The program will repay its investment costs of €1.9 million in about four and a half years. At the same time, the location now emits one fourth less carbon dioxide - a reduction of more than 2,700 tonnes.
This is the amount of CO2 that would be produced by approximately 18 million kilometers of automobile driving. Siemens Healthcare employs 1,100 people in Kemnath. The ultramodern manufacturing site there produces components for magnetic resonance imaging, CT scanning, and radiography, among other applications.
Since 2006 Siemens has been identifying energy-saving potential at its own facilities and adopting efficiency measures to tap into that potential. More than 100 of the company's 300 plants have already undergone the Siemens Energy Health Check. As a result, electricity consumption at the production facilities declined by 11 percent on average between 2006 and 2010. At the same time, their efficiency with regard to primary energy and district heating increased by almost one fourth.
The savings in Kemnath were due to four steps. Instead of the old gas boilers, biomass boilers that use wood chips as fuel are now supplying the necessary heat. An extra gas boiler is used to manage peak loads. Electricity is supplied by a natural gas cogeneration unit that simultaneously produces heat. The new heating technology was responsible for over 60 percent of the cost savings. In addition, fans and pumps for the air conditioning systems were made adjustable with the help of frequency converters.
Now carbon dioxide sensors measure the air quality, and the ventilation system is adjusted as needed. Savings also result from the use of the latest generation of energy-saving fluorescent lamps, which are automatically dimmed on the basis of input from daylight sensors and motion detectors. Finally, all the buildings are now connected to a completely renovated, efficient central cooling system.
Siemens is one of the world's leading suppliers of green technologies, and the company brings this expertise to bear at its own business locations too. Environmentally friendly and energy-efficient products and solutions are part of the Siemens Environmental Portfolio, with which the company generated about €30 billion in sales in business year 2011.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
