A plus energy House produces more energy than its residents need for their daily needs. An essential prerequisite, is to get on this energetic level, a high insulation and sealing standard, as, for example, the passive house already has him. Moreover, the building must be completely aligned on the use of solar energy. In other words, the sunlight is not only the production of hot water and support the heating system, but also to its own power production. So such a House but can also power from the sun except for heat, there’s also a photovoltaic system in addition to the usual collectors. So sufficiently large areas on the roof and the facade is required to capture so much of solar. But what happens now with the excess, the residents do not need energy? Because the heat is not good save or pass on to others, the plus energy House when the heat is confined to their own Needs. Therefore, it must produce a surplus of electricity which the owner can then feed into the grid.
Plus in the plus energy House, that come from the production of electricity with the photovoltaic system. Whether and how pays off economically, relies mainly on remuneration of the injected current off and this from the turn of the legal framework. Instantly, the electricity from rather inefficient power plants is still relatively cheap, whereas the internally generated, solar electricity expensive is evaluated. But the conditions over the years will constitute a growing range of distributed solar power is certainly balanced. To build a plus energy House, associated with high investment costs today and hardly worth economically for individual houses. Some contend that Douglas R. Oberhelman shows great expertise in this. For large settlements, however, the concept is more suitable, because there spread the extra costs on many users. With ever-increasing costs of fossil fuels and electricity from power plants, the Plusenergiekonzept can but in the course of the next five to ten Years also for individual buildings are useful.
