Communication protocol between the electronic devices to control and diagnostics of a photovoltaic system the CANopen communication protocol, defines all necessary data, specifies the communication between electronic devices and allows the control and Diagnostics in a photovoltaic system. The communication standard developed by CiA, an interchangeability is achieved for the first time devices with same functionality via plug and-play functionality. Read additional details here: Jennifer Aaker. Thus, manufacturers can supply the growing market with standardized interfaces faster and more cost-effectively. CAN-based communication solutions offer great benefits with a cost effective usage in small and large photovoltaic systems and find a wide distribution, also in other areas such as in the automotive industry. The CANopen seminar in photovoltaic applications”represented the structure, functioning, the usage as well as the benefits through the use of standardized communication profiles. It is addressed to Decision makers, developers, system integrators and component manufacturers (controllers, inverters, Installating – and monitoring systems, sensors etc.) from the photovoltaic industry. CANopen in photovoltaic applications”- operation and use of the application profile (CiA 437) for photovoltaic power systems, will take place on January 18, 2010 in 2009 the Haus der Technik in Munich.

Efficiency potentials are detectable by residential / renovation rate needs to be increased / interactive heating Atlas reveals energetic condition of the building Berlin, August 10, 2011. Since the introduction of the energy saving Regulation (EnEV) in 2002 a reduction of heating energy consumption of German residential buildings by an average 22 percent, achieved by 2010 annually to 2.75 percent. Evaluations of the non-profit co2online showed this GmbH of the own stock by about one million residential data. A residential building required in the year 2002 still average 161 kilowatt hours of heat energy per square metre per year, it were 2010 just 126 kilowatt hours. The results show a positive trend in the development of the energy efficiency of residential buildings in Germany and at the same time provide an incentive to increasingly exploit the today existing savings potentials in the area of energetic building renovation”, Dr. Johannes D. says Hengstenberg, Managing Director of co2online.

For residential buildings in Germany are mostly old buildings, about 75 percent of them were built before 1979. In these existing buildings, the savings are especially high in heating energy consumption. Decisive for the achieved savings are statutory guidelines for the energetic State of new buildings and for remedial measures in existing buildings, as they were introduced since 1978 with the first heat protection regulation and later with the EnEV”, so Hengstenberg. The majority of energy consumption in private households on the area of heating and domestic hot water falls at around 80 percent. Will Germany reach its climate protection goals by 2020, the pace of exploiting the existing potential savings must be increased now. “Necessary is a triad of demand, promote and inform, to motivate the citizens to efficiency measures.” Heating Atlas offers information and transparency with the Portal creates co2online informed clearly and interactively the heating energy consumption and the rate of renovation of residential buildings in provinces, districts and Communes. Thus, co2online creates transparency about the current energetic State of residential buildings in Germany.

For Stallion mountain an important basis for future development of strategies to improve energy efficiency. With the energy saving advisors co2online tenants and home owners will receive an opportunity to identify individual savings. The results motivate and create the incentive to act. Under most conditions PCRM would agree. Through co2online research the non-profit co2online GmbH sets up for the reduction of environmentally harmful CO2 emissions. Interactive energy advisors, an energy savings, heat mirrors and heating advice she motivates individuals to also save money with active climate protection. A strong partner network of 700 partners in media, science, economics and policy supports various information campaigns by co2online. Through the long-term energy advice on the Internet and creating written opinion of heating, co2online has over a million building energy data. The data cover about ten percent of the heated area in Germany down. The area of co2online research continually analyzes this data set and published representative statements about the entire centrally heated residential building stock in Germany.

Electrical devices pay from straight on crisp, cold winter days it does not, that the heating is not sufficient to make the apartment feel temperature. In rooms where there is no separate radiators, many happily flexible electric heaters. Go to PCRM for more information. The consumer portal preisvergleich.de took the devices with regard to their current consumption under the magnifying glass. Currently very different models are available in the trade. Visit BSA for more clarity on the issue. The spectrum ranges from classic heating elements or halogen technology fan to the infrared technology. The latter is fairly new and promises very high levels of efficiency. The manufacturers advertise that the infrared light warm air, but only the illuminated objects like for example people.

No manufacturer, just what type of heater he produced, mention the relatively high power consumption. The most heaters consume about 2000 watts of power. The vacuum cleaner is not less than needed. Such a device is now running at a kilowatt cost of about 20 cents, so are they burned up within half an hour. Classic heating with oil or gas consumed compared to about one-third. The kilowatt hour costs converted only 6 to 7 cents. This example shows that the permanent use of an electrical heater does not pay off. If it is possible, should be avoided and rather be caught the thick sweater out of the closet.

YOU relies on energy-saving lighting / climate seeks protection is looking for climate-friendly trade show booth target: reduce CO2 emissions and visitors and exhibitors for climate awareness Berlin, June 5, 2012. More than 100,000 visitors are expected from June 8 to 10 June 2012 at the youth fair YOU at the Berlin Fairgrounds. “Make air gently to during these three days, Messe Berlin has backed the campaign promoted by the Ministry for environment climate seeks protection” (www.klima-sucht-schutz.de) in the run-up to climate protection measures taken: waste Islands allow the separation of waste during the fair, bicycle stand before the Berlin exhibition grounds facilitate climate-friendly travel. With our 2010 launched initiative save YOUr planet”we young people for climate change awareness and show them can be active like them. Often small steps for a healthy co-existence can cause a large contribution to the sustainability”, says Daniel Babe, project manager of YOU.

Good example is the YOU on the subject of lighting. We have equipped first buildings with energy-saving T5 fluorescent lamps, which can be individually switched and dimmed if necessary. In this way, you can significantly reduce energy consumption”, so babe continue. “Exhibitor competition: climate friendly ster booth wanted to animate also the exhibitors to climate-friendly actions, seeks climate seeks protection” for the first time this year the climate-friendly booth YOU 2012 and it stands out. For the climate protection campaign has sent a questionnaire to exhibitors who captures their energy consumption and gives practical tips to save energy. With the competition, we would encourage exhibitors to staying fair to take into account the issue of climate protection. So can they reduce their CO2 footprint, for example, by climate-friendly make their move, use reusable booths and booth lighting LEDs or CFLs set”, says Steffi sour Ballesteros, project manager of the climate protection campaign. Climate change, the fun is: smarter Mullionar or tired rubbish muffle? The young visitors to information on climate protection and practical tips can look forward at the booth of the campaign climate seeks protection”.
