Fundamental Redevelopment of the Federally-Owned Property
In 2001, the entire control technology of the federally-owned property was replaced. The property, located in Heinemannstrasse 2-10 in Bonn, was also equipped with modern technical building services.
In both of these different projects, the following features are included:
- new user requirements
- energy security/security of energy supply
- renewable energy supply
- considering environmental pollution and operation management
- technical building services are included in a BMS-system according to "Wonderware"-standards; plans are made according to calculations of current and target states
Old technical systems are replaced by more efficient ones. New energetic concepts were designed according to which the high-rise buildings A1 and A2 are not fully being air-conditioned. The use of cooling and heating surfaces in the ceiling leads to a more efficient and future-oriented way of conditioning the building. The supply is managed by water coming from an existing well. Due to the use of insulated surfaces on the façade according to ENEV-standards, the overall energy use of the property is reduced by 50%. The new BMS-system manages approx. 12.000 data points. The building project was split up into three major construction phases. A great part of the employees working for the German Federal Ministry of Education and Research were relocated to Berlin; approx. 700 employees of the Federal Ministry had been working during the redevelopment.
The replacement of the old measurement and control technology, as well as the BMS-system including the installation of heating, ventilation, air-conditioning and sanitary facilities has almost been completed. The project run by the Federal Office for Building and Regional Planning was completed in 2010.
Separate air-conditioning systems were joined into a single AC-unit. It can produce an output of 1,5 MW. The used cooling power coming from the well is 1,4MW. Additionally, a total amount of 5,4 MW of heat can be produced.
