Energy-saving houses are becoming increasingly popular, which is particularly due to the high savings potential. Although the initial construction costs are higher than those for a "normal house", but the later operating costs are many times lower. There are many reasons for this. For example, the particularly good insulation, which can save a lot of heating costs later.
In addition, energy-saving houses are recognized for their modern energy recovery. So-called heat exchangers are necessary for this, which both of the exhaust air, as well as withdraw the residual energy from the wastewater and then channel it into the heating circuit.
Regardless of the heating power savings, energy-saving houses are equipped with environmentally friendly alternatives for generating energy. For example with a photovoltaic system, which is mainly responsible for the generation of electricity and / or with a solar system, for heat production. Both photovoltaic systems and solar systems obtain their energy from the sun, which is available to the resident at any time free of charge. With the help of a photovoltaic system, energy can also be fed into the local grid. The respective network operators pay a corresponding fee for each kilowatt hour fed in.
Types of energy saving houses
There are now different types of energy-saving houses. The best known is the so-called passive house. The passive house mainly uses passive energy sources. For example, the waste heat from electrical devices or people. The energies are collected by the passive house, converted and used to heat the interior. Furthermore, a passive house usually has very large windows, allowing more sunlight to warm up.
In addition to the passive house, there is also the low-energy house, which is characterized by a particularly low energy consumption. In a low-energy house, optimal thermal insulation is particularly important. The zero energy house is particularly interesting, which gets its energy exclusively by itself and does not depend on any additional alternatives.
Another possibility is the 3-liter house, at which annually, per square meter of living space, a maximum of three liters of heating oil can be used. Here, too, optimal and effective thermal insulation plays an essential role.
The pulse energy house is an absolute innovation in the field of energy-saving houses. The pulse energy house feeds more energy into the local grid every year, than it needs itself. Optimal thermal insulation is crucial for this, the use of heat pumps and solar systems as well as excellent ventilation systems and heat exchangers.
