Energy Savings
As an energy saving house is called not a specific design concept, but any building that requires less energy for heating and hot water has one, as the energyin their data sets for maximum permitted values
Such construction not only protect the environment but in the long term view on the pocketbook. In addition you get for low-interest loans. A prefabricated building is well suited, since dry wood construction and the many layers of insulation provided by an excellent thermal insulation is.
The following building concepts describe energy efficient homes:
- Low energy house
- KfW 60 house
- KfW 40 House
- 3-liter house
- Zero-energy house
- Passive house
- Plus Energy House
Low-energy buildings consume about 20% less annual primary energy than the average. Your transmission heat loss should be at least 30% lower than that of a building of similar size.
KfW 60 houses have a maximum annual primary energy consumption per square meter of 60 kilowatt hours. The transmission heat loss should be lower than usual for low-energy houses at least 30%.
40 houses at KfW may the annual primary energy demand can not exceed 40 kilowatt hours per square meter. In addition, the transmission heat loss of at least 45% lower than required by the Energy Saving Ordinance.
3-liter house need of primary energy per square meter per year, only the amount of energy that goes into 3 liters of fuel oil.
Passive houses do without active heating and ventilation system, but primarily use the heat of solar radiation, and the persons or electrical equipment comes from. This will save you in a passive house compared to a conventionally built house over 80% of annual primary energy.
Zero energy buildings require an annual average of no net energy supply from outside. This is a zero-energy house more efficient than passive houses, but their preparation is quite expensive.
Plus energy houses are even by the fact that average annual net energy delivered to the outside in, so a bit if you have a special build prefabricated houses like
Plus energy houses are even by the fact that average annual net energy delivered to the outside in, so a bit if you have a special build prefabricated houses like
- Increased thickness of insulation in the exterior walls.
- Increased insulation in the roof and on the top floor ceiling to an undeveloped attic.
- Insulating protection in the basement ceiling.
- Minimize or - if possible - avoid heat bridges.
- Economical drives home technology.
- Economical drives home technology.
- Any additional heating for the supply air to the ventilation system.
- Ventilation system with controlled ventilation, which goes back much of the heat from the exhaust air.
- Installation of a solar thermal system to support the hot water supply.
- High air-tightness.
Use natural lighting whenever possible. If you do a lot of reading in the study, the plan of having a large window that fills the room with light and eliminate the need for the day of a lamp. Similarly A skylight over the kitchen island offers task lighting, press the switch without overload. Energy efficient, compact fluorescent bulbs.Installation of high efficiency lighting and lighting controls, like dimmer switches and motion sensors. Consult a professional to select an appropriate size heating / cooling for your home. If the ISN system, Aot large enough to accommodate the size of your home that will run more frequently result in inefficiency. Create a building envelope using thermally efficient R value ceiling and wall insulation. Avoid use of glass in the east and west sides of the house. Install energy efficient windows, such as argon or gas-filled triple-pane windows. In addition to selecting vinyl or wood frames instead of traditional aluminum frames, as these two insulating materials against doing better temperatures outside air y. Choose appliances such as refrigerators and clothes dryers that are ENERGY STAR.
