conservation. Up to 20 teachers, primarily from the United States, travel to CCF headquarters in Namibia, which is home to the largest wild population of cheetahs. Loss of habitat and available prey, competition with other predators, conflict with farmers and ranchers, and poaching are taking a heavy toll on wild cheetah populations. Students engage in ongoing research projects at CCF, which include radio tracking, cheetah physiology, ecosystem management, and the design of school and community programs.

From a tall watchtower on the edge of Mbeli Bai, a large swampy clearing in the Congo rainforest, researchers observe how gorillas interact with each other and their environment. The Zoo supports the the Mbeli Bai western lowland gorilla study, located in the Nouabalé-Ndoki National Park. Initiated in 1995, it is the longest-running field study of western lowland gorillas in the wild. Led by Principal Investigator Thomas Breuer, the study provides unique insights into gorilla social organization and dynamics, which are critical to determining the best course of action for gorilla conservation. In addition to scientific study, the researchers also talk to the community about the importance of gorillas. Through Club Ebobo, local children are learning – and helping their parents learn – that over-hunting for bushmeat threatens the survival of gorillas and the health of the forest as a whole. The Zoo’s Primate Center Team Leader, Ron Evans, has traveled to the Congo to assist with the Mbeli Bai study and its educational outreach efforts.
