Wilhelm-Raabe-Schule: Building Automation System Installation for Attic Conversion

The Wilhelm-Raabe-Schule attic conversion project in Lüneburg, Lower Saxony, Germany requires a contractor to supply and install a complete building automation system (BAS). This involves integrating controls for both HVAC and underfloor heating systems. A significant component of the work is the management of a new air handling unit with a capacity of approximately 7,000 cubic meters per hour. The system must also implement CO2-based demand-controlled ventilation specifically designed for classrooms and other spaces within the converted attic. This implies the need for CO2 sensors, sophisticated control algorithms, and potentially integration with existing school building systems, although this is not explicitly stated.

The project's complexity lies in the integration of multiple building services, the demand-controlled ventilation aspect, and the potential need to interface with an existing building management system. Without details about the age and type of existing system (if any), the integration effort remains uncertain. While the brief describes a 'system installation', the scope may encompass the design, programming, commissioning, and documentation of the BAS. The 'electrical' trade suggests this tender is for installation only, but this would need verification. Contractors should clarify the exact scope prior to bidding. The lack of a published deadline means actively pursuing this tender through direct contact with the school or relevant authority is essential.

The fact that this is for a school attic conversion hints that space might be restricted for equipment installation and wiring runs. CO2-based demand-controlled ventilation also suggests a need for meticulous calibration and potential ongoing maintenance requirements to ensure optimal air quality and energy efficiency. Finally, contractors must confirm they meet all relevant German electrical and building regulations.
