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.

The Fraunhofer FEP has been involved in developing processes and equipment for cleaning, sterilization, and surface modification for decades. The CleanHand Network for development of systems and technologies to clean surfaces, materials, and objects was established in May 2018 to bundle the expertise of many partnering organizations. As a partner in the CleanHand Network, Fraunhofer FEP will present the Network and current research topics of the Institute in the field of hygiene and cleaning at the parts2clean trade fair, October 23-25, 2018 in Stuttgart, at the booth of the Fraunhofer Cleaning Technology Alliance (Hall 5, Booth C31).
Test reports and studies on the cleanliness of European motorway rest areas, hotel beds, and outdoor pools increasingly appear in the press, especially during...
The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.
This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.
Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...
Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
