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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
