Passive house standard at Diesterweg school, Osnabrück
Climate-friendly construction and optimal indoor air quality
Diesterwegschule
The Diesterweg School in Osnabrück, an open all-day primary school, has been expanded with a state-of-the-art sports hall and a cafeteria with 120 seats. The two-year construction period resulted in a pioneering project that meets the highest energy standards. Of particular note is the realisation of the sports hall to Passive House standards – a clear demonstration that climate-friendly construction is not only feasible but essential today.
Energy efficiency
Significant reduction in energy consumption through cutting-edge Passive House technology.
Superior air quality
Two Menerga Adconair 76 units (5,000 m³/h each) ensure optimal indoor air quality. Certified by the Passive House Institute (PHI).
Innovative technology
High-efficiency counterflow heat exchangers for maximum energy recovery. Integrated pressure control and seamless connection to building management systems.
Project description
Sustainable design
)
Sports hall
The new sports hall was constructed using a timber structure on a reinforced concrete base, complemented by a sleek wooden façade. This design seamlessly combines aesthetics with sustainability.
The Passive House construction significantly reduces energy consumption, marking a key step towards greater climate protection. For the students, this means not only an environmentally friendly setting but also an inviting atmosphere with optimal indoor air quality.
)
Cafeteria
Additionally, the new cafeteria, with seating for 120, enhances the school’s offering for all-day students, balancing energy efficiency with modern design.
Perfect balance of energy efficiency and performance
Technical equipment
To meet the strict requirements of the Passive House standard, two Menerga Adconair 76 air handling units were installed. These dual-axis systems provide an air volume flow of 5,000 m³/h each, ensuring exceptional indoor air quality. Certified by the Passive House Institute (PHI), these units are equipped with highly efficient counterflow plate heat exchangers that minimise heat losses while maximising energy recovery.

Advanced technology for optimal performance and seamless integration
Key technical features
High-efficiency counterflow exchangers made of polypropylene
Designed for maximum energy recovery, they are distinguished by low internal pressure losses.
Dynamic volume flow adaptation
Advanced external volume flow controllers enable flexible adjustment of airflows to meet varying occupancy and usage demands, ensuring energy efficiency without compromising comfort.
Precise pressure control
Integrated duct pressure sensors continuously monitor pressure conditions and automatically adjust airflow rates to ensure stable and efficient operation at all times.
Seamless integration with building management systems
Using the BACnet protocol, all operating parameters can be monitored and controlled in real-time.
Future-oriented approach: A model project combining aesthetics, energy efficiency and sustainability.
