Constant growth in all areas of the company led in 2006 to the decision to build additional office space at the headquarters in Bad Berleburg. The goal here was to create a workspace for our employees that corresponds to our company spirit: motivated solutions, constructive logic, and spatial freedom.

The two options considered were the conversion of old production areas into offices or constructing a new office building next to the existing complex. Architectural and organisational considerations finally led to the decision to build a free-standing building in Bauhaus style, characterised by an extensively glazed façade.

A three storey, highly modern building with 1,200 m² of office space was built in an extremely short construction time of just 7 months. Since November 1st, 2007 this building has housed 60 employees of Controlling, Facility Services and general management.



For instance, 15 holes bored to a depth of approximately 100 metres contain pipes that transport heat to or from the ground. The regulation system determines the necessary energy balance and either draws heat from the ground or transfers heat down into it. The ground thereby serves as an energy reservoir that makes energy stored there during the summer available during winter months.

Naturally all shutters, temperature controls, lighting, ventilation system and the needs-based heat and cooling supply are automatically energy-optimised and regulated by an OTTO automation & control system.

With this building, the company continues to invest in the Bad Berleburg location. We also would like to thank our employees for their unflagging commitment.

Pratt & Whitney is one of the world’s leading manufacturers of aircraft engines.

OTTO Engineering Polska S. A. was commissioned in November 2007 with the setting-up of production rooms for high-tech casting technology within an existing plant hall at the Rzeszow site in Poland. OTTO Engineering Polska S. A. acts here as technical general contractor.

The scope of services includes the delivery, installation and start-up of a room-in-room system with all associated media technology. A precision climate must be maintained in the future production rooms with regard to temperature and relative humidity, which must be kept within very narrow tolerances ranges year-round for product-specific reasons.

OTTO Engineering Polska S. A. is responsible for the following areas:

• Ceilings and walls
• Steel structures and platforms
• Climate control
• Pollutant detection and control
• Cooling
• Heating
• Water supply and wastewater disposal
• Lighting
• Measurement and control technology (automation systems)
• High- and low-voltage electricity

Marburg – In October 2007, Federal Chancellor Angela Merkel opened the world’s first large plant for production of flu vaccines from cell cultures in the Marburg Behringwerke. OTTO Clean Systems participated in the building of this plant.

The new technology will make it possible in future to react more quickly and flexibly to changes in flu viruses and still rapidly produce vaccines at industrial scales. In contrast to the traditional methods for producing vaccines, the cell culture technology does not require incubated chicken eggs. This is an enormous advantage, particularly in fighting bird flue as well as in the event of a possible flu pandemic.

According to information from the technical director of Behringwerke, Norbert Klein, the production time for a vaccine in the event of a pandemic can be halved from four to six months to between two and three months.

Technical details:

The seven-storey building is supplied by a 580 m² ventilation plant via fourteen HVAC systems: three BSL3 systems (Bio Save Level/safety class 3), six full climate systems and five ancillary systems.

The HVAC systems ventilate approx. 3,500 m² of building area, consisting of 370 m² BSL3 area, 150 m² rooms with clean room class C, 630 m² rooms with clean room class D as well as 2,350 m² support and technical areas.

This is realised by an air duct system with a duct and fitting area of 7,100 ² supplemented by 1,500 m of pipes and 308 filtered outlets.

The total output of the HVAC systems is 142,000 m³/h. The output values of the air treatment units are 1,800 kW for hot water, 1,400 kW for cold water and 925 kg/h for clean steam moistening.

The control and monitoring of the regulatory processes such as room pressure regulation, temperature or humidity monitoring in the production and laboratory areas are handled centrally via DDC (Direct Digital Control) and are important components of the technical facility management.
