Modernization of Zoo Zagreb, Phase I

The problems that were to be solved are: inadequate space to accommodate desired animal species, fulfilment of EU requirements, inability to expand in an existing location, insufficient infrastructure and supply in existing facilities (parking lot, toilet, restaurant, ticket office, walking paths, educational center), lack of administrative capacity. Green infrastructure were implemented. It is a green wall, which we use to promote green infrastructure. Within the building, larger glass surfaces, which become a danger to birds, are specially marked. Hot water heaters were installed. The project created a housing for animals "Large aviary for African birds". Above the inner part, there is a large green roof, with which we have reduced the cost of heating and energy losses. In addition to this system, a water biofiltration system was built and is in operation in the outer part of the house. Using a pump, water from the smaller lake is pumped into the area where the reeds grow. Given that the water is loaded with organic bird waste, in this way, through water circulation, water hygiene is ensured, unpleasant odors are avoided. Over 80 trees and several hundred pieces of different bushes were also planted. Stakeholders of the project were city administrative bodies, Zagreb Zoo, Zagreb Tourist Board, citizens, tourists, competent state administration bodies, non-governmental organizations dealing with environmental and nature protection, and animal protection.
