Energy costs reduced by half a million euros

06.08.2012
An energy efficiency program at the Siemens site in Kemnath in Bavaria has reduced annual energy costs by 20 percent, or more than €500,000.

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.

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
