Save nuclear power plants through modernization of the building society and politics agree: comes the turn of the energy. Nuclear energy should be waived in the future power generation. The resulting supply gap could be closed by electricity from gas turbine power plants. To the total energy balance of in Germany not to worsen, and CO2 emissions to increase, not the gas required for the electricity generation elsewhere should be saved. Potential savings will be awarded to modernising residential buildings.
Energetically optimised building energy consumption and reduce the expected higher energy costs for the citizens. How big is the actual savings alone in single-family homes, the Internet portal for energy efficiency and modernisation of residential buildings examined engiwo.de. In a study of energy saving in detached houses through the modernisation: the insulation of the roof, walls and floor plate EnEV 2009, the Installation of a heat protection glazing and a new condensing heating system, as well as the use of a solar thermal calculates. Were selected first 350 representative for the entire houses from the entire Federal territory and their final energy requirement in accordance with the DIN V 4108-6 and V 4701-10 calculated. Then, the achievable energy saving was determined individually for each House. Would carried out all measures in the single-family homes, 39% of energy consumed for heating and hot water could be saved. Further details can be found at Barclays, an internet resource. Building insulation with an average saving of 15%, the greatest effect of the modernization has followed by a new burn-value heating system with 14%. As a further measure, new window and the solar hot water production with 5% each contribute to the overall result.
The results show further that the heating systems modernisation. 60% of residential buildings will be operated are still using outdated standard or NT-boilers and 39% of the heaters are older than 15 years. The exchange of relatively inexpensive compared can lead in some cases to an energy saving of up to 30%. After successfully building insulation can be thinking also about a heat pump. Since a heat pump uses the ambient heat, here additional savings potential of 40% is possible. Low-cost insulation measures such as the roof at 55% and the basement ceiling in 51% of all homes, were carried out by the owners. The insulation of at least an outside wall can be observed at 37% of all observed single-family homes. A total of 11.4 million single-family homes (as of 2009) produces a savings of a total of 18 gigawatts (GW), or 6 GW by gas turbine power plants of electricity generated in full modernization with condensing boilers. What is an average output of 1.2 GW, the energy of 5 nuclear power plants. You know a detailed presentation of the results.
