The town of Hohen Neuendorf constructed a three-grade primary school with a 3-field sports hall for combined school and after-school use with integrated catering in a passive house style. The planning team designed the building based on a low-cost/low-tech approach, aimed at creating a school with the lowest possible life-cycle costs suitable for sustainable operation. It is achieved through a balanced combination of natural processes and passive technologies with few simple and low-maintenance active technical components. Pellets are used as a renewable energy source for heat generation, a cogeneration plant and extensively used photovoltaic facilities enable a positive energy balance and CO2-neutrality.
