Primary school with after-school club and sports center near Berlin
Low cost in the long run
Task
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.
Building characteristics:
- U-values of the windows < 0.8 W/m²K
- U-values of the opaque envelope < 0.15 W/m²K
- Thermal-bridge-free structure
- Airtight building envelope n50 < 0.6/h
Building performance:
- Heating need < 15 kWh/(m²a)
- Primary power demand < 0 kWh/(m²a)
- CO2 emissions < 0 kg/a
GFA: 7,400 m²
Production costs: € 2.2 million (technical building equipment)
