The gas- and oil prices have risen sharply recently, and economic experts predict further growth. In this situation, more and more people are choosing an energy-saving house. Such a house should comply with the provisions of the Energy Saving Ordinance, its primary energy requirement should in any case 60 Do not exceed kWh per square meter.
If you want to have an energy-saving house built, then you can rely on government funding- and resort to loan programs (z.B. from KfW), that supports environmentally friendly living. Such a house costs more, than a traditionally built house, but in the end you will save your additional costs with the house, because the heating- and electricity costs remain low.
Effective energy saving is possible thanks to the good thermal insulation with innovative materials. The outer walls and the roof are thoroughly insulated in several layers, so that there is practically no heat loss to the outside. In addition, instead of double glazing, triple glazing is used in the windows of an energy-saving house. Floor heating is often installed in an energy-saving house, which effectively and thoroughly heats the rooms.
The modern photovoltaic systems make the energy-saving house independent of conventional energy, the energy can be stored and used as required. In summer, the solar cells can also serve as air conditioning. In addition, modern heat pumps can be used in a low-energy house, use geothermal heat for heating. The residual heat from the wastewater is also effectively extracted again in a low-energy house and used for heating, this creates a heat cycle, in which heat losses are minimized.
In any case, only energy from renewable sources is used to heat an energy-saving house.
A special type of energy-saving house is a so-called. Zero energy balance house, that is, a building, in which no additional energy has to be drawn from the outside for longer periods of time, to make the house habitable. Such houses are now only made individually and are not mass-produced.
In an energy-saving house or a zero-energy balance house (a passive house) there are no relevant disadvantages to be named. If you want to have such a house built for you, From now on you will not only care about the sustainable treatment of your environment, Your monthly budget is also permanently relieved by the low heating costs.
