Energy Independent School Ostrog

The most beautiful school in Croatia that wants to become one of the first energy independent schools in the world. The school is already famous for a botanical garden that is cared for by a student environmental cooperative. Its students and teachers are now seeking to become Croatia’s first energy-independent school. To recall, the Ostrog Primary School, with the help of crowdfunding campaign on Indiegogo platform, and with the support of the Energy Cooperative Kastela and the United Nations Development Program (UNDP) in Croatia has collected USD 10,000. These funds have been added to the funds of UNDP, donations from the county and the local community and the investment from the private company Eco - Orbis Ltd. through ESCo model, so at the end, the total amount invested in the energy independence of school exceeds USD 115,000. One part of donated funds were invested in thermal insulation and waterproofing of the roof and on the replacement of classroom lighting with more efficient LED lighting should reduce power consumption more than 60 percent. The legal standard of required illumination is also achieved in the school because it protects the health of children in a crucial stage of their development.
