The future builds ecologically. Today, the resources of the environment are also used optimally at home. In the energy-saving house, form and function are at their best.

Passive houses combine the best of decades of experience in energy-efficient construction. The architects of the passive houses are experts and builders, compared to the conventional design at least 85 Save percent of energy costs.

Builders have always tried insulation, Seals and multiple glazed windows to defy the weather conditions: The windows became smaller and smaller and the masonry thicker and thicker. Schimmel, a bad climate and unfavorable lighting conditions are often the result.

85 Percent of the energy costs are used for heating and hot water preparation. With rising energy prices and the natural depletion of global raw material supplies, there is no sign of an end to this price spiral.

The energy-saving house - that's how it all began

It all started with the low-energy house and the energy-efficient houses. But modern techniques and findings in architecture and construction reveal new perspectives. Today's energy-saving house builds on nature - by building with nature. Depending on the construction method and savings potential, the energy-saving house can be divided into different categories:

– Low energy house
A maximum of 7 Liters of heating oil or 70 Kilowatt hours per square meter of heating energy are consumed. Many of the prefabricated properties offered are already low-energy houses. Renovated or refurbished buildings can also achieve this standard at a later date with suitable construction measures.

– 3-Liter house
The 3-liter house is even more economical, this annually with at most 3 Liters of heating oil or 34 Kilowatts per square meter have to get by.

– KfW's efficiency houses
The energy-saving houses of the credit institute for reconstruction are divided into different classes according to their maximum values ​​in primary energy consumption. The KfW efficiency house 70 (EnEV 2009) may be highest 45 Consume kWh / qm, with a primary energy requirement of up to 70 percent. Components such as transmission losses in district heating are included in the calculation of the primary energy demand, Energy requirements of the machines used and the energy content of the carriers (coal, mineral oil, Natural gas etc.) a.

– Live harmoniously in a passive house
The construction of passive houses is subject to strict legal regulations. With a heating requirement of the highest 15 kWh per square meter, the framework is narrowly defined - entirely to the benefit of the client. Because this means that the energy costs in passive houses are limited to a heating requirement of at most 15 kWh / sqm (1,5 Liters of heating oil) limited. Without any conventional heating, the passive house creates a pleasant room climate all year round. The passive use of the energy generated in the house, the unique construction in harmony with the natural incidence of light and a sophisticated automatic loading- and ventilation system with a highly efficient heat exchanger make the passive house a real saver in the long term - even if the construction costs are initially a little higher. But savings can also be made on the purchase price: KfW Bankengruppe generally supports passive houses with a repayment subsidy of 5 Percent and also many states and municipalities support the passive house.

Passive houses - nature and practicality

The timber construction is particularly popular with builders, which in the energy-saving house implements clear and minimalist lines just as appealingly and timelessly as the classic architectural styles. The energy-saving house concept in the wood panel construction is not only convincing due to the short construction times, a contemporary one, attractive architecture and high durability, but also through the enormous savings in the energy sector. Passive houses have long since become an integral part of a modern and sustainable building concept. With a heating energy saving of 80 to 90 Percent and a continuous supply of fresh air, builders in the passive house not only expect a high level of living comfort with low monthly energy costs, but also the building concept of the future.
