An Energieeinsparverordnung is understandably more expensive than a house building according to the “EnEV” regulations. A bottom plate down-insulated, triple insulation glazing and a higher insulation of pitched of roof represent an expense that must be paid, but ultimately worth. Finally, quality has its price! Seen in the long term an Energieeinsparverordnung has considerable advantages. What you’re now investing savings in the future. Zero-energy buildings, passive houses and Plusenergiehauser a passive house requires as a further development of the low energy House substantially less energy for heating and hot water than a conventional new construction. The compact structure is characteristic of passive houses, the living rooms facing South ideally.
The sunlight can be effectively used in this manner. A passive house has an air and wind-proof building envelope that is insulated and free of thermal bridges. The cold outdoor air does not penetrate into the energy, the hot indoor air is prevented from leaving the building. Among other things an innovative three-pane glazing is responsible. The frame is insulated, so that the window to absorb solar energy, which is then stored in the walls.
A special ventilation system provides fresh air. Who owns a passive house, may waive mostly a conventional heating system. Drinking water heated by solar panels or heat pump. A more efficient energy is the zero-energy House. The external cover of the energy is completely absorbed in this case by the own energy gain, for example by a solar system. Zero energy homes have large, pointing to the South and at the same time unbeschattete window surfaces. The ratio of surface to volume conversions low. The facade, the roof, the Windows and the doors have a high insulation value. The building is largely sealed. The zero-energy House is the evolution of the passive house. In addition there are also buildings that produce more energy than they need. In this case, one speaks of a so called plus energy House. These houses are even no external power, but completely self-sufficient. A Hybridhaus hybrid homes causes no heating and energy costs. For example photovoltaic systems available are for energy production. Among other things a special geothermal technology is generating heat. Those who opt for a Hybridhaus, requires neither gas nor oil and fueling climate-neutral. The hybrid homes are highly isolated.
